13 Books for 2020 – What A Year!

2020 is turning into quite the publishing year.

Perhaps every year is like this and I just haven’t been paying attention before. Now, as I actively scan publisher sites and newsletters for upcoming books, there seems to be an abundance of super-interesting new stuff: how is anybody – even someone like me who does this for a living – supposed to keep up?

#1: The year began at full (or stagnating…?) speed with University of Houston professor Dietrich Vollrath‘s Fully Grown: Why a Stagnant Economy is a Sign of Success, With praise by Tyler Cowen and reviews in The Economist and the Wall Street Journaland actually a lot of good discussions on Twitter – I’m sad that I haven’t taken time to read it. Later, perhaps, on the off-chance that nothing else on this incredible lists comes in the way.

#2: Next up was Diane Coyle‘s Markets, State, and People. Coyle, the endlessly interesting public intellectual/economist and newly(-ish) appointed Professor of Public Policy at Cambridge, is someone we all should read: she manages to be controversial and still balanced, provocative but still interesting. This book, however, seems to be in line with all the other “Third Way” books of last year: Acemoglu and Robinson’s The Narrow Corridor; Raghuram Rajan’s The Third Pillar; Branko Milanovic’s Capitalism, Alone. Crowded field. As I haven’t even gotten around to her previous book on GDP yet, I imagine I’ll read that one first whenever I carve out some time for Coyle.

The curse of modernity is quickly adding up.

#3: Changing gears somewhat at least in terms of topics I have started reading Charles Murray‘s Human Diversity: The Biology of Gender, Race, and Class and it’s exactly as provocative as you might think. Delivered, however, with the seriousness of scientific investigation and a massive chip on his shoulder. Still, exactly the kind of antidote to madness that fuels a lot of my priors. I’ll write up a comment or two whenever I finish this 528-page tome.

#4: In a similar vein is the Dutch writer and historian Rutger Bregman‘s Humankind: a Hopeful History, scheduled to be released in June. As Bregman isn’t somebody that I usually agree with, I’m very excited to read this take of his, which is hopefully a mix of Paul Bloom’s End of Empathy, Ruth DeFries’ The Big Ratchet and Paul Seabright’s The Company of StrangersSort of like Yuval Harari’s Sapiens but better (and no, I’m not on Team Harari despite this excellent long-read in The New Yorker).

#5: Going back a little bit to what I think is chronologically the next book to be released (on Tuesday March 10 in the U.S., but not until April in the U.K.) is Robert Bryce’s A Question of Power: Electricity and the Wealth of NationsHaving recently written a piece on electricity generation and being into the weeds about climate change and emissions, I’m very curious about this take on electricity as a critical source for our prosperity. I hope it reads a little like an improved version of Zubrin’s best chapters in Merchants of Despair.

#6: March is also the month for Angus Deaton and Anne Case‘s Deaths of Despair and the Future of Capitalism (Amazon says it’s already out in the U.K.) Their hugely successful and highly relevant pet project for the last few years, Deaton and Case’s case(!) for how rising morbidity rates indicate a collapse of the fabric of society is a pretty standard one by now: globalization, economic inequality, the hollowing-out of tight-knit communities and the various forces that may have fueled this.

The reviews are already popping up left and right (WSJ, Financial Times) and their session was the most exciting and most talked-about at the ASSA meeting in San Diego. As I understand it, the latest findings is that American life expectancy that pesky ever-increasing number that fell in recent years, in no small part due to overdoses and opioids has recovered and is now again on the up-tick. Maybe Deaton and Case’s book will be one for an odd historic event rather than foreshadowing “The Future of Capitalism” (also, what’s up with shoving ‘Future of Capitalism’ into your titles?!).

#7: In a similar topic, Robert Putnam yes, the Harvard professor famous for Bowling Alone and the idea of social capital is back with another sweeping analysis of what’s gone wrong with American society. The Upswing: How America Came Together a Century Ago and How We Can Do It Again, coming out in June, is bound to make a lot of waves and receive a lot of attention by social commentators.

#8: Officially published just yesterday is John Kay and former Bank of England Governor Mervyn King‘s Radical Uncertainty: Decision-Making for an Unknowable Future. Admittedly, this is the book I’m least excited about on this list. Reviewing King’s 2016 End of Alchemy where King discussed his experiences of the financial crisis and the global banking system for the Financial Times, John Kay discussed exactly that: the title? “The Enduring Certainty of Radical Uncertainty.” Somebody please press the snooze button. Paul Krugman’s 4000 word review of End of Alchemy ought to be enough; I’d be surprised if Kay and King brings something new to the table in thus poorly-titled release (though, of course the fringe already loves it).

The Really Good Stuff

While the above eight titles are surely worth at least some of your time, the next five are worth all of it.

#9: I’ll begin with my two biggest hypes: Matt Ridley‘s How Innovation Works: And Why It Flourishes in Freedom, coming out May 14th in the U.K. and May 19th in the U.S. The author of The Rational Optimist and The Evolution of Everything is back with another 400-page rundown of a deep-seated and hyper-relevant topic: how do societies innovate and progress? What conditions assist it, and which obstacles prevent it? 

I expect a lot of spontaneous order-type arguments, debunked Great Man fallacies, and some Mariana Mazzucato take-downs.

#10: The second hype, William Quinn and John Turner‘s Book and Bust: A Global History of Financial BubblesSince John first told me about this book over a year-and-a-half ago, I’ve been super excited – I’m a big fan of his work and I’m looking forward to receiving my review copy in the next couple of weeks. Publication date: August.

#11: For somebody who writes about bubbles and financial markets more than most people think healthy, I’m gonna get a warm-up in MIT professor Thomas Levenson‘s Money for Nothing: The South Sea Bubble & The Invention of Modern CapitalismWhat’s with all these books on historical financial bubbles? Yes, you’re right: 2020 marks the three-hundred year anniversary of the South Sea Bubble, that iconic period of John Law in France and the similar government funding scheme in England will surely receive a lot of attention this year.

#12: Some environmental stuff at last: Bjørn Lomborg, the outspoken author and voice of reason in the climate change space announced that his False Alarm: How Climate CHange Panic Costs Us Trillions, Hurts The Poor, and Fails To Fix the Planet will be published in June this year! While possibly the least boring book on this list, the title receives lowest possible marks. What overworked publisher decided that this page-long subtitle was a good idea?!

#13: Also, Alex Epstein of the Centre for Industrial Progress and host of Power Hour (one of my all-time favorite podcasts) has been working on an update to his hugely popular The Moral Case for Fossil Fuels. As far as I understand, we’re to receive an updated and revised version in August the Moral Case for Fossil Fuels 2.0!


So. The next six months have at least thirteen pretty interesting books coming up. I imagine there are a bunch more for the rest of the year and a few I have completely overlooked.

Also, after this burst of links, Amazon should probably offer Notes On Liberty an affiliate program.

In sum: you can see my fields of interests overlapping here: (1) financial history and financial markets; (2) environment, climate change, and its solutions; (3) Big Picture society stories, preferably by interesting or quantitatively savvy authors. Not enough on the fourth big interest of mine: (4) money and monetary economics – particularly in historical contexts. Perhaps not, as David Birch’s Before Babylon, Beyond Bitcoin is on my desk, and I’m currently re-reading William Goetzmann’s Money Changes Everything both first released in 2017.

Also: the absence or underrepresentation of women (or ethnic minorities or any other trait you care a lot about) might disturb you: 2 out of 17 authors women (4 out of 27 authors mentioned) Needless to say, it must be because I’m sexist.

Post-script: Ha! As I just heard about Stephanie Kelton‘s upcoming book The Deficit Myth: Modern Monetary Theory and the Birth of the People’s Economy, I’m gonna quickly add it to the list and satisfy both of my qualms above: not enough women (now: 3/18 authors!), and not enough monetary economics. Splendid!

Happy reading, everyone!

Sunday Poetry: Rüstow vs. Mises

One of the bests books I’ve read this year was Serge Audier’s & Jurgen Reinhoudt’s relatively unknown (unfortunately!) translation of the protocols of the Walter-Lippmann-Colloquium. The NOUS-Network organized a wonderful seminar in which we thoroughly discussed the book and the emergence of Neoliberalism. For the preparation of this weekend’s Hayek-Kreis seminar, I reread the book and stood once again in awe of the magnificence of the discussion during the Colloquium.

By the way: If you are an undergraduate, graduate, or PhD scholar, please consider joining the NOUS-Network for Constitutional Economics and Social Philosophy as a Young Affiliate! NOUS is an information platform and a community for interdisciplinary research. The network links all academic fields relevant for thinking about social order and liberty. It spans philosophy, politics, economics and fosters scholarly research, contact and exchange.

In the following excerpt, it becomes clear, that the participant’s opinion on the psychological and sociological causes of the decline of Liberalism differed significantly. Mr Rüstow eloquently captures the standpoints of the two opposing groups (not without bias to be fair) and even cheekily disses Ludwig von Mises.

“Mr Rüstow: ‘All things considered, it is undeniable that here, in our circle, two different points of view are represented. One group does not find anything essential to criticize or to change in traditional liberalism, such as it was and such as it is, apart from, naturally, the adjustments and the current developments that are self-evident.

In their view, the responsibility for all the misfortune falls exclusively on the opposite side, on those who, out of stupidity or out of malice, or through a mixture of both, cannot or do not want to discern and observe the salutary truths of liberalism. 

We, on the other hand, we seek the responsibility for the decline of liberalism in liberalism itself; and, therefore, we seek the solution in a fundamental renewal of liberalism. In order to justify in a positive manner this second point of view, I have to refer to what I have said and, especially, to the excellent arguments of Mr Lippmann.

Here, I would only like to draw attention to the fact that if the unwavering representatives of old liberalism were right, the practical prospects [for liberalism] would be almost hopeless. Because it does not really seem that old liberalism has gained in persuasive and in seductive force or that the arguments, no matter how shrewd they may be, of these representatives have the least possibility of bringing about a conversion movement within the realm of Bolshevism, Fascism, or of National Socialism. If they did not listen to Moses and the prophets—Adam Smith and Ricardo—how will they believe Mr. von Mises?'”

As always, I wish you all pleasant Sunday.

 

On Translating Earnings From The Past

A few days ago, John Avery Jones published a great piece on the Bank of England blog (“Bank Underground”), investigating how much Jane Austen earned from her novels in the early 1800s. By using the Bank’s own archives and tracking down Austen’s purchases of “Navy Fives” (Bank of England annuities, earning 5%), Avery Jones backed out that Austen’s lifetime earnings as a writer was probably something like £631 – assuming, of course, that the funds for this investment came straight from the profits of her novels.

Being a great fan of using literature to illustrate and investigate financial markets of the past, I obviously jumped on this. I also recently looked at the American novelist Edith Wharton’s financial affairs and got very frustrated with the way commentators, museums, and scholars try to express incomes of the past in “today’s terms”, ostensibly vivifying their meaning.

For the Austen case, both Avery Jones and the Financial Times article that followed it, felt the need to “translate” those earnings via a price index, describing them as “equivalent to just over £45,000 at today’s prices”.

Hang on a minute. Only “£45,000”? For the lifetime earnings of one of the most cherished writers in the English language? That sounds bizarrely small. That figure wouldn’t even pay for the bathroom in most London apartments – and barely get you a town-house in Newcastle. The FT specifically makes a comparison with contemporary fiction writers:

“[Austen’s] finances compare badly even with those of impoverished novelists today: research last year by the Authors’ Licensing and Collecting Society found that writers whose main earnings came from adult fiction earned around £37,000 a year on average”

Running £631 through MeasuringWorth’s calculator yields real-price estimates of £45,910 (using 1815 as a starting year) – pretty close. But what I think Avery Jones did was adjusting £631 with the Bank’s CPI index in Millenium of Macroeconomic Data dataset (A.47:D), which returns a modern-day price of £45,047 – but that series ends in 2016 and so should ideally be another 7% or so from 2016 until May 2019.

 “This may not be the best answer”

Where did Avery Jones go wrong in his translation? After all, updating prices through standard price indices (CPI/RPI/PCE etc) is standard practice in economics. Here’s where:

untitled-1

The third line on MeasuringWorth’s result page literally tells researchers that the pure price number may not reflect the question one is asking. The preface to the main site includes a nuanced discussion about prices in the past:

“There is no single ‘correct’ measure, and economic historians use one or more different indices depending on the context of the question.”

When I first estimated Mr. Darcy’s income, this was precisely the problem I grappled with; simply translating wealth or incomes from the past to the present using a price index severely understates the meaning we’re trying to convey – i.e., how unfathomably rich this guy was. There is no doubt that Mr. Darcy was among the richest people in England at the time (his annual income some 400 times a normal worker’s salary), a well-respected and wealthy man of elevated rank. However, translating his wealth using a price index doesn’t even put him on the Times’ Rich List over the thousand wealthiest Britons today. Clearly, that won’t do.

Because we are much richer today in real terms, price indices alone do not capture the meaning we’re trying to communicate here. Higher real income – by definition – is a growth in incomes above the rise in prices. We therefore ought to use a more tangible comparison, for instance with contemporary prices of food or mansions or trips abroad; or else, using real income adjustments, such as GDP/capita or average earnings.

MeasuringWorth provides us with three other metrics over and above the misleading price-index adjustment:

Labour Earnings = £487,000
using growth in wages for the average worker, it reports how large your wage would have to be today to afford what Austen could afford on £631 in 1815. Obviously, quality adjustments and technological improvements make these comparisons somewhat silly (how many smartphones, air fares and microwaves could Austen buy?), but the figure at least takes real earnings into account.

Relative Income = £591,300
Like ‘Labour Earnings’, this adjustment builds on the insight above, but uses growth in real GDP/capita rather than wages. It more closely captures the “relative ‘prestige value’” that we’re getting at.

Both these attempt are what I tried to do for Mr. Darcy (Attempt #2 and #3) a few years ago.

Relative Output = £2,767,000
This one is more exciting because it captures the relationship to the overall economy. If I understand MeasuringWorth’s explanation correctly, this is the number that equates the share of British GDP today with what Austen’s wealth – £631 – would have represented in 1815.

Another metric I have been experimenting with is reporting the wealth number that would put somebody in the same position in the wealth distribution of our time. For example, it takes about £2,5m to qualify for the top-1% of British wealth (~$10m in the United States) distribution today. What amount of wealth did somebody need to join the top 1% in, say, 1815? If we could find out where Austen’s wealth of £631 (provided her annuities were her only assets) rank in the distribution of 1815, we can back out a modern-day equivalent. This measure avoids many of the technical problems above for how to properly adjust for a growing economy, and how to capture inventions in a price index – and it gets to what we’re really trying to convey: how wealthy was Austen in her time?

Alas, we really don’t have those numbers. We have to dive deep into the wealth inequality rabbit hole to even get estimates (through imputed earnings, capital stocks or probate records) – and even then the assumptions we need to make are as tricky and inexact as the ones we employ for wage series or prices above.

The bottom line is pretty boring: we don’t have a panacea. There is no “single correct measure”, and the right figure depends on the question you’re asking. A reasonable approach is to provide ranges, such as MeasuringWorth does.

But it’s hard to imagine the Financial Times writing “equivalent of between £45,000 and £2,767,000 at today’s prices”…

Economists, Economic History, and Theory

We can all come up with cringeworthy clichés for why history matters to society at large – as well as policy-makers and perhaps more infuriatingly, to hubris-prone economists:

And we could add the opposite position, where historical analysis is altogether irrelevant for our current ills, where This Time Is completely Different and where we naively disregard all that came before us.

My pushback to these positions is taken right out of Cameron & Neal’s A Concise Economic History of The World and is one of my most cherished intellectual guidelines. The warning appears early (p. 4) and mercilessly:

those who are ignorant of the past are not qualified to generalize about it.

We can also point to some more substantive reasons for why history matters to the present:

  • Discontinuities: by studying longer time period, in many different settings, we get more used to – and more comfortable with – the fact that institutions, routines, traditions and technologies that we take for granted may change. And do change. Sometimes slowly, sometimes frequently.
  • Selection: in combination with emphasizing history to understand the path dependence of development, delving down into economic history ought to strengthen our appreciation for chance and randomness. The history we observed was but one outcome of many that could have happened. The point is neatly captured in an obscure article of one of last year’s Nobel Prize laureates, Paul Romer: “the world as we know it is the result of a long string of chance outcomes.” Appropriately limiting this appreciation for randomness is Matt Ridley’s rejection of the Great Man Theory: a lot of historical innovations seems to have been inevitable (When Edison invented light bulbs, he had some two dozen rivals doing so independently).
  • Check On Hubris: history gives us ample examples of similar events to what we’re experiencing or contemplating in the present. As my Glasgow and Oxford professor Catherine Schenk once remarked in a conference I organized: “if this policy didn’t work in the past, what makes you think it’ll work this time?”

History isn’t only a check on policy-makers, but on ivory-tower economists as well. Browsing through Mattias Blum & Chris Colvin’s An Economist’s Guide to Economic Historypublished last year and has been making some waves since – I’m starting to see why this book is quickly becoming compulsory reading for economists. Describing the book, Colvin writes:

Economics is only as good as its ability to explain the economy. And the economy can only be understood by using economic theory to think about causal connections and underlying social processes. But theory that is untested is bunk. Economic history provides one way to test theory; it forms essential material to making good economic theory.

Fellow Notewriter Vincent Geloso, who has contributed a chapter to the book, described the task of the economic historian in similar terms:

Once the question is asked, the economic historian tries to answer which theory is relevant to the question asked; essentially, the economic historian is secular with respect to theory. The purpose of economic history is thus to find which theories matter the most to a question.

[and which theory] square[s] better with the observed facts.

Using history to debunk commonly held beliefs is a wonderful check on all kinds of hubris and one of my favorite pastimes. Its purpose is not merely to treat history as a laboratory for hypothesis testing, but to illustrate that multitudes of institutional settings may render moot certain relationships that we otherwise take for granted.

Delving down into the world of money and central banks, let me add two more observations supporting my Econ History case.

One chapter in Blum & Colvin’s book, ‘Money And Central Banking’ is written by Prof. John Turner at Queen’s in Belfast (whose writings – full disclosure – has had great influence on my own thinking). Focusing on past monetary disasters and the relationship between the sovereign and the banking system is crucial for economists, Turner writes:

We therefore have a responsibility to ensure that the next generation of economists has a “lest we forget” mentality towards the carnage that can be afflicted upon an economy as a result of monetary disorder.” (p. 69)

This squares off nicely with another brief article that I stumbled across today, by banking historian and LSE Emeritus Professor Charles Goodhart. Lamentably – or perhaps it ought to have been celebratory – Goodhart notes that no monetary regime lasts forever as central banks have for centuries, almost haphazardly, developed their various functions. The history of central banking, Goodhart notes,

can be divided into periods of consensus about the roles and functions of Central Banks, interspersed with periods of uncertainty, often following a crisis, during which Central Banks (CBs) are searching for a new consensus.”

He sketches the pendulum between consensus and uncertainty…goodhart monetary regime changes

…and suddenly the Great Monetary Experiment of today’s central banks seem much less novel!

Whatever happens to follow our current monetary regimes (and Inflation Targeting is due for an update), the student of economic history is superbly situated to make sense of it.

Mr. Darcy’s Ten Thousand a Year

On popular demand, I’m reviving a reoccurring theme of mine: teaching economic history through the lens of popular culture. Today: bonds, yields and 18th century English financial planning.

In what is probably my favourite piece ever written, I tried to estimate exactly how rich Mr. Darcy was – Mr. Darcy, of course, of Jane Austen’s classic novel Pride & Prejudice. I showed that whatever method you use to translate incomes to the present, all characters in Austen’s captivating story are astonishingly rich. But, as we well know today, there are large differences even among the superrich; compare Bernie Sanders (small-time millionaire) with George Lucas and Steven Spielberg (single-digit billionaires) or Jeff Bezos (wealthiest man alive).

Using Pride & Prejudice to illustrate some economic point is hardly unconventional (Piketty did this in his Capital in the Twenty-First Century), so let me similarly discuss 18th and 19th century British financial markets using the characters in this well-known tale.

The starting point is the following musing, courtesy of former Oxford Economist Martin Slater’s (2018: 52) The National Debt; how come “female characters in nineteenth-century novels always seem to have a suspiciously exact income of ‘so many pounds per year'”? Where does this money come from? Why is it so exact? And what’s the reason Piketty uses this particular literary example to illustrate the permanence and steady stream of income that capital somehow just throws off?

Consols and Financial Markets

Financial markets are truly awesome – not just in their impressive scope or potential devastation, but in the many different needs they simultaneously fulfil for many different people. Slater ably guides us through the confusing mishmash that is the 17th and 18th century English public finance, but what emerges by 1757, after Henry Pelham’s consolidation of government debt, is two main – and for our purposes, equivalent – securities: the Consolidated 3% Annuities (and the ‘Reduced annuities’), affectionately named ‘Consols’. These were permanent government bonds with annual interest payments of 3%. This means that they had no maturity date, i.e. the holder of the security could expect the government to keep paying 3% of the face value for all future (a Churchill-issued subsequent Consol was actually repaid and retired just a few years ago, after almost a century in service).

Two cool things happen. First, the “initial value” – the face value – of debt running in perpetuity becomes almost irrelevant, since all that matters for the issuer is the ability to maintain interest rate payments; there is no presumption of future repayment. Second, creditors – that is, holders of the Consols who receive the regular interest payments – may trade that asset on financial markets. Since the plethora of different debt assets were now condensed into a single, credible, identical and easily-identified asset, the market for 3% Consols in London developed into a very large and liquid market. With such ease of access and predictable and stable payoffs, the Consols became the instrument of saving for well-off families in Austen’s time.

A note on yields

The Consols, essentially a piece of paper with a face value of £100, entitled the owner to a perpetual stream of payments by the government, in this case 3% – or £3. Now, the actual price at which this paper could be sold in London fluctuated extensively depending on the conditions of the financial market and, most prominently in Austen’s lifetime, the Napoleonic wars. As the £3 annual pay was serviced by the British government, and financial strain during the war increased the risk for defaults (through a foreign invasion or British government itself), the price of Consols was chiefly reflecting the military success.

When the market price of a debt falls below its face value, the effective interest rate (the “yield”) that a prospective investor receives increases; paying £50 for a Consol with face value of £100 and a £3 perpetual interest payment, effectively earns the investor 6% interest instead of 3% (3/50 = 0.06). Since the Consols were the most dominant asset on the largest financial market in the world, their price became “the single most important asset price in the world economy” as Klovland (1994: 165) called it. Here’s the yield on Consols during Austen’s life:

JA, yield on 3%

It reached a low of 3.11% in 1792 (almost at par), and a high of 6.22% in 1798 (below £50) after the suspension of the gold standard.

The Bennets and the fortunes of handsome young men

The families of Pride & Prejudice made good use of this thriving financial market – not specifically for trading but for financial planning (others, such as British economist David Ricardo, and the banking families of Rothschild and Barings, made some of their fortune trading Consols).

In the novel, Mr. Bennet – the protagonist Lizzy’s father – has an income of £2,000 a year (again, see my 2016 piece for three different attempts at “translating” these sums into today’s money). It is not clear what his income comes from, but it’s a fair guess that it stems, like many other landed gentry of the time, from renting out farm lands belonging to the family home Longbourne. In addition, we know that Mrs. Bennet’s portion to the family home is a £5,000 contribution which is the sole inheritance the (five) Bennet daughters are entitled to.

Now, the way well-off families like the Bennets would make use of Consols was to ensure that non-inheriting children had at least some source of income after the passing of their father. The underlying concern in Pride & Prejudice, causing Mrs. Bennet to worry so about fortunate marriages for her daughters, is that the Bennet estate is entailed away to Mr. Collins – and with it the presumed rental income of £2,000 a year. That would leave the girls homeless, reduced to living off Mrs. Bennet’s inheritance of £5,000.

Austen began writing First Impressions (the initial title for Pride & Prejudice) in October 1796. During the decade leading up to this, the yield on Consols had been firmly within the interval 3.5-4.5%, hovering around 4% for years. It should thus not surprise us that Mrs. Bennet’s fortune of £5,000 presumably consisting of Consols, would have been purchased at around £75, predictably yielding the family an annual return of 4%. Indeed, the characters of Pride & Prejudice seem to be squarely set on 4% being the general norm. For instance, in a desperate attempt to enhance his already-inane proposal to Lizzy, Mr. Collins explicitly says:

“To fortune I am perfectly indifferent, and shall make no demand of that nature on your father, since I am well aware that it could not be complied with; and that one thousand pounds in the 4 per cents, which will not be yours till after your mother’s decease, is all that you may ever be entitled to.”

(Chapter 19, p. 133 in the 2009 HarperCollins edition)

Here we see the great use that Consols offered families like the Bennets. Once the Bennet parents pass away, the £5,000 of Consols could be divided equally among her children; Lizzy’s share would be a thousand pounds, which earns her an annual 4% interest return, or £40 (although maybe several year’s earnings for a regular worker, this was a rather small sum for such rich families – in contemplating Lizzy’s sister Lydia’s imprudent marriage, we learn that Mr. Bennet spent almost £100/year on Lydia’s purchases and pocket money alone). Being liquid financial assets, dividing up the Consols among children was very easy, and their steady income stream ensured that they would have at least some income. Bar Napoleonic conquest, the interest payment on the Consols would reliably show up year after year.

As for the handsome young men, Mr. Bingley’s case is easier than Mr. Darcy’s. We know that Bingley’s income is not agricultural, but investments from a fortune of almost  £100,000 inherited from his father, who had not yet acquired an estate. The fortune was “acquired by trade”, where (being from the North) cotton or shipping are prime candidates, but the slave trade is also a possibility. We also know that the ambiguity of his annual income (£4,000 or £5,000) lies well within the return from a fortune of that size invested in Consols. Indeed, for Bingley to hold that kind of fortune, earn that income and still not have an estate of his own, suggests that his financial wealth consists predominantly of Consols – perhaps complemented with some other stock (Bank of England or East India Company stock are plausible candidates). Clearly, new money.

Mr. Darcy, on the other hand, is plainly old money. And a lot of it. There are subtle hints in the novel that Pemberley has been in the Darcy family for generations. What we don’t know is precisely how his £10,000 a year is earned. When visiting Pemberley in Derbyshire with her aunt and uncle, Lizzy is told by the housekeeper that Mr. Darcy is such a generous and fair man: “ask any of his tenants”, she says, which indicates that Mr. Darcy, has a fair number of them – as one would expect from a sizeable estate like Pemberley. Now, what we don’t know is if the entirety of his £10,000 a year is reaped from rental income; it could be that some of his income is financial – or that either his financial or rental income is excluded from this rumoured number. Beyond a mention of his sister, Georgiana’s, fortune of £30,000 – which for convenience would likely be held in Consols – we know very little about the personal finances of Mr. Darcy.

The use and abuse of Consols

The financial market for government debt in the late-18th and early 19th century was not created with financial planning in mind, but by incremental improvements to previous government funding problems. The outcome, however, was a striking success for Britain, whose thriving financial market in no small part accounted for Britannia’s Century until WWI.

Moreover, as contemporary economists from Ricardo and John Stuart Mill to Malthus and Lauderdale observed, the recurring interest payments, funded by taxes, may have had quite large macroeconomic consequences. Taxing ‘productive’ investments and trade in order to fund ‘unproductive’ holders of government debt was, it was argued, harmful to the country – and in a time where government expenditures largely consisted of the military and debt maintenance, the impacts of funding the debt was of prime political interest.

Piketty’s use of Austen’s England (and Balzac’s France) was used for precisely the same distinction. Wealth, in Piketty’s view, perpetuates itself, and effortlessly earns its return (never mind the work, risk and selection issues involved). By continually paying the interest on its debt, the governments of Austen’s Britain financed the leisurly lifestyles of the rich, just as the “natural” return of the modern-day rich contribute and maintain today’s inequality.

The Consol was a revolutionary invention, but it is possible that it was not part of Mr. Darcy’s Ten Thousand a Year.

Not all GDP measurement errors are greater than zero!

Bryan Caplan is an optimist. He thinks that economists do many errors in estimating GDP (overall well-being). He is right in the sense that we are missing many dimensions of welfare improvements in the last half-century (see here, here and here). These errors in measurements lead us to hold incorrectly pessimistic views (such as those of Robert Gordon). However, Prof. Caplan seems to argue (I may be wrong) that all measurements problems and errors are greater than zero. In other words, they all cut in favor of omitting things. There are no reasons to believe this. Many measurement problems with GDP  data cut the other way – in favor of adding too much (so that the true figures are lower than the reported ones).

Here are two errors of importance (which are in no way exhaustive): household output and adjustments for household size.

Household Output

From the 1910s to the 1940s, married women began to enter moderately the workforce. This trickle became a deluge thereafter. National GDP statistics are really good at capturing the extra output they were hired to produce. However, national GDP statistics cannot net out the production that was foregone: household output.

A married woman in 1940 did produce something: child-rearing, house chores, cooking, allowing the husband to specialize in his work. That output had a value. Once offered the chance to work, married women thought the utility generated from producing “home outputs” was inferior to the utility generated from “market work”. However, the output that is measured is only related to market work. Women entered the labor force and everything they produced was considered a net addition to GDP. In reality, any economist worth his salt is aware that the true improvement in well-being is equal to the increased market output minus the forsaken house output. Thus, in a transition from a “male-labor force” to a “mixed labor force”, you are bound to overestimate output increases.

How big of an issue is this? Well, consider this paper from 1996 in Feminist Economics. In that paper, Barnet Wagman and Nancy Folbre calculate output in both the “household” and “market” sectors. They find that even very small changes in the relative size of these sectors alter growth rates by substantial margins. Another example, which I discussed in this blog post based on articles in the Review of Income and Wealth, is that when you make the adjustment over four decades of available Canadian data, you can find that one quarter of the increase in living standards is eliminated by the proper netting out of the value of non-market output. These are sizable measurement errors that cut in the opposite direction as the one hypothesized by prof. Caplan (and in favor of people like prof. Gordon).

Household Size

Changes in household sizes also create overestimation problems. Larger households have more economies of scale to exploit than smaller households so that an income of $10,000 per capita in a household of six members is superior in purchasing power than an income of $10,000 per capita in a single-person household. If, over time, you move from large households to small households, you will overestimate economic growth. In an article in the Scottish Journal of Political Economy, I showed that making adjustments for household sizes over time yields important changes in growth rates between 1890 and 2000. Notice, in the table below, that GDP per adult equivalent (i.e. GDP per capita adjusted for household size) is massively different than GDP per capita. Indeed, the adjusted growth rates are reduced by close to two-fifths of their original values over the 1945-2000 period and by a third over the 1890 to 2000 period. This is a massive overestimation of actual improvements in well-being.

HouseholdAdjust

A large overestimation

If you assemble these two factors together, I hazard a guess that growth rates would be roughly halved (there is some overlap between the two so that we cannot simply sum them up as errors to correct for – hence my “guess”). This is not negligible. True, there are things that we are not counting as Prof. Caplan notes. We ought to find a way to account for them. However, if they simply wash out the overestimation, the sum of errors may equal zero. If so, those who are pessimistic about the future (and recent past) of economic growth have a pretty sound case. Thus, I find myself unable to share Prof. Caplan’s optimism.

Asking questions about women in the academy

Doing the economist’s job well, Nobel Laureate Paul Romer once quipped, “means disagreeing openly when someone makes an assertion that seems wrong.”

Following this inspirational guideline of mine in the constrained, hostile, and fairly anti-intellectual environment that is Twitter sometimes goes astray. That the modern intellectual left is vicious we all know, even if it’s only through observing them from afar. Accidentally engaging with them over the last twenty-four hours provided some hands-on experience for which I’m not sure I’m grateful. Admittedly, most interactions on twitter loses all nuance and (un)intentionally inflammatory tweets spin off even more anger from the opposite tribe. However, this episode was still pretty interesting.

It started with Noah Smith’s shout-out for economic history. Instead of taking the win for our often neglected and ignored field, some twitterstorians objected to the small number of women scholars highlighted in Noah’s piece. Fair enough, Noah did neglect a number of top economic historians (many of them women) which any brief and incomprehensive overview of a field would do.

His omission raised a question I’ve been hooked on for a while: why are the authors of the most important publications in my subfields (financial history, banking history, central banking) almost exclusively male?

Maybe, I offered tongue-in-cheek in the exaggerated language of Twitter, because the contribution of women aren’t good enough…?

Being the twenty-first century – and Twitter – this obviously meant “women are inferior – he’s a heretic! GET HIM!”. And so it began: diversity is important in its own right; there are scholarly entry gates guarded by men; your judgment of what’s important is subjective, duped, and oppressive; what I happen to care about “is socially conditioned” and so cannot be trusted; indeed, there is no objectivity and all scholarly contribution are equally valuable.

Now, most of this is just standard postmodern relativism stuff that I couldn’t care less about (though, I am curious as to how it is that the acolytes of this religion came to their supreme knowledge of the world, given that all information and judgments are socially conditioned – the attentive reader recognises the revival of Historical Materialism here). But the “unequal” outcome is worthy of attention, and principally the issue of where to place the blame and to suggest remedies that might prove effective.

On a first-pass analysis we would ask about the sample. Is it really a reflection of gender oppression and sexist bias when the (top) outcome in a field does not conform to 50:50 gender ratios? Of course not. There are countless, perfectly reasonable explanations, from hangover from decades past (when that indeed was the case), the Greater Male Variability hypothesis, or that women – for whatever reason – have been disproportionately interested in some fields rather than others, leaving those others to be annoyingly male.

  • If we believe that revolutionising and top academic contributions have a long production line – meaning that today’s composition of academics is determined by the composition of bright students, say, 30-40 years ago – we should not be surprised that the top-5% (or 10% or whatever) of current academic output is predominantly male. Indeed, there have been many more of them, for longer periods of time: chances are they would have managed to produce the best work.
  • If we believe the Greater Male Variability hypothesis we can model even a perfectly unbiased and equal opportunity setting between men and women and still end up with the top contribution belonging to men. If higher-value research requires smarter people working harder, and both of those characteristics are distributed unequally between the sexes (as the Greater Male Variability hypothesis suggests), then it follows naturally that most top contributions would be men.
  • In an extension of the insight above, it may be the case that women – for entirely non-malevolent reasons – have interests that diverge from men’s (establishing precise reasons would be a task for psychology and evolutionary biology, for which I’m highly unqualified). Indeed, this is the entire foundation on which the value of diversity is argued: women (or other identity groups) have different enriching experiences, approach problems differently and can thus uncover research nobody thought to look at. If this is true, then why would we expect that superpower to be applied equally across all fields simultaneously? No, indeed, we’d expect to see some fields or some regions or some parts of society dominated by women before others, leaving other fields to be overwhelmingly male. Indeed, any society that values individual choice will unavoidably see differences in participation rates, academic outcomes and performance for precisely such individual-choice reasons.

Note that none of this excludes the possibility of spiteful sexist oppression, but it means judging academic participation on the basis of surveys responses or that only 2 out of 11 economic historians cited in an op-ed were women, may be premature judgments indeed.

On Robert Allen’s defense of the High-Wage Economy hypothesis

The high-wage economy thesis is a topic I have blogged about many times before as I think it is an important debate among economists and economic historians (see notably here and here, see also this contribution of mine to the Journal of Interdisciplinary History). For those unfamiliar with this thesis, here is a simple summary of the idea advanced by Robert Allen: high wages relative to capital units was a key force in the industrialization of Britain and thus it explains why the Industrial Revolution was British before if was anything else.

As I have explained in the aforementioned blog posts, I am unsure of where I stand regarding this idea. I tend to be skeptical, but I have stated the evidence needed to convince me of the opposite. In the past year or so, there has been an avalanche of articles on the topic including this article by Humphries and Weisdorf, a follow-up working paper by the same authors, another paper by Judy Stephenson and a working paper by Stephenson (bis). Today, Robert Allen replies to his critics in this working paper.

I find that some of the points are convincing, however I must take issue with a particular point that falls into my ballpark as Allen mentions my work on wages in France (the aforementioned article in Journal of Interdisciplinary History). In my research, I pointed out that Allen’s computations underestimated wages outside Paris. With the correct computations, the rest of France does not appear as poor relative to England as Allen suggests. Allen concedes this point but then goes to state the following:

Geloso (2018) has pointed out that the Strasbourg unskilled wage series for 1702-64 is low in comparison to that of comparable towns, and workers may have received food, which has not been taken into account.  This is a perceptive point, but its implications are limited. The most important use I make of the Strasbourg evidence is in calculating the ratio of the wage to the user cost of capital. If the Strasbourg wage in this calculation is raised to that of neighbouring towns, the wage-capital cost ratio does rise but only by a small degree. The reason for this somewhat surprising result is that the wage is also an argument in the formula for the user cost of capital–building workers have to build the machines and the mills that house them–so the denominator of the ratio increases as well as the numerator, although to a lesser extend.

This is a incorrect characterization of my argument. First, I did not state that wages in Strasbourg did not account for in-kind payment. I stated that in-kind payment was evidence that the wages did not pertain to Strasbourg! The wages from the primary sources were for a city some 70 km away from Strasbourg, they did not concern unskilled workers and they included large in-kind compensation. To correct for this problem, I compared agricultural wages in England with those around Strasbourg that had been collected by Auguste Hanauer. What I found was the the lowest wages in farming were equal to 74% of farm wages in Southern England (as opposed to 64% with Allen’s stated wages). While I did not report this in the article because I had doubts, it is worth pointing out that the high bound of farm wages in Strasbourg is above the level reported for Southern England (which acts a proxy for England – see table 2 in my paper). As Strasbourg is a proxy for living standards outside Paris, my finding suggests a much smaller gap in living standards. It also entails a much more important change in the cost of capital to labor (wages are in the range of 50% above those suggested by Allen and sometimes they are higher by more than 100% which would mean a halving of the relative cost of capital! These are not peanuts to be thrown on the sidewalk!

Second, I ought to point out the nature of my argument. I was not trying to prove/disprove the high-wage hypothesis. My point was much more modest. The mirror of the question as to why the industrial revolution was British is why it was not French. France had a large population offering large returns to scale (in both economic and political organizations) and an array of navigable rivers that facilitated internal trade. It also key pockets of Lancashire-like industrialization such as Normandy (for textile) and Mulhouse (the French Manchester). As such, it is an entirely reasonable endeavor to try to situate living standards in France relative to Britain. If France was massively poorer than England, then Allen has a greater likelihood of being correct. If it was closer to an equal footing (I do not believe that anyone places France above England in circa 1750), then Allen’s critics have a greater likelihood of being correct.* However, regardless of the answer, the data does not infirm/confirm the high-wage hypothesis. It merely situates relative likelihood. As I point out that wages were quite above those postulated by Allen, I am merely stating the extent of the reasonableness of being skeptical of the high-wage hypothesis.

Finally, it is worth pointing out that the work of Leonardo Ridolfi is absent from Allen’s reply. The latter’s work is very important as it echoes (in a much richer manner) my point that wages outside Paris were not as low as cited by Allen.**

*As I assume a greater equality of capital returns across both countries, the smaller the wage gap, the smaller the relative differences in capital/labor costs ratios.
** Ridolfi shows France had incomes equal to 64% of English incomes circa 1700. However, I am skeptical of this figure. This is because, while I trust the index produced by Ridolfi, I am unconvinced about the benchmark year to convert the index into international dollars.

On “strawmanning” some people and inequality

For some years now, I have been interested in the topic of inequality. One of the angles that I have pursued is a purely empirical one in which I attempt to improvement measurements. This angle has yielded two papers (one of which is still in progress while the other is still in want of a home) that reconsider the shape of the U-curve of income inequality in the United States since circa 1900.

The other angle that I have pursued is more theoretical and is a spawn of the work of Gordon Tullock on income redistribution. That line of research makes a simple point: there are some inequalities that are, in normative terms, worrisome while others are not. The income inequality stemming from the career choices of a benedictine monk and a hedge fund banker are not worrisome. The income inequality stemming from being a prisoner of one’s birth or from rent-seekers shaping rules in their favor is worrisome.  Moreover, some interventions meant to remedy inequalities might actually make things worse in the long-run (some articles even find that taxing income for the sake of redistribution may increase inequality if certain conditions are present – see here).  I have two articles on this (one forthcoming, the other already published) and a paper still in progress (with Rosolino Candela), but they are merely an extension of the aforementioned Gordon Tullock and some other economists like Randall Holcombe, William Watson and Vito Tanzi. After all, the point that a “first, do no harm” policy to inequality might be more productive is not novel (all that it needs is a deep exploration and a robust exposition).

Notice that there is an implicit assumption in this line of research: inequality is a topic worth studying. This is why I am annoyed by statements like those that Gabriel Zucman made to ProMarket. When asked if he was getting pushback for his research on inequality (which is novel and very important), Zucman answers the following:

Of course, yes. I get pushback, let’s say not as much on the substance oftentimes as on the approach. Some people in economics feel that economics should be only about efficiency, and that talking about distributional issues and inequality is not what economists should be doing, that it’s something that politicians should be doing.

This is “strawmanning“. There is no economist who thinks inequality is not a worthwhile topic. Literally none. True, economists may have waned in their interest towards the topic for some years but it never became a secondary topic. Major articles were published in major journals throughout the 1990s (which is often identified as a low point in the literature) – most of them groundbreaking enough to propel the topic forward a mere decade later. This should not be surprising given the heavy ideological and normative ramifications of studying inequality. The topic is so important to all social sciences that no one disregards it. As such, who are these “some people” that Zucman alludes too?

I assume that “some people” are strawmen substitutes for those who, while agreeing that inequality is an important topic, disagree with the policy prescriptions and the normative implications that Zucman draws from his work. The group most “hostile” to the arguments of Zucman (and others such as Piketty, Saez, Atkinson and Stiglitz) is the one that stems from the public choice tradition. Yet, economists in the public-choice tradition probably give distributional issues a more central role in their research than Zucman does. They care about institutional arrangements and the rules of the game in determining outcomes. The very concept of rent-seeking, so essential to public choice theory, relates to how distributional coalitions can emerge to shape the rules of the game in a way that redistribute wealth from X to Y in ways that are socially counterproductive. As such, rent-seeking is essentially a concept that relates to distributional issues in a way that is intimately related to efficiency.

The argument by Zucman to bolster his own claim is one of the reason why I am cynical towards the times we live in. It denotes a certain tribalism that demonizes the “other side” in order to avoid engaging in them. That tribalism, I believe (but I may be wrong), is more prevalent than in the not-so-distant past. Strawmanning only makes the problem worse.

On Household Size and Economic Convergence

A few days ago, one of my papers was accepted for publication at the Scottish Journal of Political Economy (working paper version here). Co-authored with Vadim Kufenko and Klaus Prettner, this paper makes a simple point which I think should be heeded by economists: household size matter. To be fair, economists are aware of this when they study inequality or poverty. After all, the point is pretty straightforward: larger households command economies of scale so that each dollar goes further than in smaller households. As such, adjustments are necessary to make households comparable.

Yet, economists seem to forget it when times come to consider paths of economic growth and convergence across countries. In the paper, we try to remedy this flaw. We do so because there was a wide heterogeneity of household size throughout history – even within more homogeneous clubs such as the countries composing the OECD.  If we admit, as the economists who study poverty and inequality do, that income per person adjusted for household size is preferable to income per person, then we must recognize that our figures of income per capita will misstate the actual differences between countries. In addition, if households grew homogeneously smaller over a long period of time, figures of income per capita will overstate the actual improvements in living standards. As such, we argue there is value in modifying the figures to reflect changing household sizes.

For OECD countries, we find that the adjusted income figures increased a third less than the unadjusted per capita figures (see table below). This suggests a more modest growth trend. In addition, we also find that up to the structural break in variations between countries (NDLR: divergence between OECD countries increased to around 1950) there was more divergence with the adjusted figures than with the unadjusted figures (see figure below). We also find that since the break point, there has been less convergence than previously estimated.

While the paper is presented as a note, the point is simple and suggests that those who study convergence between regions or countries should consider the role of demography more carefully in their work.

Fogel on economics and ideology

Many, upon reading the conclusions of economists, believe that economics has an ideological bent. I often respond that this is not the case. True, the “window” of political opinions in economics is narrower but that is largely because the adhesion of economists to methodological individualism precludes certain ideological views that rest on holistic approaches or concepts. However, when you consider more complex situations than “party affiliation”, you will find economists all over the place. They will often cross ideological lines or even have a foot in two antagonistic camps.

Recently, I was reading Robert Fogel’s lectures on the “Slavery debates” which retells the intellectual history of American slavery from U.B. Phillips to … well … Fogel himself. One must remember that Fogel was, and remained from what I can tell, a quite strongly left-leaning economist for most of his life (see here). As such, it is hard to consider Fogel as an ideologue preaching for free market economics. Yet, in the lectures, Fogel (p.19) makes a point that supports the contention that I often make regarding economists and ideology that I believe must be shared:

The ability to view Phillips (NDLR: the dominant interpretation of slavery pre-1960) in a new light was facilitated by the sudden intrusion of a large corps of economists into the slavery debates during the 1960s. This intrusion was welcomed by neither the defenders of the Phillips tradition nor the neoabolitionist school led by Stampp (NDLR: Kenneth Stampp, author of The Peculiar Institution). The cliometricians, as they were called, refused to be bound by the established rules of engagement, and they blithely crossed ideological wires in a manner that perplexed and exasperated traditional historians on both sides of the ideological divide.

Given that the source of this quotation is Fogel, I admit that I am particularly fond of this passage. Maybe the distrust towards economists is because economists can be both friend and foes to established interlocutors in a given discussion.

Divergence and Convergence within Italy

Two years, I wrote a post on this blog on the process of regional convergence in Italy. In that post, I made the observation that it seems that, economically, Italy was as fragmented at the time of the unification as it is today which made it an oddity in terms of regional convergence. To make that claim, I used this table of relatively sparsed out observations produced by Emanuele Felice: which was published in the Economic History Reviewitaliangdp

 

 

 

 

 

 

 

 

 

As one can see, there is a pronounced “lack” of integration for the Italy in terms of living standards. This is reinforced by a more “continuous” set of estimates produced, again, by Emanuele Felice (this time, its a working paper of the Bank of Italy) that now include the 1870s and go to 2011 (as opposed to 2001). This is the result, which I find fascinating. The first graph shows GDP per capita – for which there is divergence to 1951 and then a mild convergence thereafter but still well above the levels at the time of unification.  More fascinating is the fact that productivity is at its most integrated since unification (2nd figure) suggesting a divergence in levels of labor activity (3rd figure). In these three graphs, you have a neat summary of Italian labor markets since 1870.

The great global trend for the equality of well-being since 1900

Some years ago, I read The Improving State of the World: Why We’re Living Longer, Healthier, More Comfortable Lives on a Cleaner Planet by Indur Goklany. It was my first exposition to the claim that, globally, there has been a long-trend in the equality of well-being. The observation made by Goklany which had a dramatic effect on me was that many countries who were, at the time of his writing, as rich (incomes per capita) as Britain in 1850 had life expectancy and infant mortality levels well superior to 1850 Britain. Ever since, I accumulated the statistics on that regard and I often tell my students that when comes the time to “dispell” myths regarding the improvement in living standards since circa 1800 (note: people are generally unable to properly grasp the actual improvement in living standards).

Some years after, I discovered the work of Leandro Prados de la Escosura who is a cliometrician who (I think I told him that when I met him) influenced me deeply in my work regarding the measurement of living standards and who wrote this paper which I will discuss here.  His paper, and his work in general, shows that globally the inequality in incomes has faltered since the 1970s.  That is largely the result of the economic rise of India and China (the world’s two largest antipoverty programs). Figure1Leandro

However, when extending his measurements to include life expectancy and schooling in order to capture “human development” (the idea that development is not only about incomes but the ability to exercise agency – i.e. the acquisition of positive liberty), the collapse in “human development” inequality (i.e. well-being) precedes by many decades the reduction in global income inequality. Indeed, the collapse started around 1900, not 1970!

Figure2LEandro.png

In reading Leandro’s paper, I remembered the work of Goklany which had sowed the seeds of this idea in my idea. Nearly a decade after reading Goklany’s work well after I fully accepted this fact as valid, I remain stunned by its implications. You should too.

On the rift between economics and everything else

The line is often heard: economists are “scientific imperialists” (i.e. they seek to invade other fields of social science) jerks. All they try to do is “fit everything inside the model”. I have this derisive sneer at economists very often. I have also heard economists say “who cares, they’re a bunch of historians” (this is the one I hear most often given my particular field of research, but I have heard variations involving sociologists and anthropologists).

To be fair, I never noticed the size rift. For years now, I have been waltzing between economics and history (and tried my hand at journalism for some time) which meant that I was waltzing between economic theory and a lot of other fields. The department I was a part of at the London School of Economics was a rich set of quantitative and qualitative folks who mixed history of ideas, economics, economic history and social history. To top it all, I managed to find myself generally in the company of attorneys and legal scholars (don’t ask why, it still eludes me). It was hard to feel a big rift in that environment. I knew there was a rift. I just never realized how big it was until a year ago (more or less).

There is, however, something that annoys me: the contempt appears to be self-reinforcing.  Elsewhere on this blog (here and here) (and in a forthcoming book chapter in a textbook on how to do economic history), I have explained that economists have often ventured into certain topics with a lack of care for details. True, there must be some abstraction of details (not all details are useful), but there is an optimal quantity of details. And our knowledge grows, the quantity of details necessary to answering each question (because the scientific margin is increasingly specialized) should grow. And so should the number (and depth) of nuances we make to answer a question.  There is a tendency among economists to treat a question outside the usual realm of economics and ignore the existing literature (thus either rushing through an open door or stepping in a minefield without knowing it).  The universe is collapsed into the model and, even when it yields valuable insights, other (non-econs) contributors are ignored.  That’s when the non-econs counter that economists are arrogant and that they try to force everything into a mold rather than change the mold when it does not apply. However, the reply has often been to ignore the economists or criticize strawmen versions of their argument. Perceived as contemptuous, the economists feel that they can safely ignore all others.

The problem is that this is a reinforcing loop: a) the economists are arrogant; b) non-economists respond by dismissing the economists and ridiculing their assumptions; c) the economists get more arrogant. The cycle persists. I struggle to see how to break this cycle, but I see value in breaking it. Elsewhere, I have made such a case when I reviewed a book (towards which I was hostile) on Canadian economic history. Here is what I said for the sake of showcasing the value of breaking the vicious circle of ignoring both sides:

These scholars (those who have been ignored by non-economists) could have easily derived the same takeaways as Sweeny. Individuals can and do engage in rent-seeking, which economists define as the process through which unearned gains are obtained by manipulating the political and social environment. This could be observed in attempts to shape narratives in the public discourse. According primacy to the biases of sources is a recognition that there can be rent-seeking in the form of actors seeking to generate a narrative to reinforce a particular institutional arrangement and allow it to survive. This explanation is well in line with neoclassical economics.

This point is crucial. It shows a failing on both sides of the debate. Economists and historians favorable to “rational choice” have failed to engage scholars like Sweeny. Often, they have been openly contemptuous. The literature has evolved in separate circles where researchers only speak to their fellow circle members. This has resulted in an inability to identify the mutual gains of exchange. The insights and meticulous treatments of sources by scholars like Sweeny are informative for those economists who consider rational choice as if the choosers were humans, with all their flaws and limitations, rather than mechanistic utility-maximizing machines with perfect foresight (which is a strawman often employed to deride the use of economics in historical debates) . In reverse, the rich insights provided by rational choice theorists could guide historians in elucidating complex social interactions with a parsimony of assumptions. Without interaction, both groups loose and resolutions remain elusive.

See, as a guy who likes economics, I think that trade is pretty great. More importantly, I think that trade between heterogeneous groups (or different individuals) is even greater because it allows for specialization that increases the value (and quantity) of outputs.  I see the benefits of trade here, so why is this “circle of contempt” perpetuating so relentlessly?

Can’t we just all pick the 100$ bill on the sidewalk?
