In Defense of Not Having a Clue

Timely, both in our post-truth world and for my current thinking, Bobby Duffy of the British polling company IPSOS Mori recently released The Perils of Perception, stealing the subtitle I have (humbly enough) planned for years: Why We’re Wrong About Nearly Everything. Duffy and IPSOS’s Perils of Perception surveys are hardly unknown for an informed audience, but the book’s collection and succint summary of the psychological literature behind our astonishingly uninformed opinions, nevertheless provide much food for thought.

Producing reactions of chuckles, indignation, anger, and unseeming self-indulgent pride, Duffy takes me on a journey of the sometimes unbelievably large divergence between the state of the world and our polled beliefs about the world. And we’re not primarily talking about unobservable things like “values” here; we’re almost always talking about objective, uncontroversial measures of things we keep pretty good track of: wealth inequality, share of immigrants in society, medically defined obesity, number of Facebook accounts, murder and unemployment rates. On subject after subject, people guess the most outlandish things: almost 80% of Britons believed that the number of deaths from terrorist attacks between 2002 and 2016 were more or about the same as 1985-2000, when the actual number was a reduction of 81% (p. 131); Argentinians and Brazilians seem to believe that roughly a third and a quarter of their population, respectivelly, are foreign-born, when the actual numbers are low single-digits (p. 97); American and British men believe that American and British women aged 18-29 have had sex as many as 23 times in the last month, when the real (admittedly self-reported) number is something like 5 times (p. 57).

We can keep adding astonishing misperceptions all day: Americans believe that more than every third person aged 25-34 live with their parents (reality: 12%), but Britons are even worse, guessing almost half (43%) of this age bracket, when reality is something like 14%; Australians on average believe that 32% of their population has diabetes (reality more like 5%) and Germans (31% vs 7%), Italians (35% vs 5%), Indians (47% vs 9%) and Britons (27% vs 5%) are similarly mistaken.

The most fascinating cognitive misconception is Britain’s infected relationship with inequality. Admittedly a confusing topic, where even top-economists get their statistical analyses wrong, inequality makes more than just the British public go bananas. When asked how large a share of British household wealth is owned by the top-1% (p. 90), Britons on average answered 59% when the reality is 23% (with French and Australian respondents similarly deluded: 56% against 23% for France and 54% against 21% for Australia). The follow-up question is even more remarkable: asked what the distribution should be, the average response is in the low-20s, which, for most European countries, is where it actually is. In France, ironically enough given its current tax riots, the respondents’ reported ideal household wealth proportion owned by the top-1% is higher than it already is (27% vs 23%). Rather than favoring upward redistribution, Duffy draws the correct conclusion:

“we need to know what people think the current situation is before we ask them what they think it should be […] not knowing how wrong we are about realities can lead us to very wrong conclusions about what we should do.” (p. 93)

Another one of my favorite results is the guesses for how prevalent teen pregnancies are in various countries. All of the 37 listed countries (p. 60) report numbers around less than 3% (except South Africa and noticeable Latin American and South-East Asian outliers at 4-6%), but respondents on average quote absolutely insane numbers: Brazil (48%), South Africa (44%) Japan (27%), US (24%), UK (19%).

Note that there are many ways to trick people in surveys and report statistics unfaithfully and if you don’t believe my or Duffy’s account of the IPSOS data, go figure it out for yourself. Regardless, is the take-away lesson from the imagine presented really that people are monumentally stupid? Ignorant in the literal sense of the world (“uninstructed, untututored, untaught”), or even worse than ignorant, having systematically and unidirectionally mistaken ideas about the world?

Let me confess to one very ironic reaction while reading the book, before arguing that it’s really not the correct conclusion.

Throughout reading Duffy’s entertaining work, learning about one extraordinarily silly response after another, the purring of my self-indulgent pride and anger at others’ stupidity gradually increased. Glad that, if nothing else, that I’m not as stupid as these people (and I’m not: I consistently do fairly well on most questions – at least for the countries I have some insight into: Sweden, UK, USA, Australia) all I wanna do is slap them in the face with the truth, in a reaction not unlike the fact-checking initiatives and fact-providing journalists, editorial pages, magazines, and pundits after the Trump and Brexit votes. As intuitively seems the case when people neither grasp nor have access to basic information – objective, undeniable facts, if you wish – a solution might be to bash them in the head or shower them with avalanches of data. Mixed metaphors aside, couldn’t we simply provide what seems to be rather statistically challenged and uninformed people with some extra data, force them to read, watch, and learn – hoping that in the process they will update their beliefs?

Frustratingly enough, the very same research that indicate’s peoples inability to understand reality also suggests that attempts of presenting them with contrary evidence run into what psychologists have aptly named ‘The Backfire Effect’. Like all force-feeding, forcing facts down the throats of factually resistent ignoramuses makes them double down on their convictions. My desire to cure them of their systematic ignorance is more likely to see them enshrine their erroneous beliefs further.

Then I realize my mistake: this is my field. Or at least a core interest of the field that is my professional career. It would be strange if I didn’t have a fairly informed idea about what I spend most waking hours studying. But the people polled by IPSOS are not economists, statisticians or data-savvy political scientists – a tenth of them can’t even do elementary percent (p. 74) – they’re regular blokes and gals whose interest, knowledge and brainpower is focused on quite different things. If IPSOS had polled me on Premier League results, NBA records, chords or tunes in well-known music, chemical components of a regular pen or even how to effectively iron my shirt, my responses would be equally dumbfunded.

Now, here’s the difference and why it matters: the respondents of the above data are routinely required to have an opinion on things they evidently know less-than-nothing about. I’m not. They’re asked to vote for a government, assess its policies, form a political opinion based on what they (mis)perceive the world to be, make decisions on their pension plans or daily purchases. And, quite a lot of them are poorly equipped to do that.

Conversely, I’m poorly equipped to repair literally anything, work a machine, run a home or apply my clumsy hands to any kind of creative or artful endeavour. Luckily for me, the world rarely requires me to. Division of Labor works.

What’s so hard with accepting absence of knowledge? I literally know nothing about God’s plans, how my screen is lit up, my car propels me forward or where to get food at 2 a.m. in Shanghai. What’s so wrong with extending the respectable position of “I don’t have a clue” to areas where you’re habitually expected to have a clue (politics, philosophy, virtues of immigration, economics)?

Note that this is not a value judgment that the knowledge and understanding of some fields are more important than others, but a charge against the societal institutions that (unnaturally) forces us to. Why do I need a position on immigration? Why am I required (or “entitled”, if you believe it’s a useful duty) to select a government, passing laws and dealing with questions I’m thoroughly unequipped to answer? Why ought I have a halfway reasonable idea about what team is likely to win next year’s Superbowl, Eurovision, or Miss USA?

Books like Duffy’s (Or Rosling’s, or Norberg‘s or Pinkers) are important, educational and entertaining to-a-t for someone like me. But we should remember that the implicit premium they place on certain kinds of knowledge (statistics and numerical memory, economics, history) are useful in very selected areas of life – and rightly so. I have no knowledge of art, literature, construction, sports, chemistry or aptness to repair or make a single thing. Why should I have?

Similarly, there ought to be no reason for the Average Joe to know the extent of diabetes, immigration or wealth inequality in his country.

Libertarianism and the shutdown

Yesterday, Paul Krugman published a deceptive, sloppy, and self-contradictory opinion article in the New York Times entitled “Trump’s Big Libertarian Experiment.” The premise: the shutdown delivers what all libertarians want, and the shutdown (this is strongly implied) demonstrates just how silly libertarians are.

This is nonsense. First off, Trump is decidedly not a libertarian. Second, government shutdowns have occurred for decades–are all of these “libertarian” experiments? Finally, no libertarians that I’m aware of have ever favored mercurial spending freezes that sweep the rug out from under people who’ve come to rely on government programs. Principled reform is a bit different from abrupt financial lurches.

The disruption and harm caused by sudden spending jolts have no bearing on whether a libertarian society could work or not. Krugman points out that businesspeople are already enraged that the Small Business Administration has ceased issuing loans, an organization that many libertarians have claimed is unnecessary. Of course they’re angry–they expected something that suddenly has ceased. That has absolutely nothing to do with whether the SBA is necessary; it just demonstrates that people get ticked off when their expectations are suddenly dashed. The shutdown proves nothing about whether the private market could ultimately supply any benefits offered by the SBA.

He also says that work at the FDA has dwindled. Routine inspections have ceased. He has zero evidence that this has caused even an iota of harm to anyone, but the implication is clear: we’ll all be confined to the toilets soon as E. coli swamps the country. He marshals no evidence to confront whether state regulators can adequately fill this role, or whether tort law and market forces can suffice.

Libertarians envision a society in which many roles currently served by government can find contractual and common-law counterparts (or not, if it turns out no one wants the service). Libertarians certainly don’t believe in blasting holes in long-standing social structures without warning, without forethought, or without transition.

Ironically, to the extent we do confront Krugman’s silly claims, it appears that the shutdown’s impact has been minimal despite huge numbers of furloughed employees. The New York Times, aside from Krugman’s disposable rhetoric, also published a comparison of the number of furloughed employees (800,000 by their estimation) to private industries. The number of furloughed employees, for example, exceeds twice the number of people employed by Target. I don’t think this tells us what the New York Times thinks it tells us. These stats beg the question as to whether these positions are necessary at all. That said, any negative impact from the shutdown that actually does exist–aside from the furloughed workers losing money–should be attributed to social and economic disruption resulting from spending turbulence, not to the actual necessity of the government programs affected.

Why Christmas materialism is awesome

It has always struck me as odd that capitalism’s usual defenders abandon it when commercialism seems to be on its best behavior. Every year, we religionists love to rail against Christmas materialism. What a terrible curse–people in the marketplace thinking of others’ interests and needs for once.  All the efficiency of the market PLUS good will toward men–why are we complaining, again?

Yet we do. Without fail, twitter feeds and chapel lecterns ring with invectives against Christmas commercialism. The warning voice, though, never seems to strike with precision. The concern seems to be that a focus on stuff gives rise to an idolatrous dethroning of deity.  This religious criticism appears to mimic the secular and progressive criticism that commerce somehow defiles us and strips us of virtues like compassion or solidarity.

I don’t buy either of these criticisms, largely for the same reasons: commerce brings people together, builds trust, and fosters goodwill. These benefits are in addition to the efficiencies that market advocates typically emphasize. And these three aspects of commercial exchange are in special abundance during Christmas.

Perhaps the materialism complaint stumbles at the outset by focusing on the largely mythical human calculator that predominates in economic theory–the man focused only on maximization of personal utility. That portraiture does not explain the fact that so much commerce occurs on behalf of someone else–a reality underscored and amplified during holiday shopping. Thus, Christmas supports Amartya Sen’s critique of the rational-man theory: “The purely economic man is indeed close to being a social moron.” He’s the one who gives you lotion samples and leftover hotel shampoo in your stocking. But most of us don’t do that. Instead, the market provides a forum for us to express and cultivate virtue. As Deirdre McCloskey says, “In other words, it’s not the case that market capitalism requires or generates loveless people. More like the contrary. Markets and even the much-maligned corporation encourage friendships wider and deeper than the atomism of a full-blown socialist regime.” I think a simple test proves this point. If you walk about a shopping mall during the Christmas holiday (setting aside for a moment your inner misanthrope), how are people behaving? By and large, there is an overpowering sense of goodwill among people engaged in (shudder) holiday materialism. I’d say this is mostly true at any time of year, but we may as well notice this phenomenon when it stands at its apex.

Beyond just the goodwill generated by the act of commerce, the materialism critique seems to ignore the very purpose of the materialistic behavior being condemned. Shouldn’t we celebrate this key example of how commercialism can enhance friendship through gift-giving? If you’re a religious capitalist, what is there not to like here?

A friend pointed out recently that Christmas giving seems fruitless, since the value-for-value gift exchanges offset each other. He concluded we may as well just keep our money. From an efficiency standpoint, it does seem strange to engage in a transaction cost without any expectation that you’ll achieve a pareto-efficient state of affairs. Samuelsonian economics alone can’t really explain why people engage in this ritual. That’s probably because the ritual is not purely economic. It’s about connection, relationship, and opportunity to think beyond ourselves. In other words, at bottom, it really is not about materialism in the shallow, desiccated sense that these Christmas puritans rail against. Commerce can be about compassion and camaraderie–not just self-interested calculation (though there’s nothing wrong with that either).

I don’t think the Babe of Bethlehem would disagree. After all, Jesus, while no aristocrat, was not a severe ascetic by any means–somewhat of a contrast to his cousin, John the Baptist. Perhaps the most poignant example of his view toward extravagant gift-giving occurs when a woman anoints him with an extremely valuable ointment. His disciples complained of the waste, griping that the ointment should’ve been sold and the proceeds given to the poor. Jesus defended her: “Let her alone; why trouble ye her? She hath wrought a good work on me.” In other words, a materialistic act can still be a virtuous one. In fact, I’d go as far as to say that the vast majority of them are. We need, after all, an earthly vehicle by which to exercise heavenly virtue. The market is well-suited for that role. God can be in a market–he’s that good.

Of course, a post about Christmas and materialism must make obligatory mention of Ebenezer Scrooge. Dickens was no fan of capitalism, but his reformed villain ironically proves a point about Christmas materialism: it’s the lack of virtue in the individual operating in the market, not the market itself, that desiccates the soul. So perhaps I can end with a simple “Scrooge” test: is Scrooge the guy standing back and pointing the finger, or is Scrooge the person that the finger aims at–the mom who braves the crowded mall to plop her kids on Santa’s lap and wraps gifts until 3:00 AM in the morning?

Forging ahead, falling behind and fighting back: British economic growth from the industrial revolution to the financial crisis

Nick Crafts can be viewed as the doyen of British economic history. His major publications date back to the 1970s – a favorite of mine is this piece from 1977 on the role played by chance in determining whether the Industrial Revolution would occur in England or France.  He is also the joint author of the Crafts-Harley interpretation of the Industrial Revolution.  But, perhaps because the majority of his research focuses on British economic history, he remains highly underrated outside of the UK.  His new book Forging ahead, falling behind and fighting back: British economic growth from the industrial revolution to the financial crisis summarizes much of his research.

I’ve reviewed it for the Economic History Review. But given the whims of academic publishing, it may be a long time until my review appears in print so I’ve decided to post a preview of my draft below.

**************************

Why was Britain the first industrial nation and the workshop of the world? Why was it eventually caught up and overtaken? Why once it had fallen behind the United States, did it fall further behind its European rivals in the Post-War period? And how did it recover its relative position in the 1980s and 1990s? All these questions are addressed in Nicholas Crafts’s slim new book.

In Forging ahead, falling behind and fighting back, Crafts provides a macroeconomic perspective on the British economy from 1750 to today. The word macro is advisory. Crafts surveys the British economy from 1000 feet, through the lens of growth theory and growth accounting. The upside of this approach is that he delivers a lot of insight in a small number of pages. Readers looking for discussions of individual inventors, innovations, politicians, or discussion of specific policy decisions can look elsewhere.

The first part of the book provides an overview of the Crafts-Harley view of the British Industrial Revolution. This view emphasizes the limited scope of economic change in the early 19th century. On the eve of the Industrial Revolution, the British economy already had a comparatively modern structure, with many individuals working outside agriculture. Growth between 1770 and 1850 was highly reliant on a few key sectors and TFP growth was modest (0.4% a year). Most workers remained employed in traditional sectors of the economy. It took until the second half of the 19th century for the benefits of steam, the general purpose technology of the age, to fully diffuse through the economy. Nonetheless, from a long-run perspective, the achievements of this period, a small but sustained increases in per capita GDP despite rapid population growth, were indeed revolutionary.

An important theme of the book is institutional path dependency. Characteristics of Britain’s early position as an industrial leader continued to shape its political economy down to the end of the 20th century. Crafts mentions two interesting instances of this. First, Britain’s precocious reliance on food imports from the early 19th century onwards left a legacy that was favorable of free trade. Elsewhere in the world democratization in the late 19th century often led to protectionism, but in Britain, it solidified support for free trade because, after the expansion of the franchise, the median voter was an urban worker dependent on cheap imported bread. Second, industrial relationships were shaped the nature of the economy in the 19th century. Britain thus inherited a strong tradition of craft unions that would have consequences in conflicts between labor and capital in the 20th century.

The second part of the book considers the late Victorian, Edwardian, and inter-war periods. It was in the late 19th century that the United States overtook Britain. A venerable scholarship has identified this period as one of economic failure. Crafts, however, largely follows McCloskey in exonerating Edwardian Britain from the charge of economic failure. The presence of fierce competition limited managerial inefficiencies in most areas of the economy; though there were notable failures in sectors where competition was limited such as the railways. The main policies errors in this area were thus ones of omission rather than commission: more could have been done to invest in R&D and support basic science – an area where the US certainly invested in more than the UK.

The seeds of failure, for Crafts, were sown in the interwar period. Traditionally these years have been viewed relatively favorably by economic historians, as the 1930s saw a shift away from Industrial Revolution patterns of economic activity and investment in new sectors. However, in a comparative light, TFP growth in the interwar period was significantly slower than in the US. The new industries did not establish a strong export position. This period also saw the establishment of a managed economy, in which policymakers acceded to a marked decline in market competition. Protectionism and cartelization kept profits high but at a cost of long-run productivity growth that would only be fully revealed in the post-war period.

Most economic historians view the postwar period through the lens of Les Trente Glorieuses. But in Britain, it has long been recognized that this was an era of missed opportunities. Simple growth accounting suggests that Britain underperformed relative to its European peers. Thus though the British economy grew faster in these years than in any other period; it is in this period that Britain’s relative failure should be located.

Crafts examines this failure using insights from the literature on “varieties of capitalism” which contrasts coordinated market economies like West Germany with liberal market economies like the United States or Britain. In the favorable conditions of postwar recovery and growth, coordinated market economies saw labor cooperate with capital enabling both high investment and wage restraint. Britain, however, lacked the corporatist trade unions of France or West Germany. As a legacy of the Industrial Revolution, it inherited a diverse set of overlapping craft unions which could not internalize the benefits of wage restraint and often opposed new technologies or managerial techniques. Britain functioned as a dysfunctional liberal market economy, one that became increasingly sclerotic as the 1960s passed into the 1970s.

An important insight I got from this book is that government failure and market failure are not independent.  Examples of government failure from the postwar period are plentiful. Industrial policy was meant to “pick winners.” But “it was losers like Ross Royce, British Leyland ad Alfred Herbert who picked Minsters” (p. 91). Market power became increasingly concentrated. Approximately 1/3 of the British economy in the 1950s was cartelized and 3/4 saw some level of price fixing. Britain’s exclusion from the EEC until the 1970s meant that protective barriers were high, enabling inefficient firms and managerial practices to survive. High marginal rates of taxation and weak corporate governance encouraged managers to take their salary in the form of in-kind benefits, and deterred innovation. Labor relations became increasingly hostile as the external economic environment worsened following the end of Bretton Woods.

Britain recovered its relative economic position after 1979 through radical economic reforms and a dramatic shift in policy objectives. Though of course, the Thatcher period saw numerous missteps and policy blunders, what Crafts argues was most important was that there was an increase in product market competition, a reduction in market distortions, and a reduction of trade union power, factors provided the space that enabled the British economy to benefit from the ICT revolution in the 1990s.

Rarely does one wish a book to be longer. But this is the case with Forging Ahead, Falling Behind, and Fighting Back. In particular, while a short and sharp overview of the Industrial Revolution is entirely appropriate, given the number of pages written on this topic in recent years, the last part of the book does need extra pages; the argument here is too brief and requires more evidence and substantive argumentation. One wishes, for instance, that the theme of institutional path dependency was developed in more detail. Despite this, Forging Ahead, Falling Behind, and Fighting Back is a notable achievement. It provides a masterly survey of British economy history tied together by insights from economic theory.

Eye Candy: The HDI of BRICS

Phew, that’s a lot of acronyms. But this is a great map:

NOL map BRICS subunits

Orange and yellow is bad, green and blue is good. HDI stands for “Human Development Index,” which is a measurement that’s not nearly as good, in my opinion, for understanding how wealthy and happy a population is. Nevertheless, HDI is still one of the better measurements (Top 5, again in my opinion) out there. Here’s the wiki on HDI.

The maps are colored according to “subunits,” or provinces (which are like American states, such as Nebraska).

Brazil, India, and South Africa are multi-party democracies, while the other two are not. So what do all five have in common?

Rent isn’t a four-letter word

download (3)

Inspired by the publication this week of NYU scholar Alain Bertaud‘s critical new book Order without Design: How Markets Shape Cities (MIT press), Sandy Ikeda‘s pre-book development series Culture of Congestion over at Market Urbanism, and London YIMBY, here is a note on housing reform.

Classical liberals see the economic solution to housing as relatively simple: increase supply to better meet demand. By contrast, the political economy of housing is almost intractably complex. The reason for this is that there are endless externalities associated with new housing: access to light, picturesque landscape, open space and uncongested roads just for starters. These gripes and grievances are the bread and butter of local politics. Unlike consumer product markets, housing cannot be disentangled from these social, political and legal controversies. A successful market-based housing policy must establish institutions that not only encourage housing supply growth but navigate around these problems while doing so.

Policy reform proposals that deliberately favour increasing owner-occupied single-family homes, as tends to be the focus among market liberals in the UK (and to some extent in the US), are currently self-defeating. As justified as they were in the past to achieve a more market-friendly political settlement, they are now a barrier to achieving plentiful, affordable housing. This is because every new homeowner becomes an entrenched interest, a potential opponent to subsequent housing development in their area. They impose more political externalities than renters. I propose we cut the link between support for home ownership and housing supply policies. This would free up policymaking to focus on expanding provision by all available market-compatible means.

This should include greater encouragement of institutional landlords, especially commercial enterprises. Commercial landlords have more incentive and capability to expand supply on estates that they own, while long-term renters (unlike homeowners) have an interest in keeping rental costs low. The lack of private firms dedicated to supplying housing in England compared to much of the rest of the world is startling and yet often overlooked even by friends of free enterprise.

Innovation and the Failure of the Great Man Theory

We tend to think about innovation as inventions and particularly about the inventors associated with them: Newton, Edison, Jobs, Archimedes, Watt, Arkwright.  This Great Man Theory of incredible technical innovation is mostly implicitly held by quite a few of us, celebrating these great men and their deeds.

Matt Ridley, the author of The Rational Optimist and The Evolution of Everything among other credentials, has spent a lot of time and effort in recent years arguing against this theory. In his recent Hayek Lecture to the British Institute of Economic Affairs he convincingly outlines his case: so many independent innovations take place roughly at the same time by different people. The Great Man Theory leads us to believe that  hadn’t it been for Edison, we’ll all be in the dark and humanity deprived ofall the benefits that came with the innovation.

Not so. There were a great number of contemporary inventors who came upon versions of the lightbulb (Ridley cites 21 or 23 or them, depending on whom you include) around the same time as Edison. The story can be repeated for most other great inventions we know of: laws of thermodynamics, calculus, most metals, typewriting machines, jet engines, the ATM, Oxygen. Indeed, the phenomenon is so common that it has its own term: simultaneous invention.

It seems, in complete contrast to the Great Man Theory, that history provided a certain problem, a sufficient number of people working on solving it at a certain time, and eventually similar inventions taking place around the same time. The process is, Ridley concludes, “gradual, incremental, collective yet inescapable inevitable […] it was bound to happen when it did”.

Interestingly enough for those of us schooled and fascinated by spontaneous orders and bottom-up social and economic phenomena, the Great Man Theory is remarkably similar to other beliefs about the world. It is a symptom of the same reasoned short-comings that makes us humans susceptible to believing in zero-sum thinking, top-down organizing and “design-implies-a-designer”. Instead of grasping the deep insights of gains from trade, spontaneous order or evolution, we are tempted by the militaristically directed organizations that we believe we understand rather than the emergent order of many independently acting individuals’ trials and errors.

Precisely this bias makes us susceptible to the mistake Mariana Mazzucato has become famous for wholeheartedly embracing: the idea that, whatever the innovation, government probably did it. That government innovation is productive – or at least more productive than is commonly presumed – and indeed societies can greatly benefit from ramping up government R&D spending. Nevermind incentives, track records or statistical robustness.

Indeed, what Ridley points to is precisely that valuable and life-changing innovation cannot be directed. Admittedly, some innovation does occur in labs, but only a vanishingly small part. Mazzucato and other top-downers could have benefited greatly from listening to Ridley (or reading his book The Rational Optimist; or reading Demsetz’ devastating 1969 article ‘Information and Efficiency’).

Coming full circle and espousing the Hayekian insights, Ridley notes that the price is everything. Specifically the reduction in prices is what matters for innovations to be spread and adopted rather than the ideas themselves. Very little happens in terms of adoption and transmission until prices start to fall dramatically (hint, hint, Bitcoin… or nuclear energy, or renewable energy…). Like the printing press and the steam engine, interesting things start to happen when prices fall – not because an innovation is particularly cool in some subsection of society.

Innovation is a deeply decentralized yet deeply collective process. We face similar challenges that occassionally come to similar conclusions – and history would in all likelihood have progress exactly the same had we not had a Newton or Edison or Jobs.

Do You have Silver?

In an episode of the Netflix medieval series The Last Kingdom, the protagonist Uthred, trying to purchase a sword from a blacksmith in a town he is just passing by, is instantly asked “Do you have silver?”.

In one scene, insignificant to the plot, the series creators neatly raised some fundamental questions in monetary economics, illustrating the relative use of credit and cash and the importance of finality.

For many centuries, the very payment system between people set severe constraints on what kinds of transactions they could – or dared – engage in. There are two main ways of providing payments (with quite a few variations within these categories): cash or credit.

Cash (sometimes referred to as ‘money transactions’) refers to payments with direct finality; the economic chain is instantly settled, and gives rise to no other economic relation. Examples here would be pure barter (where one object is traded for another) or commodity money (where an object is traded for a common media of exchange, with history providing countless fascinating examples: cattle, skin, olive oil, feathers, pearls etc).

The other category, credit, involves trading someone else’s liability or incurring a new one. Modern credit cards easily comes to mind: swiping that card settles the trade between the vendor and the customer who used the card only by creating two new (future) economic relations – a promise by the credit card company to transfer funds to the vendor, and a promise by the customer to pay the credit card company at the end of the month. The same features can be – and were – applied in many early societies; I give you some of my items, and you owe me; later I may transfer this “claim” to somebody else is the community in exchange for something I wanted, and instead of owing me, you owe them.

Some of the difficulties of monetary economics are here quickly revealed. In order for credit to work, a sufficient level of trust, repeated dealings or enforcement mechanisms must exist. If one or more parties do not trust each other, the two are unlikely to trade again or cannot socially or legally force the other into upholding his or her contract, they may refuse the deal up-front and lose the benefits of trade (the “backward induct,” in Game Theory-speak). Nevertheless going through with this transaction requires a different payment system: instant finality, such as provided with cash. Here’s the conundrum that troubles monetary economists:

The frictions that are needed to make money essential typically make credit infeasible and environments where credit is feasible are ones where money is typically not essential (Ugolini, The Evolution of Central Banking, p. 169)

If we trust each other enough (or have enough repeat dealings and a system of keeping track of everyone’s debts), there is no need for cash. If there is need for cash, that means we do not trust each other (or can’t keep track/enforce debts), indicating the presence of “frictions” that make us reluctant to use credit at all.

Let’s go back to our Last Kingdom protagonist. It is clear that the two characters are strangers (no previous dealings, no trust) and from simply passing through a village, no reason for the blacksmith to believe that there may be repeat dealings. A credit transaction is thus clearly out of question. Instead he directly asks for silver (cash), which initially seems to solve the problem. However, two further issues emerge:

  1. if all transactions were like this, the amount of cash everyone must carry around in the economy would be enormous. A common problem in medieval and even early modern societies were the lack of coins. If enough cash was simply not there and recourse to credit system unfeasible, we quickly realise how difficult transacting would be.
  2. even if the customer had enough cash, the very reason they were reluctant to use credit in the first place (no trust, no repeat dealings, no credible enforcement) harms their ability to transact in cash. Howso? Because both parties can opportunistically defect from the agreement. If the sword is paid for up front, the blacksmith can take the money and run – since they are strangers and unlikely to meet again, the cost of cheating is comparatively low. If the sword is paid for at delivery, the customer can easily renege on payment once delivery is obtained.

Is there no way out?

Uthred and the blacksmith use a method most of us are familiar with – indeed, probably even used as kids – pay half up-front, and half on delivery, with the possibility of a bonus payment (tip) at the end. Risk-minimising, yet offering payoff through the gains from trade.

Good monetary economics does precisely that: illustrating how monetary systems, including payment systems, can facilitate transactions and expand rather than limit the available gains from trade. It concerns itself with one of those spheres of (economic) life that we don’t notice until they breaks down. Try completing everyday transactions in countries with small-change shortage for a neat flashback to eighteenth century Britain or U.S., or in countries impaired by hyperinflation or sanctions. Monetary economics, in essence, is fascinating in its complexity of otherwise quite mundane things. Thanks to The Last Kingdom team for illustrating that.

Economic Liberalism and (Re)Building Europe after WWII.

It is important to understand that economic recovery and growth in Europe after World War II is not as tied to Keynesianism, unfunded welfarism, and corporatism as is sometimes assumed.

The Glorious Thirty Years of European recovery from world war and subsequent growth were not due to ‘Keynesianism’ etc. The Thirty Years ended because the influence of liberal policies had weakened and the costs of other policies had accumulated to create an obviously dysfunctional system. Left-wingers (and communitarian-corporatist conservatives) who think ‘market fundamentalists’ overthrew a well functioning social and economic settlement which was behind all the economic growth and associated institution building (post-war national recovery and European Union construction) are in error. It is a major error to ignore the influence of Austrian School liberals (see the discussion by a leading current practitioner of Austrian economics, Peter Boettke) and the related Ordoliberalismus of the Freiburg School.

My remarks on what the major terms and schools in this paragraph refer to have become uncontrollably long, so they are relegated to the bottom of the post. I hope readers will have the patience to reach them.

The key points are that the German post-war Economic Miracle came from Ordo-liberal policies, while economic growth in France after Charles de Gaulle came to power for the second time in 1958 comes from the policies of Jacques Rueff, a civil servant, judge, and economist who participated in the 1938 Walter Lippmann Colloquium in Paris, a decisive event in the revival of liberal economic thinking attended by Hayek and many other notable liberal thinkers.

Such ideas have had a lot more influence in France than lazy propagators of clichés about statist France and liberal America understand. Of course, if we look at the French and American economies we can see notable ways in which the US economy is more liberal, but that should not obscure the reality that France has had good economic times and that these have come about because liberal economic policies were applied, even where, as under de Gaulle, the political narrative of the government was not liberal. The France of 1958 and after was able to stabilise institutionally after a real danger of the collapse of constitutional democracy and have a good economic period because of neoliberal economic ideas.

Some on the left think the relative revival of market liberalism in the 1970s can be rooted in the Chilean Coup of September 1973, after which economic policy was to some degree influenced by Chilean economists with doctorates from the University of Chicago. This revival of market liberalism is known as neoliberalism, a potentially useful term which came out of the Lippmann Colloquium (see below) that has unfortunately collapsed into an empty term of abuse for any kind of market thinking in government policy, wherein even the most modest accommodation of economic rationality is labelled ‘neoliberal’ and therefore extreme, authoritarian, and based on the narrow greed of the rich. It is sometimes accompanied by attempts to read enlightenment liberals as somehow ‘really’ left-liberal, social democratic, or even socialist.

The reality is that neoliberal ideas were first obviously influential on Continue reading

The Incomplete Counterfactual Fallacy

Mariana Mazzucato has some interesting ideas, but her basic thesis (which I’m guessing based only on her recent Freakonomics interview) forgets a simple fact: had the government not made GPS, not only would we not have GPS, resources would have been allocated somewhere else.

In other words, she’s right that without government involvement we’d miss all sorts of valuable things like the basic research it turns out government has financed, physical infrastructure (no matter how neglected), GPS, the specific form the Internet we got, etc., etc.

But that’s only half the story. What happens if DARPA closes shop just before starting on GPS? Those engineers end up somewhere else, the money for the project goes somewhere else, the steel and titanium for the satellites they would have built end up in some other shop.

If we could know that nothing else would have happened at that point, then GPS is a free lunch–some bold committee scooped up a handful of clay, handed it to brilliant engineers, and created something from nothing.

More likely some of those engineers would have made dozens of other projects a little bit better, and one or two of them might even have, through some series of unpredictable events, ended up creating some totally different innovation that would have put us on to an entirely different path.

Which is the better path? There’s no way to know. The people on that other path exist in a completely different paradigm from our own. It’s comparing meta-apples with meta-oranges. We are where we are and we ought to appreciate all the costs and benefits of the system we’ve inherited. I think Mazzucato is right that many of us have underrated the government. (Certainly 23-year-old-Rick was guilty of the over-complete counterfactual fallacy.)

She makes a compelling argument that Solyndra doesn’t look like such a boondoggle when you take the wider view we would expect of the smallest venture capital investor. But if it’s true that pointing at government failures is invalid, then so is pointing at government success.

What’s important is improving the future performance of our current institutional mess. To do that, I think we’re better off backing away from her broad claims and focusing on her more sensible (and jarring) arguments about how the current system encourages destructive rent seeking through intellectual property protection of basic research that might be better left in the public domain.

We have seen the algorithm and it is us.

The core assumption of economics is that people tend to do the thing that makes sense from their own perspective. Whatever utility function people are maximizing, it’s reasonable to assume (absent compelling arguments to the contrary) that a) they’re trying to get what they want, and b) they’re trying their best given what they know.

Which is to say: what people do is a function of their preferences and priors.

Politicians (and other marketers) know this; the political battle for hearts and minds is older than history. Where it gets timely is the role algorithms play in the Facebookification of politics.

The engineering decisions made by Facebook, Google, et al. shape the digital bubbles we form for ourselves. We’ve got access to infinite content online and it has to be sorted somehow. What we’ve been learning is that these decisions aren’t neutral because they implicitly decide how our priors will be updated.

This is a problem, but it’s not the root problem. Even worse, there’s no solution.

Consider one option: put you and me in charge of regulating social media algorithms. What will be the result? First we’ll have to find a way to avoid being corrupted by this power. Then we’ll have to figure out just what it is we’re doing. Then we’ll have to stay on top of all the people trying to game the system.

If we could perfectly regulate these algorithms we might do some genuine good. But we still won’t have eliminated the fundamental issue: free will.

Let’s think of this through an evolutionary lens. The algorithms that survive are those that are most consistent with users’ preferences (out of acceptable alternatives). Clickbait will (by definition) always have an edge. Confirmation bias isn’t going away any time soon. Thinking is hard and people don’t like it.

People will continue to chose news options they find compelling and trustworthy. Their preferences and priors are not the same as ours and they never will be. Highly educated people have been trying to make everyone else highly educated for generations and they haven’t succeeded yet.

A better approach is to quit this “Rock the Vote” nonsense and encourage more people to opt for benign neglect. Our problem isn’t that the algorithms make people into political hooligans, it’s that we keep trying to get them involved under the faulty assumption that people are unnaturally Vulcan-like. Yes, regular people ought to be sensible and civically engaged, but ought does not imply can.

A Millennial’s New Perspective on Home Ownership

The last few years I’ve loudly protested that home ownership is overrated; it’s a bad investment plus lots of responsibility. And yet, this summer my fiance and I bought a 100 year old house on the south shore of Long Island.

Yes, I have lost my mind.

I basically stand by my earlier position, but with greater nuance. Owning a home is a complicated undertaking. But it’s given me a greater appreciation for the nuance involved in managing real estate.

Home ownership is a great big Gordian knot of inter-dependencies. It’s massive set of knowledge problems wrapped in externality problems.There’s a massive role for local knowledge which means policy makers’ attention should be less focused on things like home ownership rates, and more on guiding the right people into the right places to take advantage of that local knowledge.

With local knowledge comes local politics. I don’t know anything about local politics, but expect more posts about what’s going on in my town hall over the next few decades.

So what have I learned in this first month of home ownership?

  • There’s something to be said about pride in ownership

It’s still a real trip to turn on my lights in my kitchen so I can do my laundry in my laundry machines. I didn’t think I’d enjoy it this much. The endowment effect is real. One effect has been to increase my interest in contributing to local public goods via civic engagement and other routes.

I haven’t been to a town hall meeting yet, but I plan on going to one tomorrow. I suspect it will be awful. But I’m walking distance, so I’ll be a little bit drunk.

  • The real estate market has some serious frictions

This might be obvious, but it’s interesting. There are artificial and natural obstacles to the efficient use of real estate. Transaction costs are significant and property rights issues are hairy.

Buying a house is a complicated transaction and going through the process has really made clear to me how difficult it is to commodify land. Each piece of land has a unique location and history. Information asymmetries are substantial. The neighborhood you’re buying into is utterly out of your control. Put simply: Amazon won’t be selling real estate any time soon.

Part of the reason I’m happy with buying a house is that our rent had been increasing about $100/month/year. Land lords absolutely take advantage of real estate frictions to charge as much as they can. The alternative (which I chose) is to lock-in to a specific property.

  • The required knowledge to operate a home is significant and difficult to evaluate.

It takes a lot of knowledge to manage a house. If I were to take a wild guess (at this non-quantifiable variable), I’d say that between 5% and 50% of a homeowner’s brain is necessary to operate a house. Even if you bring in experts to do everything, evaluating those experts is a lot of work.

There are repairs and upgrades to make, and my formal education prepared me for exactly none of those projects. On the other hand, I’ve got the Internet. Without YouTube and Reddit I’d be a half dozen unlucky mistakes away from homelessness.

On the other other hand, I’ve learned a ton of stuff I’ve got no use for. Like how to grow asparagus (which it turns out it isn’t worth doing except out of boredom).

You can’t evaluate knowledge until it’s too late. And there’s more to learn than you ever will, so you have to make mistakes. It’s true of home ownership and it’s true of life more generally.

  • Gardening is a real trip.

In History of Economic Thought professor Gonzalez shared a story about two economists meeting in Switzerland during WWII. On showing his vegetable garden to the visiting economist, the visitor said “that’s not a very efficient way to grow food,” to which the gardener said, “yes, but it’s a very efficient way to grow utility.”

I’ve wanted to garden for some time, but the market for gardens is thin. So now I’m starting with almost no useful experience. My public stance has been that lawns are boring and dumb. But figuring out how to manage a little ecosystem ain’t easy. I now get why someone would just put in a lawn and be done with it.

At my old apartment complex the entire ecosystem was made of: humans, trees, lawns, cockroaches. I suspect the cockroaches did so well because all their competition was poisoned away. As an emergent order guy, I’m not really into that. But I get it now. In the same way the king wants everyone living in neat little taxable rows my life would be easier if I could just slash and burn all the complexity out of my yard.

Tl;dr: My biggest surprise as a new home owner is just how big a cognitive load owning a house is. You hear homeowners talk about how much work it can be, but I think it’s rare to hear someone talk about how much know-how is required.

Given the capacity to generate externalities, I’m a bit surprised that there isn’t more public policy devoted to issues of home ownership* (beyond subsidizing finance and increasing barriers to entry). I supposed I’ll learn a lot more about these issues as I learn about local politics.

*That isn’t to say I think it’s a good idea to get the government involved in trying to tell people how to go about the business of daily life. I think homeowners are (basically) doing fine left to their own devices.

Evidence-based policy needs theory

This imaginary scenario is based on an example from my paper with Baljinder Virk, Stella Mascarenhas-Keyes and Nancy Cartwright: ‘Randomized Controlled Trials: How Can We Know “What Works”?’ 

A research group of practically-minded military engineers are trying to work out how to effectively destroy enemy fortifications with a cannon. They are going to be operating in the field in varied circumstances so they want an approach that has as much general validity as possible. They understand the basic premise of pointing and firing the cannon in the direction of the fortifications. But they find that the cannon ball often fails to hit their targets. They have some idea that varying the vertical angle of the cannon seems to make a difference. So they decide to test fire the cannon in many different cases.

As rigorous empiricists, the research group runs many trial shots with the cannon raised, and also many control shots with the cannon in its ‘treatment as usual’ lower position. They find that raising the cannon often matters. In several of these trials, they find that raising the cannon produces a statistically significant increase in the number of balls that destroy the fortifications. Occasionally, they find the opposite: the control balls perform better than the treatment balls. Sometimes they find that both groups work, or don’t work, about the same. The results are inconsistent, but on average they find that raised cannons hit fortifications a little more often.

A physicist approaches the research group and explains that rather than just trying to vary the height the cannon is pointed in various contexts, she can estimate much more precisely where the cannon should be aimed using the principle of compound motion with some adjustment for wind and air resistance. All the research group need to do is specify the distance to the target and she can produce a trajectory that will hit it. The problem with the physicist’s explanation is that it includes reference to abstract concepts like parabolas, and trigonometric functions like sine and cosine. The research group want to know what works. Her theory does not say whether you should raise or lower the angle of the cannon as a matter of policy. The actual decision depends on the context. They want an answer about what to do, and they would prefer not to get caught up testing physics theories about ultimately unobservable entities while discovering the answer.

Eventually the research group write up their findings, concluding that firing the cannon pointed with a higher angle can be an effective ‘intervention’ but that whether it does or not depends a great deal on particular contexts. So they suggest that artillery officers will have to bear that in mind when trying to knock down fortifications in the field; but that they should definitely consider raising the cannon if they aren’t hitting the target. In the appendix, they mention the controversial theory of compound motion as a possible explanation for the wide variation in the effectiveness of the treatment effect that should, perhaps, be explored in future studies.

This is an uncharitable caricature of contemporary evidence-based policy (for a more aggressive one see ‘Parachute use to prevent death and major trauma related to gravitational challenge: systematic review of randomised controlled trials’). Metallurgy has well-understood, repeatedly confirmed theories that command consensus among scientists and engineers. The military have no problem learning and applying this theory. Social policy, by contrast, has no theories that come close to that level of consistency. Given the lack of theoretical consensus, it might seem more reasonable to test out practical interventions instead and try to generalize from empirical discoveries. The point of this example is that without theory empirical researchers struggle to make any serious progress even with comparatively simple problems. The fact that theorizing is difficult or controversial in a particular domain does not make it any less essential a part of the research enterprise.

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.

Animation Review #1: Burn the Witch

I am a big fan of animation, but I often have to ‘turn my brain off’ to enjoy a comic trying to make political commentary. With rare exceptions, like the Incredibles series, the industry has a strong statist bent. The industry is so statist that Superman: Red Son, a story line with the premise that Superman landed in the Soviet Union instead of the United States, ends with the message that communism would work if only it were a bit more democratic. Note that I say statist bent, as opposed to leftist bent. They are smaller in number, but there are several conservative comics (e.g. the Kingsman) that leave a statist aftertaste.

I can’t do much on the supply side of liberty-friendly comics, but I can at least highlight those comics that I think fellow libertarians might enjoy via blog posts.

First off is Burn the Witch, a new comic series published by Shonen Jump. I was pleasantly surprised when I read through Tite Kubo’s Burn the Witch. Tite Kubo is best known for authoring Bleach, a comic about Japanese school children fighting demons in fantasy Mexico.

Dragons.png

Burn the Witch is about Anglo-Japanese school children fighting demons in fantasy Britain. The twist? Unlike their counterparts in fantasy Mexico, the British demons (referred to as ‘Dragons’ in-series) aren’t killed outright. Instead they are raised for the resources they provide. Only ‘bad’ demons who are killing humans or otherwise causing destruction are killed. It is noteworthy that the protagonists refer to themselves as ‘conservationists’. They kill the occasional demon, providing the story with action scenes when doing so, but their primary purpose is to conserve them. In an off hand comment the protagonists note that their fantasy Mexican counterparts are barbaric and indiscriminately kill their demons.

Contrary to the protagonist’s comments, it isn’t that individual fantasy Mexicans are barbaric so much that fantasy Mexico doesn’t recognize property rights in demons. Since no one has a property right in demons, no one has an incentive to conserve, much less domesticate, them in fantasy Mexico. Fantasy Britain enjoys strong property rights and consequently has minimal problems associated with its demons. One of the protagonists is ethnically from fantasy Mexico, but seems to be thriving under fantasy Britain’s rules. The story’s lesson? Property rights matter.

Only one chapter of Burn the Witch has been published thus far, and it’s unclear if it’ll become a recurring series, but I like what I’ve seen so far.
