Legal Immigration Into the United States (Part 20): Transitional Measures and Conclusions

We must recognize than any orderly system used to select and admit immigrants involves a degree of bureaucratic slowness. Hence, the existing family preference-based program would have to be extended for several years, maybe as long as ten, while accepting no more new applications. It’s likely that the compromise solution would even have to be some sort of measure that guarantees that the last direct descendants and direct ascendants of existing immigrants have been accommodated.

To remedy the labor rigidity consequent on the abolition of family preference as the primary source of admission, the US might re-instate a new version of the 1942-1964 bracero program. I refer to a system of admission of temporary contractual workers guaranteed a minimum wage and decent living conditions by employers for a stated period. Temporary immigrants admitted in this manner would have no expectation of permanent admission to the US. The problem of “stay-overs” could be solved through a conventional bonding system. (I am puzzled about why bonding has not yet been tried in connection to immigration.) The work sojourns would have to be made renewable in law so that the US might preserve the option of keeping temp. workers who had acquired valuable and rare skills during, or even before their first, or following stay in-country. In exceptional cases, temp. workers in such a program could be channeled to the new F-1B program, perhaps with credit given for experiences working in the US and for cultural adjustment.


In summary: I deplore two features of current public discussions of legal immigration: They are ill-informed to an astonishing degree; and, they are often crude, lacking in both subtlety and imagination, like an argument between two people who keep cutting each other off. Unless one formulates a systematic alternative to the current system, one squarely separating immigration based on altruism from merit-based immigration, immigration based on the expected immigrants contributions to American society, the helter-skelter liberal project will continue to prevail. It is now prevailing by default in the minds of  most Americans. Those who have the energy to resist it too often limit their response to a blind “No!”In the end,  if no countervailing project emerges forcefully, we will witness the establishment of a statist one-party system in the US. Libertarians, among others, should hurry to confront their close friends and relatives who toy with the dangerous delusion of open borders.

Legal Immigration Into the United States: The H-1B Visas Confusion and Controversy (Part 2 of 6)

This is the right place for a painful digression. It’s painful because it’s about a program related to immigration that is both confusing and calculated, as if by design, to become controversial. Yet, as I argue below, toward the end of this essay, it’s a program with promise.

Many middle-class foreigners with college degrees are in the US on temporary working visas. By numbers, the main category of working visas is the H-1B visa. (This is confusing, but there is currently no such thing as an H-1A visa.) Holders of the H-1B visa must meet specific educational qualifications. They are sponsored by American employers – but also by employers who look much like labor contractors based abroad. They may stay in the US for a period of three years, renewable for an additional three years. That’s except if they work for a university or for a research institute, in which case their visa is pretty much eternal. Although the number of visas allotted each year is capped, by accumulation, the program involves significant numbers of people, about 350,000 in 2016. Some or most H-1B visas are allocated by lottery on an annual basis. (It’s completely separate from the diversity lottery described above [in Part 1], as I said.)

The rationale behind the H-1B visa is to supply workers in specialties that industrial and other organizations cannot find domestically. The program is controversial for two reasons. Continue reading

How poor was 18th century France? Steps towards testing the High-Wage Hypothesis (HWE)

A few days ago, one of my articles came online at the Journal of Interdisciplinary HistoryIt is a research note, but as far as notes go this one is (I think) an important step forwards with regards to the High-Wage Hypothesis (henceforth HWE for high-wage economy) of industrialization.

In the past, I explained my outlook on this theory which proposes that high wages relative to energy was a key driver of industrialization. As wages were high while energy was cheap, firms had incentives to innovate and develop labor-saving technologies.  I argued that I was not convinced by the proposition because there were missing elements to properly test its validity. In that post I argued that to answer why the industrial revolution was British we had to ask why it was not French (a likely competitor). For the HWE to be a valid proposition, wages had to be higher in England than in France by a substantial margin. This is why I have been interested in living standards in France.

In his work, Robert Allen showed that Paris was the richest city in France (something confirmed by Phil Hoffman in his own work). It was also poorer than London (and other British cities). The other cities of France were far behind. In fact, by the 18th century, Allen’s work suggests that Strasbourg (the other city for which he had data) was one of the poorest in Europe.

In the process of assembling comparisons between Canada and France during the colonial era (from the late 17th to the mid-18th centuries), I went to the original sources that Allen used and found that the level of living standards is understated. First, I found out that the wages were not for Strasbourg per se. They applied to a semi-rural community roughly 70km away from Strasbourg.  Urban wages and rural wages tend to differ massively and so they were bound to show lower living standards. Moreover, the prices Allen used for his basket applied to urban settings. This means that the wages used were not comparable to the other cities used. I also found out that the type of work that was reported in the sources may not have belonged to unskilled workers but rather to semi-skilled or even skilled workers and that the wages probably included substantial in-kind payments.

Unfortunately, I could not find a direct solution to correct the series proposed by Allen. However, there were two ways to circumvent the issue. The most convincing of those two methods relies on using the reported wages for agricultural workers. While this breaks with the convention established by Allen (a justifiable convention in my opinion) of using urban wages and prices, it is not a problem if we compare with similar types of wage work. We do have similar data to compare with in the form of Gregory Clark’s farm wages in England. The wage rates computed by Allen placed Strasbourg at 64% of the level of wages for agricultural workers in England between 1702 and 1775. In comparison, the lowest of the agricultural wage rates for the Alsatian region places the ratio at 74%. The other wage rates are much closer to wages in England.  The less convincing methods relies on semi-skilled construction workers – which is not ideal. However, when these are compared to English wages, they are also substantially higher.

Overall, my research note attempts a modest contribution: properly measure the extent to which wages were lower in France than in Britain. I am not trying to solve the HWE debate with this. However, it does come one step closer to providing the information to do so. Now that we know that the rest of France was not as poor as believed (something which is confirmed by the recent works of Leonardo Ridolfi and Judy Stephenson), we can more readily assess if the gap was “big enough” to matter.  If it was not big enough to matter, then we have to move to one of the other five channels that could confirm the HWE (at least that means I have more papers to write).

Do risk preferences account for 1.4 percentage points of the gender pay gap?

A few days ago, this study of gender pay differences for Uber drivers came out. The key finding, that women earned 7% less than men, was stunning because Uber uses a gender-blind algorithm. The figure below was the most interesting one from the study as it summarized the differences in pay quite well.


To explain this, the authors highlight a few explanations borne out by the data: men drive faster allowing them to have more clients; men have spent more time working for Uber and have more experience that may be unobserved; choices of where and when to drive matters. It is this latter point that I find fascinating because it speaks to an issue that I keep underlining regarding pay gaps when I teach.

For reasons that may be sociological or biological (I am agnostic on that), men tend to occupy jobs that have high rates of occupational mortality (see notably this British study on the topic) in the forms of accidents (think construction, firemen) or diseases (think miners and trashmen). They also tend to take the jobs in further removed areas in order to gain access to a distance premium (which is a form of risk in the sense that it affects  family life etc.). The premiums to taking risky jobs are well documented (see notably the work of Kip Viscusi who measured the wage premium accruing to workers who were employed in bars where smoking was permitted). If these premiums are non-negligible but tend to be preferred by men (who are willing to incur the risk to be injured or fall sick), then risk preferences matter to the gender wage gap.

However, there are hard to properly measure in order to assess the share of the wage gap truly explained by discrimination. Here with the case of Uber, we can get an idea of the amplitude of the differences. Male Uber drivers prefer riskier hours (more risks of having an inebriated and potentially aggressive client), riskier places (high traffic with more risks of accidents) and riskier behavior (driving faster to get more clients per hour).  The return to taking these risks is greater earnings. According to the study, 20% of the gap stems from this series of choices or roughly 1.4 percentage points.

I think that this is significantly large to warrant further consideration in the future in the debate. More often than not, the emphasis is on education, experience, marital status, and industry codes (NAICS code) to explain wage differences. The use of industry codes has never convinced me. There is wide variance within industries regarding work accidents and diseases. The NAICS codes industries by wide sectors and then by sub-sectors of activities (see for example the six-digits codes to agriculture, forestry, fishing and hunting here). This does not allow to take account of the risks associated with a job. There are a few study that try to account for this problem, but there are … well … few in numbers. And rarely are they considered in public discussions.

Here, the Uber case shows the necessity to bring back this subtopic in order to properly explain the wage gap.

On Monopsony and Legal Surroundings

A few days ago, in reply to this December NBER study, David Henderson at EconLog questioned the idea that labor market monopsonies matter to explain sluggish wage growth and rising wage inequality. Like David, I am skeptical of this argument. However, I am skeptical for different reasons.

First, let’s point out that the reasoning behind this story is well established (see notably the work of Alan Manning). Firms with market power over a more or less homogeneous labor force which must assume a disproportionate amount of search costs have every incentive to depress wages. This can lead to reductions in growth as, notably, it discourages human capital formation (see these two papers here and here as examples). As such, I am not as skeptical of “monopsony” as an argument.

However, I am skeptical of “monopsony” as an argument. Well, what I mean is that I am skeptical of considering monopsony without any qualifications regarding institutions. The key condition to an effective monopsony is the existence of barriers (natural and/or legal to mobility). As soon as it is relatively easy to leave a small city for another city, then even a city with a single-employer will have little ability to exert his “market power” (Note: I really hate that word). If you think about it simply through these lenses, then all that matters is the ability to move. All you need to care about are the barriers (legal and/or natural) to mobility (i.e. the chance to defect).

And here’s the thing. I don’t think that natural barriers are a big deal. For example, Price Fishback found that the “company towns” im the 19th century were hardly monopsonies (see here, here, here and here). If natural barriers were not a big deal, they are certainly not a big deal today. As such, I think the action is largely legal. My favorite example is the set of laws adopted following the Emancipation of slaves in the United States which limited the mobility (by limiting the chances of Northerners hiring agents to come who would act as headhunters in the South). That is a legal barrier (see here and here). I am also making that argument regarding the institution of seigneurial tenure in Canada in a working paper that I am reorganizing (see here).

What about today? The best example are housing restrictions? Well, housing construction and zoning regulations basically make the supply of housing quite inelastic. The areas where these regulations are the most severe are also, incidentally, high productivity areas. This has two effects on mobility. The first is that low-productivity workers in low-productivity areas cannot easily afford to move to the high-productivity area. As such, you are reducing their options of defection and increasing the likelihood that they will not look. You are also reducing the pool of places to apply which means that, in order to find a more remunerative job, they must search longer and harder (i.e. you are increasing their search costs). The second effect is that you are also tying workers to the areas they are in. True, they gain because the productivity becomes capitalized in the potential rent from selling any property they own. However, they are in essence tied to the place. As such, they can be more easily mistreated by employers.

These are only examples. I am sure I could extend the list to reach the size of the fiscal code (well, maybe not that much). The point is that “monopsony” (to the extent that it exists) is merely a symptom of other policies that either increase search costs for workers or reduce the number of options for defections. And I do not care much for analyzing symptoms.
