That is my new opinion piece for The Washington Post, derived from my Big Business: A Love Letter to an American Anti-Hero. Here is one excerpt:
Yet big business often has been a strong progressive force in U.S. history, not only by providing jobs but also by spreading emancipatory practices and norms.
For instance, McDonald’s, General Electric, Procter & Gamble and many of the big tech companies offered health care and other legal benefits for same-sex partners well before the Supreme Court legalized gay marriage in 2015. In addition to dramatically improving the lives of thousands of Americans, the companies’ moves put a mainstream stamp of approval on the notion of same-sex marriage itself.
The larger the business, the more tolerant the institution is likely to be of employee and customer personal preferences. A local baker might refuse to make a wedding cake for a gay couple for religious reasons, but Sara Lee, which tries to build very broadly based national markets for its products, is keen on selling cakes to everyone. The bigger companies need to protect their broader reputations and recruit large numbers of talented workers, including from minority groups. They can’t survive and grow just by cultivating a few narrow networks as either their workers or customers.

Not as much as many people think. As you may know, yesterday’s job market was quite good (NYT) and it is now many years of labor market recovery. Does this mean the Fed should have been easier with money say two or three years ago? No, that doesn’t follow. Let’s talk through a few points:
1. Aggregate demand shocks are major causes of recessions, and when they come you want the central bank to lean against them very, very hard, even if that means higher than average price inflation.
2. The early problems are mostly nominal. For whatever reasons (morale? long-term implicit contracts?), firms lay off some workers rather than cutting their nominal wages. This is a big reason why downturns involve so much unemployment, but to the extent the central bank can keep up nominal demand, at least some of this unemployment can be avoided or at least smoothed out over time.
3. Once those workers are unemployed, nominal stickiness starts to cease to be the major problem. Real rigidities and stickiness become progressively more important with the passage of time. First, the unemployed don’t even have a nominal wage to be sticky in the first place, and yes some of them are excessively stubborn with their reservation wages for accepting new jobs but that looks suspiciously like voluntary unemployment, albeit with some behavioral irrationality mixed in. But no, the main problem still is not voluntary unemployment, I am saying if the only rigidities were nominal it would be a problem of voluntary unemployment, a very different claim. I’ll come back to this shortly.
4. In the very early stages of a recession, there might simply be no jobs available, period, due to uncertainties and liquidity shocks. But usually within a year or two, a whole host of jobs open up, they just may not be good jobs for many of the unemployed. Often they are bad jobs, for reasons which relate to real rigidities, not nominal rigidities. Individuals need to be rematched to new jobs, and that process may or may not go well.
5. Here is a typical real rigidities story (but not the only one): you aspire to be an upper to mid level manager, and you are offered a job as a cashier at Walmart, or you could get such a job if you tried. You don’t take the job, because you fear its presence on your resume will shunt you onto a permanently lower career track. That is indeed a problem, and it is a real rigidity, not a nominal one. It can keep you unemployed, even if you might otherwise prefer to have the work on a temporary basis.
6. As the economy grows in real terms, the quality of jobs available will be upgraded, and eventually the unemployed are offered jobs which are worth taking. This process can be fast or slow, but in the recent recovery it has been relatively slow.
7. As more people are taking jobs, yes demand is rising but supply is rising also. The two are rising together. It is not wrong to say “greater demand is reemploying people,” but it is misleading. It is more accurate to say “real demand is rising, coincident with growing output, job quality is improving, uncertainty is being resolved, and the economy is doing a successively better job at solving the matching problem in its labor markets.”
8. In that same setting, simply boosting nominal demand with lower interest rates and higher price inflation won’t necessarily help employment much. You might get a slight labor supply increase through the not very impressive Lucas supply curve (people confusing nominal and real changes).
8b. To be sure, there is likely no harm from the easier monetary policy since price inflation has been slightly below target. I do not hate these proposed monetary easings, I just don’t think they are likely to matter much. Telling me that “higher demand has been reemploying workers” doesn’t impress me. Telling me “the labor market recovery has been underway for a long time” also does not impress me. Neither claim implies that a nominal push to demand will do the trick, if anything they might imply the contrary.
9. If the labor market recovery has been underway for a long time, that is a sign the coordination problem has been a real one rather than a nominal one. It is a sign that earlier Fed easing simply may not have mattered much.
10. You might notice that outside of emergency situations, such as 1929 or 2008 (see point #1), economists struggle mightily to demonstrate that money matters at all. I think Christina Romer has shown that surprise deflationary shocks do matter and are bad. After that, it is still up in the air, as indeed this analysis implies.
Everything I am writing is consistent with mainstream research economics, and the best and most sophisticated versions of Keynesian economics. I know it is not usually what you read on the internet. As a side note and exercise, it is worth pondering what this same framework might imply for the efficacy of fiscal policy, noting the answer will be “under what conditions?” rather than yes or no.
Consumers, employees, students, and others are often subjected to “sludge”: excessive or unjustified frictions, such as paperwork burdens, that cost time or money; that may make life difficult to navigate; that may be frustrating, stigmatizing, or humiliating; and that might end up depriving people of access to important goods, opportunities, and services. Because of behavioral biases and cognitive scarcity, sludge can have much more harmful effects than private and public institutions anticipate. To protect consumers, investors, employees, and others, firms, universities, and government agencies should regularly conduct Sludge Audits to catalogue the costs of sludge, and to decide when and how to reduce it. Much of human life is unnecessarily sludgy. Sludge often has costs far in excess of benefits, and it can have hurt the most vulnerable members of society.
That is the abstract of a new paper by Cass Sunstein.
Intergenerational mobility is higher among college graduates than among people with lower levels of education. In light of this finding, researchers have characterized a college degree as a great equalizer leveling the playing field, and proposed that expanding higher education would promote mobility. This line of reasoning rests on the implicit assumption that the relatively high mobility observed among college graduates reflects a causal effect of college completion on intergenerational mobility, an assumption that has rarely been rigorously evaluated. This article bridges this gap. Using a novel reweighting technique, I estimate the degree of intergenerational income mobility among college graduates purged of selection processes that may drive up observed mobility in this subpopulation. Analyzing data from the National Longitudinal Survey of Youth 1979, I find that once selection processes are adjusted for, intergenerational income mobility among college graduates is very close to that among non-graduates. This finding suggests that expanding the pool of college graduates per se is unlikely to boost intergenerational income mobility in the United States. To promote mobility, public investments in higher education (e.g., federal and state student aid programs) should be targeted at low-income youth.
Another form of domestic politics? Here is Andrew Batson on his blog:
The Belt and Road is really the expansion of a specific part of China’s domestic political economy to the rest of the world. That is the nexus between state-owned contractors and state-owned banks, which formed in the domestic infrastructure building spree construction that began after the 2008 global financial crisis (and has not yet ended).
Local governments discovered they could borrow basically without limit to fund infrastructure projects, and despite many predictions of doom, those debts have not yet collapsed. The lesson China has learned is that debt is free and that Western criticisms of excessive infrastructure investment are nonsense, so there is never any downside to borrowing to build more infrastructure. China’s infrastructure-building complex, facing diminishing returns domestically, is now applying that lesson to the whole world.
In Belt and Road projects, foreign countries simply take the place of Chinese local governments in this model (those who detect a neo-imperial vibe around the Belt and Road are, in this sense, onto something). Even the players are the same. In the 1990s, China Development Bank helped invent the local-government financing vehicle structure that underpinned the massive domestic infrastructure. Now, China Development Bank is one of the biggest lenders for overseas construction projects.
Those who defend the Belt and Road against the charge of debt-trap diplomacy are technically correct. But those same defenders also tend to portray the lack of competitive tenders and over-reliance on Chinese construction companies in Belt and Road projects as “problems” that detract from the initiative’s promise. They miss the central role of the SOE infrastructure-complex interest group in driving the Belt and Road. Structures that funnel projects funded by state banks to Chinese SOEs aren’t “problems” from China’s perspective–they are the whole point.
The fact that this model was dubbed the “Belt and Road Initiative” and turned into a national grand strategy by Xi Jinping effectively gave the SOE infrastructure complex carte blanche to pursue whatever projects they can get away with. These projects were no longer just money-makers for SOEs, but became a way to advance China’s national grand strategy–thereby immunizing them from criticism and scrutiny.
And Andrew is always worth reading on music and jazz.
That is the driving question behind my latest Bloomberg column, perhaps some of you can be talked up to one in a thousand. Here is the opening bit:
For the last several years, the U.S. military has observed an increase in what it calls “unexplained aerial phenomena.” The rest of us may know them by their more common name — unidentified flying objects — and we should all strive, as the Navy is doing, to take these reports more seriously.
Sometimes, according to the Washington Post, well-trained military pilots “claimed to observe small spherical objects flying in formation. Others say they’ve seen white, Tic Tac-shaped vehicles. Aside from drones, all engines rely on burning fuel to generate power, but these vehicles all had no air intake, no wind and no exhaust.” They also appear to exceed all known aircraft in speed and have been described by a former deputy assistant secretary of defense as embodying a “truly radical technology.”
Meanwhile, Avi Loeb, chair of the Harvard astronomy department, recently suggested that a passing object in space, named Oumuamua, might be a lightsail from an advanced alien civilization, as evidenced by its apparently strange movements.
Also keep in mind the history of the New World before the European arrival and conquest. There were legends of fair-skinned visitors from abroad, perhaps stemming from the Vikings and their explorations, but one day this “alien contact” turned out to be very real indeed — through Columbus, Cortés and others. To be oblivious of another civilization for a long time, and then suddenly encounter it, is a common theme in human history. Perhaps this has not happened for the last time.

Here is Naunihal Singh interviewed by FP on the uprising in Venezuela–very much in the tradition of Tullock’s classic on Autocracy which argued that so-called popular uprisings almost always mask internal coups and Chwe’s work on the importance of common knowledge for coordinating action.
Naunihal Singh: Here’s the thing: At the heart of every coup, there is a dilemma for the people in the military. And it goes like this: You need to figure out which side you’re going to support, and in doing so, your primary consideration is to avoid a civil war or a fratricidal conflict.
If done correctly, a coup-maker will get up there and make the case that they have the support of everybody in the military, and therefore any resistance is minor and futile and that everyone should, either actively or passively, support the coup. And if you can convince people that’s the case, it becomes the case.
But in order to do this, you need to convince everyone not only that you’re going to succeed, but that everyone else thinks that you’re going to succeed. And in order to do that, you need to use some sort of public broadcast.
What is important here is the simultaneity of it. It’s the fact that you know that everybody else has heard the same thing as you have. And social media—Twitter—doesn’t do that.
FP: And can you tell us why Twitter isn’t really going to cut it?
NS: What broadcasts do is they create collective belief in collective action. Coup-making is about manipulating people’s beliefs and expectations about each other.
If I’m commanding one unit, even if I see Juan Guaidó’s official Tweet, I’m not going to even know how many other people within the military have seen it. What’s more, I would have good reason to believe that the penetration of this tweet within the military will be pretty slight. I have no idea what internet access is like inside the Venezuelan military right now. But I imagine that most military people don’t follow Juan Guaidó’s feed, because doing so would expose them to sanctions from military intelligence, and in that context, it would very clearly mark them as a traitor. But the other thing is this—what we think of as viral tweets operate on a far slower time scale than a broadcast. And coups happen in hours.
…FP: Guaidó delivered his message to Venezuela this morning standing in front of men in green fatigues with helmets on, and armored vehicles in the background. Tell me about how Guaidó is drawing on familiar visual strategies of coups. What did he get right and wrong about the optics?
NS: It’s a dawn video, which is very classic. But there’s a problem: Guaidó does have military people there, but in order to be more credible he would have had a high-ranking military figure standing side by side with him. He can’t make it appear like there’s a military takeover. He also has to make it clear that this is a civilian action and that it’s within the constitution. As a result, he’s standing at the front and he’s got some soldiers in the back, but because they are low-ranking soldiers, it doesn’t mean very much, and it doesn’t carry very much weight.

Here is my previous post on the third cohort of winners, with links to the first and second cohorts. Here is my post on the underlying philosophy behind Emergent Ventures. You can apply here.
Caplan and Weinersmith, in their splendid forthcoming graphic novel, present some rebuttals to the “cultural critique” of open borders. For instance (and here I am presenting their views):
1. The average immigrant has political views which poll as pretty close to those of the average American. They don’t even by huge margins favor more immigration. (The author do admit that low-skilled immigrants do favor significantly less free speech, in any case on all of these points they do present actual numbers and visuals.)
2. Support for the welfare state remains strong in Western European nations, even as they have taken in many more migrants.
3. Open borders once before produced American political culture.
4. In “deep roots” terms, the United States already has a mediocre ancestry score, yet America has very high gdp and relatively strong political institutions.
5. There is an extended response to Garett Jones on IQ which I do not feel I can summarize well. Toward the end, it is noted that babies adopted from poorer countries into richer countries typically do very well later in life.
6. The end of this chapter proclaims: “Open borders won’t destroy our freedom. It’s going to bring freedom to all of mankind.”
I will again repeat my earlier point: the value and import of this new book does not very much depend on your actual opinion of open borders. Still, if you would like to hear my views, I’ll repeat my earlier discussion:
And no I do not favor open borders even though I do favor a big increase in immigration into the United States, both high- and low-skilled. The simplest argument against open borders is the political one. Try to apply the idea to Cyprus, Taiwan, Israel, Switzerland, and Iceland and see how far you get. Big countries will manage the flow better than the small ones but suddenly the burden of proof is shifted to a new question: can we find any countries big enough (or undesirable enough) where truly open immigration might actually work?
In my view the open borders advocates are doing the pro-immigration cause a disservice. The notion of fully open borders scares people, it should scare people, and it rubs against their risk-averse tendencies the wrong way. I am glad the United States had open borders when it did, but today there is too much global mobility and the institutions and infrastructure and social welfare policies of the United States are, unlike in 1910, already too geared toward higher per capita incomes than what truly free immigration would bring. Plunking 500 million or a billion poor individuals in the United States most likely would destroy the goose laying the golden eggs. (The clever will note that this problem is smaller if all wealthy countries move to free immigration at the same time, but of course that is unlikely.)
In any case, do buy the Caplan and Weinersmith book. I have now begun to think there should be a book like this, or two, for every major political issue of import.
It now seems there will be a Conversations with Tyler with him, no associated public event. So what should I ask him?
2. “Indeed, both studies revealed that while social liberals were overall more sympathetic to poor people than social conservatives, reading about White privilege decreased their sympathy for a poor White (vs. Black) person. Moreover, these shifts in sympathy were associated with greater punishment/blame and fewer external attributions for a poor White person’s plight. We conclude that, among social liberals, White privilege lessons may increase beliefs that poor White people have failed to take advantage of their racial privilege—leading to negative social evaluations.” Link here.
Here is the announcement, here is the opening paragraph of the summary:
Emi Nakamura is an empirical macroeconomist who has greatly increased our understanding of price-setting by firms and the effects of monetary and fiscal policies. Emi’s distinctive approach is notable for its creativity in suggesting new sources of data to address long-standing questions in macroeconomics. The datasets she uses are more disaggregated, or higher-frequency, or extending over a longer historical period, than the postwar, quarterly, aggregate time series that have been the basis for most prior work on these topics in empirical macroeconomics. Her work has required painstaking analysis of data sources not previously exploited, and at the same time displays a sophisticated understanding of the alternative theoretical models that the data can be used to distinguish.
Congratulations! And there is much more of interest at the link. And here are previous (and numerous) MR posts on her work.
The Peter Principle is the observation that if people are good at doing their jobs they will be promoted. It follows that eventually everyone will be doing a job that they are not good at (otherwise they would have been promoted). The Peter Principle is tongue in cheek but it’s stuck around because it has an element of truth. Alan Benson, Danielle Li, Kelly Shue have put the principle to the test (summary here) by looking at promotions and performance of some 40,000 sales workers across 131 firms. Sales workers are a good place to look for the principle in action because it seems natural to promote the best sales people yet the best sales people do not necessarily make the best managers.
Figure One summarizes the main result: The best sales people as measured by sales revenue are more likely to be promoted (top) but their value added as managers actually declines in their (pre-promotion) sales revenues (bottom). The result isn’t difficult to believe, the best sales staff do not necessarily make the best managers, the best football players do not necessarily make the best coaches, the best professors do not necessarily make the best deans. But the result is deeper than this point because it raises questions about management. How can firms motivate top sales performers without promoting them to positions for which they may not be suitable? If sales revenue isn’t a good metric for manager potential, what is? The authors write:
We provide evidence that the Peter Principle may be the unfortunate consequence of firms doing their best to motivate their workforce. As has been pointed out by Baker et al. (1988) and by Milgrom and Roberts (1992), promotions often serve dual roles within an organisation: they are used to assign the best person to the managerial role, but also to motivate workers to excel in their current roles. If firms promoted workers on the basis of managerial potential rather than current performance, employees may have fewer incentives to work as hard.
We also find evidence that firms appear aware of the trade-off between incentives and matching and have adopted methods of reducing their costs. First, organisations can reward high performers through incentive pay, avoiding the need to use promotions to different roles as an incentive. Indeed, we find that firms that rely more on incentive pay (commissions, bonuses, etc.), also rely less on sales performance in making promotion decisions. Second, we find that organisations place less weight on sales performance when promoting sales workers to managerial positions that entail leading larger teams. That is, when managers have more responsibility, firms appear less willing to compromise on their quality.
Our research suggests that companies are largely aware of the Peter Principle. Because workers value promotion above and beyond a simple increase in salary, firms may not want to rid themselves entirely of promotion-based incentives. However, strategies that decouple a worker’s current job performance from his or her future career potential can minimise the costs of the Peter Principle. For example, technical organisations, like Microsoft and IBM have long used split career ladders, allowing their engineers to advance as individual contributors or managers. These practices recognise workers for succeeding in one area without transferring them to another.
Designing incentives is much more complicated than the carrot and the stick especially when workers contribute to firms in difficult to measure, multi-dimensional ways.
(fyi, our textbook, Modern Principles offers an introduction to incentive design).
