America does pretty well at public health
Michael S. Sparer and Anne-Laure Beaussier has a new and interesting piece on this topic, here is part of the abstract:
First, the United States outperforms its European peers on several public health metrics. Second, the United States spends a comparable proportion of its health dollar on prevention. Third, these results are due partly to a federalism twist (while all three nations delegate significant responsibility for public health to local governments, federal officials are more engaged in the United States) and partly to the American version of public health moralism. We also consider the renewed interest in population health, noting why, against expectations, this trend might grow more quickly in the United States than in its European counterparts.
I also learned (or relearned) from this paper the following:
1. For per capita prevention, the U.S. is a clear first in the world. (I wonder, by the way, to what extent this contributes to higher health care costs in the United States, since preventive care also can drive doctor and hospital visits.)
2. The UK and France made a deliberate decision to switch away from public health to curative medicine, after the end of World War II, when they were building out their universal coverage systems.
3. The American history with public health programs is a pretty good one, with advances coming from the anti-smoking campaign, lower speed limits, anti-drunk driving initiatives, fluoridated water, and mandatory vaccination programs.
4. The British fare poorly on various public health metrics.
5. “The US system of public health fares rather well compared to other Western nations.” On net, our population is not as anti-science as it may seem, at least not if we look at final policy results, as compared to some of our peer countries.
All in all, an interesting read.
Are generational or cohort-level changes strong?
Here is the view of Kali H. Trzesniewski and M. Brent Donnellan, in their piece “Rethinking “Generation Me”: A Study of Cohort Effects from 1976-2006”:
Social commentators have argued that changes over the last decades have coalesced to create a relatively unique generation of young people. However, using large samples of U.S. high-school seniors from 1976 to 2006 (Total N = 477,380), we found little evidence of meaningful change in egotism, self-enhancement, individualism, self-esteem, locus of control, hopelessness, happiness, life satisfaction, loneliness, antisocial behavior, time spent working or watching television, political activity, the importance of religion, and the importance of social status over the last 30 years. Today’s youth are less fearful of social problems than previous generations and they are also more cynical and less trusting. In addition, today’s youth have higher educational expectations than previous generations. However, an inspection of effect sizes provided little evidence for strong or widespread cohort-linked changes.
The pointer is from @hardsci. As he (Sanjay) notes on Twitter: “Researchers these days just don’t make cohort arguments like they used to” And here are some related results on narcissism.
The seventeenth century was a special time in Britain
The apprentice dataset, which is richest and most reliable from 1580 to 1680, tells much the same story for the seventeenth century. As we expected, the underlying shares of apprentices’ parents in industry and services are higher than in the probate dataset, but the trends move in parallel. Agriculture declines consistently over this period. Industry and services both grow substantially, with services outstripping industry. Compared to the probate data, the share of the workforce in agriculture declines more quickly, while the rate of expansion in industry is somewhat slower in the first half of the seventeenth century, although it reaches a similar level by 1660–1679. The growth in services is similar to the probate dataset. This coherence between the results from two independent sources offers a first test of the validity of our findings.
That is from a newly published and important paper by Patrick Wallis, Justin Colson, and David Chilosi, “Structural Change and Economic Growth in the British Economy before the Industrial Revolution, 1500–1800.”

The evolution of American welfare
As of 2016, only fourteen percent of single-parent households without earnings received cash assistance. However, the phase-out of participation with respect to earned income has decreased by half over this time period.

Where did Swedish schooling go wrong?
Some parts of this paper seem a priori implausible to me, and I don’t think the abstract puts the best foot forward for the paper, but these are such important issues I wanted to pass along the new piece by Magnus Henrekson and Johan Wennström. Here is the opener:
The Swedish school system suffers from profound problems with teacher recruitment and retention, knowledge decline,and grade inflation. Absenteeism is high, and psychiatric disorders have risen sharply among Swedish pupils in the last ten years. In this pioneering analysis of the consequences of combining institutionalized social constructivism with extensive marketization of education, we suggest that these problems regarding school quality are to no small extent a result of the Swedish school system’s unlikely combination of a postmodern view of truth and knowledge, the ensuing pedagogy of child-centered discovery, and market principles. Our study adds to the findings from previous attempts to study the effects of social-constructivist pedagogy in nonmarket contexts and yields the implication that caution is necessary for countries, notably the U.S., that have a tradition of social-constructivist practices in their education systems and are considering implementing or expanding market-based school reforms.
At the risk of sounding like Bryan Caplan, is schooling even effective enough for mistakes in method to be so fatal?

My Conversation with Michele Gelfand
Here is the audio and transcript, and here is the summary:
Michele Gelfand is professor of psychology at the University of Maryland and author of the just-released Rule Makers, Rule Breakers: How Tight and Loose Cultures Wire Our World. In her conversation with Tyler, Michele unpacks the concept of tight and loose cultures and more, including which variable best explains tightness, the problem with norms, whether Silicon Valley has an honor culture, the importance of theory and history in guiding research, what Donald Trump gets wrong about negotiation, why MBAs underrate management, the need to develop cultural IQ, and why mentorship should last a lifetime.
Here is one excerpt:
COWEN: As you know, it’s a common distinction in cross-cultural analysis to call some cultures individualistic and others collectivistic. How does tightness and looseness differ from that distinction? What do you pick up that, say, the work of Triandis does not?
GELFAND: Actually, Triandis is my mentor. I went to Champaign to work with him. I did a lot of research on collectivism and individualism. For a long time, that was the one dimension that we looked at in cross-cultural psychology.
It’s almost akin to, in personality psychology, only studying extroversion to the neglect of other dimensions, like neuroticism. In cross-cultural psychology, we got a little bit narrow in what we were studying. Collectivism-individualism is related to tightness but distinct.
Part of the problem we’ve had is, we’ve confounded cultures in our research. We’ve been studying East Asia, which is both tight and collectivistic, with the United States and other Western cultures, which tend to be loose and individualistic. So they have been confounded.
But when you think about the off-diagonals of that two-by-two, you can imagine cultures like Germany, Switzerland, Austria that tend to be pretty individualistic. They emphasize privacy. They’re not hugely group and family oriented, but they’re relatively tight. They have strong rules and punishments for deviance.
On the flip side, you can think about Latin American cultures — in our data, that’s Brazil or Spain — that tend to be pretty family oriented and pretty collectivistic, but they’re rather loose.
In a lot of ways, you can disentangle that variation, even if they’re related. They tend to be related about 0.4. That’s found both in modern nations and also traditional societies. At the state level, they also tend to be related but again distinct. Only in that case, it’s about 0.2 or 0.3, the correlation between tightness and collectivism.
And:
COWEN: Overrated or underrated, Staten Island?
GELFAND: [laughs] I would say probably underrated. That’s because I actually am familiar with Staten Island. We have relatives that live there. It’s probably the last undiscovered place around the city. Brooklyn has become a chichi place to live, but Staten Island has not. There’s great delis there. I’ve spent some time there.
And:
COWEN: Putting aside your political views, but just if you observe Donald Trump as a negotiator — as a psychologist, what strikes you?
GELFAND: Donald Trump has a very classic negotiation style. It’s a distributive negotiation style. It’s a win-lose style. It works in certain contexts, especially contexts where there’s one issue or when there’s very little expected future interaction.
What Donald Trump does is, he takes that style to international [laughs] politics where these contexts, the structure of these situations is very different. There’s usually many issues at the table. There’s expected future interaction…His style is really mismatched with the context that he’s in.
Many of the best parts are at or near the end, so do read or listen all the way through. And you can buy Michele’s book here.
Buchanan and Wagner were right, fiscal policy is fairly pro-cyclical
Our study reveals a mixed fiscal scenery, where more than half of the countries are recently characterized by limited fiscal space, and fiscal policy is either acyclical or procyclical (though not as high the level of 1980s), notably post-GFC becoming even more procyclical in government spending when accounting for net acquisition of nonfinancial assets and capital expenditure (spending components do matter).

Chris Blattman is becoming more skeptical of cash transfers
His new paper is with Nathan Fiala and Sebastian Martinez:
In 2008, Uganda granted hundreds of small groups $400/person to help members start individual skilled trades. Four years on, an experimental evaluation found grants raised earnings by 38% (Blattman, Fiala, Martinez 2014). We return after 9 years to find these start-up grants acted more as a kick-start than a lift out of poverty. Grantees’ investment leveled off; controls eventually increased their incomes through business and casual labor; and so both groups converged in employment, earnings, and consumption. Grants had lasting impacts on assets, skilled work, and possibly child health, but had little effect on mortality, fertility, health or education.
And here is my earlier Conversation with Chris Blattman, in which a similar result is discussed.
And what do the investors think?
We survey a representative sample of U.S. individuals about how well leading academic theories describe their financial beliefs and decisions. We find substantial support for many factors hypothesized to affect portfolio equity share, particularly background risk, investment horizon, rare disasters, transactional factors, and fixed costs of stock market participation. Individuals tend to believe that past mutual fund performance is a good signal of stock-picking skill, actively managed funds do not suffer from diseconomies of scale, value stocks are safer and do not have higher expected returns, and high-momentum stocks are riskier and do have higher expected returns.
That is from a new paper by James J. Choi and Adriana Z. Robertson.
Peer review is becoming tougher to achieve
Scientists in developed countries provide nearly three times as many peer reviews per paper submitted as researchers in emerging nations, according to the largest ever survey of the practice.
The report — which surveyed more than 11,000 researchers worldwide — also finds a growing “reviewer fatigue”, with editors having to invite more reviewers to get each review done. The number rose from 1.9 invitations in 2013 to 2.4 in 2017…
The report notes that finding peer reviewers is becoming harder, even as the overall volume of publications rises globally (see ‘Is reviewer fatigue setting in?’).
File under “the cost disease strikes back.” Furthermore, it seems increasingly obvious that a lot of lesser journals just don’t matter, and that may discourage prospective referees from putting in the effort. And note:
In 2013–17, the United States contributed nearly 33% of peer reviews, and published 25.4% of articles worldwide. By contrast, emerging nations did 19% of peer reviews, and published 29% of all articles.
China stood out — the country accounted for 13.8% of scientific articles during the period, but did only 8.8% of reviews.

American competitive democracy survives
Most elections in the United States are not close, which has raised concerns among social scientists and reform advocates about the vibrancy of American democracy. In this paper, we demonstrate that while individual elections are often uncompetitive, hierarchical, temporal, and geographic variation in the locus of competition results in most of the country regularly experiencing close elections. In the four-cycle period between 2006 and 2012, 89% of Americans were in a highly competitive jurisdiction for at least one office. Since 1914, about half the states have never gone more than four election cycles without a close statewide contest. More Americans witness competition than citizens of Canada or the UK, other nations with SMSP-based systems. The dispersed competition we find also results in nearly all Americans being represented by both political parties for different offices.

Does the “extractive institutions” hypothesis fail the empirical test?
The title of this paper is “Colonial Revenue Extraction and Modern Day Government Quality in the British Empire,” and it is by Rasmus Broms. Here goes:
The relationship between the extent of government revenue a government collects, primarily in the form of taxation, and its overall quality has increasingly been identified as a key factor for successful state building, good institutions, and—by extension—general development. Initially deriving from historical research on Western Europe, this process is expected to unfold slowly over time. This study tests the claim that more extensive revenue collection has long-lasting and positive consequences for government quality in a developmental setting. Using fiscal records from British colonies, results from cross-colony/country regression analyses reveal that higher colonial income-adjusted revenue levels during the early twentieth century can be linked to higher government quality today. This relationship is substantial and robust to several specifications of both colonial revenue and modern day government quality, and remains significant under control for a range of rivaling explanations. The results support the notion that the current institutional success of former colonies can be traced back to the extent of historical revenue extraction.

The rise of the Swedish Democrats
There is a new research paper on this topic, from Ernesto Dal Bo, Frederico Finan, Olle Folke, Torsten Persson, and Johanna Rickne:
We study the rise of the Sweden Democrats, a radical-right party that rose from negligible size in 2002 to Sweden’s third largest party in 2014…We take a starting point in two key economic events: (i) a series of policy reforms in 2006-2011 that significantly widened the disposable-income gap between “insiders” and “outsiders” in the labor market, and (ii) the financial-crisis recession that doubled the job-loss risk for “vulnerable” vs “secure” insiders. On the supply side, the Sweden Democrats over-represent both losing groups relative to the population, whereas all other parties under-represent them, results which also hold when we disaggregate across time, subgroups, and municipalities. On the demand side, the local increase in the insider-outsider income gap, as well as the share of vulnerable insiders, are systematically associated with larger electoral gains for the Sweden Democrats. These findings can be given a citizen-candidate interpretation: economic losers (as we demonstrate) decrease their trust in established parties and institutions.
Is it being an economic loser that makes you support the Sweden Democrats, or simply observing a lot of economic losers around you, the latter having been the case for Donald Trump’s support? This Twitter thread gives some key pictures from the paper and summary of results.
Death, Trauma and God: The Effect of Military Deployments on Religiosity
Learning to cope with man’s mortality is central to the teachings of the world’s major religions. However, very little is known about the impact of life-and-death trauma on religiosity. This study exploits a natural experiment in military deployments to estimate the causal effect of traumatic shocks on religiosity. We find that combat assignment is associated with a substantial increase in the probability that a serviceman subsequently attends religious services regularly and engages in private prayer. Combat-induced increases in religiosity are largest for enlisted servicemen, those under age 25, and servicemen wounded in combat. The physical and psychological burdens of war, as well as the presence of military chaplains in combat zones, emerge as possible mechanisms.

The Economic Effects of Social Networks: Evidence from the Housing Market
That is by Michael Bailey, Ruiqing Cao, Theresa Kuchler, and Johannes Stroebel¶, there is a demonstration effect in consumption, namely you are more likely to buy a house if your friends did well buying homes. Here is from the working paper version:
We show how data from online social networking services can help researchers better understand the effects of social interactions on economic decision making. We use anonymized data from Facebook, the world’s largest online social network, to first explore heterogeneity in the structure of individuals’ social networks. We then exploit the rich variation in the data to analyze the effects of social interactions on housing market investments. To do this, we combine the social network information with housing transaction data. Variation in the geographic dispersion of social networks, combined with time-varying regional house price changes, induces heterogeneity in the house price experiences of different individuals’ friends. We show that individuals whose geographically distant friends experienced larger recent house price increases are more likely to transition from renting to owning. They also buy larger houses and pay more for a given house. Similarly, when homeowners’ friends experience less positive house price changes, these homeowners are more likely to become renters, and more likely to sell their property at a lower price. We find that these relationships are driven by the effects of social interactions on individuals’ housing market expectations. Survey data show that individuals whose geographically distant friends experienced larger recent house price increases consider local property a more attractive investment, with bigger effects for individuals who regularly discuss such investments with their friends.
