We investigate how the gender gap in confidence affects the views that evaluators (e.g., employers) hold about men and women. We find the confidence gap is contagious, causing evaluators to form overly pessimistic beliefs about women. This result arises even though the confidence gap is expected and even though the confidence gap shouldn’t be contagious […] The post The Gender Gap in Confidence: Expected...

Both rightists and leftists assume that the U.S. spends far lower to combat social problems (poverty, healthcare, education) than peer nations, but that is not true. pic.twitter.com/CXdVDNWb6p — David (@Data_David1) February 18, 2024 Here Robin Hanson notes that social spending as a percent of gdp tends to rise almost universally: Key question: will these trends […] The post I am tired of making this...

That is the topic of my latest Bloomberg column, here is one excerpt: The human and economic costs of recessions are deep and well-documented. They can also have real health benefits, however, and seldom are they expressed so starkly as in this sentence in a new paper from the National Bureau of Economic Research: “The Great Recession provided one in twenty-five 55-year-olds […] The post Do recessions benefit our health? appeared...

WEF 2002: The world could face lithium shortages by 2025, the International Energy Agency (IEA) says, while Credit Suisse thinks demand could treble between 2020 and 2025, meaning “supply would be stretched”.

That is the topic of my latest Bloomberg column, here is one bit: California’s highest income tax rate is 13.3%. That is in addition to a top federal tax rate of 37%. California also has a state sales tax rate of 7.25%, and many localities impose a smaller sales tax. So if a wealthy person earns and […] The post The California tax burden is driving...

Shanhong Luo, a professor at Fayetteville State University, studies the factors behind attraction between romantic partners, including the norms that govern relationships.

Science seems like a public good; in theory, ideas are non-rivalrous and non-excludable. But the closer we look at how ideas actually spread and are used in the world, the less they seem like public goods. As I am fond of pointing out, Thomas Keller wrote a literal recipe book for the dishes he served […] The post Is Science a Public Good? appeared...

We measure college graduate quality—the average human capital of a college’s graduates—for graduates from 2,800 colleges in 48 countries. Graduates of colleges in the richest countries have 50% more human capital than graduates of colleges in the poorest countries. Migration reinforces these differences: emigrants from poorer countries are highly positively selected on human capital. Finally, […] The post The Global Distribution of College Graduate...

In this study, we propose a novel approach to detect supply-side media bias, independent of external factors like ownership or editors’ ideological leanings. Analyzing over 100,000 articles from The New York Times (NYT) and The Wall Street Journal (WSJ), complemented by data from 22 million tweets, we assess the factors influencing article duration on their […] The post New data on media bias appeared...

From a recent Jacob Light paper: In an era of rapid technological and social change, do universities adapt enough to play their important role in creating knowledge? To examine university adaptation, I extracted the information contained in the course catalogs of over 450 US universities spanning two decades (2000-2022). When there are changes in student […] The post Student Demand and the Supply of...

The key insight is that women have always been more [economically] left-wing than men, but that women were also more religious (both vs today and vs men) and that this was a moderating force against those left-wing views. With religion in retreat, those views now take voice. pic.twitter.com/Ed3GJyHhap — John Burn-Murdoch (@jburnmurdoch) February 2, 2024 The post Religion and the ideological gender gap appeared...

Greg Clark may well be the most important social scientist of the 21st century. His use of historical data informed by evolutionary theory and genetics is a unique contribution to social science with important and challenging results. Clark’s latest paper (with Neil Cummins) makes a simple but striking point. If the primary systematic determinant of […] The post Matriline versus Patriline: Social Mobility in...

No, but they did get him some votes there: We study the economic and political consequences of the 2018-2019 trade war between the United States, China and other US trade partners at the detailed geographic level, exploiting measures of local exposure to US import tariffs, foreign retaliatory tariffs, and US compensation programs. The trade-war has […] The post Did the Trump tariffs help the...

Since the mapping of the human genome in 2004, biologists have demonstrated genetic links to the expression of several income-enhancing physical traits. To illustrate how heredity produces intergenerational economic effects, this study uses one trait, beauty, to infer the extent to which parents’ physical characteristics transmit inequality across generations. Analyses of a large-scale longitudinal dataset […] The post Hot parents, richer kids? appeared first...

Published in the journal Conflict and Health last April, the report suggests that the world’s deadliest humanitarian crisis in 2022 was not in Afghanistan, Ukraine, or other places featured regularly in the news — but in CAR.

Here is one interesting hypothesis: Despite the persistence of anti-Black racism, White Americans report feeling worse off than Black Americans. We suggest that some White Americans may report low well-being despite high group-level status because of perceptions that they are falling behind their in-group. Using census-based quota sampling, we measured status comparisons and health among […] The post Who feels the pinch of status...

There is a new paper on this topic, with what seems to be very good data: This paper examines the relationship between downward nominal wage rigidity and employment outcomes using linked employer-employee data.
