From a recent paper: We bring novel data to bear on these questions, presenting the largest empirical study of private security to date.

Thus, approximately 1 out of 7 people who I classify as a Latter-day Saint attends [religious service] weekly. And: However, only 5% of Americans attend services “weekly”, far fewer than the ~22% who report to do so in surveys.

There are pronounced racial, ethnic, and gender gaps in income in the U.S. We investigate whether these correspond with differences in competitiveness, risk tolerance, and confidence relative to performance in a large, stratified sample of the U.S. prime-age population. We find substantial differences in all three traits across Black, Hispanic, and White males and females. […] The post Disparities in psychological traits and incomes...

The country, which is a bit bigger than Maryland, not only accomplished this feat but also has become the world’s second largest exporter of agricultural products by value behind the United States.

Income Growth Over Five Generations of Americans,” by Kevin Corrinth and Jeff Larrimore.  Here is the abstract: We find that each of the past four generations of Americans was better off than the previous one, using a post-tax, post-transfer income measure constructed annually from 1963-2022 based […] The post New results on intergenerational progress appeared...

Economics research has largely overlooked non-binary individuals. We aim to jump-start the literature by providing data on several economically-important beliefs and preferences. Among many results, non-binary individuals report more gender-based discrimination and express different career and life aspirations, including less desire for children. Anti-non-binary sentiment is stronger than anti-LGBT sentiment, and strongest among men. Non-binary […] The post Non-binary gender economics appeared first on...

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...

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.
