A new study from the University of Alabama in Huntsville addresses the question of how much the Urban Heat Island (UHI) effect is responsible for the higher temperatures at weather stations across the world. Dr. Roy Spencer and Dr. John Christy have spent several years developing a novel method that quantifies, for the first time, the average UHI warming effects related to population density. Their finding: no less than 65% of “runaway global warming” is not caused by our emissions of carbon dioxide, but by the urbanization of the world.

TweetNicholas Bloom, Kyle Handley, André Kurmann, and Philip A. Luck revisit the “China Shock.” Two slices: Our research investigates the extent to which the opposing trends in manufacturing and services job growth are related. Our findings reveal that local labor markets more exposed to Chinese import competition experienced larger manufacturing job losses. But these losses…

I’ve written a couple of times about information interventions designed to attract more female students to study economics (see here and here). The results have generally been disappointing. That shouldn’t be too much of a surprise. If it was really simple to get people to change their behaviour with information, then advertising would be far…

Jon Hartley serves as interlocutor in “Revisiting Empirical Macroeconomics with Robert Barro” (Hoover Institution, Capitalism and Freedom Podcast, March 25, 2025, audio and transcript available). Here are a few of the comments from Barro that especially caught my eye. One basic question in economics is about “the multiplier”–that is, how much will an increase in…

This short note shows that accounting for capital adjustment is critical when analyzing the long-run effects of trade wars on real wages and consumption. The reason is that trade wars increase the relative price between investment goods and labor by taxing imported investment goods and their inputs. This price shift depresses capital demand, shrinks the […]

This was the post I was planning to write this morning to mark Orr’s final day. That said, if the underlying events – deliberate attempts to mislead Parliament – were Orr’s doing, the post is more about the apparent uselessness of Parliament (specifically the Finance and Expenditure Committee) in holding him and the rest of […]

This paper examines the effects of the Big Five personality traits on labor market outcomes and gender wage gaps using a job search and bargaining model with parameters that vary at the individual level. The analysis, based on German panel data, reveals that both cognitive and noncognitive traits significantly influence wages and employment outcomes. Higher […]

The chronometer, one of the greatest inventions of the modern era, allowed for the first time for the precise measurement of longitude at sea. We examine the impact of this innovation on navigation and urbanization. Our identification strategy leverages the fact that the navigational benefits provided by the chronometer varied across different sea regions depending […]

How can I not link to a new Sam Peltzman piece on such a topic? Here goes: Since 1972, the General Social Survey has periodically asked whether people are happy with Yes, Maybe or No type answers. Here I use a net “happiness” measure, which is percentage Yes less percentage No with Maybe treated as […]

In the last decade, large financial institutions in the United States have purchased hundreds of thousands of homes and converted them to rentals. This paper studies the welfare consequences of institutional ownership of single-family housing. We build an equilibrium model of the housing market with two sectors: rental and homeownership. The model captures two key…

Economist: In America returns are especially large in computer science and in engineering. They are slightly smaller in other science subjects, in part because an undergraduate degree in these already bumps up salaries by quite a lot. Teachers who bag graduate degrees in education tend to earn more, even if wages for the profession as…
