A country's exports rise when its leadership is approved by other countries. I show this using a standard gravity model of bilateral exports, a panel of data from 2006 through 2017, and an annual Gallup survey which asks people in up to 157 countries whether they approve of the job performance...

We study the macroeconomic consequences of tariffs. We estimate impulse response functions from local projections using a panel of annual data that spans 151 countries over 1963-2014. We find that tariff increases lead, in the medium term, to economically and statistically significant declines...

This paper explains upward job mobility and observed patterns of unemployment by skill as an economy recovers from a recession. Skilled unemployment is due to rational waiting by workers looking for long-term jobs when there is a "lock-in" effect. Lock-in occurs if the conditions in the labor...

Costs of attention, while central to choice behavior, have proven hard to measure. We introduce a simple method of recovering them from choice data. Our recovery method rests on the observation that costs of attention play precisely the same role in consumer choice as do a competitive firm's...

We model agents who get utility from their beliefs and therefore interpret information optimistically. They may exhibit several biases observed in psychological studies such as optimism, procrastination, confirmation bias, polarization, and the endowment effect. In some formulations, they...

We study whether the effects of monetary policy are dependent on the demographic structure of the population. We exploit cross-sectional variation in the response of US states to an identified monetary policy shock. We find that there are three distinct age groups. In response to an increase in...

This paper is motivated by a set of cross-country observations on growth, structural transformation, and investment rates in a large sample of countries. We observe a hump-shaped relationship between a country's investment rate and its level of development, both within countries over time and...

This paper examines theory and evidence from recent studies into the contributions to economic growth of expenditure on education and on research and development. Investment in human capital has fundamentally different economic attributes to physical investment - exhibiting complementarity,...

We complete the study of comparative statics initiated in Caplin and Leahy [2010], which introduced a new mathematical apparatus for understanding NTU allocation markets, as such covering the housing market and other markets for large indivisible goods. We introduce homotopy methods to...
