Earnings Inequality and the Minimum Wage: Evidence from Brazil

By Niklas Engbom and Christian Moser

American Economic Review, December 2022

Increases in the minimum wage can substantially reduce earnings inequality. To demonstrate this, we combine administrative and survey data with an equilibrium model of the Brazilian labor market. We find that a 128 percent increase in the real minimum wag...

Interaction, Stereotypes, and Performance: Evidence from South Africa

By Lucia Corno, Eliana La Ferrara, and Justine Burns

American Economic Review, December 2022

We exploit a policy designed to randomly allocate roommates in a large South African university to investigate whether interracial interaction affects stereotypes, attitudes and performance. Using implicit association tests, we find that living with a roo...

Dynamic Matching in Overloaded Waiting Lists

By Jacob D. Leshno

American Economic Review, December 2022

This paper introduces a stylized model to capture distinctive features of waiting list allocation mechanisms. First, agents choose among items with associated expected wait times. Waiting times serve a similar role to that of monetary prices in directing ...

Optimality of Matched-Pair Designs in Randomized Controlled Trials

By Yuehao Bai

American Economic Review, December 2022

In randomized controlled trials, treatment is often assigned by stratified randomization. I show that among all stratified randomization schemes that treat all units with probability one half, a certain matched-pair design achieves the maximum statistical...

Convex Supply Curves

By Christoph E. Boehm and Nitya Pandalai-Nayar

American Economic Review, December 2022

We provide evidence that industries' supply curves are convex. To guide our empirical analysis, we develop a model in which capacity constraints at the firm level generate supply curves that are convex in logs at the industry level. The industry's capacit...

Trading on Sunspots

By Boyan Jovanovic and Viktor Tsyrennikov

American Economic Review, December 2022

In a model with multiple Pareto-ranked equilibria, we show that the set of equilibria shrinks if we allow trade in assets that pay based on the realization of a sunspot acting as an equilibrium-selection device. When the probability of a low-output outcom...

Learning from Manipulable Signals

By Mehmet Ekmekci, Leandro Gorno, Lucas Maestri, Jian Sun, and Dong Wei

American Economic Review, December 2022

We study a dynamic stopping game between a principal and an agent. The principal gradually learns about the agent's private type from a noisy performance measure that can be manipulated by the agent via a costly and hidden action. We fully characterize th...

Dynamic Amnesty Programs

By Sam Kapon

American Economic Review, December 2022

A regulator faces a stream of agents engaged in crimes with stochastic returns. The regulator designs an amnesty program, committing to a time path of punishments for criminals who report their crimes. In an optimal program, time variation in the returns ...

Family Heterogeneity, Human Capital Investment, and College Attainment

By Adam Blandin and Christopher Herrington

American Economic Journal: Macroeconomics, October 2022

From 1995 to 2015 the aggregate US college completion rate increased almost 50 percent, but completion trends differed markedly by family background. We consider whether changing college preparedness contributed to growth in aggregate completion and diffe...

Wage Cyclicality and Labor Market Sorting

By Ana Figueiredo

American Economic Review: Insights, December 2022

This paper uses a measure of skill mismatch to separate wage flexibility from confounding variation in wages driven by differences in job quality over the business cycle. I first show that the high cyclicality of job switchers' wages goes beyond cyclical ...

Using Neural Networks to Predict Microspatial Economic Growth

By Arman Khachiyan, Anthony Thomas, Huye Zhou, Gordon Hanson, Alex Cloninger, Tajana Rosing, and Amit K. Khandelwal

American Economic Review: Insights, December 2022

We apply deep learning to daytime satellite imagery to predict changes in income and population at high spatial resolution in US data. For grid cells with lateral dimensions of 1.2 km and 2.4 km (where the average US county has dimension of 51.9 km), our ...

The Limits of Multiproduct Price Discrimination

By Nima Haghpanah and Ron Siegel

American Economic Review: Insights, December 2022

We consider a multiproduct seller who has access to information about consumer preferences that he can use for second- and third-degree price discrimination. We characterize markets for which such information can lead to the efficient allocation with cons...
