A feature of many insurance markets is that they combine vertical differentiation (all consumers prefer high to low-coverage policies) and adverse selection (high cost customers prefer high-coverage plans). Building on Novshek and Sonnenschein (1978) and Azevedo and Gottlieb (2017), this paper...

Abstract This paper extends the Becker (1968)-Ehrlich (1973) model of crime to allow for government transfers. Using the Shapiro and Stiglitz (1984) model, it is shown that one can view deterrence as a tax on (criminal) labor supply. That in turn allows an integration of a crime model with a...

We introduce a model of the admissions process based upon standard agency theory and explore its implications with economics PhD admissions data from 2013-2019. We show that a subjective score that aggregates subjective ratings and recommendation letter features plays a more important role in...

The purpose of this essay is to discuss two approaches to inference, and how "human capital" can provide a way to combine them. The first approach, ubiquitous in economics, is based upon the Rubin/Holland potential outcomes model and relies upon randomized treatment to measure the causal effect...

Treatment for depression is complex, requiring decisions that may involve tradeoffs between exploiting treatments with the highest expected value or experimenting with treatments with higher possible payoffs. Using patient claims data, we show that among skilled doctors, using a broader...

Friedman (1955) argued that giving parents freedom to choose schools would improve education. His argument was simple and compelling because it extended results from markets for consumer goods to education. We review the evidence, which yields surprisingly mixed results on Friedman's prediction....

Although conflicts typically lead to a waste of resources, organizations may still benefit from a corporate culture that tolerates or even encourages conflicts. The reason is that coordinated conflicts may help to enforce informal contracts and foster cooperation. In this paper we report results...

Anecdotal evidence often points to aging as a cause for reduced work performance. This paper provides empirical evidence on this issue in a context where performance is measurable and there is variation in mandatory retirement policies: U.S. state supreme courts. We find that introducing...

Around 1875 the U.S. had none of the world's leading research universities; today, it accounts for the majority of the top-ranked. Many observers cite events surrounding World War II as the source of this reversal. We present evidence that U.S. research universities had surpassed most countries'...

Contract law and the economics of contract have, for the most part, developed independently of each other. In this essay, we briefly review the notion of a contract from the perspective of lawyer, and then use this framework to organize the economics literature on contract. The review thus...
