We use de-identified data from California personal income tax returns to measure the frequency and nature of independent contracting and self-employment work in California. We identify this work by the presence of a Schedule C on the tax return and/or the receipt of a Form 1099 information...

We study a unique grading policy at a large US public university allowing students to mask their letter grades into a "Pass", after having observed their original grade. Using administrative transcript records, we find that female students are substantially less likely to mask their grades than...

We evaluate the extent to which small businesses maintain an online presence, looking at restaurant listings on a major online review platform. While the majority of restaurants have an online presence, we find that roughly 18 percent in our sample have no presence as of the end of 2017, despite...

We investigate the role of evidence-based information in shaping individuals' preferences for trade policies through a series of survey experiments that contain randomized information treatments. Each treatment provides a concise statement of economics research findings on how openness to trade...

We exploit recent decades of US state-level reforms to the generosity of workers' compensation programs to estimate the associated moral hazard, utilizing an event- study design and analyzing 9 separate reform categories. The reforms vary - some affecting benefit size, some the probability of...

Why do wars occur? We exploit a natural experiment to test the longstanding hypothesis that leaders declare war because they fail to internalize the associated costs. We test this moral hazard theory of conflict by compiling data on the 9,210 children of 3,693 US legislators who served in the...

This paper considers functions of contracting other than the protection of relationship-specific investments and the provision of marginal incentives, and applies the theory to explain variation in the form of compensation of over-the-road truck drivers in the U.S. Specifically, we argue that...
