We evaluate the consequences of prosecuting HIV+ people who expose others to the risk of infection. We show that the effect of aggressive prosecutions on the spread of HIV is a priori ambiguous. Aggressive prosecutions tax risky behavior and thus deter unsafe sex and limit the number of sexual...

In this chapter, we discuss field experiments in surveys that are conducted with the purpose of learning about expectation formation and the link between expectations and behavior. We begin by reviewing the rationale for conducting experiments within surveys, rather than just relying on...

Many decisions - such as what educational or career path to pursue - are dynamic in nature, with individuals receiving feedback at one point in time and making decisions later. Using a controlled experiment, with two sessions one week apart, we analyze the dynamic effects of feedback on beliefs...

We study how large shocks impact individuals' skilling decisions using data from the largest online learning platform in Saudi Arabia. The onset of the COVID-19 pandemic brought about a massive increase in online skilling, and demand shifted towards courses that offered skills, such as telework,...

How important are social constraints and information gaps in explaining the low rates of female labor force participation (FLFP) in conservative societies that are undergoing social change? To answer this question, we conducted a field experiment embedded in a survey of female university...

Using administrative data from a large 4-year public university, we show that male students are 18.6 percent more likely than female students to receive favorable grade changes initiated by instructors. These gender differences cannot be explained by observable characteristics of the students,...

In this paper, we estimate a rich model of college major choice using a panel of experimentally-derived data. Our estimation strategy combines two types of data: data on self-reported beliefs about future earnings from potential human capital decisions and survey-based measures of risk and time...

We investigate the role of information frictions in the US labor market using a new nationally representative panel dataset on individuals' labor market expectations and realizations. We find that expectations about future job offers are, on average, highly predictive of actual outcomes. Despite...

This article reviews the recent literature on the determinants of college major choices. We first highlight long-term trends and persistent differences in college major choices by gender, race, and family background. We then review the existing research in six key areas: expected earnings and...

In order to understand the impact of the COVID-19 pandemic on higher education, we surveyed approximately 1,500 students at one of the largest public institutions in the United States using an instrument designed to recover the causal impact of the pandemic on students' current and expected...
