Equal pay laws increasingly require that workers with different group identities doing “similar” work are paid equal wages within firm. We study such “equal pay for similar work” (EPSW) policies theoretically and test our models’ predictions empirically using evidence from a 2009 gender-based Chilean EPSW. Under EPSW, firms segregate their workforce by gender. When there are more men than women i…

We investigate the origins and implications of zero-sum thinking: the belief that gains for one individual or group tend to come at the cost of others. Using a new survey of 20,400 US residents, we measure zero-sum thinking, political preferences, policy views, and a rich array of ancestral information spanning four generations. We find that a more zero-sum mindset is strongly associated with mor…

We assemble a new dataset spanning 150 years and 60 countries to study the economic toll of war. A war of average intensity is associated with an output drop of close to 10 percent in the war-site economy, while consumer prices rise by approximately 20 percent. The capital stock, total factor productivity, and equity returns all decline sharply. The economic ramifications of war are not confined …

We consider an economy in which long-lived experts are matched with short-lived clients. Experts choose the type of client with whom they match, unobserved by the market. The interaction outcome depends on both the expert’s and the client’s type. We study the effects of supplying information about otherwise unobservable outcomes, such as “medical report cards,” to help clients identify better exp…

We propose a novel identification strategy to isolate exogenous immigration shocks across US counties, by interacting quasi-random variations in the composition of ancestry across counties with the contemporaneous inflow of migrants from different countries. We show a positive causal impact of immigration on local innovation and wages at the five-year horizon. The positive dynamic impact of immig…

This paper estimates the effects of improving public transit infrastructure on city structure and welfare. It develops a quantitative urban model with multiple worker groups and transit modes, and derives a special case yielding sufficient statistics for aggregate welfare in a broad class of models. The paper estimates reduced-form elasticities to implement the approach using data spanning constr…

This paper studies the efficiency of self-enforced relational agreements, a common solution to contracting frictions, when sellers have market power and contracts cannot be externally enforced. To this end, I develop a dynamic contracting model with limited enforcement in which buyers can default on their trade credit debt and estimate it using a novel dataset from the Ecuadorian manufacturing su…

We assess whether men and women are treated differently when presenting their economics research. We collected data across thousands of seminars, job market talks, and conference presentations, leveraging human judgment and audio-processing algorithms to measure the number, tone, and type of interruptions. Within a seminar series, women are interrupted more than men. This holds when controlling f…

Captive finance subsidiaries create a channel for trade policy to affect consumer credit. Examining the impact of the Trump administration’s metal tariffs on captive automobile lenders, we find that consumers received higher interest rates from captive lenders after the tariffs relative to unaffected noncaptive lenders. Further, we document a disparate impact on low-income borrowers and in areas …

Principal-agent problems often extend beyond what can be directly addressed through conventional incentive arrangements. We examine a context where physicians are likely under-incentivized to minimize total medical costs until their private financial interests align with those of patients. Leveraging novel data on physician ownership of ambulatory surgery centers——that is, same-day facilities——we…

We argue that consumer credit spreads matter for household choices and that time-varying spreads have important distributional consequences. Studying Danish household data, we show that consumer credit spreads have heterogeneous impact on asset dynamics and consumption choices across the wealth distribution and that time-varying spreads induce a countercyclical marginal propensity to consume. We …

We study the effects of intensifying competition for contracts in the context of US Defense procurement. Leveraging a discontinuous regulation that mandates agencies to publicize certain contract opportunities, we document that expanding the set of bidders reduces award prices but deteriorates post-award performance in terms of cost overruns and delays. We develop and estimate an auction model wi…

This paper investigates a sequential social learning problem in which individuals face ambiguity about others’ signal structures and have max-min expected utility preferences, thereby exhibiting ambiguity aversion. Unlike previous findings, which suggest that learning outcomes depend on the specifics of the learning environment, this study establishes information cascades as a robust outcome unde…

Using new methods, we measure the intensities of higher-order risk preferences (prudence and temperance) in an incentivized experiment with 658 adolescents. Aligned with theory, we find that higher-order risk preferences are strongly related to field behavior, including prevention, health, addictive behavior, and financial decision-making. Most importantly, we show that ignoring prudence and temp…

We develop a leverage theory of tying in markets with network effects. When a monopolist in one market cannot perfectly extract surplus from consumers, tying can be a mechanism through which unexploited consumer surplus is used as a demand-side leverage to create a “quasi-installed base” advantage in another market characterized by network effects. Our mechanism does not require any precommitment…

Many employers link wages at establishments outside of the home region to the level at headquarters. We show this using new data on 1,200 multinationals’ establishments across the world and linked employee-level data on their establishments in Brazil. Headquarters wage changes arising from minimum wage and exchange rate shocks are partially transmitted to workers employed in the same position abr…

We construct a public atlas of mean outcomes in adulthood by childhood census tract. Outcomes vary sharply across neighborhoods: For children whose parents earn $27,000, the standard deviation of mean household income in adulthood is $10,420 across tracts within counties. Only half the variation in outcomes is explained by traditional measures of neighborhood opportunity like poverty rates. Exper…

Individuals might experience negative utility from not consuming a popular product. With such externalities to nonusers, standard consumer surplus measures, which take aggregate consumption as given, fail to appropriately capture consumer welfare. We propose an approach to account for these externalities and apply it to estimate consumer welfare from two social media platforms: TikTok and Instagr…

Using field and laboratory experiments, we demonstrate that the complexity of incentive schemes and worker bounded rationality can affect effort provision. This is because some attributes of the incentives become opaque; that is, workers do not take them into account. In our setting, workers overprovide effort relative to a fully rational benchmark, improving efficiency. We identify contract feat…

Wage rigidity is an important explanation for unemployment fluctuations. In benchmark models wages for new hires are key, but there is limited evidence on this margin. We use wages posted on vacancies, with job and establishment information, to measure the wage for new hires. We show that our measure of the wage for new hires is rigid downward and flexible upward, in two steps. First, wages chang…
