AbstractThis study proposes an econometric framework to interpret and empirically decompose the difference between instrumental variables (IV) and ordinary least squares (OLS) estimates given by a linear regression model when the true causal effects of…
AbstractWe propose methods to estimate and make inferences on conditional quantile processes for models with both nonparametric and (locally or globally) linear components. We derive their asymptotic properties, optimal bandwidths, and uniform confiden…
AbstractWe measure trends in affective polarization in twelve OECD countries over the past four decades. According to our baseline estimates, the United States experienced the largest increase in polarization over this period. Five countries experience…
AbstractThis paper develops a novel dataset of weekly economic conditions indices for the 50 U.S. states going back to 1987 based on mixed-frequency dynamic factor models with weekly, monthly, and quarterly variables that cover multiple dimensions of s…
AbstractThis paper presents experimental evidence on the impact of a role model on secondary school students’ exam performance in Uganda. Students were individually randomized to see either a movie featuring a female role model, Queen of Katwe, or to s…
AbstractWe estimate the effects of student loan access on educational attainment and labor market returns in New Zealand. We exploit the introduction of a national policy mandating a 50% pass rate for student loan renewals using a regression discontinu…
AbstractWe use novel survey data to study firms’ inventory contracts. We document facts about the usage of purchase and sale contracts. We find that firms purchase and sell inventory through three contractual arrangements: fixed price and quantity, fix…
AbstractWe introduce two empirical strategies harnessing the randomness in school assignment mechanisms to measure school value-added. The first estimator controls for the probability of school assignment, treating take-up as ignorable. We test this as…
AbstractIf overcrowding harms health care quality, the impacts of encouraging more people to use services are not obvious. Impacts will depend on whether marginal entrants benefit and whether they benefit enough to offset the congestion externalities i…
AbstractThis paper studies the executive-legislative exchange of centrally allocated benefits (jam) for legislative support in Colombia using data from road building projects, legislative roll-call votes, and a leaked database which uncovered the assig…
