摘要：Export promotion at the extensive margin is a key concern ofgovernments. We develop measures of how far firms in origin sectors arefrom break-even entry in destination markets. The measure is based on Al-most Ideal gravity featuring heterogeneous price and income elasticities.Tobit estimation of 2006 trade flows for 75 countries and 25 sectors gener-ates latent trade bias (LTB)-the latent (projected) trade share of nonpart-ners minus the as-if-frictionless trade share. Explained LTB variance d...

摘要：We analyze the impact of Covid-19 on productivity using datafrom an innovative monthly firm survey that asks for quantitative impactsof Covid-19 on inputs and outputs. We find thattotal factor productiv-ity (TFP) fell by up to 6% during 2020-2021. The overall impact com-bined large reductions in 'within-firm' productivity, with offsetting posi-tive 'between-firm' effects as less productive sectors, and less productive firms within them, contracted. Despite these large pandemic effects, firms'p...

摘要：We study the removal of information from a market, such as a job-applicant screening tool. We characterize how removal harms groups with relative advantage in that information: typically those for whom the banned information is most precise relative to alternative signals. We illustrate this using recent bans on employers' use of credit report data. Bans decrease job-finding rates for Black job-seekers by 3 percentage points and increase involuntary separations for Black new hires by 4 percent...

摘要：Using over 11,000 unlicensed loans to over 1,000 borrowers inSingapore, we provide basic information about an understudied market:illegal moneylending. Borrowers and lenders interact frequently and relyprimarily on relational contracts to enforce their agreements. Borrowershave high discount rates, often have gambling and/or substance abuse prob-lems, and often repay late. While lenders sometimes resort to nonfinancialpunishments, the primary cost of late repayment is the compounding of avery ...

摘要：In this paper, we investigate the economic consequences of massshootings. We find that shootings have negative effects on targeted coun-ties' economies. Estimates using three different comparison groups yieldsimilar results. Examining the mechanisms, we find that residents of tar-geted areas: (i) develop pessimistic views of financial and local businessconditions; and (ii) are more likely to report poor mental health, whichhinders usual activities such as work, suggesting that shootings lead t...

摘要：We provide a method to track the active prevalence of COVID-19 in real time, correcting for time-varying sample selection in symptom-based testing data and incomplete tracking of recovered cases and fatalities. Our method only requires publicly available data on positive testing rates in combination with one parameter, which we estimate based on a representative randomized sample of nearly 10,000 individuals tested in Utah in May and June 2020. We validate our method using external studies in ...

摘要：Firms success in international markets depends on their product's quality, prices, markups, and marginal cost. However, causally identified empirical evidence for the effect of trade policies that address nontariff barriers on these mechanisms is rare. To fill this gap, we exploit a quasinatural experiment in Denmark and examine the effects of an export support policy aimed at reducing nontariff barriers to trade. We find that export support raises firm-level exports within markets. However, e...

摘要：This study investigates the mechanisms affecting sleep choice and explores whether commitment devices and monetary incentives can be used to promote healthier sleep habits. To this end, we conducted a field experiment with college students, providing them incentives to sleep and collecting data from wearable activity trackers, surveys, and time-use diaries. Monetary incentives were effective in increasing sleep duration with some evidence of persistence after the incentive was removed. We unco...
