摘要：We use a population resettlement program in Indonesia to identify long-run effects of intergroup contact on national integration. In the 1980s, the government relocated two million ethnically diverse migrants into hundreds of new communities. We find greater integration in fractionalized communities with many small groups, as measured by national language use at home, intermarriage, and children's name choices. However, in polarized communities with a few large groups, ethnic attachment increa...

摘要：To investigate the enforcement value of third-party information on potentially collusive taxpayers, I study an anti-tax evasion program that rewards consumers for ensuring that firms report sales and establishes a verification system to aid whistle-blowing consumers in Sao Paulo, Brazil (Nota Fiscal Paulista). Firms reported sales increased by at least 21 percent over 4 years. The results are consistent with fixed costs of concealing collusion, increased detection probability from whistle-blow...

摘要：We study the informational events that trigger equilibrium shifts in coordination games with incomplete information. Assuming that the distribution of the changes in fundamentals has fat tails, we show that majority play shifts either if fundamentals reach a critical threshold or if there are large common shocks, even before the threshold is reached. The fat-tail assumption matters because it implies that large shocks make players more unsure about whether their payoffs are higher than others....

摘要：We revisit the revenue comparison of standard auction formats, including first-price, second-price, and English auctions. We rank auctions according to their revenue guarantees, i.e., the greatest lower bound of revenue across all informational environments, where we hold fixed the distribution of bidders' values. We conclude that if we restrict attention to the symmetric affiliated models of Milgrom and Weber (1982) and monotonic pure-strategy equilibria, first-price, second-price, and Englis...

摘要：What makes an asset a safe asset? We study a model where two countries each issue sovereign bonds to satisfy investors' safe asset demands. The countries differ in the float of their bonds and the fundamental resources available to rollover debts. A sovereign's debt is safer if its fundamentals are strong relative to other possible safe assets, not merely strong on an absolute basis. If demand for safe assets is high, a large float enhances safety through. a market depth benefit. If demand for...

摘要：International trade collapsed, and also became much less multi-lateral, during the 1930s. Previous studies, looking at aggregate trade flows, have argued that trade policies had relatively little to do with either phenomenon. Using a new dataset incorporating highly disaggregated information on the United Kingdom's imports and trade policies, we find that while conventional wisdom is correct regarding the impact of trade policy on the total value of British imports, discriminatory trade polici...

摘要：We study empirically how past exposure to conflict in origin countries makes migrants more violence-prone in their host country, focusing on asylum seekers in Switzerland. We exploit a novel and unique dataset on all crimes reported in Switzerland by the nationalities of perpetrators and of victims over 2009-2016. Our baseline result is that cohorts exposed to civil conflict/mass killing during childhood are 35 percent more prone to violent crime than the average cohort. This effect is particu...

摘要：We model the dynamics of discrimination and show how its evolution can identify the underlying source. We test these theoretical predictions in a field experiment on a large online platform where users post content that is evaluated by other users on the platform. We assign posts to accounts that exogenously vary by gender and evaluation histories. With no prior evaluations, women face significant discrimination. However, following a sequence of positive evaluations, the direction of discrimin...

摘要：This paper develops a new approach to test for downward wage rigidity by examining transitory shocks to labor demand (i.e., rainfall) across 600 Indian districts. Nominal wages rise during positive shocks but do not fall during droughts. In addition, transitory positive shocks generate ratcheting: after they have dissipated, wages do not adjust back down. Ratcheting reduces employment by 9 percent, indicating that rigidities distort employment levels. Inflation, which is unaffected by local ra...

摘要：This paper shows that a macro model with segmented financial markets can generate sizable movements in housing prices in response to changes in credit conditions. We establish - theoretically that reductions in mortgage rates always have a positive effect on prices, whereas the relaxation of loan-to-value constraints has ambiguous effects. A quantitative version of the model under perfect foresight accounts for about one-half of the observed price increase in the United States in the 2000s. Wh...
