摘要：We measure the effects of debt dilution on sovereign default risk and study debt covenants that could mitigate these effects. We calibrate a baseline model with endogenous debt duration and default risk (in which debt can be diluted) using data from Spain. We find that debt dilution accounts for 78 percent of the default risk in the baseline economy and that eliminating dilution increases the optimal duration of sovereign debt by almost 2 years. Eliminating dilution also increases consumption ...

摘要：This paper analyzes the inefficiencies arising from the combination of fixed exchange rates, nominal rigidity, and free capital mobility. We document that nominal wages are downwardly rigid in emerging countries. We develop an open-economy model that incorporates this friction. The model predicts that the combination of a currency peg and free capital mobility creates a negative externality that causes over-borrowing during booms and high unemployment during contractions. Optimal capital contr...

摘要：This paper develops a price-theoretic framework for matching markets with heterogeneous preferences. The model departs from the Gale and Shapley model by assuming that a finite number of agents on one side (colleges) are matched to a continuum of agents on the other side (students). We show that stable matchings correspond to solutions of supply and demand equations, with the selectivity of each college playing a role similar to that of prices. We apply the model to an analysis of how competit...

摘要：We study decentralized college admissions with uncertain student preferences. Colleges strategically admit students likely to be overlooked by competitors. Highly ranked students may receive fewer admissions or have a higher chance of receiving no admissions than those ranked below. When students' attributes are multidimensional, colleges avoid head-on competition by placing excessive weight on school-specific attributes such as essays. Restricting the number of applications or wait-listing al...

摘要：We exploit the randomness of weather and the relationship between weather and moviegoing to quantify social spillovers in movie consumption. Instrumenting for early viewership with plausibly exogenous weather shocks captured in LASSO-chosen instruments, we find that shocks to opening weekend viewership are doubled over the following five weekends. Our estimated momentum arises almost exclusively at the local level, and we find no evidence that it varies with either ex post movie quality or the...

摘要：We study how firms differ from their competitors using new time-varying measures of product similarity based on text-based analysis of firm 10-K product descriptions. This year-by-year set of product similarity measures allows us to generate a new set of industries in which firms can have their own distinct set of competitors. Our new sets of competitors explain specific discussion of high competition, rivals identified by managers as peer firms, and changes to industry competitors following e...

摘要：Incumbent politicians tend to receive more votes when economic conditions are good. In this paper we explore the source of this correlation, exploiting the exceptional evidence provided by the Spanish Christmas Lottery. Because winning tickets are typically sold by one lottery outlet, winners tend to be geographically clustered. This allows us to study the impact of exogenous good economic conditions on voting behavior. We find that incumbents receive significantly more votes in winning provin...
