摘要：Export price levels exhibit tremendous cross-national and spatial variation, even within narrowly defined industries. Standard theories attribute this variation to within-industry quality specialization. This paper argues that a significant portion of the export price variation is driven by rich and remote economies specializing in high-market power segments of industries. I also argue that this particular pattern of specialization (i) accounts for 30 percent of the overall gains from trade, a...

摘要：In a world characterized by asymmetric learning, promotions can serve as signals of worker ability, and this, in turn, can result in inefficient promotion decisions. If the labor market is competitive, the result will be practices that reduce this distortion. We explore how this logic affects human capital investment decisions. We show that, if commitment is possible, investments will be biased toward the accumulation of firm-specific human capital. We also consider what happens when commitmen...

摘要：Commodity taxation often involves uniform tax rates. We use alcohol laws that tax differentiated spirits with a comprehensive uniform markup to evaluate redistribution generated by such simple tax policy. We document preference heterogeneity among consumers, variation in product demand elasticities, and market power among producers with heterogeneous product portfolios. Relative to more flexible product-level markups recognizing demand heterogeneity and strategic price responses of firms, we f...

摘要：Revealed preference restrictions are increasingly used to predict demand behavior at new budgets of interest and as shape restrictions in nonparametric estimation exercises. However, the restrictions imposed are not sufficient for rationality when predictions are made at multiple budgets. 1 highlight the non-convexities in the set of predictions that arise when making multiple predictions. 1 develop a mixed integer programming characterization of the problem that can be used to impose rational...

摘要：Since Telser (1960), there is a well-established argument that a competitive market will not provide service due to freeriding. We show that with search frictions, the market may well provide service if the cost of doing so is not too large. Any market equilibrium with service provision has two or more firms providing service, implying overprovision of service as the social optimum mandates at most one service provider Firms that provide service and those that do not can coexist, where consume...

摘要：The lack of hard evidence in allegations about sexual misconduct makes it difficult to separate true allegations from false ones. We provide a model in which victims and potential libelers face the same costs and benefits from making an allegation, but the tendency for perpetrators of sexual misconduct to engage in repeat offenses allows semiseparation to occur, which lends credibility to such allegations. Our model also explains why reports about sexual misconduct are often delayed, and why t...

摘要：A manager who learns privately about a project over time may want to delay quitting it if recognizing failure/lack of success hurts his reputation. In the banking industry, managers may want to roll over bad loans. How do distortions depend on expected project quality? What are the effects of releasing public information about quality? A key feature of banks is that managers learn about project quality from bad news, i.e., a default. We show that in such an environment, distortions tend to inc...

摘要：We study how changes in market structure affect how firms engage in second-degree price discrimination. Specifically, we study how a large incumbent cable firm changes its menu of price-quality offerings and mixed bundles in response to entry Competition strongly decreases the rate at which prices increase in quality and induces the incumbent to introduce additional medium- to high-quality offerings that the incumbent could have introduced absent competition but chose not to. Our findings are ...
