摘要：This article examines the welfare consequences of a trade association in an exporting country on consumers in destination countries. We estimate a structural model of the Chilean Salmon exporting industry that endogenizes firms' pricing and export decisions. Our results show that the trade association has a positive effect on consumer utility and involves higher marginal costs of production, consistent with higher quality products. Reduced form analysis estimates price effects associated with ...

摘要：We study oligopolistic competition by firms practicing second-degree price discrimination. In line with the literature on demand estimation, our theory allows consumers' propensity to switch brands to vary with tastes for product quality. If low-type consumers are sufficiently more (respectively, less) prone to switch brands than are high types, (i) quality provision is inefficiently low at the bottom (respectively, high at the top) of the product line, and (ii) informational rents are positiv...

摘要：This article provides a full characterization of the competitive effects of horizontal mergers in the Cournot model with heterogeneous firms and constant marginal costs. We show that price effects depend only on the smaller merging firm's market share and the number of firms but are independent of the distribution of market shares among other firms. Standard concentration measures, instead, are often misleading. We also provide simple-yet general-closed-form solutions for merger effects based ...

摘要：We study the optimal design of a monopoly platform that interacts with heterogeneous firms and consumers who face uncertainty about product values and prices. Consumers search randomly among firms recommended by the platform. The platform designs a menu of contracts tailored to different firm types and allocates consumer visits across these firms. We show that the optimal platform design creates a superstar effect, whereby high-type firms capture a disproportionately large market share, and im...

摘要：We study a two-period learning model where a sequentially rational regulator builds a reputation for strict enforcement and self-interested firms test the regulator's enforcement propensity through their misconduct. In the transparent setting, where misconduct and enforcement are observable between the firms, the regulator's reputation concern endogenously creates positive or negative enforcement externalities between the firms. When the reputation concern is strong, the enforcement externalit...
