摘要：This article studies discrimination in a model in which promotions are used as signals of worker ability. The model can account for statistical and taste-based discrimination. In the short run, a positive discrimination policy is beneficial for workers in the middle of the ability distribution, because these workers are promoted if and only if the policy is in place. Instead, workers of either high or low ability suffer from the policy. In the long run, the policy benefits all targeted workers...

摘要：In a dynamic storable good market where demand changes over time, we investigate the producer's strategic incentives to hold inventories in response to the possibility of buyer stockpiling. The literature on storable goods has demonstrated that buyer stockpiling in anticipation of higher future prices harms the producer's profitability, particularly when the producer cannot commit to future prices. We show that the producer's inventories act as a strategic device to mitigate the loss from the ...

摘要：Learning from friends is a key process by which consumers acquire information about available products. This article embeds social learning in a model of firms producing differentiated products. I consider how the structure of social relationships between consumers influences pricing and welfare. In particular, how a variety of characteristics of social networks - distribution of friendships, homophily, clustering, and correlations between an individual's preferences and number of friends - in...

摘要：How can a marketplace introduce mechanisms to overcome inefficiencies caused by adverse selection? In this article, I use a unique data set that follows eBay sellers to show that reputation is a major determinant of price variations. I develop a model of sellers' dynamic behavior where sellers have heterogeneous qualities unobservable by buyers. Using reputation as a signal of quality, I structurally estimate the model to uncover buyers' utility and sellers' costs and underlying qualities. I s...

摘要：We introduce a new, simple-to-compute test of independence of valuations and the number of bidders for ascending button auctions with symmetric, conditionally independent private values. The test involves estimating the expected revenue drop from excluding a bidder at random, which can be computed as a scaled sample average of a difference of order statistics. This object also provides a bound on counterfactual revenue changes from optimal reserve pricing or bidder mergers. We illustrate the a...

摘要：I analyze a model of production in a competitive environment with heterogeneous firms. Efficient production requires individuals within the organization to take noncontractible actions for which rewards must be informally promised rather than contractually assured. The credibility of such promises originates from a firm's future competitive rents. In equilibrium, heterogeneous firms are heterogeneously constrained, and competitive rents are inefficiently concentrated at the top. I explore seve...

摘要：We construct a comprehensive sample of takeovers in Belgium that shows they are remarkably common. Takeovers involve both small and large firms and, over a five-year period, 17% of private sector employment. We estimate their impact on employment growth using a framework that explicitly takes into account that takeovers involve pairs of firms and that post-merger outcomes are heterogeneous. The average merger temporarily reduces employment of the combined entity by -1.4%. Mergers likely to be ...

摘要：We evaluate the welfare effects of the 1997 Boeing-McDonnell Douglas merger in the medium-sized, wide-body aircraft industry. We find that the merger led to lower prices. To explain the price drop, we develop a dynamic oligopoly game with learning-by-doing. We quantify the welfare effects of the merger by incorporating both increased market power and merger efficiencies from accelerated learning-by-doing. Our dynamic analysis indicates that net consumer surplus increased by as much as $5.14 bi...

摘要：We examine trends in the productivity of the pharmaceutical sector over the past three decades. Motivated by Ricardo's insight that productivity and rents are endogenous to demand when inputs are scarce, we examine the industry's aggregate Research and Development (R&D) production function. Using exogenous demand shocks to instrument investments, we find that demand growth can explain a large portion of R&D growth. Returns to scale have been stable, whereas total factor productivity has declin...

摘要：This article revisits the opportunism problem faced by an upstream monopolist contracting with several retailers over secret agreements, when contracts are linear. We characterize the equilibrium under secret contracts and compare it to that under public contracts in a setting allowing for general forms of demand and retail competition. Market distortions are more severe under secret contracts if and only if retailers' instruments are strategic complements. We also investigate the effect of op...
