摘要：Distributional decisions regularly involve multiple payoff components. In a series of experiments , we show that individuals sometimes exhibit narrow equity concerns: applying fairness preferences narrowly on a specific component of payoffs rather than on broader payoff consequences. This behavior results in different distributional decisions depending on which payoff component we frame individuals to consider. We document narrow equity concerns in an exceedingly simple setting -in which payof...

摘要：In many online markets , consumers have to spend time and effort browsing through products. The addition of new products could make other products less visible , creating congestion externalities. Using Android app store data , I take advantage of a natural experiment-a redesign of part of the store-to show evidence of congestion externalities online: more apps in the market directly reduce per app usage / downloads. The natural experiment also increases long -run entry , but a structural dema...

摘要：This paper investigates the welfare effects of vertical integration in China's movie industry. We leverage data covering all theaters and 423 popular movies in China during 2014-2018. We find no evidence of integrated movies being foreclosed to rival theaters. Integrated theaters show movies for longer , allocate more screenings , and charge lower prices. We estimate a model of consumers' demand and theaters' screening decisions. Integrated theaters internalize a substantial fraction of their ...

摘要：A monopolist data seller offers information to privately informed data buyers. I characterize the seller's optimal menu, which screens between two types of buyers. Buyers' preferences for information allow the seller to extract all surplus, and the opti-mal menu's features are determined by the interaction between buyers' strategic incentives and the correlation of their pri-vate information. The seller offers perfect information to the buyer with the highest willingness to pay and partial inf...

摘要：Contributions toward public goods often reveal information that is useful to others considering their own contributions. This experiment compares static and dynamic contribution decisions to determine how contingent reasoning differs in dynamic decisions where equilibrium requires understanding how future information can inform about prior events. This identifies partially cursed individuals who can only extract partial information from contingent events , others who are better at extracting i...

摘要：Global value chains create opportunities for North -South technology diffusion. This paper studies technology transfer in value chains when contracts are incomplete and input production technologies are imperfectly excludable. It introduces a new taxonomy of value chains based on whether the headquarters firm benefits from imitation of its supplier's technology. In inclusive value chains , where imitation is beneficial , the headquarters firm promotes technology diffusion. But in exclusive val...

摘要：Our novel approach to modeling monopolistic competition with heterogeneous firms and consumers involves spatial product differentiation, in either a geographical space or a space of characteristics. In addition to price, each firm chooses location in space. We formulate conditions for positive sorting-more-productive firms serve larger market segments and face tougher competition-and for existence and uniqueness of equilibrium. To quantify the role of sorting, we calibrate the model using hair...

摘要：E -commerce has led to a surge in products being returned after purchase. We analyze product returns as resulting from a trade-off between the social waste of returns and the search efficiency gains of being able to inspect a product's value after purchase. We find whenever returns are efficient , the market generates too few returns, as the parties involved in the transaction do not internalize the welfare benefit of consumers continuing their search , generating profits for other firms. We a...

摘要：A seller markets a good to a customer whose willingness to pay depends on his private type and the good's quality. The seller designs a screening mechanism that specifies both transfers and information revealed about quality. We show that the optimal mechanism can be implemented by a menu of price -experiment pairs, featuring both price discrimination and information discrimination: buyers with higher private types face lower prices and receive less discerning positive signals. Moreover, we de...

摘要：Technological innovations like broadcast television and the internet challenge local newspapers' business model of bundling their local content with third-party content, such as wire national news. We examine how the entry of television affected newspapers and news diets in the United States. We construct a dataset of newspapers' economic performance and content choices from 1944 to 1964 and exploit quasi-random variation in the rollout of television to show its negative impact in the readersh...
