摘要：We develop a framework to evaluate the impact of market integra-tion, accounting for spillovers between multiple distribution chan-nels. We adapt the standard random coefficients logit demand model to allow for substitution between channels and consumer arbitrage across countries. We apply our framework to the European por-table PC market, where geoblocking practices that restrict online cross-border trade have recently been banned. Consumers in high income countries gain most from price conve...

摘要：We present a learning-based selection argument for Linear Bayesian Nash equilibrium in a Walrasian auction. Endowments vary stochastically; traders model residual supply as linear, estimate its slope from past trade data, and periodically update these estimates. In the standard setting with quadratic preferences, we show that this learning process converges to the unique LBN. Anonymity and statistical learning therefore support this commonly used equilibrium selection rule. (JEL D43, D44, D83)

摘要：Over the past decades the number of news outlets has increased dramatically, but the quality of news products has declined. We propose a model to reconcile these facts where consumers' attention allocation decisions not only depend on but also affect news outlets' quality choices. When competition is intensified by new entries, the informativeness of the news industry rises. Thus, attention is diverted from existing outlets, reducing their incentives to improve news quality, which begets a dow...

摘要：Spending time with a spouse is a major gain from marriage. We extend the classical collective model of the household to allow for togetherness between spouses. Togetherness takes the form of joint leisure and joint care for children. Using revealed preference conditions and Dutch data over the years 2009-2012, we find that households are willing to pay euro 1.20 per hour-10 percent of the average wage-to convert private leisure to joint leisure and euro 2.10 per hour to convert private childca...

摘要：We consider the single-sector version of the Melitz-Ottaviano model of monopolistic competition with heterogeneous firms. We characterize the first-best and market allocations. We find that the market provides the first-best level of entry but too little selection; hence, the market provides too many varieties and too little aggregate quantity, and allocates too little (much) production to low (high) cost realizations. Allowing for a broad family of quantity allocation functions, we establish ...

摘要：This paper studies the effects of time preferences on cooperation in an infinitely repeated prisoner's dilemma game experiment. Subjects play repeated games in the lab, all decisions at once, but stage game payoffs are paid over an extended period of time. Changing the time window of stage game payoffs (weekly or monthly) varies discount factors, and a delay for the first-stage game payoffs eliminates/weakens present bias. First, subjects with weekly payments cooperate more than subjects with ...

摘要：We provide a general framework to analyze competition between any number of symmetric two-sided transaction platforms, in which buyers and sellers can multihome. We show how key primitives such as the number of platforms, the fraction of buyers that find multihoming costly, the value of transactions, and the degree of user heterogeneity jointly determine the level and structure of platform fees. Even though platform entry always reduces the total fee level, whether it shifts the fee structure ...

摘要：In many real-world settings, an action that affects the value of a product or service is self-reported rather than publicly observable. We investigate self-reporting when self-reports serve as a signal of sender productivity. In our model, a sender chooses an action and then sends a message concerning the action to multiple receivers. Receivers then bid for the sender's service after deciding whether to audit the sender. We find that self-reporting can reverse the standard result in signaling ...

摘要：We study the implications of biased consumer beliefs for search market outcomes in the seminal framework due to Diamond (1971). Biased consumers base their search strategy on a belief function that specifies for any (true) distribution of utility offers in the market a possibly incorrect distribution of utility offers. If biased consumers overestimate the best offer in the market, a novel type of equilibrium may emerge in which firms make exceptionally favorable offers in order to meet biased ...

摘要：We study mix-and-match compatibility choices of firms selling com-plementary products in a dynamic setting. Contrary to what hap-pens in a static setting where symmetric firms choose compatibility (Matutes and Regibeau 1988 ), when switching costs are high and firms make price discrimination based on past purchases, symmet-ric firms choose incompatibility to soften future competition if the discount factor is large, which harms consumers. Interoperability increases consumer surplus at least fo...
