Just and efficient allocations of charity have attracted much academic and media attention. The sources of inefficiency and unjust are important to understand yet understudied. Our study aims to fill this void by directly modelling the victims' market in a collective reputation framework. By...

This paper introduces a simulation algorithm for evaluating the log-likelihood function of a large supermodular binary-action game. Covered examples include (certain types of) peer effect, technology adoption, strategic network formation, and multi-market entry games. More generally, the...

An extensive experimental literature has documented miscoordination in establishing cooperative relationships when they can be supported in indefinitely repeated games: some people systematically try to cooperate, while others do not. The literature has had little success in finding personal...

The experimental literature on repeated games has largely focused on settings where players discount the future identically. In applications, however, interactions often occur between players whose time preferences differ. We study experimentally the effects of discounting differentials in...

We compare how well agents aggregate information in two repeated social learning environments. In the first setting agents have access to a public data set. In the second they have access to the same data, and also to the past actions of others. Despite the fact that actions contain no...

This chapter examines the multifaceted interactions between top digital platforms and technology ventures across capital, labor, innovation, and product markets. Exploring how venture investments, talent flows, strategic alliances, and competitive behaviors can shape the innovation ecosystem,...

We leverage a comprehensive dataset of electronic invoices from Chilean firms to document new facts on price dispersion across buyers of manufactured intermediate goods. Over half of firm-to-firm manufacturing sales are accounted for by products that are purchased by more than one buyer in the...

This paper studies the effect of nonlinear pricing on markups and misallocation. We develop a general equilibrium model of firms that are allowed to set a quantity-dependent pricing schedule--contrary to the typical assumption in macroeconomic models. Without the restriction to linear pricing,...

Adverse selection is a classic market failure known to limit or "unravel"' trade in high-quality insurance and many other economic settings. While the standard theory emphasizes quality distortions, we argue that selection has another big-picture implication: it unravels competition among...
