In e-commerce, where information collection is essentially costless and geographic location of traders matters very little, fierce competition between providers of similar services is expected. We consider a model where two e-commerce intermediaries (internet shops) compete for sellers. We show...

We study the design of information disclosure in a dynamic multi-agent research contest, where each agent privately searches for innovations and submits his best to compete for a winner-takes-all prize. We find that although submission is a onetime event for each agent, different disclosure...

Besides their role in reducing frictions and facilitating trade, two-sided platforms increasingly collect and process data, e.g., supply and demand forecasts, that can further affect market outcomes. This paper studies how a platform may choose to disclose its information about future demand to...

We develop a theoretical model to analyse the e ect of competition on the conflict of interest arising from the issuer pay compensation model of the credit rating industry. We nd that relative to monopoly, rating agencies are more likely to inflate ratings under competition, resulting in lower...

As is well-known from the literature on oligopolistic competition with incomplete information, firms have an incentive to share private demand information. However, by assuming verifiability of demand data, these models ignore the possibility of strategic misinformation. We show that if firms...

I model access to influence as a two-sided matching market between a continuum of experts and two vertically differentiated gatekeepers under sequential directed search. Real-world examples include academic publishing, venture capital, job search or political agenda setting. The equilibrium is...

I study optimal disclosure policies in sequential contests. A contest designer chooses at which periods to publicly disclose the efforts of previous contestants. I provide results for a wide range of possible objectives for the contest designer. While different objectives involve different...
