I study optimal information provision by a search goods seller. While the seller controls a consumer's pre-search information, which decides whether she will engage in costly search for the product, he cannot control her post-search information because the consumer would inevitably learn the...

An organization must decide which proposals to fund. In evaluating the proposals, the organization may rely on those applying for funding to produce evidence about the merits of their own proposals. We consider the role of a capacity constraint preventing the organization from funding all...

The psychology literature provides ample evidence that people have difficulties taking the perspective of less-informed others. This paper presents a controlled experiment showing that this "curse of knowledge" can cause comparative overconfidence and overentry into competition. In a broader...

We propose an analysis of platform competition based on the academic literature with a view towards competition policy. First, we discuss to which extent competition can emerge in digital markets and show which forms it can take. In particular, we underline the role of dynamics, but also of...

This paper studies how restricting data exchange between firms affects market competition in the app economy. The identification exploits iOS's privacy policy update, which limits apps from tracking users across other apps using identifiers. We find that the iOS update reduces startup app...

This paper discusses how ICT and emerging electronic commerce in consumer products influence the relative efficiency in production of households and firms, resulting in changes in the division of tasks between these two types of agents. Increased information and competence of households, in...

This paper studies unshrouding decisions in a framework similar to Gabaix and Laibson (2006), but considers an alternative unshrouding mechanism where the impact of advertising add-on information depends on the number of unshrouding firms. We show that shrouding becomes less prevalent as the...

Attracting attention is a basic feature of economic life but no standard economic problem. A new theoretical model is developed which describes the general structure of competition for attention and characterizes equilibria. The exogenous fundamentals of an attention economy are the space of...
