This paper considers a dynamic duopoly market with strategic, price setting firms and an infinite set of fully rational, privately informed consumers who enter the market sequentially. I show that there exists a sequential equilibrium in which prices converge to their realized product qualities...

We examine the issue of whether two monopolists which produce substitutable goods should be regulated by one (centralization) or two (decentralization) regulatory authorities, when the regulator(s) can be partially captured by industry. Under full information, two decentralized agencies - each...

This paper addresses the pricing problem of an online service marketplace under asymmetric information. An example is an online learning platform such as Coursera that provides courses from suppliers (in this case, universities) to learners. We focus on the matching function of the marketplace...

I study the question of how much product information should be available to consumers. A monopolist sells one unit of product. The consumer is initially uninformed of the product value but can incur costs to observe a noisy signal of his valuation. I show that consumer surplus can be increasing...

We study the regulation of a monopolistic firm that provides a non-marketed output based on multiple substitutable inputs. The regulator is able to observe the effectiveness of the provision, but faces information asymmetries with respect to the efficiency of the firm’s activities. Motivated...

We study buyer-optimal information structures under monopoly pricing. The information structure determines how well the buyer learns his valuation and affects, via the induced distribution of posterior valuations, the price charged by the seller. Motivated by the regulation of product...

This chapter reviews recent theoretical work on the design of regulatory policy, focusing on the complications that arise when regulated suppliers have better information about the regulated industry than do regulators. The discussion begins by characterizing the optimal regulation of a monopoly...

Digital platforms facilitate interactions between consumers and merchants that allow collection of profiling information which drives innovation and welfare. Private incentives, however, lead to information asymmetries resulting in market failures both on-platform, among merchants, and...
