Dominant digital platforms such as Google and Facebook collect personal information of users by default precipitating a market failure in the market for personal information. We establish the economic harms from the market failure. We discuss conditions for eliminating the market failure and...

We study an e-commerce platform’s incentives to delist IP-infringing products and the effects of introducing a liability regime that induces the platform to increase its screening intensity. We identify conditions under which platform liability is socially desirable (respectively, undesirable)...

How do firms respond to entry in multi-sided markets? We address this question by studying the impact of Craigslist, a website providing classified-advertising services, on local US newspapers. We exploit temporal and geographical variation in Craigslist’s entry to show that newspapers with...

We study competition among upstream firms when each of them sells a portfolio of distinct products and the downstream has a limited number of slots (or shelf space). In this situation, we study how bundling affects competition for slots. When the downstream has k number of slots, social...

We examine the intersection of patents and antitrust where a patent holder uses the monopoly power it possesses in the market for a patented product to exclude competitors in an adjacent market and attempt to monopolize or monopolize the adjacent market. The present scheme for awarding patents...
