We conduct a survey of economists and a representative sample of Americans to infer the reduction in the perceived value of a paper when its authors have conflicts of interest (CoI), i.e., they have financial, professional, or ideological stakes in the outcome of the results. On average, a CoI...

We discuss the design of an effective merger review policy for the 21st century. We argue that the practice of the past decades is inadequate and propose a move towards much stronger rebuttable structural presumptions. These presumptions establish that all mergers above certain thresholds are...

We study England between 2000 and 2011 when internet diffusion spread rapidly and there was a high profile medical article (falsely) linking the MMR...

Central features of today's electronic communications markets are complementarities between the different layers of the value chain, substitutability between some applications, network effects in the provision of content and services, two-sided business models that partly involve indirect...

Regulators have long been aware of the social aspects of communication. In the past, regulated monopolists have provided Universal Service Obligations, typically funded via a system of cross-subsidies. In this paper, we first review the rationale for imposing Universal Service Obligations, based...
