We examine the relationship between large firms and the rising profit share in a model that features oligopolistic competition and consumer heterogeneity. Conditional on the sales distribution, the presence of consumer heterogeneity increases the profit share because it increases firm-level...

This paper explores the application of oblivious equilibrium to concentrated industries. We define an extended notion of oblivious equilibrium that we call partially oblivious equilibrium (POE) that allows for there to be a set of "dominant firms'', whose firm states are always monitored by...

This paper provides a positive political economy analysis of the most important revision of the U.S. supervision and regulation system during the last two decades, the 1991 Federal Deposit Insurance Corporation Improvement Act (FDICIA). We analyze the impact of private interest groups as well as...

This paper contrasts direct election with political appointment of regulators. When regulators are appointed, regulatory policy becomes bundled with other policy issues the appointing politicians are responsible for. Since regulatory issues are not salient for most voters, regulatory policy...

The increased burden of disclosure and governance regulations is often cited as a key reason for the significant decline in the number of publicly-listed companies in the U.S. We explore the connection between regulatory costs and the number of listed firms by exploiting a regulatory quirk: many...

We document a novel bidding pattern observed in procurement auctions from Japan: winning bids tend to be isolated. There is a missing mass of close losing bids. This pattern is suspicious in the following sense: it is inconsistent with competitive behavior under arbitrary information structures....

This paper discusses two pertinent issues dealing with the global liquidity crisis -- global prudential regulation reform, and reassessment of using international reserves in the crisis. We point out the paradox of prudential regulations -- while the identity of economic actors that benefited...

We propose an activity-generating theory of regulation. When courts make errors, tort litigation becomes unpredictable and as such imposes risk on firms, thereby discouraging entry, innovation, and other socially desirable activity. When social returns to innovation are higher than private...

The government has responded to misleading advertising by banning it, engaging in counter-advertising and taxing the product. In this paper, we consider the social welfare effects of those different responses to misinformation. While misinformation lowers consumer surplus, its effect on social...
