We study the interplay between a "one person-one vote" political system and a "one share-one vote" corporate governance regime. The political system sets Pigouvian subsidies, while corporate governance determines firm-specific public good investments. Our analysis highlights a two-way feedback...

The economic effects of climate change vary across both time and space. To study these effects, this paper builds a global economy-climate model featuring a high degree of geographic resolution. Carbon emissions from the use of energy in production increase the Earth's (average) temperature and...

The extent of voluntary cooperation in the presence of externalities is shown as an equilibrium outcome in the supply and demand framework. The analysis uses familiar ingredients to provide a new way of understanding the results of the extensive literature beginning with Buchanan, Coase, Ostrom,...

The epidemiological literature suggests that virus transmission occurs only when individuals are in relatively close contact. We show that if society can control the extent to which economic agents are exposed to the virus and agents can commit to contracts, virus externalities are local, and...

Developing country megacities suffer from severe road traffic congestion, yet the level of congestion is not a direct measure of equilibrium inefficiency. I study the peak-hour traffic congestion equilibrium in Bangalore. To measure travel preferences, I use a model of departure time choice to...

We examine the desirability of granting "safe harbor" provisions to creditors of financial intermediaries in sale-and-repurchase (repo) contracts. Exemption from an automatic stay in bankruptcy enables financial intermediaries to raise greater liquidity and induces entry of intermediaries with...

Individuals might experience negative utility from not consuming a popular product. For example, being inactive on social media can lead to social exclusion or not owning luxury brands can be associated with having a low social status. We show that, in the presence of such spillovers to...

A growing fraction of companies globally have made commitments to reduce their carbon emissions by a certain date. While the companies that make commitments subsequently reduce their emissions, the effect on overall emissions of companies (including those that do not commit) has been small; the...

This article explores subjects in optimal income taxation characterized by recent research interest, practical importance in light of concerns about inequality, potential for misunderstanding, and prospects for advancement. Throughout, the analysis highlights paths for further investigation....

Forward-looking investments determine the resilience of firms' supply chains. Such investments confer externalities on other firms in the production network. We compare the equilibrium and optimal allocations in a general equilibrium model with an arbitrary number of vertical production tiers....
