I build a simple dynamic model of the formation of an international social network of importers and exporters. Firms can only export into markets in which they have a contact. They acquire new contacts both at random, and via their network of existing contacts. This model explains (i) the...

I propose a network/search view of international trade in differentiated products. I present evidence that supports the view that proximity and common language/colonial ties are more important for differentiated products than for products traded on organized exchanges in matching international...

Parochial politics is typically associated with poor leadership and low levels of public good provision. This paper explores the possibility that community involvement in politics need not necessarily worsen governance and, indeed, can be efficiency-enhancing when the context is appropriate....

We define a general class of network formation models, Statistical Exponential Random Graph Models (SERGMs), that nest standard exponential random graph models (ERGMs) as a special case. We provide the first general results on when these models' (including ERGMs) parameters estimated from the...

This paper studies costly network formation in the context of risk sharing. Neighboring agents negotiate agreements as in Stole and Zwiebel (1996), which results in the social surplus being allocated according to the Myerson value. We uncover two types of inefficiency: overinvestment in social...

A network/search view of international trade in differentiated products is proposed. It is shown that this view can explain the importance of ethnic and extended family ties in trade, the success of diversified trading intermediaries such as Japan's sogo shosha, and the ubiquity of government...

We explore the role of government in the nexus of finance and trade starting from the earliest days of organised finance in England and then broadening the analysis to 84 countries from 1960 to 2004. For 18th century England, we find that the government expenditures and international trade did...

The paper studies the solvency of the Indian public sector and the eventual monetization and inflation implied by stabilization of the debt-GNP ratio without any changes in the primary deficit. The nonstationarity of the discounted public debt suggests that indefinite continuation of the pattern...

This paper, a chapter in the forthcoming Oxford University Press Handbook of the Indian Economy, edited by Chetan Ghate, considers India's experience with fiscal (responsibility) rules during the past decade. After reviewing the basic facts concerning public debt and deficits in India, the...

We examine the differential impact of portfolio debt, portfolio equity, and FDI inflows on 37 manufacturing industries, 99 countries, 1991-2007, extending Rajan-Zingales (1998). We utilize external finance dependence measures in a series of cross-sectional regressions of manufacturing...
