This paper shows that the result of Ju and Krishna (2002, 2005), i.e., the non-monotonicity in the comparative statics across regimes, disappears, if exporters differ in their productivities, which provides very different predictions about the results of policy changes

This paper reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional...

In this paper we study the determinants of business groups' ownership structure using unique panel data on Korean chaebols. In particular, we attempt to understand how pyramids form over time. We find that chaebols grow vertically (that is, pyramidally) as the family uses well-established group...

We study the impact of information and communication technology on growth through its impact on organization and innovation. Agents accumulate knowledge through two activities: innovation (discovering new technologies) and exploitation (learning how to use the current technology). Exploitation...

This paper examines the relationship between membership in social fraternities and sororities and binge drinking among 18-24 year old full-time four-year college students who participated in the 1995 National College Health Risk Behavior Survey. To deal with unobserved heterogeneity in binge...

This paper proposes a new equilibrium concept – organizational equilibrium – for models with state variables that have a time-inconsistency problem. The key elements of this equilibrium concept are: (1) agents are allowed to ignore the history and restart the equilibrium; (2) agents can wait...

This paper analyzes how different organizational structures between funding and implementing agencies affect the quality of aid delivered and social agendas pursued across neighboring villages in a set disaster context. We model the implied objective functions and trade-offs concerning aid...

The provision of public goods often relies on voluntary contributions and cooperation. While most of the experimental literature focuses on individual contributions, many real-world problems involve the formation of institutions among subgroups (coalitions) of players. International agreements...

We report a puzzling pair of facts concerning the organization of science. The concentration of research output is declining at the department level but increasing at the individual level. For example, in evolutionary biology, over the period 1980 to 2000, the fraction of citation-weighted...

This paper considers the role of the allocation of scientific credit in determining the organization of science. We examine changes in that organization and the nature of credit allocation in the past half century. Our contribution is a formal model of that organizational choice that considers...
