International Fragmentation and Agglomeration: From Theory to Empirics

Theory and Methods Research Paper 2006 / 40 International Trade , Security and Transnational Terrorism : Theory and Empirics

In this paper, we offer a general analytical framework illustrating the complex two-way interactions between trade and transnational terrorism. We then survey the recent economic literature in light of this framework by pointing to the importance in empirical studies a) to control appropriately for theses interactions, b) to distinguish between "source" countries and "target" countries of terro...

Sample to Sample Uctuations in Fragmentation and Agglomeration Processes

The uctuation dynamics in steady state fragmentation and aggregation processes is analyzed from a kinetic point of view. The uctuations n(x; t) in the number of particles of size between x and x + x, in a sample with average occupation number N(x), appear to behave like sums of uncorrelated events: < n(x; t) 2 >/ N(x). The implications of this fact for the applicability of a mean eld descriptio...

Market Microstructure: Theory and Empirics

This paper reviews the literature on market microstructure. Particular emphasis is given to the research dealing with the impact that a speci c trading mechanism might have on price behaviour and with the comparison of the performance of alternative market structures. Theoretical models and empirical studies investigating their implications are explored. The major statistical properties and reg...

Social Interactions: Theory and Empirics

What Role for Empirics in International Trade?

In the field of international trade, data analysis has traditionally had quite modest influence relative to that of pure theory. At one time, this might have been rationalized by the paucity of empirics in the field or its weak theoretical foundations. In recent years empirical research has begun to provide an increasingly detailed view of the determinants of trade relations. Yet the field as a...
