The structures of social interaction affect individual behavior and economic performance in important ways. This leads us to ask: does the architecture of social interaction exhibit particular patterns and are these patterns stable over time? We examine interaction among economists by looking at...

Population Economics (PopEc) covers a number of topics in Economics, as well as in Demography, Labor Studies, Sociology, etc. For example, the economic determinants of population change and demographic behavior covers topics such as household formation, marriage and divorce, fertility, gender,...

We explore the relationship between collaborations in writing papers and the academic productivity of economists and, particularly, we describe the magnitude and intensity of co-authorship among economists. To that end, we employ interaction maps from Complex Systems methods to study the global...

This paper examines effects of academic networks in a Stackelberg differential game between journal editors and authors. Authors choose research papers to maximize satisfaction, while editors determine research quality to maximize journal reputation. Verifying the system for stability, results...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

This paper examines the small world hypothesis. The first part of the paper presents empirical evidence on the evolution of a particular world: the world of journal publishing economists during the period 1970-2000. We find that in the 1970's the world of economics was a collection of islands....
