We assess the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function … efficiency of its innovation system is inversely u-shaped. Regions dominated by large establishments tend to be less efficient …

networks of four selected regions are based on information on patent applicants and inventors. Count data regressions show … positive effects on innovation of both the total number of relations and of access to a larger knowledge base.

A multi-stage model on the course of war is presented: Individual battles are modeled as private value all-pay auctions … with asymmetric combatants of two opposing teams. These auctions are placed within a multi-stage framework with a tug-of-war … models of militarized conflicts, yields new theoretical justification for existing empirical findings with respect to war, and …
