Along with the oil price, concerns about the security of energy supply have soared once again in recent years.

Large cities (central places) excessively export to smaller cities in their surrounding hinterland. Using Japanese inter-city trade data, we identify a substantial centrality bias: Shipments from central places to their hinterland are 50%-125% larger than predicted by gravity forces. This upward...

The paper analyses how context and time dependent factors determine the impulse of R&D subsidies on firm behavior with respect to private R&D expenditures. Based on data from the German R&D survey, we combine propensity-score matching with a difference-in-difference-estimator in order to measure...
