In the European Union, energy markets are increasingly being liberalized. A case in point is the European natural gas industry. The general expectation is that more competition will lead to lower prices and higher volumes, and hence higher welfare. This paper indicates that this might not happen...

In contrast to empirical evidence, recent theories of cross-border mergers and acquisitions (M&As) assume perfect knowledge transfers – from high to low productivity firms – between acquirer and target. Using the Melitz (2003) model of heterogeneous firms, we develop a matching model of...

Lumpiness of production factors within a country might overturn the predictions for the structure of trade by the factor-abundance (HO) model. Trade patterns, as predicted by this model, can both be magnified or reversed by uneven concentration of production factors within a country. Cities are...

After World War II, town twinning became popular, notably in Germany. This was mainly a reaction to the war experience, and it was aimed at creating renewed international understanding and co-operation between German cities and cities in other countries. The contacts created by town twinning...

China’s Hukou system poses severe restrictions on labor mobility. This paper assesses the consequences of relaxing these restrictions for China’s internal economic geography. We base our analysis on a new economic geography model. First, we obtain estimates of the important model parameters...
