The 2008 Nobel prize for economics was awarded to Paul Krugman for three papers - Krugman (1979, 1980, 1991). In this paper we illustrate that, indeed, these three papers are closely connected. We present - a summary of - the papers using a unified framework. Central in the discussion is the...

In explaining the uneven spatial distribution of economic activity, urban economics and new economic geography (NEG) dominate recent research in economics. A main difference between these two approaches is that NEG stresses the role of spatial linkages whereas urban economics does not do so. We...

With the completion of EMU, tax competition and, more in general, locational competition is high on the EU policy agenda. In contrast to the standard neo-classical reasoning, recent advances in the theory of trade and location have shown that tax competition does not necessarily lead to a race...

Based on a new economic geography (NEG) model by Puga (1999), we use the equilibrium wage equation to estimate two key structural model parameters for the NUTS II EU regions. These estimations enable us to come up with an empirically grounded free-ness of trade parameter. In line with NEG...

Stimulating firms to become exporters is of interest to policy makers, as exporters are in general more productive than non-exporters. However, selecting high export potentials is difficult in practice. The contribution of this paper is to characterize and identify these (high) export...

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...

In this paper we want to shed some light on the empirical relevance of the new economic geography. Using one of the central features of the core new economic geography models, namely that wages have the tendency to fall the further one moves away from centres of economic activity, we investigate...

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...
