Haavelmo's seminal 1943 paper is the first rigorous treatment of causality. In it, he distinguished the definition of causal parameters from their identification. He showed that causal parameters are de fined using hypothetical models that assign variation to some of the inputs determining...

Tax competition for a mobile factor is different in 'new economic geography settings' compared to standard tax competition models. The agglomeration rent which accrues to the mobile factor in the core region can be taxed. Moreover, a tax differential between the core and the periphery can be...

This paper studies the social desirability of agglomeration and the efficiency arguments for policy intervention in a simple, analytically solvable ?new economic geography? model with two trade integrating regions. The location pattern emerging as market equilibrium is ?bubbleshaped?, i.e. it...

The deterioration of the income and employment position of unskilled workers in the OECD area since the 1980s is a well-documented fact. The debate about the causes of this development is dominated by two competing hypotheses, "North-South Trade" or "globalisation" and technological progress....

This paper presents a simple, analytically solvable Chamberlinian agglomeration model. As in the canonical core-periphery (CP) model, two agglomerative forces are at work. However, the present model exhibits a 'pitchfork bifurcation' rather than the 'tomahawk bifurcation' of the CP model.

This paper uses a two country trade and geography model of monopolistic competition to study the effects of wage policies and social policies on the location of industry. It is first shown that a union wage push in one of two otherwise identical countries induces a relocation of firms which...

The core-periphery model by Krugman (1991) has two 'dramatic' implications: catastrophic agglomeration and locational hysteresis. We study this seminal model with CES instead of Cobb-Douglas upper tier preferences. This small generalization suffices to change these stark implications. For a wide...

Entrepreneurs who decide to enter an industry are faced with different levels of effective entry costs in different countries. These costs are heavily influenced by economic policy. What is not well understood is how international trade affects the government incentive to impact on entry costs,...
