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...

In this paper, we offer an explanation why globalization (falling trade costs) may increase the government incentive to block foreign takeover of domestic firms and increase its incentive to allow mergers among national firms. This creation of `national champions' occurs not only because the...

The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We develop and quantify a novel framework to address this question at three...

We develop a new general equilibrium model of monopolistic competition with heterogeneous firms, variable demand elasticity and multiple asymmetric regions, in which trade integration induces wage and productivity changes. Using Canada-US interregional trade data, we structurally estimate a...

It is uncertain whether the fundamental ?home market effect? (HME) generalizes from a two-country model to a more realistic setting with multiple countries. We present a three-country version of the seminal model by Krugman (1980) and analyse under which circumstances the HME is present once...

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...

Governments in several countries have recently spent considerable effort to defend domestic firms against acquisition attempts from abroad and instead favoured mergers among national firms. In this paper we offer an explanation why globalization can reinforce the case for promoting national...

Entrepreneurs who decide to start a business are faced with different levels of effective entry costs in different countries. These costs are heavily influenced by economic policy through entry regulation and subsidies. In this paper we present a two-country general equilibrium model with...
