WTO negotiations rely on tariff reduction formulas. It has been argued that formula approaches are of increasing importance in trade talks, because of the large number of countries involved, the wider dispersion in initial tariffs (e.g. tariff peaks) and gaps between bound and applied tariff...

In models of economic geography, plant-level scale economies and trade costs create incentives for spatial agglomeration of production into a manufacturing core and agricultural periphery, creating regional income differentials. We examine tax competition between national governments to...

We examine the consequences of increased economic integration between nations within a region. We adopt Krugman’s economic-geography model in which demand linkages can generate agglomeration of manufacturing activity. Manufacturing labour is assumed to be imperfectly mobile between countries....

Parallel imports are a significant academic and policy issue. Official investigations into the impact of parallel imports on music CD prices have reached widely conflicting conclusions. This note reports an event study on an international panel of changes in copyright law to permit or disallow...

How should the size and number of cities evolve optimally as population grows? Stripped of the constraints of geography itself, the setup of the New Economic Geography implies that de-agglomeration (or de- urbanization) is efficient. The number of cities increases while the size of each...

A stylized pattern of interindustry trade between developing and developed regions identifies the former as specialists in light manufactures and latter in heavy manufactures. Conventional explanations for this pattern rely on the factor proportions model, which is empirically suspect. This...

This paper presents a new theoretical framework to analyze=20 financial markets in an international context. We build a two-country=20 macroeconomic model in which agents are risk averse, assets are imperfect=20 substitutes, the number of financial assets is endogenous, and cross-border= =20...

This paper analyzes the genericity of bifurcations of one-parameter families of smooth (C1) vector fields that are embedded in an underlying multi-dimensional parameter space. Bifurcations with crossing equilibrium loci are called 'split bifurcations.' They include, for example, the pitchfork...

We study the indeterminacy of equilibrium in the Fujita-Krugman (1995) model of city formation under monopolistic competition and increasing returns. Both the number and the locations of cities are endogenously determined. Assuming smooth transportation costs, we examine equilibria in...
