Our aim is to explain how a small country can be viable as an international banking center (IBC). We build a model in which mobile investors choose between two banking centers located respectively in a small country and in a large country. These countries compete in two instruments, taxation and...

We study the effects of a decrease in trade costs on the spatial distribution of industry in a multi-regional economy, when a rise in the regional population of workers generates higher urban costs. When the number of cities is unaffected by falling trade costs, small cities become smaller for...

Lancasterian models of product differentiation typically assume a one-dimensional characteristics space. We show that standard results on prices and locations no longer hold when firms compete in a multi-characteristics space. In the location game with n characteristics, firms choose to maximize...

We address the fundamental question arising in economic geography: why do economic activities agglomerate in a small number of places? The main reasons for the formation of economic clusters involving firms and/or households are analysed: (i) externalities under perfect competition; (ii)...

Using a data set of highly cited researchers in all fields of science, we show that the gap in scientific performance between Europe, especially continental Europe, and the USA is large. We model the number of highly cited researchers in a sample of countries as a function of physical and human...

We re-examine the economic justification for the regulation of firms' spatial price policies. Existing analysis, by treating market structure as exogenous, loses an important trade-off. Discriminatory pricing is more competitive between incumbents but acts as a strong deterrent against entry....

This Paper studies the positive aspects of destination vs. origin principles of commodity taxation as well as tax harmonization, with an emphasis on the international implications of these measures when firms are mobile. We investigate the tax incidence of these two principles on price levels...

We investigate whether an aging population may challenge the supremacy of large working-cities. To this end, we develop an economic geography model with two types of individuals (workers and retirees) and two sectors (local services and manufacturing). Workers produce and consume; the elderly...

Armchair evidence shows that many industries are made of a few big commercial or manufacturing firms, which are able to affect the market outcome, and of a myriad of small family-run businesses with very few employees, each of which has a negligible impact on the market. Examples can be found in...

Paul Krugman has clarified the microeconomic underpinnings of both spatial economic agglomerations and regional imbalances at national and international levels. He has achieved this with a series of remarkably original papers and books that succeed in combining imperfect competition, increasing...
