In a world of globalisation, it is tempting to foresee the 'death of distance' and, once the impediments to mobility have declined sufficiently, to wait for the predictions of the neo-classical theory of factor mobility to materialise. According to this theory, production factors respond to...

By its very nature, transport is linked to trade. Trade being one of the oldest human activities, the transport of commodities is, therefore, a fundamental ingredient of any society. People get involved in trade because they want to consume goods that are not produced within reach. The Silk Road...

We propose a general model of monopolistic competition, which encompasses existing models while being flexible enough to take into account new demand and competition features. Using the concept of Frechet differentiability, we determine a general demand system. The basic tool we use to study the...

We combine spatial and monopolistic competition to study market interactions between downtown retailers and an outlying shopping mall. Consumers shop at either marketplace or at both, and buy each variety in volume. The market solution stems from the interplay between the market expansion...

It is not so long ago that policy makers thought that excessive regional disparities would disappear automatically in the long run. Arbitrage possibilities arising from competition and factor mobility were expected to induce a more than average growth performance in lagging regions. Having the...

New economic geography focuses on the impact of falling transport costs on the spatial distribution of activities. However, it disregards the role of technological innovations, which are central to modern economic growth, as well as the role of migration costs, which are a strong impediment to...
