We distill the main insights from recent trade models on firms responses to globalisation. Our primary aim is to assess the economic impact and the welfare implications of the resulting reallocation of resources across firms and countries. In sodoing, we bring theory into life through the...

We investigate where cities are located in a spatial economy and why they tend to get "locked-in" at particular sites. Building on Fujita and Krugman (1995) we show that geography and/or transportation technology must exhibit some "non-smoothness" for cities to possibly become "locked-in" in...

This paper explores the interplay between commodities’ transportation costs and workers’ commuting costs within a general equilibrium framework `a la Dixit-Stiglitz. Workers are mobile and choose a region where to work as well as an intraurban location where to live. We show that a more...

We develop a two-region population growth model of economic geography and show that a process of urbanization has a substantial impact on the evolution of manufacturing real wages. Whereas real wages decline as the population increases when the spatial structure of the economy is fixed, they...

We extend Krugman's (1980) two-country two-sector model to a setup with arbitrary numbers of countries and sectors. The extended model predicts an adequately defined "home market effect" only after controlling for cross-country differential accessibility through a theory-based linear filter. We...

In this paper, based on the cyclic scheduling formulation of Schilling and Pantelides [22], we propose a continuous time mixed integer linear programming (MILP) formulation for the cyclic scheduling of a mixed plant, i.e. a plant composed of batch and continuous tasks. The cycle duration is a...

The objective of this paper is to apply different welfare approaches to the canonical model developed by Krugman, with the aim of comparing the only two possible market outcomes, i.e. agglomeration and dispersion. More precisely, we use the Pareto criterion, the compensation criteria put forward...

We investigate the spatial distribution and organization of an imperfectly competitive industry when firms may choose to operate more than a single production unit. Focusing on a short-run setting with a fixed mass of firms, we fully characterize the spatial equilibria analytically. Comparing...

In the last ten years the space issue, i.e. the study of the role played by space in economic phenomena, has attracted a lot of interest from many economic fields. The combination of increasing returns, market imperfections, and trade costs creates new forces that, together with factor...

We propose a model where imperfect matching between firms and workers on local labor markets leads to incentives for spatial agglomeration. We show that the occurrence of spatial agglomeration depends on initial size differences in terms of both number of workers and firms. Allowing for dynamics...
