Modeling a micro-structure of agglomeration economies, this article derives a second-best benefit evaluation formula for urban transportation improvements. Without explicitly modeling the sources of agglomeration economies, Venables (JTEP 2007) investigated the same problem. This article...

Regional labor markets are characterized by huge disparities of unemployment rates. Models of the New Economic Geography explain how disparities of regional goods markets endogenously arise but usually assume full employment. This paper discusses regional unemployment disparities by introducing...

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...

The present paper describes the construction and first empirical application of the TIGER model (TIGER is an abbreviation of "Transport and Infrastructure General Equilibrium model for Regions"). The TIGER model belongs to the group of regional CGE models, applying a mix of conventional...

This paper posits a new approach to the 'wage equation' of the New Economic Geography (NEG). On one side, it is shown that the NEG provides a spatial explanation of marginal costs, instead of wages. On the other side, and focusing on the statistical properties of the data, it is explained why...

The present paper describes the modelling of regional labour markets in the newly developed dynamic spatial general equilibrium model RHOMOLO, where the labour market equilibrium is determined by firms' labour demand, a wage-curve determining unemployment, and interregional labour migration. The...

The paper asks whether subsidies aiming to redistribute economic activity across regions can be justified with the welfare argument. Moreover, different tax systems are compared with respect to the size of the subsidy needed for achieving a certain spatial distribution of economic activity, and...
