This paper investigates how the interactions between product differentiation, transport costs and urban costs determine spatial inequality in a general-equilibrium model. We shed light on the interrelation between different definitions of home market effect (HME) in literature. While the wages...

There is a large consensus among international institutions and national governments to favor urban-containment policies - the compact city - as a way to reduce the ecological footprint of cities. This approach overlooks the following basic trade-off: the concentration of activities decreases...

This paper considers the racetrack economic approach, where manufacturing activities are distributed continuously. We seek constant-access equilibria and show that smooth equilibrium distributions are always unstable for almost all transport cost functions, whereas agglomeration in 1 or 2 atomic...

We investigate how international trade and trade policy possibly affect the regional distribution of economic activities within a country involved in a process of economic integration. Our analysis reveals that the impact of decreasing international trade costs on the spatial distribution of...

What determines the spatial distribution of economic activity? And why is economic activity sometimes "lumpy", distributed in a core-periphery pattern in some countries? This paper uses new sub regional data on the spatial distribution of economic activity for a large cross section of countries,...

This paper presents the new dynamic spatial general equilibrium (DSGE) model – RHOMOLO, which is built to support the EU policy design by undertaking holistic, micro-founded and disaggregated policy impact assessment. The RHOMOLO model is based on the theories of general equilibrium,...

This paper discusses the interdependencies that exist between vertically-linked industries in the (Spence-)Dixit-Stiglitz model of monopolistic competition. The main objective is to develop a concept for quantifying the magnitude of sectoral coherence in models of the New Economic Geography. It...

This paper discusses a model of the New Economic Geography, in which the seminal core-periphery model of Krugman (1991) is extended by endogenous research activities. Beyond the common anonymous consideration of R&D expenditures within fixed costs, this model introduces vertical product...
