We analyze the equilibrium and the optimal resource allocations in a monocentric city under monopolistic competition. Unlike the constant elasticity of substitution (CES) case, where the equilibrium markups are independent of the city size, we present a variable elasticity of substitution (VES)...

An objective ranking of economics departments worldwide in terms of graduate education is derived. The central idea is that the value of a department is the sum of the values of its PhD graduates, as reflected in the values of their current employing departments. The scores are thus derived as...

This paper analyses and compares the dynamics of agglomeration in Portuguese and Irish manufacturing industries between 1985 and 1998 implementing Dumais, Ellison and Glaeser (2002) methodology. Using comparable and exhaustive micro-level data sets, we find that s industries tend to be subject...

In a model of horizontal product differentiation, we show that local monopolies may exist under free entry when capital is perfectly mobile. In contrast both with the situation of restricted entry and with the zero-profit approach to free entry outcomes of Salop (1979), the unit profit rate of...

This paper focuses on two distint facets of globalization: the decrease in the trade costs of goods and the decline of communication costs between headquarters and production facilities within firms. When the unskilled have about the same wage in the two regions, the decrease of these costs...

In modern economies, the amount of profits distributed to shareholders is far from being negligible. We show that the way they are distributed among agents matters for the space-economy. For example, the existence of mobile rentiers is sufficient to make the symmetric configuration unstable for...

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. We show that high and low trade costs imply that all regions involve a positive share of the...

The purpose of this paper is twofold. First, we present an alternative model of agglomeration and trade that displays the main features of the recent economic geography literature while allowing for the derivation of analytical results by means of simple algebra. Second, we show how this...
