If the population of a given country evolves according to Gibrat'�s Law, its growth rate will be independent of its initial size. This short paper further investigates this empirical regularity by the application of a suitable panel unit root test and non-parametric methods. The evidence...

A re-assessment of Gibrat's Law in the context of country size is carried out in this paper. In addition, how similarly population is distributed in cities and countries is analyzed from a temporal perspective. Although evidence of Gibrat's Law is found, it is weaker than that previously...

This paper analyses the determinants of growth of American cities, understood as growth of the population or per capita income, from 1990 to 2000. This empirical analysis uses data from all cities with no size restriction (our sample contains data for 21,655 cities). The results show that while...

The aim of this paper is to analyse, through a theoretical model, the effects that the trade integration of two countries may have on industrial location, growth and welfare. The conclusions reached finally depend both on whether the import or the export costs are affected by the trade policies...

In this paper we present a model integrating characteristics of the New Economic Geography, the theory of endogenous growth and the economy of natural resources. This theoretical framework enables us to study explicitly the effect of “first nature causes” in the concentration of economic...

This paper analyzes the evolution of the size distribution of the stock of immigrants in the period 1960–2000. In particular, we are interested in testing the validity of two empirical regularities: Zipf’s law, which postulates that the product between the rank and size of a population is...

This paper analyses the determinants of growth of American cities, understood as growth of the population or of per capita income, from 1990 to 2000. This empirical analysis uses data from all cities with more than 25,000 inhabitants in the year 2000 (1154 cities). The results show that while a...

This paper reconsiders the evolution of the growth of American cities since 1790 in the light of new theories of urban growth. Our null hypothesis for long-term growth is random growth. We obtain evidence supporting random growth against the alternative of mean reversion (convergence) in city...

In this paper, we develop a new theoretical model that explains the forest transition not at a local, but at a worldwide level, in a trade liberalisation scenario. Our model has economic geography foundations: transport costs affect the distribution of firms between countries. We also introduce...
