Fundamental to regional science is the subject of spatial interaction. GeoComputation - a new research paradigm that represents the convergence of the disciplines of computer science, geographic information science, mathematics and statistics - has brought many scholars back to spatial...

We describe a spatial duopoly in a Hotelling model with quadratic transportation costs where consumers are distributed according to a symmetric density whose degree of concentration is variable. By solving the two-stage game in prices and locations as a function of the concentration index, we...

In this paper we perform a simulation procedure of testing models for journeys to work. The testing regime is carried out on a number of such models, mainly within the class of gravity models. We test the models on synthetic populations constructed from an aggregated set of a large number of...

In recent years we can observe a surge of interest among academics as well as regional policy makers in the phenomenon of geographical clustering of high-technology firms. In this study, we investigate whether agglomeration forces do have an impact on the innovative performance of a collection...

The analysis of regional income and productivity differences in the European Union (EU) has some tradition. The theoretical framework of most empirical studies on these subjects is the neoclassical growth model. Thus, research has focussed on convergence of income and productivity among EU...

The productivity generated by capital goods is not uniform, specially over the time. The productivity obtained from phisical goods is minor than one generated by new capital goods, or quality capital goods. It seems that the difference between both kinds of capital stems from the fact that...

Previous work in the demand for freight transportation has focused in the rail-truck substitution problem, leaving aside the prior own-account versus third-party trade-off, often found in transportation decision-making. The purpose of this paper is to analyze shippers’ behavior relative to...
