When making decisions, agents tend to make use of decisions others have made in similar situations. Ignoring this behavior in empirical models can be interpreted as a problem of omitted variables and may seriously bias parameter estimates and harm inference. We suggest a possibility of...

In this study, we consider R&D collaboration networks as a mechanism that modifies knowledge flows in space, and hence as another source of interaction among regional innovation processes. Our objective is to understand the relative role of spatial neighbors and network neighbors on patenting...

One of the key assumptions in spatial econometric modelling is that the spatial process is isotropic, which means that direction is irrelevant in the specification of the spatial structure. On one hand, this assumption largely reduces the complexity of the spatial models and facilitates...

We show in this paper that spatial dependence and spatial heterogeneity matter in the estimation of the b-convergence process among 138 European regions over the 1980-1995 period. Using spatial econometrics tools, we detect both spatial dependence and spatial heterogeneity in the form of...

La teoría que explica la violencia homicida es nutrida. Algunas corrientes apuntan a causas objetivas, como la pobreza y las condiciones sociales, mientras otras proponen que la causan las empresas criminales. En el presente artículo se realiza un análisis espacial de la violencia utilizando...

The concept of «agglomeration economies» explains the existence of advantages derived from the concentration of population and activity. However, it does not explain the existence of spatially dynamic external economies. Network economies generated in networks of cities correspond to this last...

This study revisits the utility of gravity models in the analysis of the principal determinants of exports. Traditional cross-sectional models are improved by considering the effect of omitted variables and/or the dynamic of trade flows through the use of spatial econometric techniques and panel...

The aim of this paper is to analyze the consequences of spatial dependence on regional growth and the convergence process. Based on a sample of 92 European regions over the 1980-1995 period, we show that the unconditional ?-convergence model is misspecified due to the presence of spatial...

Whereas the process of integration economic is accentuated in Europe, regional integration dynamics of space seems to be a crucial issue. Reflexions engaged, in particular through the SDEC, aim at promoting a voluntarist policy of polycentric adjustment of European space. Thus we are led to...
