Isard’s vision of integrated modeling that was laid out in the 1960s book Methods of Regional Science provided a road map for the development of more sophisticated analysis of spatial economic systems. Some forty years later, we look back at this vision and trace developments in a sample of...

The System Dynamics methodology is used in this article as unifying approach in order to show how a number of theories about the performance of territories developed in the past 20 years can integrate the one with the other; to demonstrate this, a model of local economy coherent with these...

The persistence of disparities is one of the most striking features of regional development. We argue that movements of labour force, instead of being an always equilibrating mechanism, can also make persistent or even reinforce such inequalities. The most advanced regions are in fact generally...
