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...

When the preference over intertemporal consumptions is of CIES type and human capital enters the production function in a secific way, we show that the optimum population growth rate is exactly the subjective discount rate in an infinite-horizon Ramsey Model.

This paper contributes to the debate about the appropriate efficiency rule for the provision of a firm-augmenting public input. This debate is caused by the dissatisfaction of Kaizuka-rule, i.e. a Samuelson-type condition for public inputs, in the long run. Therefore the applicability of...
