Application of Keynesian theory and new economic geography in Portugal. An alternative analysis

This work aims to test the Verdoorn Law, with the alternative specifications of (1)Kaldor (1966), for five Portuguese regions (NUTS II) from 1986 to 1994. It is intended to test, even in this work, the alternative interpretation of (2)Rowthorn (1975) of the Verdoorn's Law for the same regions and periods. The results of this work will be complemented with estimates of these relationships to other sectors of the economy than the industry (agriculture and services sectors) and for the total economy of each region. This work aims, yet, to study the Portuguese regional agglomeration process, using the linear form the New Economic Geography models that emphasize the importance of spatial factors (distance, costs of transport and communication) in explaining of the concentration of economic activity in certain locations. In a theoretical context, it is intended, also, to explain the complementarily of clustering models, associated with the New Economic Geography, and polarization associated with the Keynesian tradition, describing the mechanisms by which these processes are based.
