Regional Problems in a Common Market
After a long period of comparative neglect, the past twenty years have seen important developments in regional analysis. These developments came from two sources: intensified theoretical analysis of the economic problems of regions and increased attention given to regional issues by the policy-makers. The two lines of approach appeared intertwined in some earlier contributions, such as the British Report on the Location of Industry1 and the American Industrial Lo-
cation and Natural Resources,2 and this interaction has been maintained since, as witnessed, for example, by a recent study on Puerto Rican refinery-petrochemical-synthetic-fiber complexes3 or by the discussion of regional problems in the European Common Market.
