This research develops a model to identify the rate of employment growth and volatility of each industry in an open economy and applies this model to 15 manufacturing industries of Puerto Rico, using ...22-year employment time series data from 1960 to 1981. The estimated parameters of emplyment, growth and risk for each industry, in addition to other existing instruments, are used as an additional aid in identifying a desirable group of industries for island planners to pursue efforts toward employment stability and growth.
A review of the geographic distribution of the 5 million foreigners resident primarily in the urban areas of the Federal Republic of Germany is presented. "Economic trend surface and mixed space-time ...interaction models were chosen to analyse the changing distribution from 1964 to 1981." The results suggest that the settlement of foreigners in the 1960s was primarily influenced by job opportunities, whereas immigrants in the 1970s were more spatially diffused down the urban hierarchy. In 1981, "first-order spatial and temporal interaction or contagion effects are significant in determining the settlement pattern. The general south to north latitudinal settlement trend is weakening over time as migration responds less to distance (intervening opportunity) and more to local economic factors, immigration legislation, family reunification, and local contagion effects."

Studies on the migration of professionals to the United States have focused largely on the supply factors. This paper departs from this approach to assess whether the demand factors may not be the ...real determinants. The authors attempt to (1) estimate the flow of south Asian nationals entering the US labour market on a permanent basis from 1968 to 1981, and (2) Consider the major determinants of this immigration and the impact on both the US and south Asian economies.
