An autoregressive model has been applied to the 1978 Cameroon World Fertility Survey data to test the fertility adaptation hypothesis of rural-urban migration. The fertility differential between rural-urban migrants and rural stayers is very small in Cameroon when compared with that of Korea and Mexico. However, the lack of fertility differentials between rural-urban migrants and rural stayers which are the result of the unique cultural and biosocial parameters of African fertility does not imply a weak fertility adaptation effect.

This paper compares fertility levels of Mexican internal migrants with United States immigrants from Mexico, in an attempt to shed light on the issues of selection and adaptation in immigration literature. The data show that U.S. immigrants from Mexico have similar levels of fertility to those of urban‐urban migrants in Mexico. Though somewhat speculative, the analyses suggest that some fertility adaptation does take place. New directions for research which would be of a less speculative nature are discussed.

This paper performs multiple regression analysis to identify a large number of determinants of commuting time and distance for Seoul residents using the 2 per cent public-use sample data tape of the 1995 Korean Population Census. Among the numerous findings, it is noted that commuting times and distances are longer for male workers, full-time salaried workers, workers with more education, home-owners and male workers in the prime earning years (over age 35). It is found that the household responsibility of childcare is an important factor for the shorter commuting of Korean married women.

The growth of an industry in a city has been explained by dynamic externality theories such as those by Marshall, Arrow and Romer, Porter, Jacobs and Storper. Each of these views describes a different mechanism by which the initial conditions for a particular industry in a city facilitate knowledge spillover extensive enough to promote productivity growth. This paper develops a model that distinguishes among these and applies it to Korean manufacturing industries. The empirical analysis concludes that productivity growth in Korea is more rapid when small firms from different industries compete, supporting theories by Jacobs and Storper. However, the impacts of specialisation and diversification vary substantially across major manufacturing industry sub-categories. Land use regulations such as greenbelt rates and excessive concentration control districts generally show significant negative effects on productivity growth.
