The author considers the impact of economic growth on regional differences in internal migration in Japan since World War II. "During the rapid economic growth period from the latter half of the 1950s to an early part of the 1970s, the number of migrants to metropolitan areas from other areas increased continuously. During the slow economic growth period from an early part of the 1970s to the present, however, the volume of internal migration has been decreasing mainly because of the decline in the number of in-migrants to metropolitan areas."

"The purpose of this paper is...to build a simultaneous estimation model of fertility, child quality, wife's labor supply and female wage, and to test the applicability of this model using time-series data from postwar Japan." The results imply "that fertility and employment have generally been [an] alternative behavior for... Japanese women; that their behavioral choice has depended on economic conditions; and that the quantity and quality of children have been substitutes." (SUMMARY IN JPN)
