Recent research on the secular decline of fertility in historical Europe has focused on cultural explanations in the wake of the European Fertility Project's failure to confirm demographic transition theory. Using the city of Riga in present-day Latvia as a case study, the essay provides initial estimates of nuptiality and fertility for resident language and religious groups in 1867 and 1881, and reviews the prospects of future work. Despite obstacles, Eastern Europe offers researchers an exceptional opportunity to test major cultural and economic hypotheses about the fertility decline because sustained ethnic diversity coexisted with economic development.  相似文献

This empirical study measures the prevalence and incidence of housing affordability problems in Canada in 1972, 1976, and 1983. It shows the affordability problem has not been improved by the major effort the Canadian governments made during the 1970s. Rent controls have not been adequate in reducing affordability problems. Moderate intervention in the housing market are not enough to help low income households attain affordable housing. The problem's resolution may require a major effort to stimulate housing supply, and by direct government involvement, adjustment in creating new methods and institutions for building and delivering housing services. Housing affordability problems will remain unresolved in the absence of major income redistribution programs.  相似文献
