We present estimates of a model of economic growth that highlights the positive effects of demographic change during 1960-95. We also show how Ireland benefited from lower fertility in the form of higher labor supply per capita and how Taiwan benefited through increased savings rates. We emphasize, however, that the realization of the potential benefits associated with the demographic transition appears to be dependent on institutions and policies, requiring the productive employment of the potential workers and savings the transition generates. Economic projections based on an "accounting" approach that assumes constant age-specific behavior are likely to be seriously misleading. ER -
