Coexistence with the Aging Society in Developing Economies


Since the latter half of the 1990s, it has been suggested that many developing countries are likely to face serious population aging problems while these economies are still underdeveloped and their preparations are insufficient. As the global interdependence of national economies has deepened, a socio-economic problem in one country has come to have a significant influence on other countries’ economies and its effects might easily spread around the world. The purpose of this research project is to present a series of basic analyses on an international cooperative framework that may offset the negative effects of population aging and enable the enjoyment of benefits from the so-called "population bonus" that may exist in developing economies with an abundant working population relative to its volume of dependents. We also aim to conduct analyses that examine fiscal consolidation or social security reforms as national measures. Utilizing a numerical Overlapping Generations (OLG) model, which includes regions that are different in demographic structure, we perform simulations to examine the effects of the following three types of policy measures on the patterns of international trade, capital flows, savings and economic growth: (1) domestic pension reforms in developed and developing economies; (2) foreign aid from regions with an already aged population compared to other regions, in which one is at the initial stage of yielding a population bonus and the other has merely plenty of young dependents; and (3) economic partnership programs between regions at different phases of the aging process.
