Demographic aging and growth: towards an economic definition of aging.

Summary Faced with the catastrophic nature of economic and social analyses of the consequences of demographic aging, we have undertaken to demonstrate the existence of a positive link between contemporary demographic aging and economic growth. The ambition of this work is to support the relevance of this statement with two arguments. First, that of a positive link between human capital and longer life expectancy, which is included in a concept that we have named -economic aging- whose purpose is to measure biological and professional life expectancy. Secondly, we show through the development of a theoretical model combining wage and productivity profiles and human capital accumulation, that the type of human capital accumulated is an important explanatory component of permanent cessation of activities, and of the functioning of the labor market.
