Effects of Endogenous Longevity on Transitional Dynamics of Intergenerational Mobility

This paper explains the mechanism that causes the two motions of intergenerational mobility, monotonic motion and cyclical motion. Increasing longevity encourages incentives for education investment while decreasing transfers, which is the funding source for education. If longevity increases slowly, mobility increases monotonically. However, if longevity increases rapidly with economic development, mobility is cyclical owing to a largely decreasing transfer. This result is consistent with the empirical evidence in the literature on intergenerational mobility. In fact, China, where longevity increased rapidly, experienced a cyclical motion of mobility, whereas Norway, where longevity increased slowly, has experienced a monotonic motion of mobility.
