Persistence of income shocks and consumption inequality: A case in Japan

  • Tomoaki Yamada

    ()

    (Meiji University)

The present study investigate the relationship between the persistence of uninsurable income shocks and consumption inequality over a household's life cycle in Japan. Using a life cycle model with incomplete asset markets and calibrated parameters for the Japanese economy, we quantitatively show that moderate persistence of shocks generate a nonlinear consumption inequality profile over the life cycle. The moderate persistence of shocks well replicates the pattern of consumption inequality in Japan.
