Long-Run Relationship between Consumption and Income in Japan: Tests of the Deterministic Cointegration Restriction

This paper reexamines two versions of the permanent income hypothesis derived from R. E. Hall (1978, J. Polit. Econ.86, 971–987) and R. G. King, C. L. Plosser, J. H. Stock, and M. W. Watson (1991, Amer. Econ. Rev.81, 819–840) using Japanese quarterly data. The main focus is on the relationship between stochastic and deterministic trends of consumption and income. It is found that the deterministic cointegration restriction implied by the two models is strongly rejected in Japan in contrast to the U.S. result, and the rejection of King et al.'s model depends on the existence of a trend break. This finding suggests that the postwar Japanese economy experienced the change in a steady state path considered by the neoclassical growth model. J. Japan. Int. Econ., June 2002, 16(2) pp. 253–278.
