Do Borrowing Constraints Matter? An Analysis of Why the Permanent Income Hypothesis Does Not Apply in Japan

Working Paper: NBER ID: w12330

Authors: Miki Kohara; Charles Yuji Horioka

Abstract: We use micro data on young married households from the Japanese Panel Survey of Consumers in order to analyze the importance of borrowing constraints in Japan. We find (1) that 8 to 15 percent of young married Japanese households are borrowing-constrained, (2) that household assets and the husband's educational attainment are the most important determinants of whether or not a household is borrowing-constrained, and (3) that the Euler equation implication is rejected for both the full sample and for the subsample of unconstrained households. These results suggest that the life cycle/permanent income hypothesis does not apply in Japan and that the presence of borrowing constraints is not the main reason why it does not apply.
