Business Cycle Accounting for the Japanese Economy

We conducted business cycle accounting (BCA) using the method developed by Chari, Kehoe, and McGrattan (2002a) on data from the 1980s--1990s in Japan and from the interwar period in Japan and the United States. The contribution of this paper is twofold. First, we find that labor wedges may have been a major contributor to the decade-long recession in the 1990s in Japan. Assuming exogenous variations in the share of labor, we find that the deterioration in the labor wedge started around 1990, which coincides with the onset of the recession. Second, we performed an alternative BCA exercise using the capital wedge instead of the investment wedge to check the robustness of BCA implications for financial frictions. The accounting results with the capital wedge imply that financial frictions may have had a large depressive effect during the 1930s in the United States. This implication is the opposite of that from the original BCA findings.
