We examine the reason why two opposing views on distressed banks' lending behavior in Japan's postbubble period have coexisted: one is stagnant lending in a capital crunch and the other is forbearance lending to low-quality borrowers. To this end, we address the measurement problem for bank balance sheet risk. We identify the credit supply and allocation effects of bank capital in the bank loan equation specified at the loan level, thereby finding that the parallel worlds, or the two opposing views, emerge because the regulatory capital does not reflect the actual condition of increased risk on bank balance sheets, while the market value of capital does. By uncovering banks' efforts to increase regulatory capital in Japan's postbubble period, we show that banks with low market capitalization, and which had difficulty in building up adequate equity capital for their risk exposure, decreased the overall supply of credit. Parallel worlds can emerge whenever banks are allowed to overvalue assets at their discretion, as in Japan' postbubble period.
