Effectiveness of Credit Guarantees in the Japanese Loan Market

From 1998-2001, the Japanese government, in an effort to stimulate the flow of funds to the small business sector, implemented a massive credit guarantee program that was unprecedented in both scale and scope. Because the program was accessible by nearly every small firm we are able to clearly identify the policy effect. The program, therefore, presents a unique opportunity to determine if government intervention can improve the efficiency of credit allocation among bank-dependent small businesses. Utilizing a new panel data set of Japanese firms, which covers the implementation period of the program, we empirically test the theoretical predictions of Mankiw's (1986) adverse selection model. The model of credit markets under asymmetric information allows us to investigate whether government credit programs do more to stimulate small business investment, or serve to worsen the adverse selection problems prevalent in credit markets. We find evidence consistent with the former hypothesis. Specifically, we find that (1) program participants significantly increase their leverage, especially their use of long-term loans, and (2) with the exception of high-risk firms, become more efficient.
