Public investment and business cycles: The case of Japan

This paper examines the effect of public investment on macroeconomic fluctuations in Japan by comparing the effects of central and local government investments. Impulse response functions show that central government investments slightly but persistently stimulate industrial production, while local government investments have no positive impact on business cycles. In terms of policy effectiveness, these results suggest that the Japanese government should not employ local public sector investments as a policy instrument for economic stabilization.
