Japan's Fiscal Multipliers: Why Stimulus Fails After 1985 (Shocking Data)

Fiscal Multipliers in Japan: The Role of Unconventional Monetary Policy and Labor Market Slack

Alan J. Auerbach, Yuriy Gorodnichenko

Economists Alan J. Auerbach and Yuriy Gorodnichenko reveal a stunning truth about Japan's fiscal policy. Over the long run (1960-2012), government spending multipliers averaged 2.30—boosting the economy significantly, especially during recessions. But after 1985, everything changed. The multiplier collapsed to just 0.27, and even turned negative in some periods. Why? The study uncovers hidden culprits: zombie firms blocking resource flow, the Bank of Japan's implicit tightening threats, and misleading unemployment data that made policymakers think the economy was fine when it wasn't. Using innovative methods like state-dependent models and forecast error controls, the authors show that fiscal stimulus isn't a magic bullet—it depends on when and how you use it. Watch to learn why Japan's lost decades offer critical lessons for any economy facing stagnation.
