This paper examines the long‐term causal impact of Abenomics, a comprehensive policy package aiming to revitalise the Japanese economy. Using the Synthetic Control Method (SCM), the study assesses the effects of Abenomics across a variety of economic indicators. The findings reveal mixed impacts, with no evidence of Abenomics reducing budget deficits or boosting exports, but a positive effect on real GDP per capita paired with a reduction in the unemployment rate. The evidence regarding the effect on labor force participation rates is weaker, with primarily statistically insignificant increases observed. These results offer insights into the effectiveness of comprehensive policy interventions and provide lessons for policymakers globally in the midst of a global economic slowdown.
