An economic interpretation of suicide cycles in Japan

Suicide rates in Japan have increased dramatically in recent years, making. Japan’s male rate the highest among developed economies. This study revises the standard economic model of suicide to accommodate Japan’s experience, focusing on the change in human capital for the unemployed. We then use the new model and de-trended data to empirically investigate the relationship between the suicide cycle and the unemployment cycle. Unlike previous aggregate time series studies, we find that the relationship between the suicide rate and the unemployment rate is significantly and robustly positive for both males and females even after controlling for several social variables.
