This work shows how Japan escaped from the depression in its early stage. It illustrates a transmission mechanism of the macroeconomic stimulus package of currency depreciation, easy money, and fiscal expansion. As well, it argues that the key for economic recovery was currency depreciation and that expectations played a pivotal role in ending deflation and kick-starting economic recovery. Also contained here is an exploration of politico-economic interaction in the shaping of economic policy and the long-term consequences of policy actions such as departure from the gold standard and initiation of the government debt finance by the central bank. It is shown that the collapse of the international gold standard and the lack of governance of military spending resulted in a loss of fiscal discipline in the long run.
