ABSTRACT
This study is an attempt to assess the impact of policy initiatives launched
by Japan’s new Prime Minister Shinzo Abe on Japan’s real GDP in his first
quarter in office. We use as a benchmark for measurement a counterfactual
estimate of GDP. Since the Japanese economy is also in the midst of
reconstruction from the 2011 Tohoku disaster in the first quarter of 2013， we
first estimate the counterfactual GDP which would have materialized in the
absence of that disaster. We will use a dummy variable method and the
statistical method proposed by Cheng Hsia and others. We check the validity
of these methods with regard to the Kobe earthquake of 1995， and then
estimate the post-disaster counterfactual GDP for the Tohoku disaster. We
measure the impact of government policies as the difference between the
actual and counterfactual GDP. By doing so， we conclude that government
policies have failed to lift Japan’s GDP to the expected level. Even with the
help of Abenomics， the gap remains in the rage of 3 to 13 trillion yen per year.
