Asia and the Global Economy (Jan 2022)
Investigating how exchange rates affected the Japanese economy after the advent of Abenomics
Abstract
News of aggressive monetary easing by the Bank of Japan in late 2012 contributed to a 45 percent depreciation of the Japanese yen relative to the U.S. dollar. This paper investigates how the depreciation affected the Japanese economy. Exports responded much less than predicted, especially for sectors related to transportation equipment. Imports also responded less than predicted, and the sum of export and import elasticities are too small to meet the Marshall-Lerner condition. A depreciation raises returns for many Japanese stocks, with the response being largest for automobile stocks. A depreciation also raises aggregate Japanese stock returns by twice as much after 2013 as before. This indicates that responses that corporate Japan made to swings in the yen such as transferring production abroad have been good for profitability.
