Business uncertainty and investment: Evidence from Japanese companies

This study, using data from a representative quarterly business survey in Japan, constructs measures of business uncertainty, presents empirical findings about the time-series properties of business uncertainty measures, and analyzes the relationship between these measures and investments. The results show, first, that business uncertainty heightened at the time of the collapse of Lehman Brothers, but the effect of an increase in the consumption tax rate on business uncertainty was small. Second, manufacturing and small companies tend to face higher business uncertainty than non-manufacturing and large companies. Third, we detect a negative association between business uncertainty and investments.
