Abstract
AbstractUsing listed Japanese firms, we examine changes in R&D investment decisions during periods of high economic policy uncertainty and politics uncertainty (EPU). We find that under high EPU, firms are more persistent in their previous R&D investment and reduce their responsiveness to sales growth, while the mechanism of EPU occurs mainly through fiscal policy. We also identify heterogeneities in ownership structure and find that high director ownership encourages R&D in firms with greater growth opportunities despite higher EPU. Moreover, Japanese directors suffer from the “quiet life problem,” which further reduces their incentive to change R&D investment during periods of EPU.
