How Does Policy Uncertainty Affect Investments?

How Does Policy Uncertainty Affect Investments? In this episode, university professors Kate Holland and Veljko Fotak explore academic research on the impact of policy uncertainty on investment decisions, markets, and firms. The episode underscores that high levels of policy uncertainty tend to depress corporate investment, hiring, and economic growth, as firms delay major expenditures.
