How economic policy uncertainty affects the cost of raising equity capital : evidence from seasoned equity offerings

Abstract

Economic policy uncertainty (EPU) increases the cost of raising equity capital, especially when the economy is weak. A one standard deviation increase in the EPU index developed by Baker, Bloom, and Davis (2016) is associated with a 43 basis point increase in the price discount of seasoned equity offerings (SEOs) during the 2000−2014 period. The cross-sectional analysis shows that the EPU effect on SEO discounts is stronger for firms with greater dependence on government spending, less informative stock price, or a smaller EPU beta. Moreover, there are fewer SEO activities in periods when there is a high degree of policy uncertainty.
