Investor Protection, Stock Liquidity, and Capital Structure

Abstract

This paper investigates empirically the impact of stock liquidity and investor protection on corporate capital structure. We predict that stock liquidity has a significantly negative impact on firm leverage and this negative impact is stronger in a country where the investor protection is strong. The sample consists of 2,203 firms listed in the UK, Germany, France, and Italy over the period from 2009 to 2018. Using a firm fixed effects model, we find evidence supporting our prediction. Our results are robust when we use a random effects model model, or when we employ an alternative measure of investor protection. Additionally, we find that an exogenous event that reduced the investor protection could dampen the negative impact of stock liquidity on firm leverage. Our paper suggests that future studies should consider the effects of factors related to the level of investor protection when investigating the relationship between stock liquidity and firm characteristics, such as firms’ default risk.
