Essays in Corporate Finance

Abstract

Macroeconomic and institutional shocks are important drivers of firms' activities. In chapter one, I examine the role of patent litigation in affecting companies’ innovation. Studying a landmark Supreme Court decision, I show that an improvement in patent enforcement positively affects the innovation activity of corporations. In chapter two, I study the role of private equity in period of large financial turmoil. In the context of the 2008 crisis in United Kingdom, I show that private equity backed companies experienced a lower decline in investment than a control group of similar companies that were not related to private equity. This effect is explained by the ability of private equity to relax the financing constraints of the portfolio companies when access to credit markets is limited. In chapter three, I explore the role of sovereign securities held by banks in the propagation of a financial shock to the economy. Using detailed loan level data matching firms and banks in Italy, the paper finds that the shock to banks' sovereign portfolio caused by the Greek bailout (2010) was passed on to firms through a contraction in credit. The effects of this shock were particularly disruptive for smaller companies.
