Chapter 1: Innovation Diversification Under Policy Uncertainty

Using detailed data on patent grants and applications, I explore the effect of policy uncertainty on firms’ innovation strategies. I show that firms that invest in R&D tend to pursue more diversified strategies and are more likely to explore unfamiliar fields during periods of policy uncertainty. These findings hold after adjusting for possible sample-selection bias using variation from patent examiners’ historical approval rates, and after adjusting for potential endogeneity using …

Technological Diversity In Finance, Blake K. Rayfield

University of New Orleans Theses and Dissertations

The dissertation consists of two chapters on measuring firms technological profile. Patent data can be grouped into two primary generations.

We establish causality of board independence on innovation using a difference-in-difference approach that exploits an exogenous shock to board composition, namely, the mandate of a majority of outside directors on company boards by NYSE and NASDAQ in response to the passage of Sarbanes-Oxley Act in 2002. We further …
