“Heard the News? Environmental Policy and Clean Investments" | Joelle Noailly

Abstract

This study aims to construct various novel newspaper-based indexes of US environmental policy and to examine how they relate to clean investments. Extracting text from ten leading US newspapers over the last three decades, we use text-mining algorithms to build 1) a general index of US environmental policy history, 2) topic-specific components of environmental and climate regulations. We verify the added-value of these indexes by examining whether they capture meaningful policy shocks and how they are associated with proxies for clean investments, such as cleantech venture capital deals and stock returns. Our study shows that a lot of substantial information on environmental policy can be extracted from newspaper articles, providing promising avenues for future research.
