We examine how U.S. publicly listed firms' brand innovation is sacrificed when managers reduce marketing budgets in order to make short-term earnings targets. Using the newly available U.S. trademark dataset to measure the lifespan of new brands, we find that new brands' survival rate...

Using comprehensive patent lawsuit data from 2000 to 2014, we find that a stock portfolio consisting of firms involved in patent lawsuits provides significantly positive stock returns (between 0.56% to 1.02% per month) in the following year. We propose and examine several possible explanations...

We show that the similarity of a firm's technological expertise with other firms affects outcomes in the managerial labor market. Using each firm's patent portfolio to estimate its technological expertise, we find that its similarity in technological expertise with other firms is strongly...

We propose that general purpose technologies (GPTs) — a class of technologies that have pervasive impacts on the economy and spill over across countries — are a source of non-diversifiable technology risk in international stock markets. We construct an empirical GPT factor from patent data...

This paper uses deep learning and natural language processing (NLP) methods on the US patent corpus to evaluate their predictive power in estimating two measures of patent value: (i) investor reaction to patent announcements as measured in Kogan et al., 2017 and (ii) forward citations. While...

This paper empirically examines the informational role of start-ups' patenting activities in venture capital (VC) financing, based on comprehensive patent data for VC-backed firms in the U.S. from 1976 through 2005. We find that start-ups' patenting activities before receiving VC investment...

This paper empirically examines the effects of industrial and geographic innovations on firm-level profitability and stock returns due to spillovers. Using the data of U.S. patents and patent inventors, we propose empirical proxies for industrial and geographic spillovers and find a positive...

This paper examines how financial frictions and policy uncertainty jointly influence firms' investments in pollution abatement. Our data analyses suggest that financially constrained firms are less likely to invest in pollution abatement and are more likely to release toxic pollutants, with this...
