Commonly used industry classifications do not reliably predict stock co-movement because companies change their core structure quickly relative to the slow and haphazard updating of widely used subjective industry classifications. We construct an objective industry classification that clusters...

The aim of this paper consists of valuating a real biotechnology firm that is based on a portfolio of several drug development projects at different phases. They are patentprotected R&D projects and their values are obtained by implementing an extension of the real options approach in Schwartz...

When innovation is cumulative, patent protection on early inventions can generate holdup problems if later complementary patents are owned by different firms. Consistent with the property rights literature, we show that shareholder ownership overlap across firms with patent complementarities...

Firms in younger labor markets produce more innovation. We establish this by instrumenting the current labor force with historical births in each local labor market in the United States. Analyses of firms and inventors allow us to rule out unobservable heterogeneity across local labor markets...

Corporate innovation propels both company performance and economic growth. Yet, measuring corporate innovation proves to be challenging, leading researchers to rely on a variety of different signals, such as reported R&D expenditures, patent citations and new product announcements. I posit that...

We analyze, theoretically and empirically, the implications of salience on innovation announcements in the biopharmaceutical industry. We hypothesize that equity market investors are more likely to pay attention to an innovation announcement that is more salient: thus, investors pay more...

We document high economy-wide correlations between the Equity Risk Premium (ERP) and the aggregate volume (rho=-0.69) and value (rho=-0.75) of patenting activity by public firms in the United States over the 1977-2018 period, contradicting Schumpeter's (1939) opportunity-costs hypothesis of...

Schumpeterian arguments of “creative destruction” predict that innovation is countercyclical. However, empirical findings demonstrate the contrary. We apply corporate finance principles to macro- and innovation economics and propose a “hurdle-rate theory of inventive procyclicality”....

We analyze the impact of decreases in available lending resources on quantitative and qualitative dimensions of firms' patenting activities. We thereby make use of the European Banking Authority?s capital exercise to carve out the causal effect of bank lending on firm innovation. In order to do...

I construct a new proxy for Tobin's q that incorporates the replacement cost of patent capital. This proxy, PI (physical plus intangible) q, explains up to 62% more variation in investment than other proxies for q. Furthermore, investment is more sensitive to PI q than to other proxies for q....
