We examine whether the high cash ratio and the secular increase in cash holdings of U.S. firms are driven by healthcare and technology industries. We find that these two industries have significantly increased their cash holdings from 1980 to 2015. It is only in these two industries that firms...

In response to technological change, U.S. corporations have been investing more in intangible capital. This transformation is empirically associated with lower leverage and greater cash holdings, and commonly explained as a precautionary response to reduced debt capacity. We model how firms'...

While recent literature has focused on explaining the determinants of green innovations, it is not well understood how such innovations affect performance. To analyse the relationship between green innovation and performance, new industry-level panel data were exploited: these include 12 OECD...

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 focuses on the relationship between firms' technological capabilities and different forms of cooperation for innovation by combining the analysis of both micro and meso levels, i.e. the level of the firm and of the geographical region. Our findings, based on the Fourth UK Community...

Improvements in productivity are necessary to effectively increase economic growth in the long term. The literature emphasizes a positive correlation between firm-level innovation and productivity gains. It is unsurprising, then, that policy makers and researchers widely acknowledge that...

Why do some innovators freely reveal their intellectual property? This empirical puzzle has been a focal point of debate in the R&D literature. We show that innovators may share proprietary technology with rivals for free - even if it does not directly benefit them - to slow down competition. By...

In this paper, we develop a new dynamic model of optimal investments in R&D and manufacturing for a technological leader competing with a large number of identical followers on the market of a technological product. The model is formulated in the form of the infinite time horizon stochastic...

I use U.S. manufacturing industry data to estimate a system of three equations implied by a model of R&D-induced growth in steady state. These three equations relate R&D intensity to patenting, patenting to technological progress, and technological progress to economic growth. In each case, I...
