This paper studies how the assignment of patents as collateral determines the savings of firms and magnifies the effect of innovative rents on investment in research and development (R&D). We analyse the behaviour of innovative firms that face random and lumpy investment opportunities in R&D....

This paper examines Total Factor Productivity (TFP) and knowledge flows, using international patent data. The result is a measure of technology that isolates sources of innovation and their contributions to domestic TFP. Within-industry innovation enhances domestic productivity, and domestic...

We propose a new measure of the economic importance of each innovation. Our measure uses newly collected data on patents issued to US firms in the 1926 to 2010 period, combined with the stock market response to news about patents. Our patentlevel estimates of private economic value are...

This working paper reviews recent empirical evidence on large firms and nonproductive strategies that hinder creative destruction and reallocation. The focus is on three types of nonproductive strategies: political connections, nonproductive patenting, and anticompetitive acquisitions. Across...

Industrial houses and governments of different countries and groups spend a sizeable amount of their earnings upon research and development activities to create new products and obtain patents for them. The short-run motive is to get patents, and the long-run motive is to influence income growth...

We study the relationship between patents and actual product innovation in the market, and how this relationship varies with firms' market share. We use textual analysis to create a new data set that links patents to products of firms in the consumer goods sector. We find that patent filings are...

In recent years, a large body of empirical research has investigated whether the predictions of secondgeneration growth models are consistent with actual data. This strand of literature has focused on the longrun properties of these models by using productivity and innovation data but has not...

How do political connections affect firm dynamics, innovation, and creative destruction? We extend a Schumpeterian growth model with political connections that help firms ease their bureaucratic and regulatory burden. The model highlights how political connections influence an economy's business...

Do political connections affect firm dynamics, innovation, and creative destruction? We study Italian firms and their workers to answer this question. Our analysis uses a brand-new dataset, spanning the period from 1993 to 2014, where we merge: (i) firm-level balance sheet data; (ii) social...
