We show a new way through which patent protection affects innovation. We show that patent protection may reduce the final goods producers' incentives for innovation in industries with imperfectly competitive input markets. The input market structure may play an important role in this respect.

Although regulatory authorities are putting more emphasis to the long-run effects of mergers and acquisitions due to their effects on innovation, several merger proposals have been challenged due to their adverse innovation effects. In a simple model with endogenous R&D investment, we show that...

We construct a new database by matching firm-level Compustat data to NBER patent data, for four 2-digit complex technology sectors. Whilst conventional regression estimators show that the stock market does recognise efforts at innovation, quantile regression analysis adds a new dimension to the...

This paper studies the question of whether and how an employee innovator should commercialize an innovation, when doing so within the firm is less costly than pursuing an outside venture, but risks expropriation by the firm. We show that a weaker chance of expropriation, interpreted as the...

This paper focuses on the innovation gap between countries in the Euro-Mediterranean (Euromed) area and its implications in terms of growth and convergence. Using a large set of innovation variables, we estimate a growth model à la Barro which shows that differences in innovation between...

We study innovation and R&D investments made from 2008 to 2010 by UK companies that were the targets of leveraged buyout (LBO) in previous years. We find that overall, LBO companies do not exhibit lower innovation and R&D investments than non-LBO companies during the crisis, with other things...

The relationship between exports and the propensity to innovate is an important issue for a developing economy. This article is dedicated to this question through the analysis of the first innovation survey of Tunisian firms. In particular, it distinguishes the propensity to innovate among three...

We examine how consumption externalities affect R&D activities by using a simple innovation-driven growth model where the sources of growth are both horizontal and vertical innovations. We show that if there are negative (positive) consumption externalities, the economy attains a higher (lower)...

In this note, we construct two theoretical models that analyze the relationship between inequality of access and rates of innovation as well as correlative data that show a negative correlation between income inequality and levels of innovativeness. Our two models suggest that unequal access to...
