This paper introduces heterogeneity of cross-technologies interactions into the double-differentiated R&D-based endogenous growth model. In this model new technologies appear continuously and older are outdated generating structural change. All technologies may interact with each other through...

Previous work suggests that research and development (R&D) tax credits increase R&D expenditure. We exploit the staggered adoption of state-level R&D tax credits in the United States to examine their effect on innovation itself. In particular, we consider ten commonly-studied patent...

According to theory, direct R&D grants should be used for projects with low private returns, high social returns and high risk. R&D tax credits, on the other hand, allow firms to choose projects freely according to their private returns. Building on the standard R&D capital model, I develop a...

This paper evaluates how R&D subsidies to the business sector are typically awarded. We identify two sources of ineffciency: the selection based on a ranking of individual projects, rather than complete allocations, and the failure to induce competition among applicants in order to extract and...

Many countries have introduced patent box regimes in recent years, offering a reduced tax rate to businesses for their IP-related income. In this paper, we analyze the effects of patent box regimes when countries can simultaneously use patent boxes and R&D subsidies to promote innovation. We...

We examine the impact of both R&D tax credits and direct R&D subsidies on Norwegian firms' patenting. Whereas direct subsidies are aimed at projects with low private and high social return, tax credits do not discriminate between projects or technologies. We find that both direct subsidies and...

We consider a setting where strategic behavior of r&d firms can lead to different types of a technology lock-in, permanent or temporary, in an eventually inferior technology. The simple setting with one incumbent and one potential entrant may lead to a wide variety of possible strategic regimes....

The impact of ICT (information and communication technology) on economic performance has been the subject of academic research for several decades, and despite the remarkable and significant innovation in computer technology, usage, and investments, only a small growth in productivity was...

The granting of publicly subsidized joint projects has become a popular policy instrument in Germany and other developed countries. However, little is known about how an emerging subsidization network affects the overall allocation process of further project grants. Employing a database that...

The effectiveness of R&D subsidies can vary substantially depending on their characteristics. Specifically, the amount and intensity of such subsidies are crucial issues in the design of public schemes supporting private R&D. Public agencies determine the intensities of R&D subsidies for firms...
