r&d

The paper studies endogenous growth driven by an expanding variety of
product where lenders limit credit up to the collateralizable value of existing
patents.

Using a sample of Spanish firms, the authors test for differences across agencies and industries in research and development subsidy programs. Results suggest that firms in the same industry face different hurdles to participate in different agencies programs, that participation patterns may reflect a combination of agency goals, and that patterns differ across high-tech and low-tech industries.

The authors develop a model describing the dynamic behavior of individual heterogeneous firms that explains why research and development effort is strongly related to productivity and patenting yet essentially unrelated to firm size or growth.

Tthe effectiveness of a public innovation policy aimed at stimulating private R&D investment is explored. The research question is whether public funding increases the total spending on research or merely displaces funding from other
sources.

The paper measures scientific influence by means of citations to academic papers. Overall the results suggest that knowledge spillovers in basic science research are important, but are circumscribed by field and by intrinsic relevance.

The paper investigates the positive and normative effects of private information on research and development (R&D) activities. Results indicate that if the social planner is sufficiently impatient, a failure of information aggregation makes aggregate equilibrium expenditure in R&D on average too low with respect to the social optimum.

An attempt to contribute to the empirical analysis of the causal relationship between investment and performance, the study examines the interaction between a number of financial indicators represented by investments in research and development and tangible capital and a number of performance variables. Empirical results are
based on a large panel data set of Swedish manufacturing firms over the period 1992-2000.

The paper compares the contribution of research and development to innovation in terms of the various innovation output measures provided by the third Community Innovation Survey (CIS 3) for
French manufacturing firms and in terms of accounting for interindustry innovation differences.

Using the ENTICE model, the author analyzes the effectiveness of government subsidies to climate-friendly research and development (R&D) projects. While R&D subsidies do lead to significant increases in climate-friendly R&D, this R&D has little impact on the climate itself.

The study analyses how public research and development (R&D) financing impacts companies. The main goal is to study whether public and private R&D financing are substitutes or complements, and whether this impact differs between financially constrained and unconstrained companies.
