Empirical Patterns of Firm Growth and R&D Investment: a Quality Ladder Model Interpretation.

We present a model of endogenous firm growth with R&D investment and stochastic innovation as the engines of growth. The model for firm growth is a partial equilibrium model drawing on the quality ladder models in the macro growth literature, but also on the literature on patent races and the discrete choice models of product differentiation

Learning from openness : the dynamics of breadth in external innovation linkages

We explore how openness in terms of external linkages generates learning effects, which enable firms to generate more innovation outputs from any given breadth of external linkages. Openness to external knowledge sources, whether through search activity or linkages to external partners in new product development, involves a process of interaction and information processing. Such activities are likely to be subject to a learning process, as firms learn which knowledge sources and collaborative linkages are most useful to their particular needs, and which partnerships are most effective in delivering innovation performance. Using panel data from Irish manufacturing plants, we find evidence of such learning effects: establishments with substantial experience of external collaborations in previous periods derive more innovation output from openness in the current period

Economics Research in Canada: A Long-Run Assessment of Journal Publications

We examine the publications of authors affiliated with an economics research institution in Canada in (i) the Top-10 journals in economics according to journals’ impact factors, and (ii) the Canadian Journal of Economics. We consider all publications in the even years from 1980 to 2000. Canadian economists contributed about 5% of publications in the Top-10 journals and about 55% of publications in the Canadian Journal of Economics over this period. We identify the most active research centres and identify trends in their relative outputs over time. Those research centres successful in publishing in the Top-10 journals are found to also dominate the Canadian Journal of Economics. Additionally, we check the robustness of our findings with respect to journal selection, and we present data on authors’ Ph.D.- origin, thereby indicating output and its concentration in graduate education

An empirical analysis of patents flows and R&D flows around the world

In this article, we empirically investigate the effect of Research and Development (R&D) flows on patent flows around the world. We do this using an unbalanced panel consisting primarily of Organization for Economic Co-operation and Development (OECD) countries that have both patent and R&D expenditure information broken down by domestic and foreign sources. Our analysis shows that even among a fairly homogeneous group of countries, the sources of patents and R&D differ substantially. Using a dynamic panel framework, we find that domestic R&D per capita increases domestic patents per capita only for the European Patent Convention (EPC) countries that already have a decentralized approach to innovation. Foreign R&D per capita increases foreign patents per capita in all countries even though foreign R&D constitutes a very small fraction of total R&D. We find that some of these differences can be attributed to the locations of the patent applications, including those to the European Patent Office (EPO), United States Patent and Trademark Office (USPTO) and triadic patent applications to the EPO, USPTO and Japan Patent Office (JPO) simultaneously

Long-run relationship between R&D investment and environmental sustainability:Evidence from the European Union member countries

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.The researchers, environmental scientists and policymakers around the world are exerting substantial efforts to mitigate the growth of CO2 emissions to save the planet. A number of measures and initiatives, such as, energy efficiency, renewable energy technologies and emission-control are proposed in order to reduce CO2 emissions. This study examines the long-run relationship between R&D investment and environmental sustainability in a panel of 25 European Union (EU) member countries over a period of seventeen years (1998 to 2014). We use robust and reliable econometric methods to capture the interactions between R&D investment on renewable energy consumption and CO2 emissions. The findings confirm that the growth of R&D expenditures promotes renewable energy consumption and plays a significant role in reducing CO2 emissions in the sample countries. Furthermore, the findings suggest that increasing the share of renewable energy consumption in the total energy mix also reduces CO2 emissions. Given these results, we suggest that the EU policymakers provide more financial and regulatory assistance to the R&D activities, specifically in the energy sector, to ensure promoting low carbon economies in this region

Does R&D spur productivity growth in Australia’s broadacre agriculture? A semi-parametric smooth coefficient approach

© 2018 Informa UK Limited, trading as Taylor & Francis Group This article analyses the role of research and development (R & D) in Australia’s broadacre farming by using the semi-parametric smooth coefficient model. While the conventional production function approach only captures the direct effects of R & D, this methodology captures both the direct impact of a change in R & D on output and the indirect impact through changes in efficiency of use of factor inputs in the production process. Moreover, technical inefficiency is introduced in the model allowing it as a function of R & D. Using a unique state-level dataset covering the period 1995–2007, this empirical study finds that once both the direct and indirect effects are taken into consideration, R & D investments significantly increase outputs. The results also show that there are substantial variations in the effects of R & D on output across the state-level average farm through technology parameters as well as through technical inefficiency. Such variations need to be taken into account when designing policies for investing public R & D in agriculture

Does regulation drive international research cooperation? Evidence from the pharmaceutical sector

To what extent is an increased stringency of the Intellectual Property Rights (IPR) system apt to stimulate research cooperation between developed and emerging economies? To address this question, we empirically investigate how international joint research projects in the pharmaceutical sector are affected by the regime of IPR in force in the two countries involved in the collaboration. Looking at the joint signature of both patent documents and scientific articles by researchers located in developed and emerging markets, our investigation indicates two opposite effects: joint publications are fostered by stricter IPR rules, whereas joint patents are discouraged. A recently proposed theory provides a plausible rationale for this apparently contradicting result
