The Effect of Market Entry on Innovation: Evidence from UK University Incubators

This paper investigates the effect of market entry of new firms on incumbent firms' innovative activity measured as patent applications. The basic assumption is that the effect of entry varies by geographical distance between entrants and incumbents due to the presence of localized unobserved spillovers. In order to avoid endogeneity problems commonly associated with the timing of entry and entrants' location choice, I analyze entry induced by the establishment of university business incubators, which are usefully exogenous in time and space. The results show that entry has a statistically and economically significantly positive strategic effect on incumbent patenting which is attenuated by the geographical distance between entrant and incumbent.Patents, market entry, incubators, spillover

Does the Rotten Child Spoil His Companion? Spatial Peer Effects Among Children in Rural India

This paper identifies the effect of neighborhood peer groups on childhood skill acquisition using observational data. We incorporate spatial peer interaction, defined as a child’s nearest geographical neighbors, into a production function of child cognitive development in Andhra Pradesh, India. Our peer group construction takes the form of directed networks, whose structure allows us to identify peer effects and enables us to disentangle endogenous effects from contextual effects. We exploit variation over time to avoid confounding correlated with social effects. Our results suggest that spatial peer and neighborhood effects are strongly positively associated with a child’s cognitive skill formation. These peer effects hold even when we consider an alternative IV-based identification strategy and different variations to network size. Further, we find that the presence of peer groups helps provide insurance against the negative impact of idiosyncratic shocks to child learning.Children, peer effects, cognitive skills, India

Patents, Entrepreneurship and Performance

This paper provides an overview of a new database that uses intellectual property data to track the innovative activity of firms in the UK. The paper looks at the extent and nature of patenting activity, focusing on micro firms and SMEs. Over the period 2000 to 2007, SME patenting has increased whereas large firm patenting has fallen and micro firm patenting has been roughly con- stant. Most micro and SMEs patent while relatively young (aged ten or less) and this tendency is becoming more pronounced over time. The paper provides a descriptive analysis on micro firms and SMEs that become high growth firms (defined as having greater than 20 percent growth per annum). Overall, 28.0 percent of young micro and SMEs achieve high growth (over 2002 to 2007). In comparison, 29.4 percent of young micro or SMEs that patent achieve high growth. This difference is much greater for firms in the high-tech industries. Moreover, the analysis shows that due to the skewed nature of the firm-level growth distribution, standard conditional mean estimators may fail to uncover important differences in the association between patenting and firm growth across the conditional growth distribution.Firm growth, patents

Business R&D expenditure and capital in Europe

This study presents new estimates of business R&D capital stocks for 22 countries at the aggregate and industry levels. At 9 percent of GDP, the EU business R&D capital stock falls short of its US and Japanese counterparts. Within the EU, R&D capital stocks are much lower in the southern and the new member states, reflecting large and persistent disparities in R&D expenditure. There was hardly any convergence over the past decade. The R&D capital stock is concentrated on three technologyintensive manufacturing industries and is positively correlated with growth in total factor productivity across countries and industries. Finally, the ratios between the stocks of R&D capital and tangible capital suggest marked differences in how R&D and tangible capital are combined in production.R&D capital stock; R&D expenditure; tangible capital stock; R&D intensity; high-tech manufacturing

Export Subsidies in a Heterogeneous Firms Framework: Evidence from Colombia

We evaluate the impact of firm-specific export subsidies on exports in Colombia. Using a twostage selection correction procedure, we obtain firm-specific predicted subsidy amounts that can be explained by the characteristics that determine the firms’ eligibility for government support and its amount. Drawing on the accounts of the discretionary allocation of subsidies in developing countries, we regard the discrepancy between the predicted and the observed subsidy amounts as a proxy for a firm’s ties to government officials. Controlling for observable and unobservable firm characteristics and persistence in exports, we find that although, in general, subsidies exhibit a positive impact on export volumes, this impact is diminishing in subsidy size and in the degree of a firm’s connectedness.Export promotion; export subsidies

Does the Rotten Child Spoil His Companion? Spatial Peer Effects Among Children in Rural India

This paper identifies the effect of neighborhood peer groups on childhood skill acquisition using observational data. We incorporate spatial peer interaction, defined as a child's nearest geographical neighbors, into a production function of child cognitive development in Andhra Pradesh, India. Our peer group definition takes the form of networks, whose structure allows us to separately identify endogenous peer effects and contextual effects. We exploit variation over time to avoid confounding correlated with social effects. Our results suggest that spatial peer and neighborhood effects are strongly positively associated with a child's cognitive skill formation. Further, we find that the presence of peer groups helps provide insurance against the negative impact of idiosyncratic shocks to child learning. We show that peer effects are robust to different specifications of peer interactions and investigate the sensitivity of our estimates to potential mis-specification of the network structure using Monte Carlo experiments. --Children,peer effects,cognitive skills,India

Innovation and diffusion of clean/green technology: Can patent commons help?

This paper explores the characteristics of 238 patents on 94 “inventions” contributed by major multinational innovators to the “Eco-Patent Commons”, which provides royalty-free access to third parties to patented climate change related innovations. By comparing the pledged patents to other patents in the same technologies or held by the same multinationals, we investigate the motives of the contributing firms as well as the potential for such commons to encourage innovation and diffusion of climate change related technologies. This study, therefore, indirectly provides evidence on the role of patents in the development and diffusion of green technologies. More generally, the paper sheds light on the performance of hybrid forms of knowledge management that combine open innovation and patenting.patent commons, green technology, eco-aptents, diffusion, climate change

The role of patent protection in (clean/green) technology transfer.

Global climate change mitigation will require the development and diffusion of a large number and variety of new technologies. How will patent protection affect this process? In this paper we first review the evidence on the role of patents for innovation and international technology transfer in general. The literature suggests that patent protection in a host country encourages technology transfer to that country but that its impact on innovation and development is much more ambiguous. We then discuss the implications of these findings and other technology-specific evidence for the diffusion of climate change-related technologies. We conclude that the “double externality” problem, that is the presence of both environmental and knowledge externalities, implies that IP may not be the ideal and cannot be the only policy instrument to encourage innovation in this area and that the range and variety of green technologies as well as the need for local adaptation of technologies means that patent protection may be neither available nor useful in some settings.Climate change; intellectual property; innovation; technology transfer

Trade Mark Cluttering: An Exploratory Report Commissioned by UKIPO

This report explores the problem of “cluttering” of trade mark registers. The report consists of two parts: the first presents a conceptual discussion of “cluttering” of trade mark registers. The second part provides an exploratory empirical analysis of trade mark applications at the UK Intellectual Property Office (UKIPO) and the European trade mark office (OHIM). This part contains results of a descriptive and an econometric analysis. According to our definition, cluttering arises where firms hold trade marks that are overly broad or unused raising search costs for later applicants. The report distinguishes between three mechanisms that can lead to cluttering. It also considers a series of mechanisms that work against cluttering. This discussion is based on a review of the previous literature. The tentative empirical evidence provided in the second part of the report suggests that trade marks are more frequently registered in several classes at the same time and also that firms in pharmaceuticals increasingly resort to multiple simultaneous applications to ensure that they will register at least one trade mark. There is also some evidence that firms seek to avoid mechanisms such as relative grounds examination which can prevent cluttering. Finally, we report direct survey-based evidence that applicants perceive cluttering to be a problem in specific fields and countries. However, our exploratory analysis does not provide strong evidence that cluttering has already become a systemic problem for the trade mark systems that is comparable to the effect of patent thickets for patent systems

Innovation and the survival of new firms across British regions

This paper analyses the survival of the complete cohort of more than 162,000 limited companies incorporated in Britain in 2001 over the subsequent five-year period. For this purpose, we estimate firms' hazards of failure and survival functions using nonparametric and semi-parametric techniques. The paper focuses on two important policy-related issues.The first is to what extent survival rates vary across regions in Britain. A second, and related, policy issue concerns innovation. The data available allows us to look at the intellectual property (IP) activity of all British firms, including that of the 162,000 new firms in 2001. The results indicate substantial differences in survival rates across regions, and also that IP activity is associated with a higher probability of survival. These differences across regions, and the importance of IP activity, remain when we condition on a large range of regional, industry and firm-level characteristics shifting firms' hazards of failure
