Does Inertia Pay Off? Empirical assessment of an evolutionary-ecological model of human capital decisions at firm level

This paper empirically assesses the validity of a model which combines organisational ecology and evolutionary theory to analyse human capital accumulation decisions at firm level. The main argument of the model is that factors underlying the process of plants’ reproduction, especially the process of fission, must be isolated and related to the economic motivations of employers to hire top educated and highly skilled people. Inert behaviour in human capital accumulation decisions stands here as a rational outcome. Logistic estimates, based on the whole population of plants of the Portuguese textiles, provide statistical evidence corroborating the fission hypothesis. This evidence constitutes a critical examination of the mainstream economics concerning the demand side of human capital.Human capital; population ecology theory; evolutionary theory; Inertia; Fission; textiles; Portugal

What Type of Firm Forges Closer Innovation Linkages with Portuguese Universities?

Using large-scale survey data for firms located in Portugal, we analyze which firm characteristics are conducive to establishing contacts with universities. Although almost half of the firms surveyed stated they had established some contacts with universities in the period 2001-2003, only a few (22%) consider universities an important source of knowledge and information for their innovation activities. Our analysis indicates that the firms’ propensity to draw on each of the Portuguese universities is explained by the characteristics of the different firms and their regional and industrial patterns. An unambiguous and statistically robust finding is that proximity matters highly in firmsuniversities linkages – our estimations reveal that firms are more likely to contacts universities located nearby.

On the Link between Human Capital and Firm Performance. A Theoretical and Empirical Survey

The present paper provides a review of the literature focusing the relationship between human capital and performance essentially at firm level. The exposition is approached in three different but interrelated perspectives: economic, technological and survival. The exercise of reviewing existing literature permitted to uncover four major neglected issues: 1) the analysis of human capital – skills relationship; 2) the determinants of demands for human capital and how those demands change; interrelated with the second, 3) the influence of social and institutional context on the accumulation of human capital; and 4) the link between human capital and firms capacity of survival at both theoretical and empirical grounds.Human Capital, Skills, Economic Performance, Technological Performance, Survival

Attitudes of Higher Education students to new venture creation: a preliminary approach to the Portuguese case

Institutions of higher education have an important role in the generation of high tech ‘entrepreneurial capacity’. Being entrepreneurship in Portugal an emergent phenomenon there is an urgent need to better understand and develop this area not only by analysing the ‘supply side’ (i.e., the courses taught in this field) but also the ‘demand side’, that is, the attitudes of students, future potential entrepreneurs, to new venture creation. Based on 4413 responses of students enrolled in Portuguese higher education institutions, gathered in June-July 2008, we found, using a multivariate model, that students who had already created a firm although, on average, possess larger entrepreneurial experience and knowledge, they do not reveal high risk propensity or creativity. Those students that have taken some steps to create new businesses and, to a larger extent, those foreseeing their future career as owning their business have higher risk and creative profiles. Students who live in an environment which ‘breads’ entrepreneurship have stronger desire to become entrepreneurs. This supports the contention that entrepreneurship is a learned process and that school, teachers, and other institutions and individuals may encourage entrepreneurial behaviours. ‘Role models’ seem indeed to constitute a key factor fostering entrepreneurship among Portuguese higher education students – in the Portuguese case, the entrepreneur and entrepreneurial company references are, respectively, Belmiro de Azevedo and Sonae. Although in a descriptive analysis students enrolled in non-university (e.g., polytechnics) and private higher education institutions reveal higher effective and potential entrepreneurial propensities, when we (simultaneously) control for a vast number of factors which are likely to affect entrepreneurship propensity, such differences cease to be statistically relevant. Students’ personality (risk, creativity) and demographic traits (gender and age), competencies and familiarity with entrepreneurship (entrepreneurial experience, knowledge, awareness, interest), and contextual factors (professional experience, role models) are important determinants of entrepreneurial propensity, whereas the type of higher education institutions (public vs private, non-university vs university), and, to some extent, the degree (postgraduate vs undergraduate), and the scientific area, fail to emerge as key determinants.students; entrepreneurship; attitudes

Determinants of the international influence of a R&D organisation: a bibliometric approach

Traditionally, studies on the influence and impact of knowledge-producing organisations have been addressed by means of strict economic analysis, stressing their economic impact to a local, regional or national extent. In the present study, an alternative methodology is put forward in order to evaluate the international scientific impact and influence of a knowledge-producing and -diffusing institution. We introduce a new methodology, based on scientometric and bibliometric tools, which complement traditional assessments by considering the influence of a R&D institution when looking at the scientific production undertaken and the recognition of its relevance by its international peer community. Focusing on the most prolific scientific areas of INESC Porto, and resorting to published scientific work recorded in the Science Citation Index (SCI), we show that INESC Porto has enlarged its international scientific network. The logit estimations demonstrate that the wide geographical influence of INESC Porto scientific research is a result not of its international positioning in terms of co-authorships, but rather a result of the quality of its scientific output.Impact and influence assessment methods; R&D Institutions; Bibliometrics, Scientometrics; knowledge network; INESC Porto

Conceptualizing clusters through the lens of networks: a critical synthesis

Clusters, as spatial concentrations of economic activity, constitute an important form of coordination with significant repercussions in the configuration of firm and territorial strategies. They are recognized, both by academics and policymakers, as a territorial pattern of economy yielding critical issues in terms of competitive advantage, innovation, and economic growth. Despite that, a rigorous and clear-cut definition of cluster is still far from being reached. In the present paper, resorting to a critical synthesis of the literature on networks and clusters, we propose a unified, encompassing, and less blurred definition of cluster.Clusters, Networks, Concepts

The importance of Intermediaries organizations in international R&D cooperation: an empirical multivariate study across Europe

Despite the large number of publications related to business cooperation in R&D and the wide perception of the importance of intermediary institutions in the R&D cooperation process, empirical studies on its role are scarce, scattered and fragmented. Moreover, the academic work developed in this area is basically of a theoretical nature, whereas the international perspective of R&D cooperation is seldom approached. Departing from a unique database that includes 473 R&D cooperation projects developed within the 6th Framework Programme, involving firms and intermediaries from all European Union countries, this paper gauges the determinants of the importance attached to Intermediaries, through a direct survey to the organizations involved. Based on an estimation of the multivariate model, this study demonstrates that the importance given to Intermediaries depends more on project features than on the characteristics of the participating organizations. In particular, the nationality of participating organizations and the promoter emerged with a strong explanatory power: ceteris paribus, projects with at least one participant from the United Kingdom tend to assign greater importance to intermediaries in international R&D cooperation. Unambiguously, results evidence that the innovating capacity of an organization emerges (both positively and significantly) associated with a greater importance attached to Intermediaries.R&D Cooperation; Intermediaries; International projects; Europe

One size does not fit all… An economic development perspective on the asymmetric impact of Patents on R&D

Innovation is the building block of competitive advantages and thus economic policies are increasingly focused on creating stimulus to increase a country’s innovative performance and growth potential, namely through knowledge accumulation in general and R&D in particular. In this context, current policy trend seems to support the strengthening of Intellectual Property Rights (IPR), in particular, patent protection, with the argument that positive effects will emerge and would be extensive to all countries regardless their level of development. In this paper we question this “one size fits all” policy and assess how patent thicket affects knowledge productive investment taking into account countries’ development levels. Based on a panel of 95 countries over a ten-year period (1997-2006), our results show that patents have asymmetric impacts across countries development stages, evidencing pervious effects on technological leaders and positive ones on some laggards. Such evidence sustains that innovation policies be adjusted to countries development stages.growth models; R&D; patents; economic development

Does Patenting negatively impact on R&D investment?An international panel data assessment

Although the conventional R&D-patents relationship is a long stand and relatively undisputed issue within the innovation literature, the reverse causality, in particular, the potential for a negative impact of patents over R&D has only recently received wide attention boosting interesting (mainly) theoretical debates. The macroeconomic perspective on this issue, however, remains largely unexplored. In fact, no evidence exists that ruled out the possibility of asymmetric effects of patents on R&D in accordance to the level of GDP in general, and to ‘convergence clubs’ in particular. Using panel data estimation methods on a sample of 88 countries, over an eight-year period (1996-2003), and controlling for clubs of convergence to account for differences on countries’ stages of economic development, we found mix support to the negativity of patent on R&D investment. The accumulated patents positively impact on R&D intensity for the set of less developed countries whereas no statistically significant effect emerges in the case of higher developed converge clubs; restricting the highest developed convergence club down to countries with a R&D intensity above 3%, the negativity reverse causality arises, corroborating the asymmetric impact of patents on R&D investment. We further demonstrate that albeit causality appears to be stronger in the most intuitive appealing traditional direction, evidence supports the theoretical conveyed double causality between R&D and Patent.Patents; R&D; panel data; convergence clubs

Assessing the influence of R&D institutions by mapping international scientific networks: the case of INESC Porto

Although scientometric and bibliometric studies embrace a much wider perspective of the linkages/networks of R&D institutions than standard economic studies, to the best of our knowledge, these studies have not yet made use of scientometric tools to analyse the influence and impact of R&D institutions. Moreover, the international perspective has so far been neglected both in standard and bibliometric studies. Based on networks of 1239 foreign co-authorships and 13035 foreign citation linkages, we demonstrate that INESC Porto international influence has considerably expanded since 2003, a year that coincided with the implementation of an internal policy of granting monetary prizes to publications in scientific international journals. In terms of co-authorship, the network of INESC Porto more than duplicated (13 countries in the initial period to 27 in 2004-07). In terms of citations, INESC Porto’s network encompassed almost 40 countries during the whole period (1996-2007). Its more prolific units (optoelectronics, energy and multimedia) presented a rather distinct pattern both in terms of size and evolution of the corresponding network boundaries. The network size of foreign co-authorships was not much different between the three units by the beginning of the 2000s (around 10 countries) but it evolved quite distinctly. The most remarkable pattern was registered by the multimedia (UTM) unit, whose network size rose exponentially to 21 countries in 2004-07. This contrasted with the decline (down to 8 countries) of the energy (USE) unit. The citation network of the optoelectronic unit (UOSE) was by far the largest, until 2003, involving 34 distinct countries, which contrasted with the size of USE (12 countries) and UTM (1 country). But again, after 2003, the size of the citation network of USE and UTM converged spectacularly to that of UOSE’s, reaching in the last period 21 and 16, respectively. The influence of INESC Porto reaches all five continents, especially when we consider citation networks. Indeed, excluding the citations from authors affiliated in Portuguese institutions, those that most cite INESC Porto’s (and UOSE’s) works are affiliated in institutions located in China, the UK and the US. The scientific works produced by USE influences mostly authors affiliated in institutions located in India, China and Spain, whereas for UTM the corresponding countries are the US, Germany and Italy. We infer from the evidence analysed that not only did the boundaries of INESC Porto’s scientific network substantially enlarge in the period of analysis (1996-2007) but its ‘quality’ also evidenced a positive evolution, with authors affiliated in institutions located in the scientific frontier countries citing works of INESC Porto (and its units).
