Why has a biotechnology industry developed much faster in some countries than in others? Studies indicate that public funding for research is not sufficient for the establishment of a strong biotech industry. What should countries and regions do then, in order to become globally competitive in the area? In this paper I concentrate on the upstream section of biotech growth - the creation of new biotechnology companies - and take a closer look at the case of Portugal, a country where the industry has long been at an embryonic stage. It becomes apparent from the analysis that generalist, top-down measures to stimulate general technological development may not be appropriate to foster a sector composed of many unique characteristics. Evidence from several countries suggests that there is a group of specific factors which all have to be in place simultaneously to allow the emergence of a biotech industry. A careful analysis of the Portuguese example - when set against the background of European and Global biotech - may help regions such as southeast Asia and southern Europe define their paths to bio-competitiveness. 相似文献

The input–output framework has evolved dramatically since its initial formulation. New analytical techniques and extensions have allowed a more comprehensive assessment of the economy and expanded its applicability. Nonetheless, the core of the framework has remained unchanged: an annually compiled input–output table, which conveys monetary flows between sectors in a region in a particular year. Hence, the technical coefficients derived from it are ‘average’ input compositions, neglecting fluctuations in production capacity, seasonality and temporal shocks within that period. This paper develops a consistent methodology to disaggregate the annual input–output table in its time dimension in order to estimate intra-year input–output matrices with distinct technical structures for a particular year. The main advantages in relation to the annual model are to allow seasonal effects to be studied within the input–output framework, to better understand the process of coefficient change and to offer a more comprehensive dynamic view of production. 相似文献

This article seeks to determine whether the innovative capabilities of knowledge-intensive business services (KIBS) do actually differ from other industries through comparing the innovation capacities and financial performance of KIBS with firms operating in other sectors (non-KIBS). Based upon a 1000-firm sample, the results of our estimated econometric model demonstrate that non-KIBS firms are in possession of significantly greater innovation capacities than KIBS firms. These differences were observed across factors such as organisational process innovation, the launch of already existing products in new markets, branding and new product designs. Nevertheless, as regards the actual importance attributed to product/service innovation, KIBS firms place a greater comparative importance on innovation in comparison with their non-KIBS peers. In addition, the empirical evidences display a significantly different range of effects of innovation capacities on financial performance and concludes that non-KIBS firms turn in better comparative performances than specialist KIBS firms. 相似文献

Satisfaction of customers' needs is particularly dependent upon the customer orientation of frontline employees. Understanding the drivers of such orientation is, therefore, a key issue in current research. Research relating perceptions of organisational values with the customer orientation of employees is rather sparse. This topic is approached by investigating the role of selected dimensions of psychological climate in promoting the customer orientation of frontline service employees. A structural equations model is developed and empirically tested, indicating that perceptions of customer, ethical, and innovation climates exert an indirect effect on the adoption of customer-oriented behaviours by frontline employees. 相似文献

Two conflicting predictions have emerged regarding the effect of low–cost information on price. The first states that all Internet retailers will charge the same low price for mass produced goods. The second states that Internet retailers will differentiate to avoid intense price competition. Using data collected in April 1999 on the prices of 107 books in thirteen online and two physical bookstores, we find similar average prices online and in physical stores and substantial price dispersion online. Analysis of product differentiation yields no clear results. The substantial premium charged by Amazon provides indirect evidence of product differentiation. 相似文献

Under contingent fees, the attorney gets a share of the judgment; under conditional fees, the lawyer gets an upscale premium if the case is won which is, however, unrelated to the adjudicated amount. We compare conditional and contingent fees in a principal–agent framework where the lawyer chooses unobservable effort after she has observed the amount at stake. Contingent fees provide better incentives than conditional fees independently of whether upfront payments are restricted to be non‐negative or not. Under contingent fees, the attorney uses her information about what is at stake more efficiently. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

This study examines the features and determinants of intra-industry trade (IIT), horizontal IIT (HIIT) and vertical IIT (VIIT)
between Portugal and the European Union in the period 1996–2002, using a static and a dynamic panel data analysis. The findings
indicate that Portuguese VIIT increased significantly during the period in accordance with the values expected for a developed
country. The regression results show that there is evidence supporting the explanation of VIIT by Heckscher–Ohlin’s (HO) theory
and that Portugal has comparative advantages in low-quality differentiated products. The findings support the theory that,
in general, there is no positive statistical association between HIIT and HO variables. The central theme of this paper is
to show that it may be preferable to use the GMM approach in empirical studies of IIT rather than pooled OLS, fixed effects
or random effects estimators. The results also suggest that the GMM system estimator obtains more reasonable parameter estimates
than the first-differenced GMM estimator.

Although public space is supposed to be democratic and accessible to all, in reality, such access is inegalitarian and exclusionary. The research aims, therefore, to understand how public space that reflects the imposition of interests of dominant ideologies affects the consumption practices of nondominant ideologies. The qualitative research data were collected in the context of urban cycling through in-depth interviews and observation and are analyzed using a hermeneutical approach. The research explains that, in order to deal with the limits of public space use, these consumers use tactics involving (1) disputes for space, (2) disorganized occupation, and (3) transgressive practices; moreover, there is an overlapping relationship between the agency of consumers and public space. 相似文献

Does sentiment impact the sovereign debt markets? This article investigates whether lagged domestic and Euro area irrational sentiment (optimism or pessimism unwarranted by fundamentals) predicts future sovereign bond spreads, in Portugal, between January 2000 and December 2013. We find that domestic and Euro area sentiment negatively forecasts total return spreads and that this effect is stronger during the bailout period. Also, we find that the business sentiment is even most noticed. Therefore, Portuguese sovereign debt market is prone to the influence of investors’ sentiment. 相似文献

This study aims to review what we do (and do not) know about technology entrepreneurship (TE) research to date. Based on a categorized bibliometric analysis resulting from a systematic review of 135 scientific articles published in refereed journals over the past 27 years (1986–2013), we identify the core domains of TE, its intellectual structure, the scientific journals with a major impact in this field of research, and the affiliation and collaboration networks within it. Specifically, through a detailed analysis of article co-citations within the TE area, this study provides co-citation networks of authors, journals, and their respective clusters, revealing their rankings in terms of contributions to the TE literature. This comprehensive analysis can be used to enhance our understanding of TE and support further research in this field. 相似文献
