We intend to further the research related to the factors that determine successful entrepreneurial endeavours by academic researchers, and thus put forth an exploratory model of Knowledge-Based Entrepreneurship (KBE). Given the lack of extant adequate indicators, a new scale was developed based on the most frequently cited constructs in the literature. A sample of 1,401 researchers from Portuguese universities was administered a questionnaire and the data collected permitted a validation with regards to the psychometric properties of the questionnaire, to see its applicability to the study. The findings suggest that the absence of a patenting history or start-up portfolio act as significant barriers to academic entrepreneurship. However, when the institutional strategy is to increase patenting and spin-off activities, the university should begin investing in creating a networking environment capable of reinforcing the researchers’ Social Capital. Observing the example of successful entrepreneurs motivates other researchers to consider the possibility of developing their own ventures. The Structural Equations Modelling (SEM) approach allowed for us to identify and measure the non-linear relationships that shape the core of KBE and influence the attainment of measurable outcomes aimed at encouraging entrepreneurship. A relatively high share of the variance of the dependent variables is explained by the model, ensuring their representativeness and contributing to the state-of-art of the knowledge in this research field. 相似文献

This article analyses the impact that entrepreneurial activity has, from the economic point of view, on a regional economy (Andalusia), based on a Social Accounting Matrix linear model. Moreover, to measure entrepreneurship at regional level, it is defined what can be considered an entrepreneurial initiative company from a quantitative point of view. The results obtained, in terms of Production, GDP and job creation, show how entrepreneurship, in the case of Andalusia, contributes to the sustainability of the economy, its growth and, above all, the reduction of unemployment in the short term. 相似文献

Cognition,Social Impulse,and the Principle of Adaptation: Insights into the Peirce-Veblen Connection
Manuel Ramon Souza Luz 《Journal of economic issues》2019,53(2):349-354
This article seeks to offer insights into the connections between Charles S. Peirce and Thorstein B. Veblen regarding their understanding of the logic of scientific thought and cognition. In this sense, this work explores how both Veblen and Peirce dismissed the Cartesian notion of unmediated cognition and how they sought to depict cognition as a process. Furthermore, this article presents Peirce’s concept of “social impulse” and Veblen’s “principle of adaptation” as complementary perspectives on science and cognition that have strong evolutionary content. 相似文献

The aim of this paper is twofold. Firstly, we introduce a novel semiparametric technique called Genetic Programming to estimate and explain the willingness to pay to maintain environmental conditions of a specific natural park in Spain. To the authors’ knowledge, this is the first time in which Genetic Programming is employed in contingent valuation. Secondly, we investigate the existence of bias due to the functional rigidity of the traditional parametric techniques commonly employed in a contingent valuation problem. We applied standard parametric methods (logit and probit) and compared with results obtained using semiparametric methods (a proportional hazard model and a genetic program). The parametric and semiparametric methods give similar results in terms of the variables finally chosen in the model. Therefore, the results confirm the internal validity of our contingent valuation exercise. 相似文献

This study examines the relationship of motivation to transfer skills and knowledge learned in a computer-based training programme with five groups of variables: individual or general attitudes, situational specific attitudes, reactions, learning, and work environment factors. Hierarchical regression analysis produced a model which explained 60.5% of the variance in motivation to transfer. Individual attitudes and environmental variables explained most of the variance in motivation. A number of mediated relationships were suggested. 相似文献

In this study, we empirically analyze the determinants of heterogeneity in rating assessments across different segments of
the European loan market. We conduct a benchmarking analysis using rating information on European corporate obligors from
nine major Austrian banks that have a large share of foreign lending, particularly in the Central and Eastern European region.
We provide evidence that, generally, overall heterogeneity among rating outcomes for foreign markets is higher than for domestic
markets. Furthermore, we show that heterogeneity increases in transition economies and those markets where Austrian bank involvement
is relatively low. Our evidence supports the hypothesis that heterogeneity in the assessment of credit risk is determined
not only by the objective quality of information, which is deemed to be lower in transition economies, but also by the subjective
access to information about obligors measured by the level of domestic bank involvement in the respective foreign market.
Furthermore, we quantify potential effects on regulatory capital requirements. 相似文献

While sustainable development is recognized as an essential requirement for achieving economic goals without degrading the environment, major problems arise in defining methods for formulating and implementing sustainable strategic actions at the macro‐level, including islands. Bearing in mind this limitation, this research paper will attempt to present a strategic planning methodology for drawing up strategic issues for tourism development from the point of view of sustainability, which is particularly appropriate to islands. The authors first review existing literature on sustainable development with a view to defining a conceptual approach to sustainability and identifying particular areas for sustainable tourism development in the island context. A methodology for formulating strategic issues for sustainable tourism development in Gran Canaria is then drawn up. Sociocultural aspects, the environment and the economy, with particular emphasis on tourism, are examined in order to identify major strategic issues for sustainable development in Gran Canaria.

Prices for emission allowances in Europe’s Emissions Trading System (ETS) have remained low for many years. This has given rise to controversies on whether there is a need for a fundamental reform of the ETS. Potential reform proposals include the introduction of a price fl oor for certifi cates and a market stability reserve, which is a rule-based mechanism for steering the market volume of allowances and is the preferred approach of the European Commission. In this article, we instead recommend retaining the ETS and suggest correcting past mistakes by a single intervention. 相似文献

The main objective of this paper is to estimate the economic capital for covering the external fraud risk within a financial institution. This is a kind of operational risk which is due to acts of a type intended to defraud, misappropriate property or circumvent the law, by a third party. From the methodological point of view, we apply the Loss Distribution Approach (LDA), based on the Internal Operational Loss Database (IOLD) provided by a Spanish Saving Bank. More specifically, we asses the potential impact of the severity distribution on the Capital at Risk (CAR). In absence of normality, we try to adjust the Lognormal, Weibull and Exponential functions when modelling the severity of losses. As a result, we find a high divergence in terms of capital charge depending on the statistical model selected. In consequence, in order to obtain a realistic model, we highlight the relevance of the goodness of fit between the empirical and the theoretical distribution. 相似文献
