In this paper we propose a model to analyse the motivation of academic entrepreneurs that comprises six dimensions: personal,
relating to the entrepreneurial opportunity, to scientific knowledge, to the availability of resources, to the incubator organization,
and to the social environment. The model is tested based on information from a survey administered to 152 Spanish academic
entrepreneurs. Our results show that entrepreneurial opportunity is not part of the entrepreneurial motivation, but is of
the utmost importance to academic entrepreneurs. Also, we find the scientific knowledge is the main driver of entrepreneurial
activity in the academia. 相似文献

Interventionist thinkers are now claiming intellectual victory, blaming the free‐market system and its ideology for the current economic collapse. We find this thesis untenable, drawing on the Austrian Business Cycle Theory. Instead, we argue that the roots of our present downturn lie in the monetary system, whose institutional structure is far from any free‐market ideal. Moreover, several government policies have contributed to the problems. 相似文献

This paper analyses the role of health on exits out of and entries into employment using data from the first twelve waves of the British Household Panel Survey (1991–2002). We use discrete-time duration models to estimate the effect of health on the hazard of becoming non-employed and on the hazard of becoming employed. The results show that general health, measured by a variable that captures health limitations and by a constructed latent health index, affects entries into and exits out of employment; the effects being higher for men than for women. The results are robust to different definitions of employment, and to the exclusion of older workers from the analysis. 相似文献

Energy supply and demand, and as a consequence energy prices, are likely to represent one of the biggest challenges of the 21st century. Commodity markets exhibit increased volatility when there is little or no underutilized supply capability to meet natural fluctuations in demand. In the case of energy markets, the large capital requirements and significant lead times associated with energy production and delivery make them more susceptible to the imbalances in supply capability and demand. Energy price volatility has destructive impact on market agents, and this impact is intensified when the prices exhibit asymmetric volatility. This article pursues two aspects of the issue. First we consider general aspects, especially the asymmetric pattern of volatility of daily returns of different types of energy products. Then, we analyze the behaviour of daily returns by using traditional models of volatility that include AGARCH, TGARCH, EGARCH, and ARSV strategies, as well as a threshold asymmetric autoregressive stochastic volatility (TA-ARSV) model that we propose. The energy products considered in this analysis are probably the most relevant energy products for the economic activity of the nations and the economic relations between countries: Crude Oil (OPEC reference basket and London Brent index), Gasoline, Natural Gas, Butane, and Propane. We use spot prices and the time reference ranges from 1986–1993 to 2009 depending on the product. 相似文献

Using the EU‐SILC database, we estimate and compare the Inequality of Opportunity (IO) of 23 European countries in 2005. IO is estimated as the between‐type (ex‐ante) inequality component following the parametric procedure of Ferreira and Gignoux (2011 ), which allows for the inclusion of the large set of circumstances in the database. We also measure the degree of correlation between IO estimates and a set of past and contemporaneous economic factors related to the degree of development, labor market performance, investment in human capital, and social protection spending. 相似文献

We study the corporate governance of firms in environments where possibly heterogeneous shareholders compete for possibly
heterogeneous managers. A firm, formed by a shareholder and a manager, can sign either an incentive contract or a contract
including a Code of Best Practice. A Code allows for better management control, but makes it hard for managers to react quickly
when market conditions change. Codes tend to be adopted in markets with low volatility and in environments where managers
obtain low levels of benefits. The firms with the best projects tend to adopt a Code when managers are not too heterogeneous,
while the best managers tend to be hired through incentive contracts when the projects are similar. Although the matching
between shareholders and managers is often positively assortative, shareholders with the best projects might be willing to
renounce hiring the best managers; instead, signing contracts including Codes with lower-ability managers. 相似文献

In this study the authors analyse the possible effect of firms' economic conditions and financial performance on accounting quality. Bradshaw, et al. (2004), Gelos & WEI (2005) stated that financial reporting quality is fundamental for investors and it affects international capital movements. Following Schipper & Vicent (2003), the authors estimated accounting quality by abnormal accruals and earnings persistence. The authors' contribution consists of investigating a huge number of firms from 17 European countries using unbalanced panel data. The authors found evidence that economic conditions affect accounting quality: big firms and those with high current earnings exhibit better financial information. These results are robust because they do not depend on the accounting quality proxy, even when the authors estimated regression with economical and financial factors alone or together. Financial performance does not seem to affect accounting quality. However, this relation is not linear because in high leveraged firms, the capital structure becomes determinant. 相似文献

- The topic of donations is one of high relevance and has been widely covered in contemporary marketing literature. It is a topic of interest to both theoreticians and practitioners alike, particularly due to its implicit links to fundraising activities and research. The reality of what makes an individual donor ultimately part with his money and give it away to a nonprofit organization is a hot contemporary topic. This study looks into the role of religiosity as a predictor of donations practices. Also volunteerism and compassion, two acts of pro‐social behaviour are analysed as predictors of donations practices. Using data collected from a survey of 612 charity donors in Portugal, the results show unequivocally that religiosity does influence donations practices, and so being a predictor of donations practices. Moreover, pro‐social behaviour is a predictor of donations practices when in the case of volunteerism, but not in the form of compassion.
- The findings are particularly useful for nonprofit organizations that want to attract and retain individual charitable donors and may also help to increase donation regularity, to obtain higher amounts, and donations both to religious and to secular organizations. Finally, it can be stated that the understanding of religiosity sheds light on knowledge about donations practices, and that this study also makes an important contribution to academia, as it is the first study conducted in Portugal that assesses the drivers of donations practices.

The present study shows how the evaluation of sport motivation according to Achievement Goal Theory is different if the criteria
used are predominant goal orientation or motivational profile combination, as well as presenting its relationship with other
variables such as the amount of sport practise or the level of competition and success achieved. Seventy two men and women
participated, all students of Physical Educational and Sport Science, completing the Questionnaire on Motivational Orientation in Sport ((Guivernau and Duda, Revista de Psicología del Deporte, 5, 1994) a Spanish adaptation of the Task and Ego Orientation in Sport Questionnaire, TEOSQ, (Duda, J Sport Exerc Psychol, 11, 1989)). The results showed the existence of different motivational relationships
with variables of the practise of sport, depending on the type of profile used. Finally, the practical implications of these
findings are discussed with respect to the motivational climate generated in the teaching of Physical Education. 相似文献

This paper studies empirically the relationship between the sources of knowledge, innovation and productivity in Knowledge
Intensive Business Services using French micro data and sheds some new light on the production of knowledge and on effects
of innovative output on firm productivity. Both an innovation function and a production function augmented with dummy endogenous
innovation are estimated. Three estimators which control for endogeneity of the dummy innovation are employed: the first is
a maximum likelihood estimator of the equations’ system while the other two are built in the instrumental variables framework.
These estimators give useful complementary information because of the usual efficiency-robustness tradeoff comparing system-equations
and single-equation estimators. We find that innovation is frequent in Knowledge Intensive Business Services and has a strong
and positive effect on productivity. As in manufacturing, the main determinant of innovation is formal knowledge resulting
from R&D or from acquisitions of equipment, patents or licenses. 相似文献
