In the current global corporate climate that surrounds us, firms would do well to encourage the talent and creativity of their employees to achieve success. This is achieved, not by giving priority to individual talent, but by optimizing the collective as a whole and with the firm’s activities based on teamwork and joint effort. Heads of organizations might benefit from creating a favorable context for the birth and growth of collective internal cooperation, which is understood to be the collective ability to create and innovate on the part of the team, the firm or the organization. Having contrasted our hypotheses through research on Spanish firms, we have concluded that job satisfaction and commitment to the team are factors that have a direct and positive effect on Internal Entrepreneurship.   相似文献

We focus on how interpersonal characteristics should influence leader support for gender equity in organizations. Recognizing gender disparities in organizations and the “labyrinth” that women face when they advance in their careers (cf. Eagly & Carli, 2007), we develop a model for how interpersonal characteristics of leaders, both men and women, influence power construal and thus their use of empowerment, mentoring, and performance feedback, ultimately affecting career opportunities for women in organizations. The model proposes that leaders who are high on communal goal orientation, a prosocial characteristic, are more likely to construe power through a responsibility lens and behave in ways that ultimately support gender equity in organizations. In contrast, leaders with an exchange goal orientation are more likely to construe power through a freedom lens and behave in ways that are self-serving. Prestige motivation will increase the extent to which leaders, especially those who are communally oriented, share power. Dominance motivation will increase the extent to which leaders, especially those who are exchange oriented, act in self-interest and retain power, ultimately imposing barriers to women's career advancement. Organizations can potentially increase leader power sharing by encouraging and reinforcing leaders' prosocial characteristics of communal orientation and prestige motivation. Implications for research and practice are discussed.  相似文献

This paper examines the relationship between knowledge spillovers from universities and new business location in high-technology sectors. We focus on the contribution to new business formation through spillovers stemming from three main university outputs: knowledge-based graduates, research activities, and technological knowledge. We construct a new dataset with information on 604 companies and 63 universities in Spain and group the data across 36 geographical areas from 2001 to 2004 (144 observations). After controlling for several traditional cost factors and agglomeration characteristics, we find that university spillovers are relevant in explaining the location of new businesses in high-technology sectors in Spain. Further, our analysis draws attention to the relevance of graduates as the main source of spillovers, while research activities and university technology do not have significant effects.  相似文献

Current accounts have diverged substantially among euro area countries since the creation of the euro. This divergence has raised concerns about the sustainability of some member countries’ external indebtedness. This paper uses an intertemporal model of the current account to analyze the fluctuations in current account balances experienced by euro area countries over the last three decades and to disentangle its determinants. We find that the model is not rejected for six of the ten euro area countries examined (Belgium, France, Italy, Netherlands, Portugal and Spain), although it tends to underestimate their current account volatility. For these countries, we derive the expectations about future income and relative prices, which, according to the model, underlie their current account balances. Expectations about future growth increased in all Southern European countries at the creation of the euro, but they diverged considerably by 2005. While in Portugal these expectations were below its historical mean by then, in Spain they were at an historical high.  相似文献

This article presents a new semi‐nonparametric (SNP) density function, named Positive Edgeworth‐Sargan (PES). We show that this distribution belongs to the family of (positive) Gram‐Charlier (GC) densities and thus it preserves all the good properties of this type of SNP distributions but with a much simpler structure. The in‐ and out‐of‐sample performance of the PES is compared with symmetric and skewed GC distributions and other widely used densities in economics and finance. The results confirm the PES as a good alternative to approximate financial returns distribution, specially when skewness is not severe.  相似文献

In the last few years several research studies have challenged the traditional weak-form efficiency tests of the stock market. These studies suggested an alternative to the random walk model, containing temporary and permanent components. If stocks follow such a model then the traditional tests, using returns computed for short intervals would be unable to detect them. To investigate the evidence for such models in the Portuguese stock market ten stock indexes were created. This is a pioneer study of the Portuguese stock market, and uses nominal, real and excess returns, computed for longer horizons. Three methodologies were used: variance ratios, ordinary least squares regressions and weighted least squares regressions. The statistical significance of the results was studied using traditional parametric tests as well as non-parametric tests. The evidence is mixed, as the presence of tendencies towards mean aversion and mean reversion were detected. Results also show that the evidence is very sensitive to the methodology used and the signifcance tests performed. These results, however, do not necessarily reject the weak-form market efficiency hypothesis.  相似文献
