In this paper, we test for the stationarity of European Union budget deficits over the period 1971–2006, using a panel of
thirteen member countries. Our testing strategy addresses two key concerns with regard to unit root panel data testing, namely
(1) the presence of cross-sectional dependence among the countries in the panel and (2) the identification of potential structural
breaks that might have occurred at different points in time. To address these concerns, we employ an AR-based bootstrap approach
that allows us to test the null hypothesis of joint stationarity with endogenously determined structural breaks. In contrast
to the existing literature, we find that the EU countries considered are characterised by fiscal stationarity over the full
sample period irrespective of us allowing for structural breaks. This conclusion also holds when analysing sub-periods based
on before and after the Maastricht treaty. 相似文献

Studies of innovation networking have frequently been concerned with the occurrence of dyadic relationships and with their apparent impact on simple measures of firm-level innovation outputs. This paper takes a more detailed look by analyzing the connection between different types of innovation and forms of networking. Based on the market novelty of innovation outcomes and the extent to which innovation activities require new competences, four types of innovation are identified. It is proposed that these types correlate with various innovation network dimensions, including the volume of networks, the strength and content of ties, and the specificity of ties. Drawing on survey data of 594 innovations realized by Dutch small firms, it is observed that the requirement to access new competences for innovation correlates positively with the number of network partners involved. We also note more subtle connections between types of innovation and networking, including that novel innovation outputs correlate with using network partners as a source of inspiration, whilst new competences associate with networking for knowledge capital. In the latter case, these activities also draw on new and intended ties relatively often, i.e. network partners which are actively sought out for the specific contributions they may make to the innovation process. Finally, innovation which is simultaneously new-to-the market and requires new competences uses strong ties relatively often. Implications for innovation policy and practice are discussed. 相似文献

Few studies have investigated whether parents’, teachers’ and children’s responses to the strengths and difficulties questionnaire (SDQ) have equivalence. In this study, data from 854 matched questionnaires collected in Malaysia were subjected to tau equivalence confirmatory factor analysis, to assess if all three groups responded to the same target (the child) similarly. We first fitted Goodman’s (Journal of Child Psychology and Psychiatry, 38, 581–586, (1997a); Journal of Child Psychology and Psychiatry, 40, 791–801, 1997b) five factor model, but found that this did not fit the model despite attempts to improve and rectify model fit. We thereafter attempted to fit Dickey and Blumberg (Journal of the American Academy of Child Adolescent Psychiatry, 43, 1159–1167, 2004) three factor model, but similarly found a lack of fit. We then undertook an exploratory model with a random half of the data, obtaining a three factor solution, and tested this in a confirmatory tau equivalence model. The Unconstrained Model provided a fit to the data, revealing a similar structure across the three informant groups. As this fit was for the Unconstrained Model, it reveals that groups differ in the value they place on each of the variables but overall that held a similar underlying factor structure. The findings are discussed in relation to the possible cultural issues involved and the use of the SDQ. 相似文献

This paper uses the British Household Panel Survey to present the first estimates of the housework-wage relationship in Britain. Controlling for permanent unobserved heterogeneity, we find that housework has a negative impact on the wages of men and women, both married and single, who work full-time. Among women working part-time, only single women suffer a housework penalty. The housework penalty is uniform across occupations within full-time jobs but some part-time jobs appear to be more compatible with housework than others. We find tentative evidence that the housework penalty is larger when there are children present. 相似文献

Business people often consider spirituality a means of increasing integrity, motivation and job satisfaction. Yet certain spiritualities are superficial and unstable. Religion gives depth and duration to a spirituality, but may also sew divisiveness. A spirituality's ability to develop good moral habits provides a positive test of the "appropriateness" of that spirituality for business. Many successful business executives demonstrate a spirituality that does develop good moral habits. 相似文献

Codes of ethics are being increasingly adopted in organizations worldwide, yet their effects on employee perceptions and behavior have not been thoroughly addressed. This study used a sample of 613 management accountants drawn from the United States to study the relationship between corporate and professional codes of ethics and employee attitudes and behaviors. The presence of corporate codes of ethics was associated with less perceived wrongdoing in organizations, but not with an increased propensity to report observed unethical behavior. Further, organizations that adopted formal codes of ethics exhibited value orientations that went beyond financial performance to include responsibility to the commonweal. In contrast to corporate codes of ethics, professional codes of ethical conduct had no influence on perceived wrongdoing in organization nor these codes affect the propensity to report observed unethical activities. 相似文献

We present a model that separates entrepreneurship from profit-motivated corporate R&D aimed at improving existing production processes. Our model embeds the core idea of the knowledge spillover theory of entrepreneurship in established knowledge-based growth models by enriching their knowledge spillover structure. Introducing knowledge spillovers drives a wedge between the optimal and market allocation of resources between new knowledge creation and commercialization. We show the first best allocation depends exclusively on the relative strength of knowledge spillovers between them and derive propositions to guide policy that can bring the market equilibrium closer to this optimum. 相似文献

This study evaluated the effectiveness of red-light cameras in Dammam, the Kingdom of Saudi Arabia. Two methods were used to assess changes in crash risk at the intersections at which the red-light camera programme had been operating. Geospatial analysis was used to visualize trends in road crash density over the geographical region of Dammam and a pre--post-camera crash analysis was undertaken. The distribution of injury crashes was greater than that of crashes which included property damage, the latter of which was concentrated around central Dammam. The five red-light cameras installed in 2012 were located outside areas of high-crash and injury density, and the total number of crashes reported in the three-month periods after installation was double that before the cameras were installed. This increase in the number of crashes also occurred at the five comparison sites (without red-light cameras), indicating a null effect. The findings from this study are contrary to previous evaluations of speed management programmes associated with red-light cameras. The study highlights the challenges in obtaining data for such research and illustrates that a reliance on overt, fixed camera's to manage speed is unlikely to deliver significant reductions in road trauma. 相似文献
