The European Commission’s proposal for a Directive on the award of concession contracts has sparked vigorous public debate and intense opposition. This Directive is controversial because of the nature of the policy it proposes and because the sectors involved are highly sensitive. This Forum examines the weaknesses of the Commission’s proposal and presents an overview of the current issues in water regulation and the provision of water services. The authors analyse the regulation of natural monopolies, water efficiency and upstream competition in the water industry.  相似文献

The current study examines the mediating role of innovation and entrepreneurial competencies in entrepreneurial orientation’s relationship with financial, social, and environmental performance. This research also determines the role of social ties in strengthening the association between innovation and entrepreneurial competencies with social, financial, and environmental performance. Using multi-source and time-lagged studies, the data was collected from 297 small and medium-sized enterprises (SMEs) in Pakistan, and structural equation modeling was used to test direct, indirect, and moderating hypotheses. The findings show that entrepreneurial orientation, entrepreneurial competencies, and innovation positively correlate with all the types of performance under investigation and confirm the mediating role of innovation and entrepreneurial competencies. Additionally, social network ties strengthen innovation—financial performance, and entrepreneurial competencies—social performance relationship. This research proposes significant theoretical and managerial implications by determining the impact of entrepreneurial orientation on SMEs in Pakistan.  相似文献

An initial public offering (IPO) is one of the most critical events in the life of a firm. As the IPO market continues to attract attention from both entrepreneurs and investors, research examining the relationship between the firm's characteristics and its IPO performance is growing. In this paper, we use the upper echelon perspective to empirically examine the relationship between the firm's chief executive officer (CEO) and the firm's time to IPO, a relationship that has so far received little attention. Using data obtained from 237 IPOs in the U.S. software industry, we found that the CEO's prior executive experience, network, and age are significantly related to the new firm's time to IPO. This study extends the understanding of the important role of the CEO in the IPO and provides investors greater insight into those variables that influence the speed with which firms go public.  相似文献

Si considera la classe delle funzioni realiF(x,y) definite inS×S, conSR N , che soddisfano per ognix,yS la condizione di monotoniaF(x,y)+F(y,x)0. Indebolendo la precedente disuguaglianza si introducono classi di funzioni monotone generalizzate e, supponendo soddisfatta una opportuna condizione di omogeneità, si caratterizzano tali funzioni in base alla struttura del segno delle funzioni x, v (t, s) = F(x + tv, x + sv), x S, v R N \{0}. Infine dopo aver definite le funzioni F-differenziabili, si introducono classi di funzioni conversse generalizzate, rispetto ad F, e si studiano i collegamenti tra queste classi e la monotonia generalizzata diF.
Summary We consider the class of real valued functionF(x,y) defined inS×S, withSR N , satisfying x,yS the monotone conditionF(x,y)+F(y,x)0. Weakening the previous inequality we introduce the class of quasi-monotone, pseudo-monotone and strictly pseudo-monotone functions. Under a suitable assumption of homogeneity we characterize the generalized monotone functions studying the sign structure of the functions x, v (t, s) = F(x + tv, x + sv), x S, v R N \{0}.Finally by means of the notion ofF-differentiability we introduce new classes of generalized convex functions (with respect toF) and we study the relationship between these classes and the generalized monotonicity ofF.

This paper builds a unifying framework based on the theory of intertemporal consumption choices that brings together the limited participation‐based explanation of the Consumption Capital Asset Pricing Model's poor empirical performance and the transaction costs‐based explanation of incomplete portfolios. Using the implications of the consumption model and observed household consumption and portfolio choices, we identify the preference parameters of interest and a lower bound for the costs rationalizing non‐participation in financial markets. Using the US Consumer Expenditure Survey and assuming isoelastic preferences, we estimate the coefficient of relative risk aversion at 1.7 and a cost bound of 0.4% of non‐durable consumption. Our estimate of the preference parameter is theoretically plausible and the bound sufficiently small to be likely to be exceeded by the actual total (observable and unobservable) costs of participating in financial markets.

This paper presents empirical evidence that accounting for heterogeneity in financial market participation is important for evaluating the empirical performance of the Consumption-based Capital Asset Pricing Model (C-CAPM). Using the US Consumer Expenditure Survey as a common testing ground, I re-assess three well-known characterizations of the equity premium puzzle (i) the inconsistency of the representative agent's IMRS with Hansen and Jagannathan bounds; (ii) Mehra and Prescott's calibration of a large representative agent's risk aversion; (iii) Hansen and the Singleton's large structural estimates of the preference parameters based on aggregate data. In all three cases, the estimates of risk aversion conditional upon financial market participation are not as far from reasonable values as the corresponding unconditional ones. The differences suggest that part of the equity premium puzzle can be accounted for by the use of a representative agent assumption rather than a more appropriate "representative stockholding agent assumption.  相似文献

Corporate governance issues arising from concentrated ownership structure in emerging economies have received growing attention. Adopting a principal–principal perspective, this paper employs structural equation modeling to evaluate the independent and interdependent effects of internal governance mechanisms in enhancing firms’ value in China. Based on a 3-year dataset covering 304 publicly listed companies over 2003–2005, our findings suggest that ownership concentration has the most significant governance effect and has impacted negatively on firm performance. Furthermore, the governance role of the board of directors and supervisory boards is found to have been hindered by ownership concentration, rendering them unable to improve firm performance at present.  相似文献
