This paper analyses the evolution of the welfare states in themajority of OECD countries during the pre-globalisation (194680)and globalisation (19802000) periods. Our purpose isto find out whether globalisation has produced a convergencetowards a smaller welfare state, funded increasingly by non-mobilefactors such as labour, property and consumption rather thanby mobile factors such as capital. The data presented here challengethe claims about such a convergence, showing that social publicexpenditures and public employment have continued to expandduring the globalisation period in most OECD countries. We alsoshow that the welfare states remain rooted in the politicaltraditions that have governed them. 相似文献

We propose a two-stage procedure to estimate conditional beta pricing models that allows for flexibility in the dynamics of asset betas and market prices of risk (MPR). First, conditional betas are estimated nonparametrically for each asset and period using the time-series of previous data. Then, time-varying MPR are estimated from the cross-section of returns and betas. We prove the consistency and asymptotic normality of the estimators. We also perform Monte Carlo simulations for the conditional version of the three-factor model of Fama and French (1993) and show that nonparametrically estimated betas outperform rolling betas under different specifications of beta dynamics. Using return data on the 25 size and book-to-market sorted portfolios, we find that the nonparametric procedure produces a better fit of the three-factor model to the data, less biased estimates of MPR and lower pricing errors than the Fama–MacBeth procedure with betas estimated under several alternative parametric specifications. 相似文献

Tourism image, evaluation variables and after purchase behaviour: inter-relationship 总被引:5,自引:0,他引:5
Numerous authors have pointed out the influence of tourism image on consumer behaviour. Tourism image will also exercise some influence on the quality perceived by tourists and on the satisfaction obtained from the holiday experience. This paper focuses on the relationship between the image of a destination as perceived by tourists and their behavioural intentions, and between that same image and the post-purchase evaluation of the stay. We will also examine the relationship between quality and satisfaction and between these variables and the tourist's behaviour variables. We place the accent on a joint analysis of these relationships, using a structural equation model. The results of the empirical study show that tourism image is a direct antecedent of perceived quality, satisfaction, intention to return and willingness to recommend the destination. The role of image as a key factor in destination marketing is thus confirmed. With reference to the other relationships, on the one hand, it is confirmed that quality has a positive influence on satisfaction and intention to return and that satisfaction determines the willingness to recommend the destination. However, the influence of quality on ‘willingness to recommend’ and the influence of satisfaction on ‘intention to return’ cannot be corroborated. In this sense, further research could be necessary. 相似文献

Spot water markets and risk in water supply 总被引:1,自引:0,他引:1
Water availability patterns in semiarid regions are typically extremely variable. Even in basins with a highly developed infrastructure, users are subject to unreliable water supplies, incurring substantial economic losses during periods of scarcity. More flexible instruments, such as voluntary exchanges of water among users, can help users to reduce risk exposure. This article looks at the effects of spot water markets on the economic risk caused by water availability variations. Our theoretical and empirical risk analyses are based on the random profits of water users. Profit probability density functions are formally and graphically characterized for both water sellers and buyers under several possible market outcomes. We conclude from this analysis that, where water supply is stochastic, water markets unambiguously reduce both parties' risk exposure. The empirical study is conducted on an irrigation district in the Guadalquivir Valley (Southern Spain), where there is a high probability of periods of extreme water scarcity. Water demand functions for the district representative irrigators and a spatial equilibrium model are used to simulate market exchanges and equilibrium. This programming model is combined with statistical simulation techniques. We show that the profit probability distribution of a representative irrigator is modified if water exchanges are authorized, leading to risk reductions. Results also indicate that if the market were extended to several districts and users that are subject to varying hydrological risk exposure, extremely low‐profit events would be less likely to occur. In sum, we show that exchanging water in annual spot markets can reduce farmers' economic vulnerability caused by water supply variability across irrigation seasons. These results support the water policy reform carried out in Spain in 1999 to allow for voluntary water exchanges among right holders. 相似文献

Beta as a measure of risk has been under fire for many years. Although practitioners still widely use the CAPM to estimate the cost of equity of companies, they are aware of its problems and are looking for alternatives. A possible alternative is to estimate the cost of equity based on the semideviation, a well-known and intuitively plausible measure of downside risk. Complementing evidence reported elsewhere about the ability of the semideviation to explain the cross-section of returns in emerging markets and that of industries in emerging markets, this article reports results showing that the semideviation also explains the cross-section of Internet stock returns. 相似文献

The DoD annually procures billions of dollars worth of systems, supplies, and services in support of the national military strategy. Faced with budget cuts and other resource constraints, the DoD must transform its procurement process to ensure cost-effective sourcing of critical supplies and services. One aspect of current transformation in the DoD is the use of a strategic sourcing approach for the procurement of services at military installations. Using the Air Force's strategic sourcing process as our context, we developed an optimization model for selecting a set of proposals from among multiple offerors for services to be performed at multiple installations. The selection achieves the most favorable objective by balancing the confidence level in an offeror's past performance with the cost of services to the Air Force. The research findings, which are based on a realistic scenario, demonstrate improvements over the current sourcing process in both overall performance and cost. 相似文献

The paper examines a Lagrange Multiplier type test for the constancy of the parameter in general models with dependent data without imposing any artificial choice of the possible location of the break. In order to prove the asymptotic behaviour of the test, we extend a strong approximation result for partial sums of a sequence of random variables. We also present a Monte-Carlo experiment to examine the finite sample performance of the test and how it compares with tests which assume some knowledge of the possible location of the break. 相似文献

This article presents an open discussion of the processes of urban secession and gentrification in contemporary European cities, arguing that intergroup social dynamics in urban spaces are generally more complex than either extreme mutual avoidance or the colonization of neighbourhoods by the wealthiest groups. We analyse the residential strategies of urban upper‐middle class managers in various European metropolitan areas through in‐depth semi‐structured interviews to argue that these groups develop complex strategies of proximity and distance in relation to other social groups. The development of these ‘partial exit’ strategies takes place through specific combinations of practices that allow groups to select the dimensions they are willing to share with other social groups, and those in which they prefer a more segregated social environment for themselves and their families. The responses of our interviewees were consistently more nuanced and complex than suggested by a simplistic theory about their drive to withdraw from society, forcing us to develop more sophisticated conceptual frameworks to account for the growing prevalence of multi‐layered identities and spheres of reference and solidarity, specific combinations of elective segregation and local involvement, and more active patterns of mobility combined with local embeddedness. 相似文献

The current economic crisis, unsustainable growth, and financial scandals invite reflection on the role of universities in professional training, particularly those who have to manage businesses. This study analyzes the main factors that might determine the extent to which Spanish organizational management educators use corporate social responsibility (CSR) or business ethics stand‐alone subjects to equip students with alternative views on business. A web content analysis and non‐parametric mean comparison statistics of the curricula of undergraduate degrees in all universities in Spain were conducted. The main conclusion of this paper is related to the Bologna effect in Spanish universities. Comparing our results with prior research in this matter, it is demonstrated that the main reason that explains the increase of CSR and ethical education in Spain is the Bologna process and its adaptation to the European Higher Education Area. Also, private universities in Spain are more likely to require an ethics course than public universities. Other factors, such as size, political orientation, or related to CSR chairs are not statistically explanatory of CSR and ethical education. 相似文献
