We reexamine the methods used in estimating comovements among US regional home prices and find that there are insufficient moments to ensure a normal limit necessary for employing the quasi‐maximum likelihood estimator. Hence we propose applying the self‐weighted quasi‐maximum exponential likelihood estimator and a bootstrap method to test and account for the asymmetry of comovements as well as different magnitudes across state pairs. Our results reveal interstate asymmetric tail dependence based on observed house price indices rather than residuals from fitting autoregressive–generalized autoregressive conditional heteroskedasticity (AR‐GARCH) models.  相似文献

This paper provides evidence of how the long-term unemployed react to the threat of running out of unemployment insurance (UI) after receiving it for nearly 4 years. To identify the effect of UI exhaustion, we make use of a 1999 Danish legislative change that progressively reduced potential benefit duration from 5 to 4 years. We find that shortening UI duration hastens the transition to employment throughout the unemployment spell up to benefit exhaustion even if it occurs as long as 4 years later. However, although the proportional effect is large, it is small in absolute value.  相似文献

Numerous alternative farming systems are proposed as solutions to the sustainability challenges of today's conventional farming systems. In this paper, we review the production, environmental, and socioeconomic performance of three widely discussed and promoted alternative farming systems—organic, smallholder, and urban agriculture. We show that both organic and smallholder agricultures have some benefits, but also entail important trade‐offs; organic has environmental benefits, and also livelihood, health, and nutritional benefits for producers and consumers, but is hampered by lower yields and higher prices. Smaller farms have higher yields and host higher biodiversity, but are hampered by lower incomes to farmers. Urban agriculture can take some pressure off rural landscapes, provide nutritional benefits to the urban poor, and engage urban dwellers in addressing food system challenges, but it simply cannot scale up to be a substantial solution in and of itself. We suggest that instead of focusing on alternative systems, we should identify pathways to sustainable farming for all systems, reforming conventional systems where they perform poorly, and transitioning to alternative systems in contexts where they perform best.  相似文献

We present results from a recent experiment conducted in Switzerland that studies the effects of a temporary change in the mode of travel to work on travel happiness and mode switching. The primary aim is to study the dynamics in travel satisfaction ratings obtained before and after the intervention. Two behavioral mechanisms driving the change in satisfaction ratings are analyzed. The first one is that satisfaction ratings are influenced by reference points. The second mechanism is that satisfaction ratings are affected by cognitive awareness, whereby the disruption of routine travel conditions makes people think more fully about their travel happiness with different modes of transportation.It is found that the measure of satisfaction with the commute by car obtained right after the temporary intervention is significantly different from the measure obtained before the intervention, and both behavioral hypotheses are supported by the pattern of change in satisfaction ratings. The policy and modeling relevance of different well-being measures obtained at different points in time is discussed.As to mode switching, none of the 30 participants switched completely to public transportation after the intervention but a number of them continued to commute occasionally by public transportation. The relationship between mode switching and satisfaction and the implications of this intervention for public transportation agencies and other organizations interested in behavioral modification are discussed.  相似文献

This article investigates whether there are Granger causal relationships between broadband penetration, degree of urbanization, foreign direct investment and economic growth using a panel data set covering the G-20 countries for the period 1998–2011. Using our multivariate framework, we first find that all of the variables are cointegrated. Our findings further reveal a network of causal connections between the variables including short-run bidirectional causality between broadband penetration and economic growth among the more developed countries within the G-20. On the other hand, for the developing countries within the G-20, there is evidence of unidirectional causality from economic growth to broadband penetration.  相似文献

This study measures cost inefficiency for government school in New South Wales, Australia using a two‐stage data envelopment analysis (TSDEA) model and the inefficiency‐effects model (Battese & Coelli, 1995). The study found overall primary schools are 75 per cent and secondary schools are 89 per cent cost efficient. However, cost efficiency for primary schools has decreased and for secondary schools has increased marginally over the study period. The study found that social disadvantage in primary schools exerts a strong negative impact on students’ achievement scores causing inefficient use of available resources. For secondary schools no such conclusive relationship is observed.  相似文献

The present paper considers the issues surrounding the social, professional and family (re‐) integration of end‐of‐career professional athletes in France. Drawing on the case of French rugby player Marc Cécillon, a former captain of the national team whose descent into alcoholism culminated in his conviction for murder of his wife in August 2004, it examines how sports institutions fail to meet athletes' aspirations and needs for support. Drawing on a series of interviews with representatives of sports institutions and analysis of print media coverage, the research investigates the issues surrounding career‐change difficulties for professional athletes. It demonstrates through the story of Marc Cécillon why the career of professional sportsmen and women cannot be divorced from their social trajectory. Rather than acknowledging this, however, the sports institutions concerned are seen to attribute blame for any ills affecting French rugby to exterior causes, such as individual weakness. By rejecting responsibility in this way the sporting ‘family’ falls apart, removing any support system and denying athletes the information and guidance necessary to manage their career change effectively. This is particularly significant for team players, who have been in a subservient position in relation to their clubs and can therefore suffer identity uncertainty from this lack of guidance. The case study suggests that French sports institutions do not play their role in preparing athletes for the realities of a new life based on different values and different social relations.  相似文献

Traditional brick-and-mortar companies are embracing the use of self-service technology (SST) to enhance the services they offer and to gain customer loyalty. The objectives of doing so are to stay at the forefront of today’s marketplace and improve service, efficiency, and profitability. However, SST directly eliminates the traditional service encounter from which luxury hotels benefit. With the rising popularity of SST and benefits it brings to both hoteliers and customers contradicting the importance of the personal service encounter to luxury hotel brands, it is critical for hoteliers to learn about the importance of SST and luxury brand identity in order to bring the greatest satisfaction to both parties. This article examines business travelers’ perceptions of SST adoption by luxury hotel brands in Hong Kong. The results emphasize the importance of both personal service and SST in satisfying customer needs and in increasing profitability.  相似文献

Economists are of the view that tourism leads to economic development just like human and physical capital and exports. A few studies have discussed this issue empirically. The current study aims to estimate the long-run relationship between income from tourism and the economic growth of Pakistan by using the annual time series data of 1971–2008, and by employing the Johansen Juselius cointegration, autoregressive distributed lag model and rolling windows bounds testing approach to check the stability of the model. The results confirm the long-run relationship between income from tourism and economic growth and explain that income from tourism has led economic growth in Pakistan except in the years 2006, 2007, and 2008.  相似文献
