This study examined the ways in which perceived constraints and self-efficacies associated with participation in active recreation influenced Hong Kong and Australian university students' interest, intention, and participation in regular active recreation. The study indicated that perceived constraints have weak negative effects whereas self-efficacies have stronger positive effects on students' interest, intention, and participation in regular active recreation. Time efficacy, persistence efficacy, and activity efficacy emerged as important indirect motivators of active recreation engagement. The influences of constraints and self-efficacies on active recreation participation mainly occurred indirectly through adjustments in participation interest and intention. 相似文献
In this paper, we present the results of a Learning-to-Forecast Experiment (LtFE) where we eliciting short- as well as long-run expectations regarding the future price dynamics in markets with positive and negative expectations feedback. Comparing our results on short-run expectations with the LtFE literature, we prove that eliciting long-run expectations has no impact on the price dynamics nor on short-run expectations formation. In particular, we confirm that the Rational Expectation Equilibrium (REE) is a good benchmark only for the markets with negative feedback. Interestingly, our data show that while the term structure of the cross-sectional dispersion of expectations is convex in positive feedback markets, it is concave in negative feedback markets. Differences in the slope of the term structure stem from diverse degrees of uncertainty regarding the evolution of prices in the two feedback systems: (1) in the negative feedback system, the convergence of the price to the REE reflects a tendency for coordination of long-run expectations around the fundamental value; (2) conversely, oscillatory price dynamics observed in the positive feedback system is responsible for the diverging pattern of long-run expectations. Finally, we propose a new measure of heterogeneity of expectations based on the scaling of the dispersion of expectations over the forecasting horizon.
Despite major improvements in women's labour market attachment, women still earn considerably less than men. International research shows that the persistence of the gender pay gap may be due to the fact that although the gap in characteristics between men and women is diminishing, changes in the wage structure counteract this change. This article will study whether this ‘swimming upstream’ phenomenon is also playing a role in the rather slow convergence between male and female wages in the Netherlands. Our results indicate that this is not the case; most of the changes in the Dutch wage structure have been rather favourable to women. The lacking convergence in wages has to be explained from the fact that despite the favourable changes, the Dutch wage structure still contains a considerable implicit gender bias. 相似文献
This article analyzes the managing of high-tech projects in complex and dynamic settings. Building on recent developments in organization theory and knowledge management, we focus on the importance of understanding the ways in which project-centered activities are shaped in time and space, both in the organization itself and in a wider context embracing customers, consultants and suppliers. A longitudinal case study including semi-structured interviews, observations and secondary data will substantiate our findings. The study offers both theoretical and practical insights suggesting that projects are exposed to a varying degree of complexity and dynamics, calling for different managerial approaches. The analysis shows that boundary spanning has many dimensions that have to be considered in the management of projects in space and time. The article concludes by suggesting seven analytical categories for analyzing and understanding projects in their spatial and temporal contexts. 相似文献
Over the last decade, markets for investments have changed in Europe. Consumers have become more aware of ethical standards and violations of social values and norms. While in some countries, such as the United States, this change took place decades ago, the market for ethical investment in Europe is still at an early stage. The present study investigates the underlying motives for ethical assets of consumers in early-stage markets. Using seven interviews with financial experts and five focus groups with ethical and conventional investors, we examine how investors view ethical investment, how ethical investors are described in terms of socio-demographics and personality characteristics, and which attitudinal factors are related to ethical investment behaviour. Interviews and focus groups are recorded and qualitatively analysed according to grounded theory. Ethical investment is found to be characterised through negative and positive ethical criteria. Our findings demonstrate how essential it is for ethical investors to lead a certain lifestyle driven by particular ecological and social values. Attitude theory serves to explain ethical investment behaviour. Conclusions for the marketing of ethical investment funds and for future research are drawn. 相似文献
The problems caused by water scarcity demand important changes in the criteria and objectives of water policies. The agricultural sector in Spain consumes up to 80% of all available hydric resources and the need to increase the efficiency of current uses of water in the agricultural sector is at the core of the country's national water policy. One alternative would be to resort to water pricing policies with the aim of providing incentives to save water consumption although it would inflict a certain degree of income losses to the farmers and raise the revenue collected by the water authorities. The objective of this research is to analyze the effect caused by the application of different water pricing policies on water demand, farmers' income and the revenue collected by the government agency. To undertake this analysis a dynamic mathematical programming model has been built that simulates farmers' behavior and their response to different water pricing scenarios. Empirical application of the model has been carried out in several irrigation districts in Spain covering varied farm regions and river basins. Results show that the effects of alternative pricing policies for irrigation water are strongly dependent on regional, structural and institutional conditions and that changing policies produce distinct consequences within the same region and water district. Thus, equivalent water charges would create widespread effects on water savings, farm income and collected government revenue across regions and districts. 相似文献
The government wants an infrastructure‐based public service to be provided. First, the infrastructure has to be built; subsequently, it has to be operated. Should the government bundle the building and operating tasks in a public–private partnership? Or should it choose traditional procurement (i.e., delegate the tasks to different firms)? Each task entails unobservable investments to come up with innovations. It turns out that, depending on the nature of the innovations, bundling can either stimulate or discourage investments. Moreover, we find that if renegotiation cannot be prevented, public–private partnerships might lead the government to deliberately opt for technologically inferior projects. 相似文献
Many instrumental variable (IV) regressions include control variables to justify (conditional) independence of the instrument and the potential outcomes. The plausibility of conditional IV independence crucially depends on the timing when the control variables are determined. This paper works through different IV models and discusses the (conditions for the) satisfaction of conditional IV independence depending on whether the control variables are measured prior to or after instrument assignment. To illustrate the identification issues, we consider the Vietnam War draft risk as instrument either for veteran status or education to evaluate the effects of these variables on labour market and health outcomes. Our empirical analysis based on the ‘Young Men in High School and Beyond’ survey suggests that commonly used conditional IV strategies to estimate the impact of draft induced military service or education may be severely biased due to the use of improper controls. 相似文献
