Encouraging water use efficiency and water conservation is one of the primary goals of water utility companies nationwide. This study estimates price elasticity of residential water demand to measure the responsiveness of water use to price changes, particularly for high water users. Household-level water use data for high residential water users from Central Florida were analysed using 3-stage least square (3SLS). Estimated price elasticity ranges between ?0.07 and ?0.14. This price elasticity estimate is below most of the estimates reported in the literature (in absolute value). The results imply that for price strategies to be effective in managing water demand of high residential water users, a significant price increase would be needed. Overall, this study highlights the importance of designing water conservation policies tailored to specific groups of customers, and the importance of using these strategies effectively and fairly for different customer groups. 相似文献
The public sector has grown dramatically over the past few centuries in many developed countries. In this article, we use wavelet methods to distinguish between two leading explanations for this growth – Wagner’s law and the displacement effect. In doing so, we use the long-term data of 10 OECD countries for a maximum time span of 1800–2009. We find that the validity of Wagner’s law is likely to vary strongly over time for each country. A roughly similar feature in most of the countries is that the law is less valid in the earliest stage of economic development as well as in the advanced stages, with the validity tending to follow an inverted U-shaped pattern with economic development. Further, our results indicate that the long-run growth of government size cannot be adequately explained by Wagner’s law. On the other hand, the displacement effect appears to account for the bulk of the growth in most of the countries. 相似文献
This study aimed to analyse the impact that the financial features and characteristics of the ownership structures of international companies exert on the performance of their internationalization process, as perceived by managers, and attempted to detect differences between family firms (FF) and nonfamily firms (non-FF). In addition, the impact of these characteristics and others related to FF, such as family ownership and generation, on the perceived performance of their internationalization is analysed. Based on a sample of Spanish companies with direct investment in China, the results indicated that, from the managers’ perspective, being an FF and having lower financial leverage exerted a positive effect on the performance of the internationalization process. Moreover, the study proved that this performance was strongly and positively related to the financial results of the company, and this positive effect was even stronger in the case of FF. Finally, the findings also showed that FF with a higher involvement of the family in their ownership recognized a better performance of their internationalization process. These results will be useful for companies that are considering the value of internationalization as a strategy to improve or maintain their financial results, and they also highlight certain differences between FF and non-FF. 相似文献
This study examines the private consumption benefits of sports attendance using revealed and stated preference data from 28 Football Bundesliga teams across three divisions. Survey respondents were presented with positive (sporting success) and negative (management failure) scenarios and asked for the number of game trips if each scenario occurred. The results of a pooled random effects Poisson model show that travel costs and ticket price have a significant negative effect on the number of home game trips. The weighted consumer surplus per game trip including travel costs and ticket prices is €345. Consumer surplus per game trip was found to change by €41 (first division) and €98 (second and third division) if the positive scenario occurred and by €39 if the negative scenario occurred. 相似文献
In this article, the authors discuss the use of Federal Reserve Economic Data (FRED) statistics to teach the concept of price elasticity of demand in an introduction to economics course. By using real data in its computation, they argue that instructors can create a value-adding context for illustrating and applying a foundational concept in economics. Additionally, this pedagogical strategy contributes to developing an expected proficiency for economics majors related to “interpreting and manipulating data” (Hansen 2009, 2012). The authors provide step-by-step instructions on how to use FRED to compute the price elasticity of demand for motor vehicle fuels and gasoline as well as examples of in-class discussion questions and take-home assignments related to this instructional technique. 相似文献
This article examines the quality of China’s preliminary announcements of the quarterly GDP. We modify the tests for unbiasedness and efficiency by incorporating the Fourier approximation to capture the effect of the state of the economy, and employing the Kiefer, Vogelsang and Bunzel (KVB) approach, developed by KVB in 2000 to reconstruct the tests to improve the finite sample properties. The results show that: (1) there is no enough evidence to support that the preliminary and first revised data are unbiased and efficient; (2) there exist systematic errors related to the state of the economy, and hence information about the state of the economy was not incorporated into the GDP data. Furthermore, we find that there is a possibility that these systematic errors associated with the stages of the business cycle may offset each other, and there is also a possibility that there exist offsetting errors in the underlying components of GDP. 相似文献
This paper investigates the effects of China on the BRIS countries, namely Brazil, Russia, India and South Africa. We identify Chinese supply and demand shocks and assess their transmission to BRIS in a structural dynamic factor model framework estimated over the period 1995Q2‐2009Q4. The findings show that Chinese supply shocks are more important than its demand shocks. Supply shocks produce positive and significant output responses in all BRIS countries. And while these supply shocks have a permanent impact on the BRIS countries, the effects of demand shocks are short‐lived. Both supply and demand shocks are transmitted through trade rather than financial linkages. However, the responses of the BRIS countries are heterogeneous and therefore require country‐specific policy responses. 相似文献
This paper interprets the pressure to raise Palestinian-Israeli women’s labor force participation within the unfolding neoliberal project in Israel, arguing that women’s stalled workforce integration reflects embedded economic rationality. Poor infrastructure and discriminatory policies, combined with Israel’s rapid economic privatization, set contradictory expectations for Palestinian-Israeli women: their opportunity-cost calculations include entitlements to economic protection alongside obligations to provide expenditure-saving domestic labor. Yet growing pressure and desire to join the paid workforce suggest that the gender contract may be changing. This cultural schema, which links women’s economic strategizing to their sense of feminine propriety, is transforming as part of a broader transition to a market-led gender regime, with the paradoxical effect of encouraging women’s employment while simultaneously impoverishing them. By dwelling on the dialectics of culture and the structure of work opportunities, and women’s agency, this paper aims to resolves an impasse in the current debate on women’s low workforce participation. 相似文献
Aims: Inflammatory bowel disease (IBD) (e.g. ulcerative colitis [UC] and Crohn’s disease [CD]) severely impacts patient quality-of-life. Moderate-to-severe disease is often treated with biologics requiring infusion therapy, adding incremental costs beyond drug costs. This study evaluates US hospital-based infusion services costs for treatment of UC or CD patients receiving infliximab or vedolizumab therapy.
Materials and methods: A model was developed, estimating annual costs of providing monitored infusions using an activity-based costing framework approach. Multiple sources (published literature, treatment product inserts) informed base-case model input estimates.
Results: The total modeled per patient infusion therapy costs in Year 1 with infliximab and vedolizumab was $38,782 and $41,320, respectively, and Year 2+, $49,897 and $36,197, respectively. Drug acquisition cost was the largest total costs driver (90–93%), followed by costs associated with hospital-based infusion provision: labor (53–56%, non-drug costs), allocated overhead (23%, non-drug costs), non-labor (23%, non-drug costs), and laboratory (7–10%, non-drug costs).
Limitations: Limitations included reliance on published estimates, base-case cost estimates infusion drug, and supplies, not accounting for volume pricing, assumption of a small hospital infusion center, and that, given the model adopts the hospital perspective, costs to the patient were not included in infusion administration cost base-case estimates.
Conclusions: This model is an early step towards a framework to fully analyze infusion therapies’ associated costs. Given the lack of published data, it would be beneficial for hospital administrators to assess total costs and trade-offs with alternative means of providing biologic therapies. This analysis highlights the value to hospital administrators of assessing cost associated with infusion patient mix to make more informed resource allocation decisions. As the landscape for reimbursement changes, tools for evaluating the costs of infusion therapy may help hospital administrators make informed choices and weigh trade-offs associated with providing infusion services for IBD patients. 相似文献
Unemployment in South Africa has multiple causes. This article uses a district pseudo-panel to estimate the elasticity of labour demand, labour supply and unemployment with respect to wages. We assess whether hiring decisions are more sensitive to increases in wages of low-paid workers than high-paid workers, and whether wage growth prompts entry into the labour market. These channels combine to result in the positive causal effect of wage growth on unemployment. The research investigates whether these effects are dominated by districts in which unionisation rates are high and employment is concentrated in large firms. Wage growth of middle-paid to highly paid workers – as opposed to low-paid workers – reduces local labour demand and raises local unemployment. Bargaining arrangements correspond closely to the spatial wage distribution; in turn, a large part of the impact that wage growth has on labour market outcomes is determined by these wage-setting institutions. 相似文献
