By using panel data analysis across 368 water utilities in Mexico over the period 2010–2014, we find that small firms are more efficient than medium and large providers and that increasing production is associated with less efficiency. Billing, income collection and profitability are relevant factors to improve efficiency. Medium and large firms require to measure consumption by service with meters in order to increase efficiency, while small firms do not require it.  相似文献

In this paper we consider the problem of hedging an arithmetic Asian option with discrete monitoring in an exponential Lévy model by deriving backward recursive integrals for the price sensitivities of the option. The procedure is applied to the analysis of the performance of the delta and delta–gamma hedges in an incomplete market; particular attention is paid to the hedging error and the impact of model error on the quality of the chosen hedging strategy. The numerical analysis shows the impact of jump risk on the hedging error of the option position, and the importance of including traded options in the hedging portfolio for the reduction of this risk.  相似文献

ABSTRACT

Digital assistants (e.g., Apple’s Siri, Amazon’s Alexa, Google’s Google Assistant) are highly complex and advanced artificial intelligence (AI) based technologies. Individuals can use digital assistants to perform basic personal tasks as well as for more advanced capabilities. Yet, the functional and topical use of a digital assistant tends to vary by individual. This study reflects the contextual experiences of the respondents. At present, there is little empirical evidence of customer satisfaction with digital assistants. PLS-SEM was used to analyse 244 survey responses to examine this research gap. The results confirmed that expectations and confirmation of expectations have a positive and significant relationship on customer satisfaction with digital assistants. This study provides evidence that customer expectations are being satisfied through the digital assistant interaction experience. As firms integrate digital assistants into their operations, they must help customers properly define what to expect from the firm’s interactive experience.  相似文献

This study explores corporate social responsibility (CSR) by conducting a cross-cultural analysis of communication of CSR activities in a total of 16 U.S. and European corporations. Drawing on previous research contrasting two major approaches to CSR initiatives, it was proposed that U.S. companies would tend to communicate about and justify CSR using economic or bottom-line terms and arguments whereas European companies would rely more heavily on language or theories of citizenship, corporate accountability, or moral commitment. Results supported this expectation of difference, with some modification. Specifically, results indicated that EU companies do not value sustainability to the exclusion of financial elements, but instead project sustainability commitments in addition to financial commitments. Further, U.S.-based companies focused more heavily on financial justifications whereas EU-based companies incorporated both financial and sustainability elements in justifying their CSR activities. In addition, wide variance was found in both the prevalence and use of specific CSR-related terminology. Cross-cultural distinctions in this use create implications with regard to measurability and evidence of both strategic and bottom-line impact. Directions for further research are discussed. Laura P.

In the past decade, Chinese outward foreign direct investment (OFDI) has become a major element of global capital flows. As a consequence, recent years have witnessed an increasing growth in the number of papers focusing on Chinese companies “going global.” This paper reviews 112 empirical papers focusing on Chinese OFDI that were published in major scholarly journals between 2002 and 2014. We report on individual and institutional contributions, citations, the theories and methods used and the research topics. We also identify the research gaps and discuss the implications of our literature review for future theory building.  相似文献

ABSTRACT

While most consumers today feel concerned by environmental issues, the consumption of hot beverage in disposable cups remains very important. In this study, we use influence strategies related to social norms to reduce these behaviors and get consumers to consume their hot beverage in reusable cups. 14373 orders were analyzed and demonstrate that normative messages can be effective to change consumer behavior toward a more responsible choices.  相似文献

There is little doubt that Brexit would have significant implications for UK agriculture, a sector with strong trade links to the EU and strong reliance on CAP income support. This article reports preliminary results from employing a Computable General Equilibrium Model, a Partial Equilibrium Model and Farm Level Models to explore selected trade and domestic policy scenarios post‐Brexit. These allow for the estimation of changes in producer prices, production and farm incomes against a baseline scenario of continued EU membership. Under a Free Trade Agreement with the EU, agricultural impacts are relatively modest. By contrast, unilateral removal of import tariffs has significant negative impacts on prices, production and incomes. Adoption of the EU's WTO tariff schedule for all imports favours net importers (e.g. dairy) and harms net exporters (e.g. sheep). Given the strong dependence of most UK farms on direct payments, their removal worsens negative impacts of new trade arrangements and offsets positive impacts. Impacts vary across different types and sizes of farm, but also regionally. However, the period of adjustment to new trade and domestic policy conditions may prove very challenging for a large number of farm businesses.  相似文献

Food Stamp Benefits and Child Poverty   总被引:2,自引:0,他引:2  
In 2000, 8.8 million children lived in households participating in the Food Stamp Program, making this assistance program a crucial component of the social safety net. Despite its importance, little research has examined food stamps' effect on children's overall well-being. Using the Current Population Survey from 1989 to 2001, we consider the impact of food stamps on three measures of poverty—the headcount, the poverty gap, and the squared poverty gap. We find that in comparison to the headcount measure, food stamp benefits lead to large reductions in the poverty gap and squared poverty gap measures.  相似文献

Can radical political‐economic transformation be achieved by electoral regimes that have not thoroughly reconstructed the state? Contemporary Venezuela offers an optimal venue for examining this question. The Chavista movement did not replace the previous state: instead, its leaders attempted to reform existing state entities and establish new ones in pursuit of its transformation agenda. It has also used its oil wealth to support cooperatively‐oriented economic activity, without necessarily fundamentally altering the property structure. Thus, the social change‐oriented political economy exists alongside the traditional one. Focusing on agrarian transformation, we examine ethnographically how these factors have impacted the state's capacity to attain its goal of national food sovereignty. We find that the state's ability to accomplish this objective has been compromised by lack of agency‐level capacity, inter‐agency conflict and the persistence of the previously‐extant agrarian property structure. These dynamics have influenced the state to shift from its initial objective of food sovereignty to a policy of nationalist food security.  相似文献
