Urban water management: optimal price and investment policy under climate variability*

Australian urban water utilities face a significant challenge in designing appropriate demand management and supply augmentation policies in the presence of significant water scarcity and climate variability. This article considers the design of optimal demand management and supply augmentation policies for urban water. In particular, scarcity pricing is considered as a potential alternative to the predominant demand management policy of water restrictions. A stochastic dynamic programming model of an urban water market is developed based on data from the ACT region. Given a specification of the demand and supply for urban water state dependent optimal price and investment policies are estimated. The results illustrate how the optimal urban water price varies inversely with the prevailing storage level and how the optimal timing of investment differs significantly between rain dependent and rain independent augmentation options.     

Control and commitment HR practices,job satisfaction and turnover intentions: a comparison between local and multinational firms in China

There is a growing body of literature and debate around control versus commitment human resource management (HRM) systems and their impacts on employees. However, the impacts of these constructs have not been widely examined in more emerging economies. Taking a specific sample of educated professionals working for multinational and local firms in China, this study investigated employee perceptions of control and commitment HR practices, job satisfaction and turnover intentions. A total of 311 respondents completed a structured survey questionnaire. Results revealed that those working for multinational firms reported more positive perceptions of their employers' control and commitment HR practices. In multinational firms, the use of commitment HR practices predicted lower intentions to leave. However, in domestic firms a lack of control HR practices predicted higher turnover intentions. Theoretically, the study adds to discussions about the nature and roles of these constructs, their impacts on HR outcomes and how institutional mechanisms might shape the degree of HRM homogeneity and hybridity across organizations in China. Practically, the study provides guidance to international and local firms on how to improve their HRM effectiveness to achieve a higher retention of their most talented professionals.     

Is provision for old-age the main saving motive of the future?—An empirical analysis for Germany

The demographic development is a big challenge for public and private pension schemes. In this context it is important to know if individuals recognize the problem and if this reflects on their attitude towards private pension schemes. The aim of our study is to analyze the general importance of the saving motive old-age provision as well as its impact on the ownership and the demand for old-age provision linked insurance products. We apply panel analysis techniques to show among others that old-age provision as a saving motive primarily impacts the ownership and the demand for annuities. On the contrary to this result, the state funding seems to be the dominant motivation behind the decision to buy state promoted annuities.     

Discourses surrounding the evolution of the IASB/FASB Conceptual Framework: What they reveal about the “living law” of accounting

The International Accounting Standards Board (IASB) and the Financial Accounting Standards Board (FASB) recently published the final version of Chapter 1 of their joint Conceptual Framework for Financial Reporting (IASB/FASB, 2010). In this article, we focus on two of the key issues addressed in Chapter 1: stewardship and the definition of the primary user groups of financial statements. To address the discourses surrounding the evolution of Chapter 1, we introduce the concept of “living law” from sociological jurisprudence into accounting scholarship. We first trace the role of stewardship/accountability in the evolution—from antiquity to the present day—of the living law of accounting. We then explore the origin, nature, and implications—from a living law perspective—of the moral traditions associated with stewardship/accountability. Our analysis suggests that stewardship has been, and continues to be, embedded in the living law of accounting—notwithstanding the formal pronouncements of standard setters. We also examine the social accounting project from a living law perspective and we suggest that such an analysis provides new possibilities for addressing core social accounting concerns. We conclude by arguing that, particularly in light of the far reaching impact of the neoliberal agenda, there is an urgent need for scholars in both contemporary “social” and “mainstream” accounting to recognize and build upon their shared living law heritage rooted in the age-old traditions of stewardship/accountability.     

Business travellers' perception of service quality: a prefatory study of two European city centre hotels

The business traveller contributes significantly to the turnover of the hotel industry and, with the globalisation of business, this sector shows signs of increasing growth. Service quality has now become one of the main factors used to gain competitive advantage, thus the industry must focus more specifically on the needs and expectations of its business customers. The aim of this paper is to focus on the business travel market and more specifically on the comparison of two hotels in two European cities, Brussels and Manchester. This area of research has not been attempted before and will provide an interesting comparison with findings in USA. A literature review identified the relevant attributes used to measure service quality, which were utilised to design a questionnaire, distributed to customers in a five star hotel in Manchester and in Brussels. The primary data obtained were then compared with the findings of other researchers. The analysis indicated that Brussels scored the majority of the attributes more highly (many significantly) than did Manchester. This may be influenced by the international profile of the Brussels respondents who tended to travel on business more frequently than the Manchester sample. The comparisons with the USA surveys found some inconsistencies that might be attributed to societal differences.Copyright © 2001 John Wiley & Sons, Ltd.     

Optimal insurance under maxmin expected utility

We examine a problem of demand for insurance indemnification, when the insured is sensitive to ambiguity and behaves according to the maxmin expected utility model of Gilboa and Schmeidler (J. Math. Econ. 18:141–153, 1989), whereas the insurer is a (risk-averse or risk-neutral) expected-utility maximiser. We characterise optimal indemnity functions both with and without the customary ex ante no-sabotage requirement on feasible indemnities, and for both concave and linear utility functions for the two agents. This allows us to provide a unifying framework in which we examine the effects of the no-sabotage condition, of marginal utility of wealth, of belief heterogeneity, as well as of ambiguity (multiplicity of priors) on the structure of optimal indemnity functions. In particular, we show how a singularity in beliefs leads to an optimal indemnity function that involves full insurance on an event to which the insurer assigns zero probability, while the decision maker assigns a positive probability. We examine several illustrative examples, and we provide numerical studies for the case of a Wasserstein and a Rényi ambiguity set.
