Mitigating shortage and distribution costs in damaged water networks

Recent events have sparked renewed interest in disaster mitigation for public infrastructures. Presidential Decision Directive 63 identifies water distribution as being among the most vital and vulnerable of our large-scale infrastructures. Water distribution networks are vulnerable to threats such as chemical and biological contamination, cyber attacks on computer-based management systems, and physical destruction from acts of nature and intentional attack. This research develops methods for configuring the undamaged portion of the water network to mitigate the consequences of physical destruction. The approach is to find a hydraulically feasible residual network that can be pressurized to meet the demand of a subset of demand sectors. Demand sectors not pressurized then receive water through truck distribution from pressurized sectors. The objective is to minimize weighted water shortage and water truck distribution costs by identifying sectors to pressurize along with an assignment of unpressurized sectors to pressurized sectors for water delivery by truck. The paper develops an optimization model, describes a solution method, and presents computational results for three example networks.     

How leveraging human resource capital with its competitive distinctiveness enhances the performance of commercial and public organizations

Although scholars agree that complex relationships between organizations' actual human resources (i.e., human capital stock) and means of leveraging these resources may influence performance, little empirical work has tested such propositions directly. We collected two primary data sets from privateand public‐sector organizations in Israel. The multiplicative interaction between perceived human resources capital and distinctive value derived from that HR capital was significantly related to various measures of perceived and objective organizational performance. Having higher levels of human resources capital was strongly associated with performance only when top managers perceived that these resources provided distinctive value in terms of being highly valuable, inimitable, rare, and nonsubstitutable. We discuss the implications of these findings for research on strategic human resource management and the resource‐based view of competitive advantage, as well as for practical efforts to develop firm‐specific human resource capital that is inherently distinctive. © 2005 Wiley Periodicals, Inc.     

Communication skills in accounting education: Perceptions of academics,employers and graduate accountants

Communication skills are central to intellectual interaction between the providers and the recipients of information. The importance of accounting starts with the gathering and processing of information and ends with the communication of processed information. This paper examines the communication skills which employers, academics and graduate accountants consider necessary to the newly graduated accountant. It also identifies and considers the differences in perception which occur between these groups and suggests solutions to the communication gap. This study confirms findings from previous research that new graduate accountants experience communication-related problems in early employment. In addition, it provides evidence that the Australian accounting curriculum has contributed to the development of communication skills. However, the paper highlights the need for the reconsideration of an emphasis on communication skills in the accounting curriculum, a role which arises from the very nature of accounting as the processing and communication of information.     

Choosing to Cofinance: Analysis of Project-Specific Alliances in the Movie Industry

We use a movie industry project-by-project dataset to analyzethe choice of financing a project internally versus financingit through outside alliances. The results indicate that projectrisk is positively correlated with alliance formation. Moviestudios produce a variety of films and tend to develop theirsafest projects internally. Our findings are consistent withinternal capital market explanations. We find mixed evidenceregarding resource pooling, i.e., sharing the cost of largeprojects. Finally, the evidence shows that projects developedinternally perform similarly to projects developed through outsidealliances.     

Does salesperson's customer orientation create value in B2B relationships? Empirical evidence from India

Although value creation in business relationships has taken an important position in the literature, yet scant attention has been paid to the precise nature of creation or destruction of value in b2b customer-oriented selling. Moreover, very few empirical studies in the b2b customer value research have focused on emerging markets, especially the BRIC countries. This study carried out in the context of small and medium sized firms in India, empirically examines from the SOCO perspective (Saxe and Weitz, 1982), value creation in customer-oriented selling, and value destruction in sales-oriented strategies. We model value creation, relationship development, and customer satisfaction as direct and indirect consequences of salesperson's customer orientation. Based on a sample of 249 small and medium sized Indian firms, we show that salesperson's customer orientation directly leads to value creation and relationship development with customers. On the other hand, a sales orientation destroys value, although it may lead to relationship development in the short-term. We also found that customer satisfaction was unrelated to both types of salesperson's orientations. Our study has considerable impact for small and medium sized businesses in emerging BRIC markets such as India, as it throws light on how supplier firms can leverage their salesforce to create value creation with their customers.     

Damages for Breach of Contract: Should the Government Get Special Treatment?

Contracts that involve the government differ from contractsbetween two private parties in that the identity of one of theparties, the government, is subject to change. Given that theincumbent government knows that it might not be in power whenthe contract is completed, it may have an incentive to structurethe contract to make it more difficult for a new governmentto renegotiate it. I show that traditional damage measures usedin contracts between two private parties exacerbate this problem.The reliance damage measure induces the incumbent governmentto enlarge projects beyond the socially optimal level when itfears that a new government will want to cut it back. Expectationdamages suffer from the same defect, though to a lesser extent.     

MANAGERIAL INCENTIVES AND THE PRICE EFFECTS OF MERGERS*

Most analysis of market power assumes that managers are perfect agents for shareholders. This paper relaxes that assumption. When managers of a multi‐product firm exert unobservable effort to improve product quality, there is a trade‐off between providing adequate effort incentives and ensuring sufficient price‐coordination between the product divisions. This makes some intra‐firm price competition optimal, explaining why many multi‐product firms allow for competition between divisions. When there are effort spillovers, the optimal amount of price competition can be as great as when the products are under separate ownership. Even with some profit‐sharing, intra‐firm price competition can reduce quality‐adjusted price, which has important implications for antitrust policy.     

Information transmission between the Gulf equity markets of Saudi Arabia and Bahrain

This paper examines whether the emerging Gulf markets of Saudi Arabia and Bahrain in conjunction with the US market exhibit cointegrating relationship. Additionally, the transmission of information and volatility spillover between the Gulf markets is explored using a bivariate EGARCH model. We find that although the markets are not cointegrated, the Gulf markets do share information flows. Specifically, we observe an asymmetric spillover of volatility from the smaller though more liberal and accessible Bahraini market to the larger and less accessible Saudi market. The observed difference in information processing may partly be due to a well-developed Bahraini financial sector that encourages wider participation by international investors who play a significant role in assimilating new information.     

Two polar cases of dynamic stability: voluntary exchange and income redistribution

Summary. It is known that when voluntary exchange is permitted at disequilibrium, dynamic stability may fail because of lack of liquidity. In this paper it is shown that when the economy runs out of liquidity dynamic stability can still be restored by means of a planning procedure of redistributing personal incomes.Received: 30 May 2003, Revised: 20 January 2005, JEL Classification Numbers: D01, D50.I wish to thank a referee for helpful comments.     

Optimal bank asset and liability management with financial futures

This paper presents a model for optimal bank asset and liability management with financial futures. This model is a multiperiod linear programming model based on Markowitz portfolio theory. Given the bank's initial position, its economic forecasts, and the constraints under which it operates, the model can help a bank's senior executives determine the current and expected future balance sheet composition and financial futures position which will minimize the bank's operating risks and which will meet the bank's expected profits goal with the minimum possible profits risk. By parametrically varying the expected profits goal, the model will generate the set of risk-return efficient decisions. Bankers need then examine only the set of efficient decisions to choose their optimal solution. A simplified example is used to illustrate the application of our model and to demonstrate that banks that use financial futures in asset and liability management can obtain better results than banks that do not use financial futures.
