On the adequacy of single‐stock futures margining requirements

Unlike the traditional futures contract risk‐based approach to margining, new security futures contracts are margined under a strategy‐based margining system similar to that which applies in the equity options markets. As a result, these new margin requirements are potentially much less sensitive to changes in market conditions. This article performs a simulation to evaluate whether these alternative margining methodologies can be expected to produce comparable outcomes. The analysis suggests that a 1‐day settlement period will likely lead to collection of customer margins that are virtually always greater than that which its traditional risk‐based counterpart would require. A 4‐day settlement period would lead to margin requirements that both significantly under‐ and overmargin relative to a comparable risk‐based system. This study argues that exchanges may approach the preferred probability of customer exhaustion by managing margin settlement intervals. Thus, the new strategy‐based rules, in and of themselves, will not necessarily inhibit new security futures trading activity. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:989–1002, 2003     

OPTIONAL REAL-TIME PRICING OF ELECTRICITY FOR INDUSTRIAL FIRMS

Abstract. This paper proposes a pricing mechanism, optional real-time pricing (RTP), with day-ahead hourly prices, that exploits the potential offered by a competitive wholesale power market. When an electric utility offers the option to its industrial customers, the retail prices are based on an existing Hopkinson tariff and expectations as to the wholesale market's next-day hourly spot prices. The proposed RTP mechanism is Pareto-superior to the tariff in that it assures both the utility and the customer of profits that will be at least as great as under the tariff.     

Do Borrowers Make Rational Choices on Points and Refinancing?

Utilizing individual mortgage data, we find that borrowers with points are less likely to refinance, and when they do, they take longer to refinance. This finding supports the separating equilibrium prediction of earlier studies that borrowers with higher (lower) refinancing costs self‐select into mortgages with higher‐point/lower‐rate (lower‐point/higher‐rate) loans.     

The ‘old’ and ‘new’ competition and Malaysian manufacturing firms: a case study

The majority of empirical studies dealing with production processes, work organization and industrial relations practices have been conducted in advanced industrial nations. This article reports on a study of the changing nature of work organization and industrial relations policies in the developing economy of Malaysia. It explores the broad patterns of change in human resource management, technology and work organization among Malaysian manufacturing firms in the context of Best's ‘old’ and ‘new’ competition. The question that arises is: does the evidence reveal that Malaysia is embracing elements of the ‘new competition’, or is it still locked into a regime of mass production, or both? The article argues that the ‘old’ and the ‘new’ competition should not be treated as a simple, straightforward duality model of development. The distinction between the two approaches is sometimes blurred and not so clear-cut. The case study observes that both systems could be operating side by side at the same time within an organization. Since the Malaysian manufacturing sector is expected to shift from simple assembly and process-type operations using labour-intensive techniques to the more advanced and higher value-added industries, greater investment in HRD to upgrade the skills of the work-force and the adoption of appropriate industrial relations policies that emphasize decentralization, greater employee involvement and continuous innovation will become crucial. To be able to compete successfully in the global economy would require a change in focus in the adoption of industrial relations and human resource development policies. For Malaysia to realize its aspiration to become an industrialized and developed nation by the year 2020 would require radical changes in those policies within the context of an integrated approach to economic and industrial planning.     

If you play well they will come—and vice versa: bidirectional causality in major‐league baseball

The Granger‐causality test is applied to the annual attendance and win‐percentage data for 29 major‐league teams. It is shown that bidirectional causality exists for these teams and that there are some essential differences between the original 10 of 16 franchises that comprised the majors in 1903 and the six that relocated between 1953 and 1961. Some differences and some similarities are also seen in the parameter estimates for both blocs of teams, the relocated teams, and seven long‐lived expansion franchises. Finally, the parameter estimates are manipulated to yield noise‐free equilibrium estimates for both attendance and performance. In tandem, these two sets of estimates provide fodder for speculation as to the futures of each of the extant 23 franchises considered here. Copyright © 2007 John Wiley & Sons, Ltd.     

Membership size in the educable cooperative facing uncertain demand

This article explicitly incorporates layoff and hiring costs into a discretetime dynamic model with stationary demand uncertainty, in which managers in a cooperative learn something about the demand process over time, and anticipate learning something about that process. It is shown how the opportunity to learn affects initial membership size and how the knowledge gained induces changes in membership, as well as how risk preferences impact on membership size at any point in time.     

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.     

What explains the lack of monetary policy influence on bank holding companies?

In this paper, we investigate how monetary policy innovations affect the equity returns of bank holding companies (BHCs). We also examine bank characteristics to determine what explains the cross-sectional and time-series variation in the returns' sensitivity. Similar to non-financial firms, we find that only unanticipated components affect bank equity returns; however, this effect is absent in the second half of our sample period. Smaller, less liquid banks have higher sensitivity; a higher ratio of time deposits to total deposits reduces this sensitivity. A higher ratio of non-interest income to total income also reduces this sensitivity, while capital-constrained banks have a higher sensitivity to monetary policy innovations. We argue that a higher dependence on non-interest income and the use of interest rate derivatives together may explain the disappearing influence of monetary policy on these BHCs.
