Environmental quality indicators: Background,principles and examples from Norway

The need for a simple and general overview of the development in the state of the environment has led to work on environmental indicators in several countries and international organizations. Except for the basic common requirement of providing an overview, the works vary a great deal with regard to final aim, target groups, classification and, hence, choice of indicators. This paper gives an overview of the work carried out in the Central Bureau of Statistics of Norway within this field, with emphasis on the basic principles behind the choice of indicators. A hierarchical system of indicator sets is proposed, and examples of indicators are presented. Also, a brief overview of work carried out elsewhere is included.     

Stability and agreement criteria for the termination of Delphi studies

This paper addresses the question of the methodology of testing for stability between successive Delphi rounds and the necessity of doing so prior to the analysis of the level or type of consensus. Following a discussion of a hierarchical set of a criteria for determining the termination of such studies, the paper reviews some of the more common treatments of the subject in the literature. It is finally proposed that a χ² test be used to test the stability of responses between rounds. The method is demonstrated by a numerical example.     

A brief study of age specific birth proportions,Japan and Singapore

The suitability of age-specific birth proportions (ASBP), or percentage distribution of births, as a rough and ready index of fertility change was analyzed by establishing a theoretical framework for its limitations and uses. The discussion suggested that the utility of ASBP as an indicator of fertility change depends on the characteristics and behavior of the population being considered. The concept was then empirically applied to birth trends in Japan and Singapore for 2 different time periods. Analysis suggested that ASBP trends in Japan reflected changes in age-specific fertility rates relative to general fertility rate as well as trends in parity distribution. The Singapore analysis was more complicated, raising different issues. As very limited empirical work has been done on ASBPs, the utility of ASBPs as an indicator of fertility change cannot be definitely ascertained. It was suggested however that ASBP trends may be applicable in countries where the age distribution of fertile-aged women is fairly stable. More empirical research should be done on ASBP trends in other countries, the behavior of A matrix as discussed in this paper, and useful empirical relationship of ASBP with other fertility measures.     

Developing holistic leaders: Four domains for leadership development and practice

Leadership development and practice have traditionally been quite narrow, with a decided focus on the analytical realm of leadership. However, the contemporary climate of corporate scandal and resultant loss of societal confidence, coupled with the evolving demands, needs, and expectations of employees, point to the potential need for a more holistic approach to leadership. Thus, this article proposes how management education and leadership development programs can develop holistic leaders that are adept at operating in the analytical, conceptual, emotional, and spiritual domains of leadership practice. An integrated model for holistic leadership development and practice that addresses all four of these domains is proposed, and grounded in both established and emerging leadership development theory. Additionally, a leadership development classification scheme is proposed based on classroom, job, and organizational contexts.     

Late entry,market shares and competitive survival: The case of synthetic fibers

This paper examines product policy in relation to the experience curve and product life cycle concepts in the context of the experience of the thirteen major firms in the Western European synthetic fibers industry. It examines the hypothesis based on Boston Consulting Group and the Profit Impact of Market Share (PIMS) evidence that late entrants to a market will be at a competitive disadvantage because they lack the accumulated experience of the pioneering firms. For each of the three main synthetic fibres, acrylic, nylon and polyester, it was found that the early entrants who established major market shares early in the growth phase of the product life cycle were able to maintain that leadership nearly twenty years later. In contrast not only did almost all the late entrants fail to achieve significant market shares but in the difficult market conditions between 1974 and 1981 they provided seven out of nine market withdrawals.     

A note on the extension of tables for the Friedman statistic

Abstract  The tables for the Friedman rank-test arc extended using a sampling method. A table is given for the traditional significance levels .01, .025, .05 and .10 for number of blocks equal to 7 and 8 and for treatments of size 6 and 7. A brief discussion of available tables is also included along with an example of an application.     

The First U.S. Food Stamp Program: An Example of Rent Seeking and Avoiding

Abstract . Rent seeking involves the wasteful expenses incurred to secure, acquire, or maintain a monopoly position. Rent avoiding involves the expenditures undertaken to avoid the imposition of rent-seeking costs. Each represents a social cost of Tullock rectangle loss in addition to the dead-weight or Harberger triangle loss that combined to form the Harberger-Tullock trapezoid social cost. The first Food Stamp Program in the United States came about through the rent-seeking and/or rent-avoiding efforts of farmers, grocers, bankers, and other economic agents and did not lead to the promotion of social welfare. The evidence of these self-interested efforts was gleaned from articles in the New York Times and government documents. The first Food Stamp Program also fits the economic theory of regulation developed by Stigler, Jordan, Peltzman and others, and it involved imposed costs on economic agents as the program evolved.     

Bank lending rules for managing sovereign risk

A simple domestic lending rule is one that ensures that the loan rate exceeds the bank's cost of capital and the borrower's expected cashflows exceed the terminal value of the loan. Because a sovereign loan is not collateralized and lacks recourse, the domestic lending rule is not adequate for making sovereign lending decisions. Three modifications are suggested. First, the sovereign borrower's time preference for consumption needs to be considered. Second, the domestic borrower's decision to default voluntarily is made after observing the value of the collateral whereas the sovereign borrower's decision is made after observing earnings. In this paper, the sovereign borrower upgrades expectations in a Bayesian manner. Although no lending rule will completely prevent a default, the probability of default can be managed leading to a third modification.     

Strengthening executive decision making

Although decisions determine corporate fates, executives don't always know how to make the best choices. The author examines today's dissatisfaction with corporate decision making, reviews how it can deteriorate as the pace of change increases, and offers five comprehensive strategies for improving the decision making process. © 1995 by John Wiley & Sons, Inc.
