EVIDENCE ON RELATIONSHIPS AMONG ALTERNATIVE MEASURES OF CONCENTRATION: A TOOL FOR ANALYSIS OF LDC INEQUALITY

The evidence on economic inequality in nearly all developing countries is both seriously incomplete and of moderate to poor quality. In addition, information often corresponds to distributions which appear to be less revealing and useful than other ones; thus it can be argued that the frequently available distribution of income among households ranked by household income is less helpful than the seldom found distribution of consumption among persons ranked by per capita household consumption. Whether one's objective is to assess inequality in some absolute sense or (especially) to make comparisons across countries or evaluate trends over time, it is useful to know whether systematic relationships exist among various measures of inequality, in particular between those most commonly available and those conceptually most interesting. Illustrative comparisons of a variety of inequality indicators are presented. They suggest that in developing countries the concentration of income among persons (assuming equal distribution within the family) does not differ much from the concentration among households. They also suggest that the concentration of consumption is somewhat less unequal than that of income, the ratio of the respective Gini coefficients tending to cluster around 0.85 to 0.90.     

Integrating ecosystem services into conservation assessments: A review

A call has been made for conservation planners to include ecosystem services into their assessments of conservation priority areas. The need to develop an integrated approach to meeting different conservation objectives and a shift in focus towards human wellbeing are some of the motivations behind this call. There is currently no widely accepted approach to planning for ecosystem services. This study contributes towards the development of this approach through a review of conservation assessments and the extent to which they include ecosystem services. Of the 476 conservation assessments identified by a set of search terms on the Web of Science, 100 were randomly selected for this review. Of these only seven had included ecosystem services, while another 13 had referred to ecosystem services as a rationale for conservation without including them in the assessment. The majority of assessments were based on biodiversity pattern data while 19 used data on ecological processes. A total of 11 of these 19 assessments used processes, which could be linked to services. Ecosystem services have witnessed an increase in attention received in conservation assessments since the year 2000, however trends were not apparent beyond this date. In order to assess which types of ecosystem services and how they have been accounted for in conservation assessments, we extended our review to include an additional nine conservation assessments which included ecosystem services. The majority included cultural ecosystem services, followed by regulatory, provisioning and supporting services respectively. We conclude with an analysis of the constraints and opportunities for the integration of ecosystem services into conservation assessments and highlight the urgent need for an appropriate framework for planning for ecosystem services.     

Economies of scale in steam-electric power generation in East-North-Central U.S.

In this study the author investigates firm-level cross-sectional unit cost advantages for electricity generation for 31 regulated private steam-electric utilities in East-North-Central U.S. region during 1987. The production technology is modeled using the implied dual minimum total variable cost translog methodology. Estimates of Zellner’s Seemingly Unrelated Regressions indicate a smooth non-homothetic technology, a typical regional firm-level scale economies of about 0.263, and an implied mean cost-output elasticity of about 0.737. Significant scale economies exist for several of the smaller utilities. The findings support policies which steer energy-intensive industrial location decisions in a direction which captures unutilized unit cost economies in electricity generation.     

Alternative sources of technology: An analysis of induced innovations

This paper considers why firms differ in the degree to which they rely on their internal R&D organization for generating new technologies (induced innovations) rather than on existing external technology markets (purchased innovations). An empirical model is suggested to explan inter-firm differences in the percentage of new technology induced through R&D efforts. The analysis suggests that such differences are systematically related to the firm's size, its competative environment, and its degree of diversification.     

PDMA Success Measurement Project: Recommended Measures for Product Development Success and Failure

Success is not just elusive; it is also multifaceted and difficult to measure. A firm can assess the success or failure of a development project in any (or all) of many terms, including customer satisfaction, financial return, and technical advantage. To complicate matters, success may be measured not only at the level of the individual project, but also at the program level. With so many variables to consider and so many stakeholders involved, managers face a difficult challenge just deciding which measures are useful for measuring product development success. Recognizing that no single measure suffices for gauging the success of every product development project, Abbie Griffin and Albert L. Page hypothesize that the most appropriate set of measures for assessing project-level success depends on the project strategy. For example, the objectives (and thus, the success criteria) for a new product that creates an entirely new market will differ from those of a project that extends an existing product line. Similarly, they hypothesize that the appropriate measures of a product development program's overall success depend on the firm's innovation strategy. For example, a firm that values being first to market will measure success in different terms from those used by a firm that focuses on maintaining a secure market niche. To test these hypotheses, product development professionals were presented with six project strategy scenarios and four business strategy scenarios. For each project strategy scenario, participants were asked to select the four most useful measures of project success. For each business strategy scenario, participants were asked to choose the set of four measures that would provide the most useful overall assessment of product development success. The responses strongly support the idea that the most appropriate measures of project-level and program-level success depend on the firm's project strategy and business strategy, respectively. For example, customer satisfaction and customer acceptance were among the most useful customer-based measures of success for several project strategies, but market share was cited as the most useful customer-based measure for projects involving new-to-the-company products or line extensions. At the program level, firms with a business strategy that places little emphasis on innovation need to focus on measuring the efficiency of their product development program, while innovative firms need to assess the program's contribution to company growth.     

A Corporate Social Responsibility Framework for Accounting Research

Over the past two decades, there has been growing interest in corporate social responsibility (CSR) among accounting scholars. As a testament to this growing interest, two review papers on CSR were published last year in accounting journals. Implicitly guiding hypothesis development in CSR studies is the notion of a conflict between shareholders and stakeholders. We define CSR in terms of a win-win situation for shareholders and stakeholders: a CSR framework for strategic business purposes. We provide evidence supporting this outlook for CSR using cases pertaining to specific companies and findings from archival empirical studies. According to our CSR framework, resources allocated for CSR activity also help propel business strategy; as such, it is difficult to isolate CSR inputs and/or outputs due to problems of non-separability and multidimensionality. While measurement is a challenge, our framework nonetheless opens up various promising avenues for future research.     

Life Expectancy in 2040: What Do Clinical Experts Expect?

We use expert clinical and public health opinion to estimate likely changes in the prevention and treatment of important disease conditions and how they will affect future life expectancy. Focus groups were held including clinical and public health faculty with expertise in the six leading causes of death in the United States. Mortality rates and life tables for 2040 were derived by sex and age. Life expectancy at age 20 and 65 was compared to figures published by the Social Security Administration and to estimates from the Lee-Carter method. There was agreement among all three approaches that life expectancy at age 20 will increase by approximately one year per decade for females and males between now and 2040. According to the clinical experts, 70% of the improvement in life expectancy will occur in cardiovascular disease and cancer, while in the last 30 years most of the improvement has occurred in cardiovascular disease. Expert opinion suggests that most of the increase in life expectancy will be attributable to the already achieved reduction in smoking rates, especially for women.

Education and the empowerment of women in household decision‐making in Spain

It was analysed whether investment in the education of both women and men serves to empower wives resulting in more balanced household decisions being taken on matters related to consumption and financial management. They considered that household decision‐making could be made by mainly the wife, mainly the husband or the couple acting jointly. They then applied multinomial probit models to the Spanish Living Conditions Survey of 2010. Results show that, when controlling for demographic, family and labour market characteristics, the level of education of both the husband and wife has a positive effect in terms of a more egalitarian decision‐making process in relation to three areas of expenditure: daily shopping, expensive purchases of consumer durables and significant expenditure on children. However, only women's education has a positive effect on borrowing money and no effect of education is observed with regard to the use of savings. Results are less conclusive for households where decisions are taken primarily by the wife or husband, since men's education increases the role of husbands in the household making‐decision process whereas no effect of wives' education is observed.
