The impact of product diversification strategy on the corporate performance of large Spanish firms

We analyze the impact of product diversification on performance. This topic has been discussed in the literature, and there is no consensus so far as to the significance or the direction of the impact. Performance is measured using Tobin's q for a sample of 103 large, non-financial Spanish firms (1992–1995). Diversification is measured by means of a categorical variable, as suggested by Varadarajan. The principal results indicate that the firms with intermediate levels of product diversification have the highest performance, while the firms with low and high levels of diversification show significantly lower performance, which performance is not significantly different between them.     

An appropriate development strategy for Southern Africa∗

The limited successes achieved with development in the Third World and the national states in Southern Africa have necessitated a considerable change in development thinking and practice. The conventional developmental approach, which is based on growth models, is inappropriate for the conditions in the LDCs. A new development approach, coupled with an appropriate development strategy, has culminated in the development literature.

In this article the poverty problem in Southern Africa is outlined as a general background, whereafter the new development approach and a few guidelines for an appropriate development strategy is discussed. The application of the new strategy in the circumstances of Southern Africa is highlighted.     

Income and Price Elasticities of Demand in South Africa: An Application of the Linear Expenditure System

This paper investigates the expenditure patterns of South African households using detailed cross‐sectional expenditure and price data that varies across region and time. Linear expenditure system parameter estimates are used to calculate income and price elasticities for a number of product categories at different points of the income distribution. We find substantial variation in the price and income elasticities of demand for items across the income distribution, with the bottom quartile being extremely sensitive to increases in the price of food and clothing items, and the top quartile being as sensitive as households in developed countries.     

Tracking Can Be More Equitable Than Mixing

Parents and policy‐makers often wonder whether and how the choice of a tracked or mixed educational system affects the equality of opportunity. I answer this question by analyzing the influence of peers on future educational results. I define an equal opportunity policy as one that maximizes the average lifetime income of the worst‐off type of individuals in society (i.e., students from disadvantaged backgrounds). I find that tracking maximizes average lifetime income if the opportunity cost of college attendance is sufficiently high.     

Management Information System – A Tool for Corporate Sustainability

This paper represents the attempt to define a methodology that can evaluate the degree to which companies' information systems correspond to needs determined by the objectives of sustainability the firm imposes on itself. The result is the creation of a general model which define the correct approach to evaluating information systems – a model which should be adapted to the specificity of each single company which intends to adopt it. In the chart indicated, we obviously have not considered activities connected to the implementation of the survey system, which are particular to each company's situation. The first part of the paper consists of an overall introduction to the approach that has been used to assess the (MIS) of Granarolo, one of the Italian companies involved. The case study contains a profile of the company, the analysis of its MIS referred to the three dimensions of sustainability, and an evaluation of the strong points and issues to be developed. This approach to evaluate the gap between desired requirements of an information system for sustainability and current data available in a firm, has proved its consistency and usefulness. It helps to understand where data are, which dimensions, spheres, stakeholders account for and what is the level of integration between different information systems existing in the firm.     

Can incentives mitigate student overconfidence at grade forecasts?

Research shows that college students exhibit bias in their forecasts of exam performance. Most students are overconfident in their forecasts, academically weaker students are the most overconfident, and top-performing students are underconfident. The literature identifies negative repercussions of these biases, including inadequate preparation for exams. A recurring attribute of this literature is the absence of meaningful incentives for students to forecast accurately. We implement an extra credit scheme to incentivize accurate forecasts. Depending on how forecast bias is measured, the scheme mitigates bias by top-performing students and marginally mitigates bias by other students. Our results have several implications. First, we illustrate an extra credit tool instructors can use to incentivize students to make more thoughtful assessments of their future exam performance. Second, we show how the association between incentives and forecast bias differs across student groups. Finally, we show that results in this literature are sensitive to how bias is measured.     

Is the Unequal Treatment of Debtors in Natural Person Insolvency Law Justifiable?: A South African Exposition

The South African natural person insolvency system has remained largely creditor‐orientated and excludes many honest but unfortunate debtors from its ambit. This is despite the worldwide trend to accommodate all such debtors. Although the system does provide for three different statutory natural person debt relief procedures, the cumulative effect of these measures' entry requirements results in differentiation on financial grounds. This is as all statutory measures require the debtor to have some form of disposable assets or income available – thereby drawing a distinction between those debtors with and those without assets and or income (the so‐called no income no asset debtors). The main aim of this article is to measure the South African natural person insolvency system against the right to equality in terms of both the South African Constitution and the Promotion of Equality and Prevention of Unfair Discrimination Act. The article may benefit legislatures and policymakers in constitutional jurisdictions that subscribe to the equality principle and that directly or indirectly exclude some debtors from debt relief while providing others therewith.

South African Career Guidance Counsellors' and Mathematics Teachers' Perception of the Accounting Profession

The shortage of accounting professionals is well-documented. To address this shortage, greater numbers of school students should be attracted and enrolled in undergraduate accounting programmes. Unfortunately, school students may have misperceptions of the accounting profession. These misperceptions may result in potential entrants to the profession being lost to other professions. Secondary school teachers play an influential role in students' perceptions of future careers. This survey assessed the perceptions of the secondary school career guidance counsellors and mathematics teachers' perceptions of the accounting profession in South Africa in comparison to the medical, engineering and legal professions. The findings suggest that the accounting profession is held in lower esteem than the engineering and medical professions, but in higher esteem than the legal profession. The findings confirm previous research conducted in the USA, Australasia and Japan. Marketing and recruitment programmes should educate secondary school teachers as to the true nature of the accounting profession.     

Accounting students access to social media related resources and the risk of tacit social exclusion

ABSTRACT

The use of social media platforms to facilitate teaching and learning requires resources (hardware and Internet access) to enable active student participation. Limited access to these resources may impair students’ learning and, should the students consequently fail to graduate, tacitly contribute to their social exclusion. The results of a survey amongst students at a South African university, identified statistically significant differences relating to hardware and Internet access between more affluent students, and lower income students. Using social media may, therefore, be countering the objective of widening the admissions to universities in South Africa as an attempt to address past exclusionary practices. This study raises awareness with instructors and administrators globally, about the risk of tacit social exclusion, as a result of the tools selected to facilitate learning.
