The need for more appropriate forms of urban management: The case of land use controls and home businesses

The problems which confront urban management in South Africa are likely to change significantly in the near future, as we are faced with cities here which compare far more closely to Third World cities elsewhere. This article focuses on one aspect of urban management, that of land use control and the management of home businesses, to demonstrate the nature of the problems emerging in our cities and the demands which these will place on the urban administrative systems. Drawing on a survey of home businesses in six residential areas in Cape Town, the article argues that present systems of land use control have broken down in both wealthier and poorer areas. However, the widespread (and unexpected) support for home businesses in these areas suggests that a more flexible approach to land use control, and a higher degree of use mix, will gain public acceptance. Some basic principles are put forward to inform a different approach to land use control.     

An additional approach for interpretation of multiple discriminant analysis in business research

Several useful approaches for interpreting multiple discriminant analysis (MDA), including graph plots, have recently been illustrated for business researchers. This article proposes and illustrates an extension of the traditional plotting procedures in MDA that allows the depiction of both group overlaps and differences among groups. We also discuss several other interpretational approaches in MDA.     

Kalman filtering as an alternative to Ordinary Least Squares — Some theoretical considerations and empirical results

The purpose of this paper is to highlight the superiority of the Kalman filter over Ordinary Least Squares for estimating the unknown coefficients of the classical linear regression model. Both methods are analyzed with respect to their optimality properties and their usefulness in dealing with multicollinearity. Theoretical results are applied to two economic models.     

Corruption and change: the impact of foreign direct investment

This study examines influences on the level of corruption in countries from a strategic perspective. Corruption is one of the country‐level influences on market entry, investment, and other decisions fundamental to strategic management at the international level. The study examines the impact on corruption of change in levels of foreign direct investment (FDI). It uses the Corruption Perceptions Index (CPI) scores computed by Transparency International for 1999 and 2000. Results indicate that the more rapid the rate of change in FDI, the higher the level of corruption. Higher levels of perceived corruption are associated with each of two dimensions of national culture: uncertainty avoidance and masculinity. Research and managerial implications are also discussed.

Agriculture looks for ‘shoes that fit’: The production responsibility system and its implications

by the end of 1981 problems clearly recognized within the communes included low productivity, the failure to accumulate funds for modern inputs, inefficient and corrupt cadres, hidden unemployment, inability to stimulate growth in other than major crops and disappointingly low levels of peasant incomes in many counties. In north China, peasants in 1980 began to divide up the collective fields on communes into smaller plots for cultivation by households and labour groups. Since then the face of China has been altered — physically, politically and organizationally — by the creation of the ‘responsibility system’ largely outside party control and influence. ‘Document 75’ of September 1980 sanctioning some form of ‘production responsibility system’ was itself overtaken by events, as a bewildering variety of forms emerged, swamping the cadres. Practice was rapidly expanding beyond the theoretical discussions, or pronouncements of officials like Du Runsheng The paper describes each of the many forms of contracting between peasant groups and the State now current in China, with estimates of the relative proportions of the accounting units involved in each type (Table 3). New contradictions are already emerging in the changed rural set-up, partly because farm management problems bear similarities to those that confronted the open-field strip farming of the European Manor, while the incentive to have more hands on family farms contradicts official Chinese population policy.     

Are there economies of scale in the demand for money by firms? Some panel data estimates

We estimate elasticities of scale in the demand for money by firms using firm level panel data from Spain, the UK, and the US. This elasticity is one for Spain and the UK but smaller for the US. We find that the errors in the money demand equations contain two terms that are correlated with sales. Firstly, a permanent firm effect that captures differences in technological sophistication. Secondly, a measurement error in sales, which becomes relevant when relying on changes in sales to account for fixed effects. Failure to control for these correlated unobservable terms results in important biases in the estimated sales elasticities.     

Managing disabilities in an integrated health environment: the experience of Aetna

Disability-related outlays are increasing at a rate well above the medical inflation rate. This article discusses the experience of one company in its attempt to manage these skyrocketing costs, by developing a new program that integrates health and related benefits by combining the medical and human resources interventions into a unified program. The authors discuss the initiation, development and progress of the program, concluding with measured results revealing reduced lost work time, improved employee health and productivity, and reduced disability costs.
