Workforce drug testing: a critique and reframing

This article aims to stimulate re‐engagement with workforce drug testing as a current managerial technology emerging in UK organisations and not solely confined to the US. Drawing on sociological, labour process and wider organization studies literature, it reconceptualises assumptions about managerial ideology, employee agency and drug user's subjectivity.     

The Revenue–Expenditure Nexus: The Experience of 13 African Countries

Abstract: The aim of this paper is to investigate the causal relationship between government revenue and government expenditure for 13 African countries within a multivariate framework using a modified version of the Granger causality test due to Toda and Yamamoto (1995) . The empirical evidence suggests that there was a bi‐directional causality running between expenditure and revenue for Mauritius, Swaziland and Zimbabwe; no causality in any direction for Botswana, Burundi and Rwanda; unidirectional causality running from revenue to expenditure for Ethiopia, Ghana, Kenya, Nigeria, Mali and Zambia; and a uni‐directional causality running from expenditure to revenue for Burkina Faso only.

Exporting and Economic Performance: Firm‐level Evidence of Spanish Manufacturing

In a previous paper, Delgado, Fariñas and Ruano (2002) report TFP differences between exporters and non‐exporters on the basis of a sample of Spanish manufacturing firms. In this paper, we extend the previous analysis in three directions using a similar data set. First, we investigate additional economic performance differences between exporters and non‐exporters. Second, we measure TFP differences estimating production functions that control for unobserved heterogeneity and simultaneity bias. Third, we explore the self‐selection and learning‐by‐exporting hypothesis as explanations for the greater performance of exporters. With respect to the results, we confirm that many indicators of economic performance such as productivity, size, wages and innovation are greater in exporting firms. Furthermore, TFP differences between exporters and non‐exporters estimated with parametric methods are remarkably similar to those estimated using index numbers. Finally, performance differences and transition patterns between the export market and the domestic market indicate higher performance for entering exporters with respect to non‐exporters at the moment of entry. We find evidence of selection in the entry and the exit side of the export market. One of the basic results that we obtain indicates that after controlling for self‐selection, the productivity growth of entering exporters does not significantly change with respect to non‐exporters. As the evidence we find indicates no systematic changes in performance between non‐exporters and exporters after entry takes place, we do not confirm the learning‐by‐exporting hypothesis.     

解决农业县财政贫困是构建和谐社会政府间财政关系的核心

一、理顺政府间财政关系的两个理论支点政府间财政关系是指以财政体制和财政转移支付制为基础的多级政府的理财关系。我国宪法规定了五级政府制和分级管理原则,因此,上级政府对下级既是包含关系,又是自主理财关系。这种既包含,又自主的两者关系,是现阶段政府间财政关系的基本矛盾。     

Argentina: Macroeconomic Crisis and Household Vulnerability*

Using panel data from the Argentine Permanent Household Survey, this paper analyzes which households were more vulnerable to the Argentine macroeconomic crisis during 1999–2002. Results suggest that the impact of the crisis was not uniform across households, which differed in their ability to cope with shocks. In particular, households with more children, and whose head was male, less educated, and employed in the private sector were the most vulnerable, suffering larger than average declines in income. Shocks to labor income were significant, with both unemployment rates and unemployment spells increasing throughout the period, particularly during the peak of the crisis towards the end of 2001. Individuals with low levels of human capital (proxied by education and experience), males, and self‐employed were more likely to lose their jobs. Public sector employees, in contrast, were more protected from the impact of the crisis on employment.     

Restructuring the electricity distribution sector: Implications for local government

This article discusses the proposals for restructuring the South African electricity distribution sector, with specific reference to the impact that such restructuring may have on local government. Currently, local government distributors rely on revenue from electricity sales to generate a surplus that is channelled into the relief of rates and provision of other services. The removal of this source of revenue may further impede the efficacy of local government. Issues pertaining to accountability, tax incidence and the financial viability of municipalities will also be affected, and therefore require further thought and clarification before a policy process is set in motion which yields adverse consequences.     

African elephants: the effect of property rights and political stability

African elephant populations have declined by more than 50% over the past 20 years. International outrage over the slaughter led to a worldwide ban on ivory sales beginning in 1989, despite the objections of many economists and scientists, and of several southern African countries that have established systems of property rights over elephants. Far from declining, elephant populations in many of these countries have increased to levels at or above the carrying capacity of the ecosystem. This article estimates the determinants of changes in elephant populations in 35 African countries over several time periods. The authors find that, controlling for other factors, countries with property rights systems of community wildlife programs have more rapid elephant population growth rates than do those countries that do not. Political instability and the absence of representative governments significantly lower elephant growth rates.     

The processes of defining corporate responsibility: a study of Swedish garment retailers' responsibility

Despite extensive research on corporate responsibility, little research exists on how the inter‐organizational processes of defining corporate responsibility develop. In this paper, we present a framework based on actor‐network theory (ANT) for analysing these processes. The developed framework is illustrated in a study of the redefinition of Swedish garment retailers' responsibilities for workers' rights at suppliers' factories between 1996 and 2004. We show that definition processes can be characterized as battles for the right to interpretation, and that traditionally non‐dominant actors can, at least temporarily, win these battles and dictate the development of the processes for defining corporate responsibility. We also show that definition processes can take an exclusionary form prohibiting certain actors from participating. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.     

INTERORGANIZATIONAL TIME‐BASED POSTPONEMENT IN THE SUPPLY CHAIN

This paper presents the results of empirical research on the use of time‐based postponement in a supply chain context using data collected from two manufacturers, a distributor, and a retailer. The analysis shows that implementing postponement at the firm level can result in the supply chain carrying more inventory. In order to achieve its full potential, postponement needs to be implemented across organizations in the supply chain.
