Unemployment: an international perspective

Using standard OECD unemployment and national income account data, the rela-tionship between unemployment rates and the productivity-adjusted real wage rate is examined for six major countries, Australia, Canada, France, Germany, Japan, and the United Kingdom, using bivariate regression analysis. In addition, pooled cross-section estimates of the same relationship are provided for the 24 traditional OECD countries covering the period 1971-1995. The object is to determine whether the observed statistically significant positive relationship between these variables found for the United States exists in other economies. The basic conclusion is that the inter-national experience in this regard is similar to that for the United States. The research underlying the analysis reported in this article has been supported by the Joint Economic Committee of the Congress of the United States and is reflected in Vedder and Gallaway (1998).     

The safety costs of contingent work: Evidence from Minnesota

We find that workers’ compensation costs for leased/staff agency workers are about three times higher than for regular full-time workers. This differential grows even wider when controlling for worker characteristics. Authors give a number of reasons for this result, including claimsreporting moral hazard on the part of contingent work-ers. We also present results on claim denials by work status, which seems to support the cost model. The authors gratefully acknowledge research support from the grants for research program of International Foundation of Employee Benefit Plans (IFEBP). Comments from Rich Derrig, Larry Aarhus, members of the Industrial Relations Center workshop, and an anonymous referee are greatly appreciated. The authors also appreciate Brian Zaidman for his helpful comments and assistance with the data for this study.     

Families under the microscope: parallels between the young carers debate of the 1990s and the transformation of childhood in the late nineteenth century

Existing analysis and discussion about young carers—children caring for ill or disabled family members—has been limited in scope, concentrating on narrow policy and service issues. In this paper, I attempt to introduce a more historical perspective to these debates, by comparing responses to the issue of young caring in the 1990s to resistance encountered in the implementation of child labour and education reforms towards the end of the nineteenth century. I discuss the parallel ways in which the quality of childhood for some children became problematised without sufficient recognition of the limited choices that some families face.

An investigation on the effects of emerging 4G transmissions on 3G networks

Within the last 10 years, technological advances have allowed personal wireless communications to become part of our global, information-centric culture. Cellular telephones, personal digital assistants, and wireless computer networks allow for tetherless use anytime and almost anywhere. These wireless communication advances have quickly matured through three technological generations. Currently, wireless communications are considered to be in the third generation (3G) of deployment and are rapidly approaching the fourth (4G). As these wireless technologies advance to meet market demand, careful pre-market technical analysis of these new capabilities must be made to understand potential impact on existing communication systems. This paper provides a novel examination into the effects of 4G ultrawide band (UWB) signaling on a 3G wireless fidelity (WiFi) system. Through empirical and statistical analyses, we show that the throughput performance of the Wi-Fi system can be negatively impacted by up to 20%. We conclude that careful implementation of emerging 4G UWB systems must occur to mitigate the detriments to existing 3G communication systems.
