Individual assessment involves one psychologist making an assessment of an individual for personnel-related purposes. Individual assessment practice is reviewed, and research on reliability is presented. A study examining the comparability of conclusions reached by consumers is presented. Eighty-six students and thirty-eight managers read nine narrative assessment reports (three of each of three job candidates) and attempted to determine which reports described the same candidate. None of the subjects could correctly group the nine reports; a sizeable proportion did no better than chance in grouping the reports. Implications for assessors and consumers of individual assessments are discussed.  相似文献

The debate concerning the emerging regulatory environment for employee voice continues apace, in particular the requirements to inform and consult employees as a result of the European Employee Information and Consultation Directive. This article examines the processes used to inform and consult employees across 15 case studies in the Republic of Ireland. It evaluates different voice arrangements using a conceptual framework that seeks to capture the dynamics of different employee voice schemes across union and non‐union companies. The findings suggest that participation is more robust when the channels for information and consultation accommodate both conflictual and cooperative processes. It is shown that robust forms of participation are more likely through processes that facilitate independent representation. The evidence also shows that some employers may devise their own counterbalancing forms of (pseudo) consultation, in an attempt to minimise the impact of regulatory rights for employee voice.  相似文献

We examine order type execution speed and costs for US equity traders. Marketable orders that execute slower exhibit lower execution costs. Those who remove liquidity faster and pay higher trading costs transact in smaller size, spread trading across more venues, take more liquidity, and are better informed. Nonmarketable limit orders that execute slower exhibit greater adverse selection; and larger, uninformed traders who concentrate their trading in fewer venues submit them. Our findings suggest that slowing down the trading process, when faster options exist, can benefit certain market participants who seek to cross the bid–ask spread.  相似文献

The Youth Training Scheme presented British unions with a mix of opportunities and threats. Patterns of interest in and policy towards YTS among the 42 largest unions are studied for 1983–8. Most unions showed interest in YTS but they divided sharply on whether or not to oppose it. Statistical analysis indicates a role for both economic and political factors in determining differences between unions in interest and policy. Opposition proved most intense and widespread among unions that represented the lower-grade occupations in the public sector. Such unions were heavily affected by trainee-employee substitution and in addition were relatively well placed to enforce its exclusion. Left-wing political orientation was also associated with opposition to YTS, but at the level of principle rather than action.  相似文献

Summary. A well-known result in the medical insurance literature is that zero co-insurance is never second-best for insurance contracts subject to moral hazard. We replace the usual expected utility assumption with a version of the rank-dependent utility (RDU) model that has greater experimental support. When consumers exhibit such preferences, we show that zero co-insurance may in fact be optimal, especially for low-risk consumers. Indeed, it is even possible that the first-best and second-best contracts are identical. In this case, there is no “market failure”, despite the informational asymmetry. We argue that these RDU results are in better accord with the empirical evidence from US health insurance markets.

Deploying a single nationwide broadband wireless network to serve all public safety users would have great advantages over the existing fragmented public safety systems. A nationwide system could be created to serve both public safety and commercial subscribers, which would allow a provider to exploit important economies but force it to meet the more costly requirements of public safety. This paper analyzes the viability of a public-private partnership that serves public safety and commercial subscribers from a for-profit provider's perspective. A model is presented that estimates the net present value (NPV) of a wireless network by calculating costs based on the number of cell sites required and revenue based on the projected number of subscribers acquired. The model is applied to both a network that serves only commercial subscribers on 10 MHz of 700 MHz spectrum and a public-private partnership that serves commercial subscribers and public safety personnel on 20 MHz of 700 MHz spectrum. It is found that NPV is greater for the public-private partnership than for the commercial-only network for any population density, which shows that the value of 10 MHz of spectrum exceeds the cost of meeting public safety requirements. Furthermore, the paper demonstrates that NPV/cell increases with population density, so urban areas are profitable and rural areas are unprofitable. The paper demonstrates that a partnership covering 94% of the US population breaks even because the most urban 56% of population subsidizes coverage for the next 38%. If initial deployment is subsidized, a financially sustainable public-private partnership can serve much more than 94%. Additionally, it is shown that allowing urban municipalities to opt-out of the partnership can significantly increase the subsidies required.  相似文献

How much economic value did broadband Internet create? Despite the importance of this question for national policy, no research has estimated broadband's incremental contribution to U.S. GDP by calibrating against historical adoption and incorporating counterfactuals. This study provides benchmark estimates for 1999 through 2006 and finds that broadband accounts for $28 billion of the $39 billion observed in 2006. Depending on the estimate, households generated $20-$22 billion of broadband revenue and approximately $8.3-$10.6 billion was additional revenue created between 1999 and 2006. Consumer surplus accounted for $4.8-$6.7 billion of this amount, which is not measured in GDP. An Internet-access Consumer Price Index would have to decline by 1.6-2.2% per year for it to reflect this unmeasured value. These estimates differ from existing benchmarks by an order of magnitude and relate to several policy debates.  相似文献
