We consider whether disaggregated data enhance the efficiency of aggregate employment forecasts. We find that incorporating spatial interaction into a disaggregated forecasting model lowers the out-of-sample mean squared error from a univariate aggregate model by 70% at a two-year horizon.  相似文献

This paper is a synthesis of the July 2005 Development Report published by the Development Bank of Southern Africa, Human Sciences Research Council and United Nations Development Programme (DBSA, HSRC and UNDP). The Report asks why, if the origins of economic dualism are rooted in the cheap, forced, migrant labour introduced by the mining industry and reinforced during apartheid, does dualism persist under democracy when all the relevant laws and many of the practices of the past have been abolished? The breakdown of apartheid did not immediately translate into improved material conditions for the majority of South Africans: 300 years of colonialism and 50 of internal colonialism had hard-wired a duality into the system. Two worlds, which may be conceptualised as the first and second economies, coexisted: a globally integrated world of production, exchange and consumption, and a constrained world of informality, poverty and marginalisation. This synthesis sheds light on the origin and nature of the ‘second economy’ metaphor, and suggests solutions.  相似文献

While most prior research suggests that the average change in market value of acquiring firms varies closely around zero, recent research grounded in the resource‐based view and organizational learning theory identify positive returns to acquirers. We contribute to this literature by focusing on acquisitions of Internet firms and the potential for the transfer of scarce resources. We hypothesize that acquisitions made by offline firms of Internet firms and by Internet firms of other Internet firms lead to positive market valuation for the acquirer. Results of an event study of 798 acquisitions of Internet firms provided support for these predictions. We also find that prior alliances with online firms do not reduce the gains from such acquisitions to offline firms. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

This article explains how to obtain straightforward extensions of the most popular univariate non‐nested statistics, and of the RESET‐test, to a multivariate context and examines how to use these tests to compare alternative factor demand systems. The empirical application involves the classical Berndt–Khaled KLEM data set. A statistically adequate specification is determined for each competing factor demand system. The empirical results are interpreted for each system, the models are compared on the basis of multivariate paired and joint non‐nested procedures and practical indications about what to expect if these tests are applied to alternative factor demand specifications are provided.  相似文献

In this note we reconsider the paper of Zhang and Zhang (1997), published in Managerial and Decision Economics, who analyze a strategic delegation model with R&D spillovers in an imperfectly competitive market. We were motivated to study their setup by a puzzling result given in their paper: delegating the production and R&D decisions to managers is never beneficial for the owners of the firm. When we tried to understand the driving forces of this result, we found however that the findings of Zhang and Zhang (1997) are incorrect. We explain why their derivations are wrong and demonstrate via counterexamples that the main propositions in their paper do not hold. In addition, we show how the correct solution of this R&D model with spillovers can be obtained. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

Although increasing numbers of graduates now enter the UK labour market, there has been little evaluation of the benefits that this component of the workforce is reported to bring to employing organisations. This study focused on nursing; a profession in which graduate entry is increasing but potential benefits of moving to all‐graduate entry are strongly contested. Career behaviour and expectations of graduate nurses were compared with those of diploma‐qualified nurses. Career behaviours were similar but differences were found in fulfilment of expectations that reflected findings reported for graduates in other employment contexts. Graduates entered nursing with higher expectations than diplomates but these were often unfulfilled. Graduates reported lower levels of satisfaction than diplomates over time and became less likely to intend remaining in nursing. Implications for increasing graduate entry are discussed, together with strategies to facilitate better synchronisation between graduate expectations and opportunities within the NHS and beyond.  相似文献

TESTING POVERTY LINES   总被引:1,自引:0,他引:1  
In theory, a poverty line can be defined as the cost of a common (inter‐personally comparable) utility level across a population. But how can one know if this holds in practice? For groups sharing common consumption needs but facing different prices, the theory of revealed preference can be used to derive testable implications of utility consistency knowing only the “poverty bundles” and their prices. Heterogeneity in needs calls for extra information. We argue that subjective welfare data offer a credible means of testing utility consistency across different needs groups. A case study of Russia's official poverty lines shows how revealed preference tests can be used in conjunction with qualitative information on needs heterogeneity. The results lead us to question the utility consistency of Russia's official poverty lines.  相似文献

This paper uses a case study approach to analyze the turnaround actions of two restaurant firms and compares them to the model of Robbins and Pearce [1992. Strategic Management Journal 9, 287–309]. The objective of this study is to scrutinize why these firms were unsuccessful in turning around and identify gaps between the firms’ actions and the empirical model of turnaround proposed by Robbins and Pearce. Two key turnaround measures, i.e., retrenchment and recovery are explored in detail and discussed in the context of the firms. The need for studying turnaround strategies is warranted as the number of hospitality firms that perish because of unsuccessful turnaround strategies is on the increase. Since turnaround strategies have not been pursued vigorously as a stream of research within the hospitality industry context, this approach would provide a framework for hospitality researchers to initiate similar future research efforts, which in turn would help the industry cope with turnaround.  相似文献
