This paper addresses the issue of measuring armed forces’ performance in crisis response operations. By means of interviews (17 respondents) and a large scale survey (1,253 respondents) field and general officers of the Netherlands Armed Forces (NAF) have been questioned on perceived organisational success in crisis response operations. The Dutch officers assess the NAF's performance positively. A number of senior officers are hesitant about the usefulness of measuring the performance of crisis response operations. According to them the context in which the operations are being executed is too complex. Most interviewees, however, are convinced that measuring performance is useful and should be improved. These military leaders express a strong need for criteria to assess their performance on the job.  相似文献

We examine the role of school grades as a signal of worker productivity under different examination systems in relation to errors that may affect student performance. Firms use school grades as a signal of workers’ effective skills, taking into account that these evaluations are effected by stochastic shocks. We show that more precise evaluation systems, being associated with a higher reactivity of wages to school grades, induce students to provide more effort. Low ability students tend to react less than high ability students. Moreover, individuals with low abilities may prefer less accurate evaluation systems. Nevertheless, when productivity increases, these systems become less convenient and the number of individuals preferring them diminishes. Our analysis highlights an important trade-off between centralised and decentralised evaluation systems. On the one hand, frequent evaluations, typical of decentralised systems, weaken the impact on grades of those errors which influence student performance and, so, reduce signal noise, while, on the other hand, different teachers generally adopt different performance assessment standards, leading to noisier evaluations.  相似文献

The paper analyzes how countries use competition policy as a tool for strategic trade. In the model, two countries export to a third country. Each exporting country is endowed with a set of differentiated products. Each government chooses the number of exporters for its country and the products that each exporter sells in the first period, and a tax policy in the second period. Firms choose prices or quantities independently in the third period. In the unique subgame‐perfect equilibrium, both countries group all their products within a single firm—the “national champion policy.” We study the implication of different assumptions about the timing of the game.  相似文献

This article appraises the recent UK quantitative easing (QE) monetary experiment. From March 2009 to February 2010, the Bank of England spent £200 billion on gilts and corporate bonds. This experiment represents, as a proportion of GDP, the most ambitious monetary policy ‘mission’ in history. Using several indicators to examine the impact of QE, our analysis leads to a conclusion which, metaphorically, is akin to that ascribed to the 1970 Apollo 13 Moon mission: a ‘successful failure’.  相似文献

In this introduction to our special issue, we will first seek to discuss the extent to which recent expatriation research and literature is still subject to earlier criticisms. Second, we will discuss the future research needs concerning the theme of this special issue, international careers, briefly reviewing the dominating research theme within the international career context (i.e., the career impacts of international assignment) and suggesting some future research areas. After that, we will offer a particularly promising new avenue for future research: the new forms of international work. We will conclude by summarizing the articles for this special issue and illustrate how they fit within this new avenue. © 2010 Wiley Periodicals, Inc.  相似文献

Varying institutional environments provide the foundation for a great deal of international business (IB) research yet relatively little empirical work has examined the association between institutional factors and new business development in emerging economies, although the importance of new business development for economic transition and growth is widely acknowledged. Drawing from social network and institutional theories, we address this gap by examining the effect of associational activity on the level of new business activity in emerging economies, and testing the thesis that associational activity becomes more instrumental for new business creation when aspiring entrepreneurs confront higher institutional burdens (i.e., obstacles derived from underdeveloped or absent institutions). On the basis of data from two cross-national research projects—the Global Entrepreneurship Monitor and the World Values Survey—we find a positive relationship between a country's associational activity and new business activity; this relationship is stronger for higher regulatory and normative institutional burdens and lower cognitive institutional burdens. This study is among the first to examine empirically the possible substitution effect between social ties and institutions to predict new business activity; it paints a nuanced picture of how social networks might be more instrumental in contexts characterized by weak institutions. We discuss the implications of these findings for IB theory and practice and offer directions for further research in the area.  相似文献
