The Reallocation of Labour and the Lifecycle of Firms

This paper uses a unique US panel dataset of firms and workers toinvestigate the relationship between the firm's lifecycle and the reallocation of labour. We distinguish labour reallocation associated with job reallocation, and reallocation of workers over a fixed configuration of jobs. We find that firms at the beginning and end of their lifecycles contribute disproportionately to labour market lows, with sorting between firms particularly important among young firms, whereas sorting within firms is moreimportant among mature firms. We also find that high churning lows are associated with a lower probability of a young firm surviving.     

The Political Economy of Mobility Partnerships – Structural Power in the EU's External Migration Policy

The research on European Union (EU) external relations and the EU's own official discourse frequently portray the EU as a soft power that provides its neighbourhood with good governance principles. The European Mobility Partnerships (EU MPs) can be considered the most recent manifestation of this rhetoric. Studies on EU MPs reflect a narrow understanding of power. This paper aims to contribute to a more comprehensive understanding of the power dimension inherent in the EU's external relations. It develops a neogramscian theoretical framework to challenge the rhetoric of the EU as a soft power and normative hegemon. Drawing on semi-structured expert interviews and textual analysis of documents, it seeks to reveal whether and in what ways socio-economic power dynamics shape the EU MPs. This article argues that while, at the beginning, the design of the EU MPs as a policy tool has been very much influenced by neoliberal ideas such as the market-oriented liberalisation of mobility and the flexibilisation of labour, implementation is marked by the neo-mercantilist approach of restricting immigration and maximising the efficiency of readmission. Applying a critical political economy concept of power is helpful in understanding how market forces influence EU external migration policy, transcending a narrow understanding of power.     

Formal and Informal Practices of Knowledge Sharing Between Project Teams and Enacted Cultural Characteristics

This article investigates the process of knowledge sharing between project teams and uses a case study approach. This is especially relevant, as organizations face both the needs for separating work into projects and integrating knowledge created in projects into the organization. The results provided by the analysis technique of GABEK^® indicate that, although projects create boundaries, employees and project team leaders use formal mechanisms and develop informal practices for knowledge sharing between project teams. Furthermore, the article identifies organizational cultural characteristics enacted in these practices that can stimulate the discussion in “knowledge culture research” regarding the relationship of organizational cultural characteristics and (specific) knowledge processes.     

一种基于四相编码和优化阵列的MIMO STAP实现方法

多输入多输出（MIMO）雷达多信号间正交性和天线阵列结构影响空时自适应处理(STAP)性能。为了提高多信号间正交性,提出了基于遗传算法优化提高四相编码的自相关峰值并降低互相关峰值方法,保证了多发射信号间良好正交性,基本抑制了盲速影响。针对天线阵列稀疏导致盲速、阵元密布导致天线孔径过小的问题,基于最大连续孔径思想,提出了一种优化阵列结构,在不显著增加天线阵列长度和阵元数目条件下,与四相编码信号结合,实现了动目标检测。仿真实验证明,基于四相编码正交信号和收发阵列设计,MIMO STAP可实现良好动目标检测性能。     

Slotting Fees for Organic Retail Products: Evidence From a Survey of U.S. Food Retailers

Based on a survey of U.S. food retailers, our study finds that almost one third of U.S. food retailers charge slotting fees for certified organic food products, a retailing area where slotting fees had not previously been well documented. Econometric results from both ordered response and binary response models suggest that a number of firm-level attributes do influence the presence and/or relative size of organic slotting fees in a manner that is mostly consistent with an economic efficiency rationale and partly consistent with a market power/strategic behavior rationale for slotting fees.     

Book Reviews

While globalization has led to a well-documented increase in expatriation among managers and corporate executives, increased internationalization and expatriation have not been confined to business organizations alone. Educational institutions are becoming increasingly international with academics also experiencing growing levels of expatriation. However, despite their increasing international mobility, expatriate academics remain a group about which very little is known. Drawing on exploratory research carried out in Singapore and New Zealand, this essay presents several propositions about the experiences of expatriate academics as a hitherto under-researched group. In addition the essay moves towards adding another dimension to the existing expatriate management literature by considering the extent to which it can be used as a framework for understanding expatriate academics. In doing so the essay proposes some of the differences between expatriate academics and expatriate managers. The areas of focus are cross-culture training, expatriate adjustment and the expatriate family.     

Welfare-to-Work Outcomes: The Role of the Employer

This paper sets out to explore the role of the employer in successful welfare-to-work transitions. We demonstrate the uses of administrative records in identifying the types of firms that repeatedly hire welfare recipients. We also develop sets of criteria to identify “successful” outcomes. Our results suggest that there is substantial untapped potential for using administrative data to identify not simply which industries hire welfare recipients but those that are most likely to provide recipients with long-lasting jobs, or jobs accompanied by sustained removal from welfare dependency.
