Both shaping and shaped by technological, economic and social facets, the world of work has witnessed a wide array of changes. This review article sets out to provide a synthesis of some of the main directions and insights of existing research connected to the new world of work. In particular, we approached the topic of new work practices through four key dimensions: (1) Conceptual and methodological dimensions in the study of new work practices; (2) Spatial and temporal manifestations of new work practices in the collaborative economy; (3) Individuals, organizations and new work configurations; (4) Power and control. The review article critically discusses the future of work and argues that the ‘new’ world of work simply repeats asymmetrical power relations and inequalities that characterise work activities, with the potential of exacerbating even further disparities, inequalities and precarity. 相似文献

We investigate the roots of scientists' perceptions of the impact of their work by examining stable psychological characteristics such as personality traits. An analysis of personality traits highlights the effects of policies related to gender equality, allocation of research time and skills acquisition. It improves our understanding of the conflicts related to scientists’ perceptions of the impact of their research on beneficiaries. For example, conscientiousness increases the perceived impact on clinical beneficiaries, but reduces the perceived impact on industrial beneficiaries. Organizational scientific freedom increases the effects of personality traits on perceived impact on beneficiaries such that scientists affiliated to a university are less likely than colleagues working in other research settings to perceive the simultaneous impact of their work on both industrial and clinical beneficiaries. 相似文献

Searching for Goldilocks: The Distance‐Based Capitalization Effects of Local Public Services 下载免费PDF全文
Trey Dronyk‐Trosper 《Real Estate Economics》2017,45(3):650-678
This article empirically models the effect of distance on residential property values of three different types of services, fire, police and emergency medical services. Interesting economic trade‐offs emerge as service station proximity provides both amenity and disamenity effects. Using over three million home sales from the state of Florida along with two different measures of distance, this study provides evidence of nonlinear capitalization effects on local housing values. A difference‐in‐difference model utilizing new facility construction provides corroborating evidence of these findings. 相似文献

The development of a fast and reliable Internet, new technologies online payment systems, and changes in work structure that enable and demand flexible working patterns have driven a move to a new form of Internet‐enabled labour exchange called crowdsourcing. Evidence from an in‐depth qualitative study is presented, focusing on selected users' interactions and experiences of working on two UK‐based crowdsourcing platforms. The paper shows that workers engaged in this form of labour exchange need to deploy existing employability skills and networks to effectively meet the challenges, and take advantage of the opportunities, that crowdsourcing presents. Individual factors and circumstances emerge as paramount for workers' continued engagement in this form of employment. Using selected components from an employability framework, the findings suggest that crowdsourcing can offer new pathways to practising skills and enhancing employability for some workers. 相似文献

This paper focuses on the organization of new product development in large, R&D‐intensive firms. In these firms, research and development activities are often separated. Research is conducted in dedicated research projects at specialized research labs. Once research results are achieved by research projects, they are transferred to business units for further development and commercialization. We investigate the speed whereby research projects transfer their first research results to business units (hereafter: transfer speed). In particular, we analyze the antecedents and performance implications of transfer speed. Based on data of 503 research projects from a European R&D intensive manufacturing firm, our results suggest that a fast transfer speed (as measured by the time it takes for a research project to develop and transfer its first research result to business units) is associated with a better research performance (as measured by the total number of transfers the research project generates). Moreover, we find that different types of external R&D partners—science‐based and market‐based partners—play distinct roles in speeding up project first research transfers. While market‐based partnerships (i.e., customers and suppliers) generally contribute to a faster transfer of first research results, science‐based partnerships (i.e., universities and research institutions) only speed up first research transfers of technologically very complex projects. Our results also show that early patent filings by research projects accelerate first research transfers. 相似文献

Firms developing new products often face the challenge of making investment decisions under uncertain input–cost conditions due to the price volatilities of the materials they use. These decisions need to be made long before the final products are launched on the market. Therefore, firms that invest in the opportunity to switch materials in a timely manner will have the flexibility to react to material price changes and realize competitive advantages. However, volatile material prices may also cause a firm to delay investment. Using real‐options reasoning, this paper studies the influence of input‐cost fluctuations on the timing decision to start new product development (NPD) and thus create the follow‐on opportunity to later replace an existing product. A model that combines waiting and switching options to derive influencing factors of the flexibility value that triggers the investment is developed and tested on a sample of material substitution projects from manufacturing firms. The results show how price uncertainty of the new and the old material, their joint price development, the expected project duration, and competitive preemption are related to the propensity to delay the start of NPD. The findings provide new insights on how timing in adopting materials can be used to hedge exposure to volatile material prices. The insights are relevant for adopters and producers of new materials, as well as for policy makers who strive for supporting the diffusion of new materials. 相似文献

Reducing tax system complexity is a common goal amongst policymakers; yet there is no commonly agreed definition of complexity. This paper seeks to fill this gap, by proposing the construction of an index of tax system complexity, conceived as a summary indicator of the overall complexity of a tax system at a particular point in time. If adopted, such an index would not only enable assessment of the changing level of a country's tax system complexity over time, but may also facilitate comparisons of the relative complexity of different countries' tax systems in future. 相似文献

This paper explores how informal information channels impact mutual fund performance. We measure the strengths of two location‐based information channels: 1) information transfers among fund managers (fund‐fund links) and 2) transfers between managers and the companies in which they invest (fund‐company links). We find that each channel increases investment performance in the absence of the other, but decreases it when acting in combination. Stock selection associated with the presence of one channel, but the absence of the other, earns positive future returns. Our results indicate that the economic benefits of informal information channels depend critically on the nature of their interactions. 相似文献

New Keynesian model in which households have Epstein–Zin preferences with time‐varying risk aversion and the central bank has a time‐varying inflation target can match the dynamics of nominal bond prices in the U.S. economy well. The model generates a large steady‐state term spread and its fitting errors for bond yields are comparable to those obtained from a nonstructural three‐factor model, and one‐third smaller than in models with a constant inflation target or risk aversion. Including data on interest rates has large effects on variance decompositions, making investment technology shocks much less important than found in other recent papers. 相似文献
