In this study both aggregate and industry‐level foreign direct investment (FDI) data are employed to investigate the spatial dependence of FDI hosts. The analysis contributes to the existing literature by focusing on the heterogeneous spatial correlation of FDI in different industries. Using more comprehensive FDI data across multiple industries and multiple provinces in China from 1999 to 2007, the results show a significant spatial correlation among provinces. Aggregate FDI tends to be regional trade platform oriented indicating neighboring provinces become competitors for FDI. In contrast, results based on industry‐level provincial FDI show stronger support for vertical or complex vertical FDI.  相似文献

We present a theoretical analysis of different types of active labor market policies in the context of a search-matching model. We find that labor market training is effective in bringing down unemployment while public employment services and subsidized jobs are not effective at all. This theoretical finding is confirmed in an explorative empirical analysis using data from 20 OECD countries.  相似文献

Strategic flexibility is a vital capability for new ventures to update their strategies in a timely manner. However, the role of external knowledge sources in new ventures’ endeavours to develop strategic flexibility are unclear. Drawing on the knowledge‐based and relational views, we explore the effect of two sources of external knowledge: new product development (NPD) alliances, representing tightly coupled sources, and loosely coupled sources such as industry associations. Our field study of 148 high‐tech ventures found that the extent to which firms utilize knowledge from NPD alliances has a curvilinear relationship with strategic flexibility, whereas the extent to which firms utilize loosely coupled sources has a positive linear relationship with strategic flexibility. We also found that in new ventures, decentralization of decision‐making and institutional support enhance knowledge integration, positively moderating these relationships.  相似文献

What drove the precocious industrialisation in Britain was not demand for machines but rather (as Joel Mokyr and his co-authors have argued) the supply of useful knowledge and the skills needed to put it into practice. They were the force behind early innovation. But they did not act alone. They were reinforced by British institutions, which gave the British economy a century's head start over the rest of Europe and likely too over the rich parts of Asia. The institutions included a uniform fiscal and legal system; an effective means of training apprentices, who had escaped from local guild control; and a parliament that could raise taxes and exercise eminent domain but was at the same time a credible protector of private property. Among other things, these institutions facilitated the transportation of goods such as coal and they were backed up by policies that worked in favour of manufacturing. Together, the institutions and policies generated agglomeration effects that encouraged innovation. The agglomeration effects were more pronounced in western Europe than anywhere else in Eurasia and more developed in Britain than anywhere else.  相似文献

In this paper we observe that firm size (SZ) and book-to-market (BM) cannot fully explain stock returns on prior-return- (PR-) based portfolios in the Japanese stock market. The overreaction effect after controlling for the SZ and BM effects is significant and persistent, and accounts for a large part of the zero-investment returns on the loser to the winner. We therefore propose a new mimicking portfolio whose returns mimic the common factor in returns related to overreaction. Our evidence shows that the proposed four-factor model captures common variation in returns on portfolios, based on stocks SZ, BM, and PR, better than the well-known three-factor model does.  相似文献

Abstract

Organizational justice research tends to focus on the effects of fair treatment from organizations or supervisors on employee attitudes and behaviors. Thus, there is a dearth of research on the effects of fair treatment attributable to other parties that employees interact with at work such as coworkers and clients. Controlling for organization-focused and supervisor-focused justice, results from our field study of employees working in a healthcare organization demonstrate that perceptions of client-focused fairness uniquely predicts supervisor ratings of employees organizational citizenship behavior toward clients and that perceptions of workgroup-focused justice uniquely predicts organizational citizenship behavior toward workgroups. Further, we find that client-focused justice perceptions uniquely predict employee turnover intention.  相似文献

We describe a common pool resource game in which players choose how much of the stock to extract in a sequential manner. There are two choices and one represents taking a larger proportion of the stock than the other. After a player makes a choice, the remaining stock grows at a constant rate. We consider a game with a finite number of alternating moves. It is shown that changes in the larger proportion of the stock that the players are allowed to take and the growth rate affect equilibrium, but have little effect on behavior in the laboratory. In addition to observing more cooperation than predicted, we observe that parameters that are strategically irrelevant affect behavior. The results of this research might help policy makers in developing adequate policies to prevent overexploitation of some natural renewable resources.  相似文献
