Research and Technology Outsourcing   总被引:5,自引:0,他引:5  
The paper discusses the process of externalization and the contracting out of R&D and technical activity. The focus of the analysis is on the outsourcing of R&D and technical activity undertaken by firms and now outsourced to companies and organizations which supply the Contract Research and Technology (CRT) market. The analysis highlights that not only is it important to understand the factors in the demand for such services but also in changing dynamics of the nature of the research and technical services supplied and the way they are supplied. The paper then investigates the implications of these dynamic trends for the conduct of the R&D function, particularly towards research externalization and outsourcing, via the use of firms and organizations involved in contract research and technology.  相似文献

Private charities often publicise generous individual contributions or contributors, possibly to encourage others to give. In contrast, public good experiments used to study voluntary giving commonly tell participants only of total contributions. This paper reports an experimental test of the effect on contributions of supplying additional selective information. A control treatment is run that reveals only total contributions over ten one‐shot decision rounds. This is compared to a second treatment that also informs subjects of the maximum contribution made in their group after each round. In a third treatment, subjects are further given the opportunity to make costly rewards to the maximum contributor. Revealing generous contributions appears to raise average contributions slightly. Surprisingly, adding the ability to reward large contributors does little to generate further increases, though it significantly raises the variance of contributions.

We show how to nonparametrically identify the distribution of unobservables, such as random coefficients, that characterizes the heterogeneity among consumers in multinomial choice models. We provide general identification conditions for a class of nonlinear models and then verify these conditions using the primitives of the multinomial choice model. We require that the distribution of unobservables lie in the class of all distributions with finite support, which under our most general assumptions, resembles a product space where some of the product members are function spaces. We show how identification leads to the consistency of a nonparametric estimator.  相似文献

Understanding the effects of historical circumstance on contemporary development patterns is important in understanding the overall trajectories of societies. Using a spatially centered technique and various sources of historical and contemporary data, this link is tested by examining variations in historical levels of conservative values in the American South on contemporary patterns of development. This context provides an interesting case study involving a time and region marked by rapid social change. Results show that the spatial distribution of development levels is non-random and that historical levels of highly conservative values are associated with lower levels of contemporary development.  相似文献

Control rights, pyramids, and the measurement of ownership concentration   总被引:1,自引:0,他引:1  
The recent corporate governance literature has emphasised the distinction between control and cash-flow rights but has disregarded measurement issues. Control rights may be measured by immediate shareholder votes, the voting rights as traced through ownership chains, or voting power indices that may or may not trace ownership through chains. We compare the ability of various measures to identify the effects of ownership concentration on share valuation using a German panel data set. The widely used weakest-link principle does not perform well in this comparison. Furthermore, measures that trace control through ownership chains do not outperform those that rely on immediate ownership, thus questioning the role of pyramids in the separation of control and cash-flow rights. The paper emphasises that there is a distinction between these two aspects of ownership even without pyramids or preferred stock, identification of which requires measures that, like the Shapley–Shubik index, do not simply equate control rights with voting rights.  相似文献

Two approaches taken to the embodiment question are compared and discussed: quantitative theory and traditional growth accounting. The two approaches give very different estimates for the contribution of investment-specific technological advance to economic growth. Therefore, the approach taken matters. It is argued that the measures used in traditional growth accounting to gauge the importance of investment-specific technological progress have little economic content, unlike the measure obtained from quantitative theory.  相似文献
