This empirical study of business‐to‐business service firms examines the determinants and effects of control rights to intellectual assets in a property rights theoretic framework. Regression analyses using survey data suggest that service suppliers that retain control over their intellectual output are more innovative. In long‐term relationships, service firms' clients may thus be better off balancing their need to control outsourced activities with the suppliers' incentives to invest in learning and innovation. Additionally, and aligned with property rights theoretic predictions, service suppliers' bargaining power and their indispensability in service projects are positively associated with their ability to retain control rights. In contrast, innovation capabilities are not very significant in determining control rights allocation between service suppliers and their clients. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

超产权理论刍议——兼评“超产权论与企业绩效” 总被引:1,自引:0,他引:1
产权理论是以产权为基本分析工具来研究企业的治理结构与绩效的关系。而超产权理论试图改变这一基本分析范式,以“竞争性”代替产权作为企业治理结构与绩效的基本分析工具。比较和分析这两种理论可看出,超产权理论所主张的竞争性分析方法并不能取代传统的产权分析,产权结构是决定企业治理结构和绩效的最基本制度因素,产权理论仍然是进行企业分析的合理有效的基本方法。 相似文献

Conditional probability distributions seem to have a bad reputation when it comes to rigorous treatment of conditioning. Technical arguments are published as manipulations of Radon–Nikodym derivatives, although we all secretly perform heuristic calculations using elementary definitions of conditional probabilities. In print, measurability and averaging properties substitute for intuitive ideas about random variables behaving like constants given particular conditioning information.
One way to engage in rigorous, guilt-free manipulation of conditional distributions is to treat them as disintegrating measures—families of probability measures concentrating on the level sets of a conditioning statistic. In this paper we present a little theory and a range of examples—from EM algorithms and the Neyman factorization, through Bayes theory and marginalization paradoxes—to suggest that disintegrations have both intuitive appeal and the rigor needed for many problems in mathematical statistics. 相似文献

本文认为,马克思的劳动价值论是以“简单商品经济”为基础构建起来的,“转化”理论是马克思劳动价值理论由“简单商品经济”通向资本主义现存生产方式的桥梁,它使马克思劳动价值论不再仅仅局限于“简单商品经济”的范围,而是其全部理论的支点。然而它在马克思的劳动价值理论中并非是一种完全自洽的存在,它在解释资本主义社会现实经济活动方面,本身也存在一些局限,留下了一些值得思考的问题。 相似文献

建国以来,党的农业生产力发展观经历了探索、调整和完善的过程。第一代领导集体的农业生产力发展观偏重于农业制度的改革,进行了以集体组织下改革农业技术的实践,因忽视农民积极性和生产力系统的协调性,其实践效果差。第二、三代领导集体改变了党对农业的领导方式,高度重视农民积极性和生产力系统的协同性,形成了包括发挥农民积极性、现代工程和生物技术与传统农业技术相结合、市场农业和尊重自然规律为内容的农业生产力发展观。这是中国当代农业生产力发展的成功经验,也是党对传统农业重视天地人协调经验的继承。 相似文献

Benartzi and Thaler [The Quarterly Journal of Economics 110 (1995) 73–92] offer a quasi-rational explanation for the equity premium puzzle. We reconsider their methodology and, making a simple modification to it, find that their analysis is not robust. 相似文献

深化对马克思企业理论的研究既有助于澄清一些人认为“马克思没有企业理论”的误解,也有助于纠正企业理论研究中“言必称西方”的倾向,还可以为我国的企业改革实践提供指导。研究的途径有“回到马克思”、“依据变化了的实际分析马克思企业理论的‘合理内核’与时代局限”、“批判性地借鉴西方经济学的企业理论”等。 相似文献

会计目标一直是西方会计界重点关注和研究的问题,近年来,我国会计理论界和实务界也对其投以越来越多的关注。本文试图从企业产权理论和制度变迁的角度,以利益相关者权益保护为主线研究会计目标,理清从受托责任观到决策有用观演进的必然性和合理性,并在分析英美、法德模式会计目标的差异后,结合当前我国会计准则国际趋同的背景,提出我国应确立以利益相关者权益保护为中心、以企业特征为导向、针对不同环境分别选择受托责任或决策有用为核心内容的会计目标构建思想。 相似文献

Statistical Decision Problems and Bayesian Nonparametric Methods 总被引:1,自引:0,他引:1
This paper considers parametric statistical decision problems conducted within a Bayesian nonparametric context. Our work was motivated by the realisation that typical parametric model selection procedures are essentially incoherent. We argue that one solution to this problem is to use a flexible enough model in the first place, a model that will not be checked no matter what data arrive. Ideally, one would use a nonparametric model to describe all the uncertainty about the density function generating the data. However, parametric models are the preferred choice for many statisticians, despite the incoherence involved in model checking, incoherence that is quite often ignored for pragmatic reasons. In this paper we show how coherent parametric inference can be carried out via decision theory and Bayesian nonparametrics. None of the ingredients discussed here are new, but our main point only becomes evident when one sees all priors—even parametric ones—as measures on sets of densities as opposed to measures on finite-dimensional parameter spaces. 相似文献

By means of a straightforward application of empirical process theory, we show that S-estimators of multivariate location and covariance are asymptotically equivalent to a sum of independent vector and matrix valued random elements respectively. This provides an alternative proof of asymptotic normality of S-estimators and clearly explains the limiting covariance structure. It also leads to a relatively simple proof of asymptotic normality of the length of the shortest α-fraction. 相似文献
