Variation diminishing property of densities of uniform generalized order statistics

Let f _*,r , r ≥ 1, denote the density function of rth uniform generalized order statistics as defined by Kamps (1995) or Cramer and Kamps (2003). We prove the following variation diminishing property: the number of zeros in (0,1) of any linear combination does not exceed the number of sign changes in the sequence (a ₁, . . . ,a _r ). This result is applied to study monotonicity and convexity properties of f _*,r .     

Technological knowledge as an essential facility

The economics of regulation has articulated the notions of essential facility and mandated interconnection. Their application to the governance of technological knowledge can be fruitful especially when implemented by the adoption of a compensatory liability rule and the parallel reduction in the exclusivity of patents. Because knowledge is at the same time an output and an input in the production of new knowledge, exclusivity, traditionally associated to patents, is the cause of actual knowledge rationing with major drawbacks in terms of both static and dynamic efficiency. This institutional innovation can improve the governance of technological knowledge and increase both its rates of dissemination and generation.

Property rights and information flows: a simulation approach

With the growth of the information economy, the proportion of knowledge-intensive goods to total goods is constantly increasing. Lessig (The future of ideas: the fate of the commons in a connected world. Vintage, New York 2001) has argued that IPRs have now become too favourable to existing producers and that their ‘winner-take-all’ characteristics are constraining the creators of tomorrow. In this paper we look at how variations in IPRs regimes might affect the creation and social cost of new knowledge in economic systems. Drawing on a conceptual framework, the Information Space or I-Space to explore how the uncontrollable diffusibility of knowledge relates to its degree of structure, we deploy an agent-based modelling approach to explore the issue of IPRs. We take the ability to control the diffusibility of knowledge as a proxy measure for an ability to establish property rights in such knowledge. Second, we take the rate of obsolescence of knowledge as a proxy measure for the degree of turbulence induced by different regimes of technical change. Then we simulate the quantity and cost to society of new knowledge under different property right regimes.

恶意挤占医保基金的经济学分析

导致医保基金存量减少的原因可以分为两类,一类由客观原因导致,并且难以避免,另一类是人为因素造成的恶意挤占医保基金的行为。针对后一种情况,从经济学角度,首先运用产权理论的观点来分析制度本身的缺陷,再通过建立两个博弈模型来分析当事人投机心理的形成过程,并提出相应解决措施。     

重庆“钉子户”事件的物权法分析

重庆"钉子户"事件引起了社会的广泛关注。该事件的产生涉及若干《物权法》上的问题,也反映了目前我国城市房屋拆迁制度存在的缺陷。弥补这些缺陷应在《物权法》中明确界定"公共利益"的范围、确定拆迁补偿的规则,从而进一步完善《物权法》中的征收制度。     

罗马法所有权及对我国所有权制度完善的影响

罗马法的物权概念是现代民法物权概念的基础,罗马法中的所有权更是具备了现代民法中所有权的主要内容.我们应借鉴罗马法所有权并结合我国所有权的立法和实践,对社会主义市场经济条件下的所有权制度进行理论创新和实践改革.     

关系型交易对审计费用的影响——基于经营风险理论视角

关系型交易模式可能会在议价能力、关系专用性投资成本转换等方面加剧上市公司的经营风险,进而影响审计费用。已有研究主要集中于关系型交易对审计行为的影响,鲜有文献关注其中的作用机制。本文基于经营风险理论视角,选取2008~2017年沪深A股制造业上市公司的相关数据,实证分析了关系型交易对审计费用的影响,结果表明:关系型交易显著加剧了企业经营风险的集聚,进而提升审计费用,即经营风险在关系型交易对审计费用的影响中起到了中介作用。进一步研究,在区分了产权性质以及耐用品特征后,实证结果显示关系型交易与审计费用的正相关关系在非国有企业以及耐用品行业的企业中较为显著,为审计师进行合理审计定价提供了经验证据支持。     

我国农用化肥施用的影响因素——基于省际面板数据的实证分析

我国农用化肥施用量不断提高带来的环境污染问题日益严重。研究化肥施用的影响因素及其影响程度,为防止化肥滥施、保护生态环境提供依据意义重大。文章采用1999～2008年我国31个省(市、区)的面板数据,通过面板单位根检验、协整关系检验和多元回归方法分别对国内东、中、西三大区域化肥施用密度与其影响因素之间的关系进行了实证分析。研究结果表明,三大区域农民人均纯收入、人口规模对化肥施用密度具有显著的正向影响,三大区域化肥价格增长率、粮食种植面积比重、化肥产出效率对化肥施用密度具有显著的负向影响,三大区域种植产品生产价格、种植业劳动力数量、农产品国际贸易对化肥施用密度具有不同的影响效果或显著性。     

企业技术创新的虚拟与实体产权激励

企业技术创新激励制度的核心是保护创新者的利益,产权激励制度是一种合理的方式。企业技术创新的产权激励制度设计原则是保证创新收益与风险的均衡。知识产权激励是产权激励的重要内容。对技术创新的产权激励不仅仅是企业内部人员的激励或者外围环境的激励,本文力图建立一个以企业作为分析边界的产权激励模式。对技术创新的产权激励从产权形式角度划分为虚拟和实体产权。企业主体虚拟产权包括以品牌价值增值权为体现的声誉收益权,企业内部成员虚拟产权体现为以影子股票或者股票期权等形式的远期剩余索取权。从企业边界角度,内部产权激励中股权激励包括虚拟股权激励和现实股权激励,外部产权激励包括政府的知识产权制度。此外,企业技术创新的产权界定与保护制度是虚拟与实体产权激励制唐的保证．
