从社会保障角度研究人工成本与企业成本竞争力的关系

人工成本低廉一直是我国企业重要竞争优势所在。但是,随着经济的发展和工资水平的逐渐提高,以及我国社会保障制度的日益健全,国际经济体系中企业责任要求日益完备,企业继续采取低工资、低成本进行国际竞争的空间越来越小。基于此,对我国目前的人工成本状况进行分析,从社会保障的角度提出相关对策,对于维持和提高我国企业成本竞争力,促进国民经济发展,构建和谐社会具有重要的现实意义。本文的目的就在于对这个问题进行一些初步的探讨。     

价格规制、煤炭资源与能源约束:最优开发路径试解

煤炭在国民经济具有重要的战略地位。煤炭资源可持续利用的成本核算构成要素和现阶段我国煤炭资源成本核算存在一些问题。政府必须对煤炭资源进行价格规制,使煤炭价格能充分体现煤炭产业科学发展的要求,形成煤炭资源可持续利用的价格机制。     

金融管制理论和方法的演进

管制经济学通常包括经济性管制、社会性管制和反托拉斯管制三大部分。其中经济性管制研究的是自然垄断领域和存在严重信息不对称领域,后者典型的表现形式如金融业。一般的管制经济学因金融业内容丰富,需要独立的研究而较少涉及。而多数金融业管制研究侧重于监管的层面。文章从管制思想的演进、管制理论对金融业的实证研究、金融业管制经济分析和金融管制方法最新进展四个方面对金融管制经济理论进行分析和评述。     

Firm-level political risk and implied cost of equity capital

I find a strong positive association between firms' implied cost of equity capital and firm-level political risk. This effect is above and beyond the firm-level cost of equity implications of economywide political risk. Firm-level political risk contributes to elevating stock illiquidity, increases dispersion of analyst forecasts and dampens analyst coverage and these attributes, in turn, have positive cost of equity capital implications. Overall, the findings of this study suggest firm-level political risk has a non-trivial effect on increasing equity market illiquidity, increasing dispersion of earnings forecasts and decreasing analyst coverage thus increasing financing costs.     

价格歧视下四种市场类型的消费者剩余

市场按垄断程度由高到低可以分为四种类型：完全垄断市场、寡头垄断市场、垄断竞争市场和完全竞争市场。在发生二度价格歧视的情形下,这四种市场的价格歧视程度的定量结果是一个值得研究的问题。在二度价格歧视下,用微分法研究了一个垄断厂商市场情形,用博弈论方法研究了n厂商市场情形的均衡总产量,均衡价格,均衡总收益,总收益增长率,消费者剩余,厂商占有的消费者剩余率。最后把各种市场情形的上述指标归纳为统一的公式并详细分析了其性质。     

基于中国股市微观结构的流动性与执行成本分析

运用市场微观结构理论来分析中国股市的交易制度、流动性和执行成本后发现:(1)在佣金和交易税相等的条件下,B股的知情交易者执行成本普遍大于A股,导致B股的流动性小于A股,买卖价差显著大于A股,表明投资者对B股交易要求较高的风险报酬;(2)一旦控制住执行成本中普通交易者对知情交易者所要求的风险补偿,A、B股买卖价差的区别就消失了。因此,证券管理部门应在B股市场引入做市商制度并在微观结构理论的指导下,加强交易监管系统,从而提高B股的流动性并降低其执行成本。     

Environmental Valuation with Imperfect Information The Case of the Random Utility Model

This paper considers welfare analysis with therandom utility model (RUM) when perceptions ofenvironmental quality differ from objectivemeasures of environmental quality. Environmental quality is assumed to be anexperience good, so that while perceptions ofquality determine choices, ex postutility is determined by objective quality. Given this assumption, I derive a measure ofthe welfare impact of changes in environmentalquality, and I show how this new welfaremeasure differs from the traditional welfaremeasure developed by Hanemann (1982). This newwelfare measure provides an approach tomeasuring the value of information aboutenvironmental quality within the framework ofthe random utility model.     

Back to Buchanan? Explorations of welfare and subjectivism in behavioral economics

In light of behavioral findings regarding inconsistent individual decision-making, economists have begun to re-conceptualize the notion of welfare. One prominent account is the preference purification approach (PP), which attempts to reconstruct preferences from choice data based on a normative understanding of neoclassical rationality. Using Buchanan’s notion of creative choice, this paper criticizes PP’s epistemic, ontological, and psychological assumptions. It identifies PP as a static position that assumes the satisfaction of given ‘true preferences’ as the normative standard for welfare. However, following Buchanan, choice should be understood dynamically as a process whereby preferences constantly regenerate. Accordingly, the meaning of welfare emerges from an ongoing quest for individual self-constitution. If this holds true, then rationality axioms cannot serve as a priori normative standards. Instead, creative imagination and learning processes must remain central to any understanding of welfare in economics.     

Governance structures in R&D networks: An analysis in the European context

This paper analyses governance structures used to organize partnerships in R&D networks using two approaches: transaction costs theory and social capital theory. We argue that these theories are complementary; this explains forms of governance through the degrees of administrative (structural and safeguard mechanism) and social factors (cohesion and openness) they embody. Data was obtained from European R&D networks created through Framework Programmes which include a great number of universities, non profit institutions and firms. Findings show the variables that characterize and explain the governance forms based on the applicability of R&D networks. This study not only provides a theoretical model for analysing governance structures of these networks, but is also useful for both improving the management of networks and for fostering collaboration at an international level.
