考虑社会责任的异质有限理性制造商产量博弈均衡复杂动力学分析

通过考虑消费者剩余,企业利润中引入承担社会责任参数,建立了具有异质性有限理性的古诺寡头博弈竞争模型,分析利润相关参数对系统博弈均衡稳定性的影响,并进行了数值模拟。研究表明单方有限理性系统比双方有限理性系统稳定。产品成本超过一定阈值应避免产量竞争,可以通过承担社会责任,提升产品价格来增加利润,但当企业承担社会责任增加时,系统稳定性降低。此时降低调整产量的速度,观察竞争对手产量调整速度,避免系统进入混沌状态,失去最优产量优势。     

Minimum Quality Standards under Asymmetric Duopoly with Endogenous Quality Ordering: A Note

In this note, we revisit minimum quality standards (MQS) under a vertically differentiated duopoly. We generalize the model in Ronnen (1991) and Valletti (2000) by introducing asymmetry into the fixed cost of quality improvement and by explicitly taking into account the endogeneity of quality ordering. In the generalized model, we show that the results derived by Ronnen (1991) and Valletti (2000) are largely robust.     

Natural resource accounting for Indian states — Illustrating the case of forest resources

Our main objective is to set out and apply a SEEA-based methodology to reflect the true value of forest resources in India's national and state accounts. We establish that a “top-down” approach using available national databases is both feasible and desirable from a policy perspective. In this paper, we address four components of value creation in forests: timber production, carbon storage, fuelwood usage, and the harvesting of non-timber forest products. The results of our analysis suggest that prevailing measures of national income in India underestimate the contribution of forests to income. The income accounts of the Northeastern states in particular are significantly understated by these traditional (GDP/GSDP) measures. We are also able to identify some states which performed poorly in the context of our sustainability framework, reflecting natural capital losses due to degradation and deforestation. Our results highlight the need to integrate natural resource accounting into the national accounting framework in order to generate appropriate signals for sustainable forest management and for the conservation of forest resources which are widely used by the poor in India, as well as being significant stores of national wealth.     

我国体验式旅游开发初探

文章从体验式旅游内涵出发,研究分析了我国体验式旅游开发的现状及环境。指出现阶段我国体验式旅游开发仍处于增加体验环节和体验要素的初级阶段。其开发应分两步走:首先从提供旅游(服务)产品转向提供体验型旅游产品(体验旅游开发的初级阶段);再则从提供体验型旅游产品到提供旅游体验(体验旅游开发的成熟阶段)。目前,国内应重点开发体验型旅游产品。

Deregulating Network Industries: Dealing with Price-quality Tradeoffs

This paper examines the effects of introducing competition into monopolized network industries on prices and infrastructure quality. Analyzing a model with reduced-form demand, we first show that deregulating an integrated monopoly cannot simultaneously decrease the retail price and increase infrastructure quality. Second, we derive conditions under which reducing both retail price and infrastructure quality relative to the integrated monopoly outcome increases welfare. Third, we argue that restructuring and setting very low access charges may yield welfare losses, as infrastructure investment is undermined. We provide an extensive analysis of the linear demand model and discuss policy implications.     

新古典生产函数的质疑与货币量值的生产函数

新古典理论以生产函数和效用函数为基础,建立了技术关系的稀缺资源有效配置理论,其核心是表明商品和要素稀缺性的相对价格.生产函数在微观尚可应用,但并不能用于解释总量经济和经济增长与波动问题.尤其是总供给完全取决于实物生产函数的投入产出关系,这与总需求分析所采用的货币支出是不协调的.货币量值的生产函数的推导表明,总供给只是企业的货币成本函数而不联系到技术上的投入产出关系,而所有的国民收入核算中的货币量值都只是表明人们经济关系的名义变量而与实物的技术关系或生产函数是完全无关的.     

世博会标志许可产品的产品责任及风险防范探讨

世博会标志许可经营是中国2010年上海世博会商业化运作的主要内容之一。如果世博会标志许可产品存在缺陷,并且生产企业没有在产品上标明其商标或其他明显识别性标志时,世博会标志权利人存在承担产品责任的风险,对此风险应从合同、质量保证金、产品责任险、监督检查等方面加强防范。
