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.     

Can the Risks of the Kyoto Mechanisms be Reduced Through Portfolio Diversification? Evidence from the Swedish AIJ Program

Through Joint Implementationand the Clean Development Mechanism, reductionsof greenhouse gas emissions achieved abroad canbe credited to domestic firms. However, thetechnical, economic and political risksinvolved may prevent the private sector frominvesting in such projects. This paperdescribes three types of risks which emissionreduction projects are exposed to. Eleven pilotprojects carried out under the ActivitiesImplemented Jointly (AIJ) program and financedby Sweden are evaluated. Actual project costsare found to exceed projected costs in allcases. Annual emission reductions also deviatefrom their expected values and vary stronglyover time, supporting the hypothesis that suchprojects are risky business. The riskmanagement tool portfolio diversification isapplied to a sample of Swedish AIJ projects.The results indicate that diversification canreduce the risks of greenhouse gas mitigationprojects significantly. Thus, carbon funds area promising way of lowering the risks of theKyoto Mechanisms for private sector investors.     

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。     

The optimal portfolio for the two-pillar mandatory pension system: the case of Poland

In the recent decade, there has been observed across the Central and Eastern European states the regulatory trend towards the increase of the non-financial (first) pension pillar size at the expense of the financial (second) pillar. It tends to question the consequences of this shift for the future retirement benefits. Applying the portfolio approach we address this issue by running a series of simulations to find out how to allocate pension contributions between both pillars in an optimal way. Our study contributes to the existing literature as follows. First, we do not perform the assessment of the predetermined regulatory solutions, but we look for an optimal one. Moreover, we allow our optimal rule to be time-varying, if necessary, which would be a true novelty in this research area. Second, we do not base our estimates on historical trends; rather, we apply the long-term economy’s projection to account for the society’s ageing impact, which is a crucially important factor for the solvency of the pension system. Adapting some of the simulation assumptions to fit the Polish case, our results confirm that current regulations underestimate the role of the capital pillar and the optimal allocation between both pillars should be time-varying.

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.     

用产品生命周期进行财务管理

本文扩展了产品生命周期模型，提出用产品生命周期进行财务管理的系统模型。在产品生命周期的每一阶段，应采取不同的财务策略。同时。应保持足够的战略柔性，适时修正已经制定的财务战略以最大化企业的利益和股东的利益。财务战略的制定和执行要从公司作为一个整体的角度来进行，应与公司的其它职能部门进行必要的协调以实现公司的目标。
