Deliberative monetary valuation (DMV): Issues in combining economic and political processes to value environmental change

This paper explores and contrasts the different social processes of valuation now appearing as economic means of valuing the environment. Monetary valuation via stated preference approaches has been criticised for assuming well formed and informed preferences and excluding a range of sustainability concerns such as rights, fairness and equity. Deliberative monetary valuation (DMV) in small groups is a novel hybrid of economic and political approaches which raises the prospect of a transformative and moralising experience. Critics of standard contingent valuation approaches have advocated this as offering a way forward. However there has been a lack of clarity as to the means of obtaining values, the expected outcomes and their role. Moving to group settings of deliberation raises concepts of social willingness to pay and accept which are distinct from an aggregate of individual value, although this does not seem to have been widely recognised. A new classification of values is presented appropriate to the literature trying to merge economic and political processes. Values associated with the individual may be exchange values, charitable contributions or fair prices, while social values can be speculative, expressive or arbitrated. The use of DMV is shown to result in different values due to variations in the institutional setting and process of valuation.     

科斯《企业的性质》之质疑

企业是资源所有者的取得更多的收益而建立起来的经济组织，交易成本的存在并不是企业存在的根本原因，科斯将企业定义为不同于价格调节机制的企业家计划调节机制，源于其错将企业计划混同于计划经济，事实上，企业是以市场合约为基础形成的，按市场运行原则运作的市场性组织，其资源配置并不独立于市场价格机制之外，价格调节机制与企业家调节机制是不可分割的两个方面，任何企业作为市场参与者与市场都是互动的。     

Regulation of Stock Externalities with Correlated Abatement Costs

We study a dynamic regulation model where firms’ actions contribute to a stock externality. The regulator and firms have asymmetric information about serially correlated abatement costs. With price-based policies such as taxes, or if firms trade quotas efficiently, the regulator learns about the evolution of both the stock and costs. This ability to learn about costs is important in determining the ranking of taxes and quotas, and in determining the value of a feedback rather than an open-loop policy. For a range of parameter values commonly used in global warming studies, taxes dominate quotas, regardless of whether the regulator uses an open-loop or a feedback policy, and regardless of the extent of cost correlation.Early versions of this paper were presented at the Fifth California Workshop on Environmental and Resource Economics, University of California, Santa Barbara, CA, May 5–6, 2000, and at the annual meeting of the Canadian Agricultural Economics Society, University of British Columbia, Vancouver, BC, Canada, June 1–3, 2000.

高新技术产业投资、沉淀成本与补偿制度创新

高新技术产业投资对我国国民经济发展具有重要的作用和潜在的扩张力,但由于没有充分利用高新技术产业投资,严重影响国民经济的整体发展.为此,本文从沉淀成本角度出发,使用一个动态的投资模型,探讨高新技术产业投资所面临的障碍以及提供刺激高新技术产业投资的基本原则,在于完善投资成本补偿机制:一方面,需要大力完善市场制度;另一方面,更需要大力完善非市场制度,同时,政府折旧和税收政策等也是不可替代的.     

The origin of money: A survey of the contemporary literature

Introducing money into a scheme of general economic equilibrium entails manifold problems, which have emerged in many contributions to the literature. Some of these problems have been adequately addressed at the level of micro-based approaches which can be traced back to the monetary theory of Carl Menger. In this survey we shall review such issues, after which we shall attempt to illustrate the contribution to solving the problem of the origin of money offered by the literature on transaction and information costs inspired by Menger's monetary theory.

Liquidity and Liquidation

The manager of a firm that is selling an illiquid asset has discretion as to the sale price: if he chooses a high (low) selling price, early sale is unlikely (likely). If the manager has the option to default on the debt that is collateralized by the illiquid asset, the optimal selling price depends on whether the manager acts in the interests of owners or creditors. We model the former case. In equilibrium the owner will always offer the illiquid asset for sale at a strictly higher price than he paid, and will default if he fails to sell. As a result, upon successful sales the illiquid asset changes hands at successively higher prices. We also consider a generalization of the model which permits sellers to finance sales using either debt or preferred stock, or both. This allows derivation of an optimal capital structure.

Spatial and supply/demand agglomeration economies: State- and industry-linkages in the U.S. food system

Cost-impacts of spatial and industrial spillovers on economicperformance are evaluated by incorporating activity level measures for nearby states and related industries into a cost function model. We focus on localization and urbanization economies for state level food processing industries, from activity levels of similar industries in neighboring states, agricultural input suppliers, and final product demand. We find significant cost-savings from proximity to other food manufacturing centers, and areas with high purchasing power. Cost savings from locating near an agricultural area are also evident, although it seems costly to be located within a rural agricultural state, implying thin market diseconomies. Marginal production costs instead appear higher in more urban, and lower in more rural, areas. These spillover patterns also have input composition implications; materials demand responses are the most closely tracked by the agglomeration cost effects, and capital and labor impacts vary.     

Labor adjustment costs and complex eigenvalues

Aggregate variables display both persistence and damped oscillations in response to temporary external shocks. The standard real business cycles (RBC) model cannot explain these patterns, because its stable eigenvalues are positive and real. We demonstrate that this model with labor adjustment costs can yield complex eigenvalues. However, numerical experiments suggest that the model cannot display distinguishable damped oscillations of aggregate variables.
