Technological substitution in the United States pulp and paper industry: The sulfate pulping process

This paper presents an econometric analysis of the diffusion of the sulfate pulping process throughout the U.S. pulp and paper industry. A dynamic equilibrium, Gompertz diffusion function is employed to derive a multivariate estimation model which incorporates more information than the traditional approach of estimating the growth rate function alone. The empirical results suggest that the econometric approach provides a useful integration of the technological diffusion process and the comparative static theory of demand. The sulfate pulping process is projected to continue capturing market share at a relatively rapid rate, and could account for 90% or more of total U.S. woodpulp production by the year 2000.     

Telecommuting: The employee's perspective

Available telecommunication technology enables the substitution of commuting by “telecommuting”, or working at home, for a wide range of white collar occupations. Research on the potential of this phenomenon along with some ongoing experiments point at an array of social and personal benefits that may be realized by this working arrangement. An assessment of the possible implications of work-at-home on the individual employee indicate that the burden on him or her may be greater than the benefits accrued and, therefore, the journey to work may be a more desirable act than traditionally perceived by transportation planners. This paper focuses on two aspects of the work-at-home arrangement. Previous research on the sociology of work as well as preliminary empirical results indicate that 1) social interaction at work and 2) the need to separate home and work roles are important elements for the individual worker. The fact that work-at-home will affect these attributes, is likely to discourage wide-scale transition to this arrangement, despite the availability of the technology. Most research published to date on the subject is qualitative in nature, as only little empirical evidence is available. The objective of this paper is to stress, based on a wide literature review, the need for a thorough behavioral evaluation of the available technology to provide a sound basis for decision making on implementation of the technology.     

我国服务贸易进口与制造业出口竞争力关系研究

在统计我国服务贸易进口额和制造业11个重点行业出口额的基础上,以面板数据结合多元回归方法实证服务贸易进口与我国制造业出口竞争力关系。结果显示：①总体上我国服务贸易进口增长有利于制造业出口竞争力的提升;②不同部门服务贸易进口的增长对制造业出口竞争力提升的影响程度存在着较大差异;③服务贸易进口对不同部门制造业出口竞争力的影响也不一样。最后就我国制造业应该如何利用服务贸易进口来提高其出口竞争力提出了针对性的政策建议。

The Impact of Basel II on Lending to Small- and Medium-Sized Firms: A Regulatory Policy Assessment Based on Spanish Credit Register Data

The objective of this paper is to evaluate the impact on bank credit exposures to small- and medium-sized Spanish firms of the current proposal for reform of the 1988 Capital Accord using information from the Spanish Credit Register. Capital requirements for exposures to those firms, according to the various revisions of the proposed capital reform (from the January 2001 consultative document to the April 2003 one), are calculated to analyze whether the existing pattern of bank financing of small- and medium-sized firms might be altered. Finally, the incentives for individual banks to adopt the advanced internal ratings-based approach proposed by Basel II are evaluated.     

农产品质量安全监管的成本——效率分析

近年我国农产品质量安全问题日益凸显。导致农产品质量安全堪忧的市场不完全、信息不对称、外部性等市场失灵问题仅靠市场自身调节无法解决,需要加强政府调控与管理;而近年农产品质量安全事件频发,政府监管仍然不到位,原因在于政府监管成本过高。实现农产品质量安全的有效监管,必须整合政府资源、社会资源、个人资源,形成监管合力,构建全社会共同监管的局面,降低制度成本、社会监管成本和消费者的信息获得成本,提高农产品质量安全监管效率。     

Financial markets with volatility uncertainty

We investigate financial markets under model risk caused by uncertain volatilities. To this end, we consider a financial market that features volatility uncertainty. We use the notion of G-expectation and its corresponding G-Brownian motion recently introduced by Peng (2007) to ensure a mathematically consistent framework. Our financial market consists of a riskless asset and a risky stock with price process modeled by geometric G-Brownian motion. We adapt the notion of arbitrage to this more complex situation, and consider stock price dynamics which exclude arbitrage opportunities. Volatility uncertainty results in an incomplete market. We establish the interval of no-arbitrage prices for general European contingent claims, and deduce explicit results in the Markovian case.
