Contract modifications and the basis behavior of live cattle futures

The purpose of this study was to assess the basis behavior of the Live Cattle Futures contract at the Chicago Mercantile Exchange (CME) before and after the 1995 contract changes. Additionally, an alternative method of basis calculation utilizing weighted mean futures prices versus settlement futures prices was compared to determine which method provides a better representation of the basis level. Within a regression model with heteroskedascity error framework, we found that the level of nearby basis in the period after June 1995 has shifted lower and the average monthly open interest of net commercial long positions has substantially increased after the contract modifications. These empirical results are consistent with the notion that more long activity entered the market in response to the contract modifications. Additionally, an alternative (new) measure of basis calculation (cash price minus weighted mean futures price) produced similar results to two other commonly used measures. In conclusion, the 1995 contract changes have neither increased nor decreased the volatility of live cattle basis. © 2004 Wiley Periodicals, Inc. Jrl Fut Mark 24:557–590, 2004     

Minimum and preferred entry qualifications and training provision for North Australian workers

This paper reports on the outcomes of a replication study of a survey of British employers that requested information on the qualifications sought when recruiting employees and on subsequent training and development. While the British survey was interested in the uptake and use of the British National Vocational Qualifications, the study reported in this article is primarily focused on the uptake and use of the Australian Qualifications Framework qualifications by North Australian employers. This study was prompted by the skills shortages and recruitment difficulties being experienced by organizations throughout rural and regional Australia. Previous studies have found that vocational qualifications were not valued by UK employers and few employers were encouraging employees to undertake vocational awards. If this is also the case in Australia, it may in part explain problems in recruiting skilled workers. This research clearly demonstrates that employees in regional and rural Australia are seeking to improve their knowledge and skills through vocational training and higher education qualifications. Also, employers are providing access to training and are supporting managerial and professional employees to gain higher educational qualifications. When recruiting all types of worker other than unskilled labourers, the majority of organizations prefer to recruit workers with qualifications. In rural and regional centres, however, a more pragmatic stance of recruiting unqualified employees in some areas is observed. Clearly, employers will attempt to minimize training costs by recruiting skilled employees, but in the end they will have to provide access to training and education to ensure that they have a skilled workforce that can deliver essential services and products.     

循环经济的投入产出分析

本文运用投入产出理论对循环经济进行了量化分析，首先，在模型中将循环经济部门从生产部门和消除污染部门中分离开来，在投入不变的条件下，运用循环经济下的各种经济指标来研究新的投入产出关系。其次，通过比较研究的方法，来分析循环经济对整个国民经济的影响程度及对其效果进行评价。最后本文还探讨了在不引入循环生产部门的情况时循环经济的投入产出关系。

浅议企业绩效评价业务

关于企业绩效评价业务据财政部统计评价司的阐述,所谓企业绩效评价,是指运用数理统计和运筹学原理,特定指标体系,对照统一的标准,按照一定的程序,通过定量定性对比分析,对企业一定经营期间的经营效益和经营者业绩做出客观、公正和准确的综合评判。需指出的是,当前我国企业信息管理领域正逐步流行的ERP,也同样需要企业绩效评价,不过它与我们这里所讲的企业绩效评价是两个不同的概念,ERP中采用的企业绩效评价是特指评价其资源管理项目实施的效益和企业整体应用ERP后的效果。我国当前实施的企业绩效评价,实质上是按照市场经济要求实行的一…     

路过天空——深圳航空平面广告创意手记

The mean-variance investment problem in a constrained financial market

This paper extends the mean-variance analysis and the two-fund separation theorem to a market with some constraints, such as, the incompleteness, prohibition of short-selling, and partial information, with stochastic interest rate, and with stochastic volatility for risky assets. By maximizing a quadratic utility of terminal wealth, we show that the efficient frontier for the problem is a straight line in the mean-standard-deviation diagram. The quadratic utility function exhibits mean-variance efficiency. Our results apply to portfolios of claims in a single period, multiperiod, and continuous time.
