农药企业社会责任指标体系与评价方法

企业社会责任评价体系是企业履行社会责任的指南和准则,是引导和规范企业行为的信息工具,是农药企业社会责任从定性研究到定量评价、从理论到实践的桥梁和纽带。本文在构建指标体系原则指导下,设计了农药企业社会责任综合评价指标体系,从经济效益、创新能力、产品质量、售后服务、环境保护、员工权益、社区关系和慈善公益八个方面设计指标反映农药企业社会责任评价所包含的主要内容,并利用层次分析法确定了不同子目标和指标的权重,同时就企业间横向比较和单一企业纵向比较两种情形,分别给出了社会责任综合评价的方法。     

企业价值评估方法研究

企业价值评估诸多方法中,现金流指标的重要性日益显现,其中,自由现金流量最具可行性。企业规模 的大小、发展的阶段和经营的盈亏成为影响企业现金流的基本内因,而季节性、周期性和竞争是其外因。企业价值评 估从企业历史业绩分析开始,再预测未来绩效,并评估连续价值,最终确定企业价值总额。

北京先行经济指数研究

"北京先行经济指数"是我国第一个区域性先行经济指数,在试运行中取得了很好的效果。该指数以我国现行统计制度为基础,紧密结合北京实际,通过构造基准循环、"提取"先行指标、编制指数、返回检验等步骤,对北京先行经济指数的科学性和有效性进行了分析。先行指数超前GDP增速变化4～8个月这一重要研究结论在返回检验中得到了很好的证实。

Intraday Empirical Analysis and Modeling of Diversified World Stock Indices

This paper proposes an approach to the intraday analysis of diversified world stock accumulation indices. The growth optimal portfolio (GOP) is used as reference unit or benchmark in a continuous financial market model. Diversified portfolios, covering the world stock market, are constructed and shown to approximate the GOP, providing the basis for a range of financial applications. The normalized GOP is modeled as a time transformed square root process of dimension four. Its dynamics are empirically verified for several world stock indices. Furthermore, the evolution of the transformed time is modeled as the integral over a rapidly evolving mean-reverting market activity process with deterministic volatility. The empirical findings suggest a rather simple and robust model for a world stock index that reflects the historical evolution, by using only a few readily observable parameters.

Hedging Housing Risk*

An unusually rich source of data on housing prices in Stockholm is used to analyze the investment implications of housing choices. This empirical analysis derives market-wide price and return series for housing investment during a 13-year period, and it also provides estimates of the individual-specific, idiosyncratic, variation in housing returns. Because the idiosyncratic component follows an autocorrelated process, the analysis of portfolio choice is dependent upon the holding period. We analyze the composition of household investment portfolios containing housing, common stocks, stocks in real estate holding companies, bonds, and t-bills. For short holding periods, the efficient portfolio contains essentially no housing. For longer periods, low-risk portfolios contain 15 to 50 percent housing. These results suggest that there are large potential gains from policies or institutions that would permit households to hedge their lumpy investments in housing. We estimate the potential value of hedges in reducing risk to households, yet yielding the same investment returns. The value is surprisingly large, especially to poorer homeowners.
