Eco-logical education for the long emergency

In its inadvertent creation of multiple ecological crises including climate change, humanity as a whole appears caught in a lemmings loop, racing toward a probable future identified as The Long Emergency. One might think that even the possibility of this future scenario should be sufficient to effect a revolution in education. Yet overall there appears to be insufficient depth of respons-ability in this regard, of taking heed of ecological educational discourse. The paper advocates a deeply ecological education through identifying the significance of ecoliteracy as involving a critical contrast between two worldviews (modernism and a prospective ecological worldview). The paper advances futures of ecological thinking through a deep interpretation of ecology and related terms including ecosystem and eco-logics. The complex integrative character of conceptual ecology is foregrounded and extended through associating it with transdisciplinarity, integralism and critical realism under the overarching orientation of Boyer's scholarship of integration.

外资并购--漫漫双赢路

随着国际并购浪潮阵阵袭来,我们的国有企业也搭上了顺风车,但是,正如美国克纳公司主席兼执行官福雷德·施泰因格雷伯指出的那样:尽管目前收购案创下历史最高水平,但其结果是令人失望的,近60％～80％的案件是失败的,或者说没有达到预期的目标。在国有企业改革举步唯艰之时,我们最应该关心的是怎样达到“双赢”,如何营造外资企业与国有企业“双赢”的局面。     

Risks for the long run: Estimation with time aggregation

The discrepancy between the decision and data-sampling intervals, known as time aggregation, confounds the identification of long-, short-run growth, and volatility risks in asset prices. This paper develops a method to simultaneously estimate the model parameters and the decision interval of the agent by exploiting identifying restrictions of the Long Run Risk (LRR) model that account for time aggregation. The LRR model finds considerable empirical support in the data; the estimated decision interval of the agents is 33 days. Our estimation results establish that long-run growth and volatility risks are important for asset prices.

Causal mechanisms of long waves

Previous research on the causes of economic growth maintains that long waves of economic development arise as a result of Schumpeterian innovation. This paper builds on this research by introducing four primary causal mechanisms for the long wave of economic development. The causal mechanisms are classified based on level of analysis. The paper argues that describing causal mechanisms by level of analysis allows researchers to more easily draw from various fields and establish needed consensus in long wave theory.     

Power laws and long memory

Thomas Lux comments on the paper by Blake LeBaron, on page 621 of this issue, by recalling related findings of spurious scaling properties and questions whether we can distinguish between true and spurious scaling laws in finite data series.     

Analysing long memory and asymmetries

The paper presents evidence on nonlinearities in Finnish financial time series. The analysis concentrates on the so-called long-memory property which is examined using, various alternative test procedures. This analysis makes use of relatively long monthly Finnish time series which cover the period 1922–1996. The results give some evidence on long memory but one cannot say that the results would overwhelmingly support the existence of long memory in Finnish time series. There are, however, considerable differences between variables and the results are quite sensitive in terms of the treatment of short memory which also applies to different ways of prefiltering the data. Clearly more work is required to obtain more affirmative results in this respect. One way, of doing that is to apply asymmetric time models to find the source of nonlinearity. When that is done with the Finnish data some weak evidence on asymmetry is obtained.     

Block bootstrap methods and the choice of stocks for the long run

Financial advisors commonly recommend that the investment horizon should be rather long in order to benefit from the ‘time diversification’. In this case, in order to choose the optimal portfolio, it is necessary to estimate the risk and reward of several alternative portfolios over a long-run given a sample of observations over a short-run. Two interrelated obstacles in these estimations are lack of sufficient data and the uncertainty in the nature of the return generating process. To overcome these obstacles researchers rely heavily on block bootstrap methods. In this paper we demonstrate that the estimates provided by a block bootstrap method are generally biased and we propose two methods of bias reduction. We show that an improper use of a block bootstrap method usually causes underestimation of the risk of a portfolio whose returns are independent over time and overestimation of the risk of a portfolio whose returns are mean-reverting.     

Design for a technology: Assessment of coal

The objective of the coal technology assessment is to compare the environmental, social, economic, and institutional consequences that may arise from development of various mixes of coal-based energy technologies to the year 2030. This article presents the assumptions behind the method, the experience from two forums with interested parties, the three scenarios constructed for the study, and the result of one issue analysis, namely the effects of global carbon-dioxide buildup from coal combustion.

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…

对中国通货膨胀的基本判断及货币政策建议

中国宏观经济正处于一个通货膨胀的通道之中,但中国强有力的货币政策措施效果不显著。究其原因,在于本轮通货膨胀具有不同以往的外源性特征,其中包含了美国美元贬值阴谋。正因为中国通货膨胀仅仅是全球性通货膨胀的一部分,同时中国承担着全球性通货膨胀成本,因此解决通货膨胀问题,并非中国的"家务事"。在此背景中,针对国内通货膨胀问题,中国不能急于求成,而只能顺势而为,以财政政策为主,来弱化通胀之负作用。货币政策作为辅助性政策,仅需要保持从紧状态,避免信贷失控即可。
