Econometric modelling in finance and risk management: An overview

This paper gives an overview about the sixteen papers included in this special issue. The papers in this special issue cover a wide range of topics. Such topics include discussing a class of tests for correlation, estimation of realized volatility, modeling time series and continuous-time models with long-range dependence, estimation and specification testing of time series models, estimation in a factor model with high-dimensional problems, finite-sample examination of quasi-maximum likelihood estimation in an autoregressive conditional duration model, and estimation in a dynamic additive quantile model.     

物流包装设计的灰色多层次综合评价模型

物流包装的合理化是有效降低物流成本,提高物流效率的主要途径,对物流包装设计方案的定量评价是其中重要问题。在给出物流包装性能评价指标体系的基础上,建立了一种基于灰色系统理论的物流包装设计多层次灰色评价模型。最后给出了对三种方案进行综合评估的实例,结果表明灰色多层次评价法适用于对物流包装设计方案进行客观公正的综合评价,有力于促进物流系统总体最优化的运作。     

民营企业如何实现交接班

Economic Growth and Development: Towards a Catchup Model

We develop a model for economic growth applicable to a group of countries, constituting around half of the gross global production, that have been consistently “catching up” to the US since 1960 or so. This group can be termed “the convergence club.” The model has a theoretical basis developed in other publications (cited), but the present work is essentially empirical. It demonstrates that there is a very strong correlation between “catchup” growth, with respect to the US, and an energy proxy (EP). The energy proxy that works best is a linear combination of domestic electric power consumption petroleum (oil) consumption, per capita, compared to the US levels. The results presented here do not constitute a theory of growth, but they are consistent with theory presented elsewhere. On a practical level, we argue that consistent “catchup” trends over the past 40 years can safely be extrapolated for a few more decades for scenario construction purposes. We also believe that the observed catchup trends can be regarded as “potential” mid-term or long-term growth trajectories for transition economies and others that have recently been adversely affected by conflict or mismanagement.
