摘要： 厦门大学与新华社经济参考报8月18日在京联合举行2013中国宏观经济高层研讨会暨中国季度宏观经济模型（CQMM）秋季预测发布会。报告认为，2013年上半年外部市场需求的萎缩以及近3年来过度投资所引发的产能过剩，使中国工业生产增速和国内生产总值增速持续下降，并双双创下近3年来的最低增长速度。

摘要： In this paper, we propose an economic model predictive control (MPC) framework with a self-tuning terminal weight, which builds on a recently proposed MPC algorithm with.a generalized terminal state constraint. First, given a general time-varying terminal weight, we derive an upper bound on the closed-loop average performance which depends on the limit value of the predicted terminal state. After that, we derive conditions for a self-tuning terminal weight such that bounds for this limit value can be obtained. Finally, we propose several update rules for the self-tuning terminal weight and analyze their respective properties. We illustrate our findings with several examples.

关键词： Redistribution   Mobility   Inequality   Structure-Induced Equilibrium  

摘要： In this paper, we set up a three-period stochastic overlapping-generations model to analyze the implications of income inequality and mobility for demand for redistribution and social insurance. We model the size of two different public programs under the welfare state. We investigate bidimensional voting on the tax rates that determine the allocation of government revenues among transfer payments and old-age pensions. We show that the coalitions formed, the resulting political equilibria, and the demand for redistribution crucially depend on the level of income inequality and mobility.

摘要： In this article a synthesis of formal models for the economic interpretation of the precautionary principle is presented, with their virtualities, limitations and measures to overcome them. The concept of precaution has great relevance in environmental regulation in the European Union. On the one hand, and despite the somewhat vague nature of legislation, the interpretation of the precautionary principle has seen recent progress with the development of some economic models and their application. There is, however, a need for a regulatory framework for the implementation of this principle in environmental decision-making, i.e., to clarify concepts and management procedures that are appropriate to the nature of environmental risks. It is therefore important to know the most relevant economic approaches and models with the aim of identifying their contribution to the debate on precaution in the context of environmental risk management and discuss their practical relevance in public decision- making.

关键词： 经济模型   广州   文化产业  

摘要： 近年来,广州市对文化创意产业的投入比重不断加大,2010年投入1.8亿元,在全国仅次于北京和深圳,但创意文化产业的经济产出却处于第二集团的位置,而既往研究中从政策层面入手进行"从政策到政策"的分析,忽视了文化创意产业自身的产业特性。本文从文化创意产业自身具有的内生增长特性出发,借助新经济增长模型,从人力资本、知识和技术外溢等多个内增因素的角度,聚焦广州文化创意产业并提出了相应的建设性意见。

关键词： 二元经济(H—T经济)   再生资源贸易失业  

摘要： 随着全球资源的日渐减少,废物的再回收利用越来越受到重视,再生资源的国际贸易,日益增加,影响逐步扩大。本文以二元经济为例,分析再生资源贸易的决定因素和贸易自由化对经济的影响。具体来说是在哈里斯-托达罗(Harris-Todaro)二元经济框架中导入循环经济活动,利用一般均衡分析法,分析再生资源的贸易对劳动市场和国民福利的效应。文中探讨了完全竞争和工业部门寡占竞争两种场合,得出的结论是,再生资源的贸易自由化有利于减轻劳动力市场的扭曲,在完全竞争的场合它趋向于改善社会福利;在寡占竞争场合,由于存在寡占竞争的扭曲,贸易自由化对社会福利的效应取决于对经济中两种扭曲的矫正程度。
