基于钻石模型的福建省生态农业竞争力研究

本文尝试运用钻石模型剖析福建省生态农业的竞争力,并在此基础上结合灰色关联度分析法对福建省与其他华东诸省生态农业的竞争力进行比较,研究结果显示：相对而言,福建省生态农业的总体竞争力水平较低,仅在高级生产要素及机遇方面具有一定优势,我们应从优化生产要素、拉动需求和拓宽政策导向等方面来提升福建省生态农业竞争力。

Optimal Intervention Policies for a Small Monetary Economy

We analyze the gains from trade for a small cash-in-advance economy with endogenous labor supply and learning-by-doing in the accumulation of human capital. Contrary to previous findings, we show that free trade is not optimal independently of the relative amount of cash required for the purchase of each good. Furthermore, a monetary rule à la Friedman can eliminate distortions deriving from the cash-in-advance constraint only under segmented financial markets; in any case, it cannot restore the economic optimum. Finally, we identify government intervention policies, such as wage and export subsidies, that can be welfare improving.     

Learning of cycles and sunspot equilibria by Genetic Algorithms

We analyze the learning behaviour of a Simple Genetic Algorithm in an overlapping generations model with one consumption good and fiat money. It is shown by simulations, that in cases where periodic equilibria exist the equilibrium of period two is learned by a Genetic Algorithm and not the monetary steady state. We further show that proper coding leads to convergence of the GA towards the sunspot equilibrium. If individuals who believe in the impact of sunspots are brought together with individuals who ignore the sunspots, the sunspot believes will in most cases drive the other individuals out of the population.     

How to invest over the life cycle: Insights from theory

We analyse the state of the art in the field of life cycle portfolio choice, a recent strand of the literature on intertemporal portfolio selection. Life cycle models are designed to identify optimal savings and portfolio policies over the lifetime of investors. They can help to improve pension schemes by showing how these could be specifically tailored to the individual employee’s circumstances to overcome the ‘one-size-fits-all’ philosophy still prevailing in parts of the mandatory retirement savings system. To facilitate comparison, we first describe set-up, solution method and characteristic results for a basic model and then derive a general framework to classify existing contributions. We highlight the models’ strengths and weaknesses and assess their ability to resolve existing portfolio puzzles. Lessons from the literature are summarized and promising areas for further research identified. JEL classifications G11, D14, D91, H55     

对蒙代尔-弗莱明模型的修正--中国经济增长对人民币汇率作用机制

蒙代尔-弗菜明模型认为，经济增长会使一国经常账户恶化从而导致本国货币贬值，中国自1994年以来经济快速增长，而经常账户却是持续顺差，在利率不断下降条件下，资金大量流入，人民币汇率稳中有升，外汇储备大幅度增加，这些显然有悖于蒙代尔-弗菜明模型。本文认为，购买力平价理论更符合中国现实，并给出了购买力平价理论动态表述，然后对传统的汇率货币模型进行修正，进一步分析经济增长与汇率之间关系。最后本文对蒙代尔-弗莱明模型国际收支平衡线进行修正，并运用修正后的M-F模型分析在开放经济条件下的财政政策与货币政策效果。
