货币升值对不同产业就业的影响——对亚洲八国汇率与就业关系的经验分析

为了研究人民币升值可能对中国各产业就业影响,且避免单独研究中国数据所产生的局限性,本文选取八个亚洲主要国家和地区的数据,利用面板数据模型进行实证分析。实证结果显示汇率升值将对制造业的就业产生负效应,而对第三产业的效应为正,按照该结果,人民币升值将会给中国本已严峻的就业形势带来更大的压力。根据中国各产业就业形势的当前状况及发展趋势,解决中国就业问题的根本出路在于大力发展第三产业。

Minimum Quality Standards under Asymmetric Duopoly with Endogenous Quality Ordering: A Note

In this note, we revisit minimum quality standards (MQS) under a vertically differentiated duopoly. We generalize the model in Ronnen (1991) and Valletti (2000) by introducing asymmetry into the fixed cost of quality improvement and by explicitly taking into account the endogeneity of quality ordering. In the generalized model, we show that the results derived by Ronnen (1991) and Valletti (2000) are largely robust.     

Growth,Employment and Taxation with Distortions in the Goods and Labour Market

Abstract. This paper analyses taxation in the presence of distortions in goods and labour markets in an endogenous growth model. The government disposes of capital, labour and consumption taxes. It is shown that the market solution leads to suboptimally low levels of growth and employment. However, available tax instruments are sufficient to attain the first‐best growth path in this economy. The paper further explores the relative distortion of capital and labour taxes. For plausible parametrisations of the model, lowering capital taxes dominate reductions in labour taxes in welfare terms.     

Anticipated Environmental Policy and Transitional Dynamics in an Endogenous Growth Model

This paper makes a new attempt toinvestigate how an anticipatedenvironmental policy governs the transitionaldynamics of an economy when pollutionexternality is taken into account. Themodeling strategy we use is an AK technologyendogenous growth framework with an endogenousleisure-labor choice. It is found that, unlikeinelastic labor supply framework, a rise inpublic abatement expenditure will stimulate thebalanced economic growth rate. It is alsofound that public abatement technology plays animportant role in determining the transitionaladjustment of the economic growth rate inresponse to a pre-announced environmentalpolicy.     

Endogenous Timing in a Mixed Oligopoly with Foreign Competitors: the Linear Demand Case

We introduce foreign private firms into the model of Pal (1998) and investigate the impact of the introduction of foreign private firms on the endogenous timing in a mixed oligopoly in the linear demand case. We find that the public firm chooses to be a follower of all domestic private firms and that the public firm chooses not to be a leader of all foreign private firms, which is in contrast to Matsumura (2003).     

农业自然资源与食物生产的类型迭置分析—以福建省为例

福建省粮食缺口逐年拉大,其它副食品也出现程度不同的短缺信号。在食物短缺的背后隐含着农业自然资源数量的短缺,并且随着人口的增长而日益严重。本文从农业自然资源与食物生产的内在联系入手,尝试对其丰乏程度进行定量的地域划分和迭置分析,进而探索各地域类型的食物发展方向与总体对策。     

农地利用技术创新的类型与模式研究

农地利用技术是一个多层次的体系，它能在扩大耕地面积、提高土地利用率和耕地质量等多方面发挥重要作用。通过对“市场机制自发作用下的技术选择”和“政府引导下的技术选择”两种现实模式的探讨，认为技术创新具有外部性，土地利用更是具有明显的“外溢效应”，加上我国农业比较利益偏低和农地使用权流转市场发育不全带来的农地价格扭曲，常造成市场机制下技术创新的方向与资源稀缺状况不相符合的现象，从而带来资源配置的低效率。因此，适当的政府引导是必要的，也是有效的。     

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.     

Persistence of Shocks to Output in Austria and Theories of Economic Growth

The paper analyzes the degree of output persistence in GDP in order toempirically discriminate between the Solow growth model, the perfect competition endogenous growth model and the imperfect competition endogenous growth model for the case of Austria. Wefind that a shock in the growth rate of output induces a permanent and larger effect on the level of GDP. This leads us to refute the Solow growth model and the perfect competition model of endogenous growth.We may not reject the imperfect competition growth model.
