汇率决定理论的新近发展:文献综述

传统汇率决定理论对于现实经济中汇率实际变动情况的解释能力十分低下.20世纪80年代以来,学术界不断寻求突破,以期为汇率如何决定这一基本命题提供更为合理的解释.在这一过程中,不断有新的文献出现,从不同的方面对传统的汇率理论进行补充、发展和替代.鉴于此,本文试图对汇率决定理论的新近发展进行梳理和介绍,借以为国内经济学界研究汇率决定问题提供一个理论参考.     

Preferences in the Future

Environmental economics has been much occupied with the discount rate, which is the value of future costs and benefits relative to present costsor benefits. But at least as important is the question of whatshould be discounted, that is, what the value of those future environmentalbenefits is to future generations. This paper analyzes the role for futurepreferences and discusses the state of knowledge. I argue that theappropriate discount rate is the market one, and that the real problemis determining future willingness-to-pay. This approach makes clearerthe connection between discounting and the valuation debate.This paper focuses on two features that have been prominent in that debate:existence value and reference dependence. I argue that thereis a vital connection between the two constructs and that this link yieldsimportant implications for future willingness-to-pay.

我国封闭式基金折价与基金运行绩效的相关性检验

笔者以我国的封闭式基金为样本,利用面板数据建模,综合考量了基金折价率与基金绩效指标间相关关系.研究结果发现,基金绩效指标对当期折价指标有显著的负的影响;而当期的基金折价指标不能准确预测未来绩效水平,即基金折价率并没有提供对未来基金绩效的有价值信息.     

The Real Equilibrium South African Rand/US Dollar Exchange Rate: A Comparison of Alternative Measures

This article indicates how different measures of the real exchange rate, i.e., the exchange rate adapted for cost inflation, price inflation and labour costs, influence the equilibrium view and misalignment of the South African rand/US dollar exchange rate. The approach followed is based on the behavioural equilibrium exchange rate approach by Clark and MacDonald (1998), where the exchange rate is influenced by a number of fundamental and transitory factors. The real equilibrium exchange is estimated by using a single equation regression and a number of key explanatory variables. To determine the long-run relationship a Vector Error Correction Mechanism is used.     

The long-run effects of the real exchange rate on employment and wages in Canadian manufacturing

ABSTRACT

The literature on real exchange rate effects on the labour market is dominated by short-run analysis showing that there is heterogeneity in the responses of firms or industries to a real exchange rate shock. Analysing data on Canadian manufacturing industries, I conclude that there is a common long-run equilibrium across all manufacturing industries controlling for their openness to trade after varying adjustments to a real exchange rate shock have taken place. This conclusion is important from the perspective of policy making because it helps to form expectations about the effects of a real exchange rate movement on the labour market. The results suggest that real appreciation leads to economically significant reductions in employment in manufacturing in the long run. Real wages decrease in industries that are highly engaged in international trade and somewhat increase in industries that are relatively closed to international trade. Both employment and real wages converge quickly to the long-run equilibrium.     

On wage- and profit-led demand regimes: learning from the evidence

Abstract

This paper contributes to the empirical research around the “wage-led” or “profit-led” demand regimes. It first reviews how Kalecki, and then Steindl, approached the relationship between economic growth and income distribution. Then, empirical analysis carried out under the probabilistic approach to econometric modeling shows statistical evidence, estimated through cointegration analysis, that in the long run, in three very open economies—Mexico, France, and Korea—the wage share is positively associated with demand and output. It finally discusses the macroeconomic dilemma that almost all countries have to face, i.e., a positive effect of a high-wage policy on demand and employment may diverge from a negative effect on output compatible with external equilibrium.     

北京的经济发展及其增长因素分析

建国以来，北京经济的发展发生了巨大的变化。对于经济增长的因素，主要表现在劳动力数量增加的变化和技术退步等方面。经济发展由资本和劳动力数量的增大等外延的发展形态转换为内涵的发展状态，即劳动力素质的改善、技术的追步以及资本集约度的上升等作为积极因素促进经济的增长。

货币政策的粘性均衡汇率效应模型及人民币汇率定价的弹性分析

本文以开放的宏观经济为框架、以厂商利润最大化为微观经济基础、以严格的数学推导为逻辑纽带、以粘性价格为理论依据、以购买力平价的微分冲击形式为理论基础，提出并构建了两国货币政策的粘性均衡汇率效应模型。应用模型，本文对1992～2002年的人民币粘性均衡汇率进行了定价，并对2003年的定价进行了预测。以定价汇率及其预测为标准，对1992～2003年的人民币汇率偏离与经常性项目的关系，进行了弹性分析。根据模型与实证分析，获得了一些重要结论。
