Export diversification and real exchange rate in emerging Latin America and Asia: A South–North vs. South-South decomposition

The present paper examines the directional causality between export diversification and real exchange rate in the middle-income countries of Asia and Latin America over the period from 1995 to 2013. Additionally, we investigate asymmetries in the causality issue by examining the direction across trading partners.

Our empirical results show that there is a two-way causality between the two variables when we look at the sample as a whole. A causal link running from the real exchange rate to export diversification is consistent with the standard literature but it is not systematic at all. The reverse causation is very appealing and challenges the standard argument on exchange rate determination. When the causality issue is investigated by treating export markets differently, our findings at the aggregate level are confirmed in exports destined for the advanced countries. The analysis for ‘South-South’ trade only shows a unidirectional link from the real exchange rate to changes in export diversification. The same tests performed at the individual countries level reveal a heterogeneous causality across trading partners.     

国际资本流动对我国就业影响的均衡分析

文章通过建立一个劳动力市场与资本市场的均衡模型,对国际资本不流动与国际资本不完全自由流动两种情况下的分析表明,国际资本流动加剧了国内劳动力市场的就业风险,并且国际资本流动对就业水平影响与本国资本市场的开放度有关,增加开放度有利于提高本国的就业水平.我国应在采取有效措施减小国内劳动者就业波动的同时,逐渐提高资本市场的开放度.     

DIFFUSION MODELS FOR EXCHANGE RATES IN A TARGET ZONE

We present two analytically tractable diffusion models for an exchange rate in a target zone. One model generalizes a model proposed by De Jong, Drost, and Werker (2001) to allow asymmetry between the currencies which is often an important feature of data. Estimation of the model parameters by the method of Kessler and Sørensen (1999) using eigenfunctions of the generator is investigated and shown to give well-behaved estimators that are easy to calculate. The method is well suited to the models because the eigenfunctions are known so that explicit estimating functions are obtained, and because the state space is a finite interval, for which it is known that the method can be made arbitrarily efficient by including sufficiently many eigenfunctions. The model fits data on exchange rates in the European Monetary System well. In particular, the asymmetry parameter is significantly different from zero for three out of four currencies. An alternative diffusion model is presented with similarly nice properties, but with different dynamics that allow constant volatility near the boundaries of the target zone. No-arbitrage pricing of derivative assets is considered, and the effect of realignments is briefly discussed.     

The combined effects of dependence and relationalism on the use of influence in marketing distribution systems

This study uses data from the automotive replacement tire industry to test the proposition that dependence and relationship structure interact to determine frequency of influence-strategy use in distribution systems. The findings support the expectation that dependence is positively associated with recommendations, information exchanges, promises, requests, legal pleas, and threats. However, increases in dealer dependence increase the use of requests, legal pleas, and threats only in systems characterized by trivial levels of relationalism.The authors would like to express their gratitude to John Burnett, Robert Dwyer, Jule Gassenheimer, and Allen Wilhite for their helpful comments on this project.     

The market microstructure of central bank intervention

How quickly do central bank intervention operations impact the foreign exchange market? And, do intra-daily market conditions influence the effectiveness of central bank interventions? This paper uses high-frequency intra-daily data to examine the relationship between the efficacy of intervention operations and the “state of the market” at the moment that the operation is made public. The results indicate that some traders typically know that the Fed is intervening at least 1 h prior to the public release of the information in newswire reports. Also, the evidence suggests that the timing of intervention operations matters—interventions that occur during heavy trading volume, that are closely timed to scheduled macro announcements, and that are coordinated with another central bank are the most likely to have large effects.     

我国纺织品出口对经济增长贡献的实证研究

出口贸易是影响经济增长的重要因素。本文采用1980-2004年的数据,描述了我国纺织品出口的特点,并借助协整模型实证研究了纺织品出口对经济增长的影响,指出二者之间存在长期的动态关系。通过定量分析,发现纺织品出口对经济增长的直接拉动度和贡献率都较低,这是因为我国纺织服装行业一方面受宏观环境影响,另一方面自身竞争优势不足。本文经过研究,形成了对我国纺织品出口与经济增长之间关系直观而清晰的认识,并为无配额时代我国纺织业发展的后续研究提供了参考。     

人民币实际汇率与贸易条件的实证研究

基于均衡汇率理论,应用协整模型,采用真实变量分析了1980-2003年的人民币实际汇率及其与均衡汇率的失调情况,进而研究了不同时期人民币实际汇率与贸易条件的关系。结果表明:贸易条件与中长期以及短期的实际汇率存在显著的关系,贸易条件的恶化或改善是导致人民币实际汇率升值或贬值的重要原因之一。并且,在不同的发展时期,贸易条件对实际汇率的影响呈现出不同的特点。
