This work selectively reviews the literature on exchange rate target zones and their theoretical and empirical methodologies and examines whether they can be used to clarify to what extent this type of exchange rate regime could contribute to greater exchange rate stability. We discuss the main contributions of the first and second generations of exchange rate target zone models. In an attempt to reconcile the poor empirical performance of the Krugman model with the reality of exchange rate target zone regimes, this line of research integrates target zones with alternative underlying economic models, such as imperfect credibility, intra‐marginal interventions and sticky price models. It was thus possible to understand the correlations observed between the exchange rate, its fundamentals determinants and the interest rate differential, and to explain the fact that the statistical distribution of the exchange rate is hump shaped rather than U shaped. This implies that the initial emphasis of target zone models on nonlinearities, ‘honeymoon effect’, ‘smooth pasting’ and marginal interventions has vanished. Exchange rate target zones are better described as similar to managed floating regimes with intra‐marginal interventions, with some marginal interventions when the exchange rate reaches the edges of the floating band. 相似文献

This paper studies the effects of international capital market integration on welfare and the speed of adjustment in a two-region endogenous growth model. Monopolistic firms undertake research and development (R&D) to improve their productivity level. National and international knowledge spillovers affect the returns to R&D. The two countries differ with respect to the initial productivity level and R&D capability (which is a proxy for human capital and structural policies). Long-run productivity gaps are determined by the difference in R&D capability. Over time, there is conditional convergence in productivity levels. The speed of convergence is larger with integrated international capital markets than without. Long-run gaps in consumption levels are larger in the former situation than in the latter. Capital market integration harms (benefits) the leading (lagging) region if domestic spillovers are more important than international spillovers and differences in R&D capabilities are small.The authors research is supported by the Royal Netherlands Academy of Arts and Sciences.

The Classical Equations describe output and income in real terms.To use them to analyse aggregate demand, the transactions theydescribe must be monetised. A sum of money equalto the wage bill of the capital goods sector can be shown tobe necessary and sufficient to carry out all transactions, ina process of circulation which also defines an expression forvelocity. When money has intrinsic value, the quantity approachmay hold in the short run but, in the long run, money will beendogenous. In these conditions, the rate of interest will bedetermined by the supply and demand for reserves, but when moneyis purely nominal, only a minimum rate will be fixed, and therate of interest will have to be pegged. The Appendix developsthe Classical Equations and shows that they define an invariableunit of account. 相似文献

In this paper bilateral models formalizing monthly growth of US imports and exports are employed to investigate the potential
of nonlinear relationships linking exchange rate uncertainty and trade growth. Parametric linear and nonlinear as well as
semiparametric time series models are evaluated in terms of fitting and ex ante forecasting. The overall impact of exchange
rate variations on trade growth is found to be weak. In periods of large exchange rate variations, trade growth forecasts
gain from conditioning on volatility. Empirical results support the view that the relationship of interest might be non-linear
and, moreover, lacks homogeneity across countries and imports vs. exports. JEL no. C14, C22, F31, F41 相似文献

This article extends previous literature which examines the determinants of the price impact of block trades on the Australian Stock Exchange. As previous literature suggests that liquidity exhibits intraday patterns, we introduce time of day dummy variables to explore time dependencies in price impact. Following theoretical developments in previous literature, the explanatory power of the bid–ask spread, a lagged cumulative stock return variable and a refined measure of market returns are also examined. The model estimated explains approximately 29 per cent of the variation in price impact. Block trades executed in the first hour of trading experience the greatest price impact, while market conditions, lagged stock returns and bid–ask spreads are positively related to price impact. The bid–ask spread provides most of the explanatory power. This suggests that liquidity is the main driver of price impact. 相似文献

2001年以来,持续的双顺差促使外汇储备量迅速积累,人民币升值压力增大,为了维持人民币汇率的稳定,政府不得不加大货币投放量来回笼外汇市场上过多的外汇。通过建立外汇储备和货币供给量(M1、M2)之间的双对数模型,进行实证分析得出结论:外汇储备的增加确实推动了中国货币供应量的增加,并且外汇储备变动给M1带来的影响大于M2。因此,应适当控制外汇储备规模消除外汇储备超额增长的制度性原因,完善货币政策工具,积极进行金融创新。 相似文献

截至2006年2月我国外汇储备达8536亿美元,超过日本成为世界外汇储备持有量第一大国,其后我国外汇储备也呈不断增长的态势,到2007年3月已达12020.31亿美元.外汇储备的持续增加意味着面临的风险也在持续增加.因此,如何确定合理的外汇储备币种组合成为目前需要迫切研究的课题.本文根据国内外已有研究确定了外汇储备货币结构的影响因素,结合因子分析法,得出了我国外汇储备币种组合的新选择,提出了我国外汇储备货币组合的对策建议. 相似文献

人民币汇率形成机制问题成为近年来国际经济事务中的焦点.中国外汇交易中心2005年5月推出8种外汇交易品种以及引入外币间交易做市商制度,这一举措成为观察、试验做市商制度的序曲.本文研究认为,外汇市场引入做市商制度有利于改善人民币汇率形成机制,但是由于我国外汇市场还不完善,引入做市商制度也会带来一定的成本.为了全面推广做市商制度,多方面配套问题尚待解决. 相似文献

随着汇率波动的加剧,汇率对贸易的影响凸现.古典与新古典主义因所处于固定汇率体制中的金本位时期,所以并未给以汇率以足够的重视;凯恩斯主义在其需求分析的框架中研究汇率,因此其汇率分析也必然带有凯恩斯主义固有的缺陷--缺乏较坚实的微观基础;新国际贸易理论在产业内贸易框架中分析汇率变量.缺乏宏观高度.本文基于浮动汇率前提,试在宏观经济层面寻找国际贸易中汇率变量的微观基础,并给出程式化分析. 相似文献
