汇率涉及庞大数量的商品、投资和服务的国际交换,在各国经济中发挥着举足轻重的作用.由于近年来国际政治局势紧张,经济波动幅度较大,为了获取充足的样本量,文章采用2009-2016年美元与欧元的每日汇率用以构建Vasicek模型,根据估计分析所得的参数估计量寻求利润最优的汇率套利区间.文章分为两个部分进行探讨:第一部分是通过回归分析发现汇率波动服从均值回归趋势;第二部分是基于汇率变动服从均值回归的基础上确定汇率套利区间.同时,借助于最优套利区间的存在得出政策启示,即货币当局在维持外部经济稳定方面应谨慎使用外汇市场干预措施,同时应聚焦外汇市场中投机者情绪并建立汇率稳定与协调机制,减少因情绪剧烈波动从而对政治和经济造成的冲击. 相似文献

The goal of this paper is to test a variant of the monetary exchange rate determination model, described by Obstfeld and Rogoff
(1996), for the Brazilian economy in the recent period. The model starts with the Cagan (The Journal of Political Economy, 66(4):303–328,
1958) money demand, which is complemented by the hypotheses of purchase power parity (PPP) and uncovered interest parity (UIP).
We used monthly data of exchange rate, GDP, interest rate for Brazil, and U.S. interest rate and inflation as proxies for
international variables. We applied cointegration tests to identify a long run relationship among the variables. The estimated
error correction model offers an exchange rate determination model in the short run. Due to potential endogeneity of some
variables, GMM was applied to estimate a long-run model of exchange rate determination. The forecasting results of both estimatives
were compared with a random walk approach. The results point to the existence of a long and short run equilibrium Real/dollar
exchange rate using the structural model, which may be the achievement of this paper. 相似文献

Recent movements in the Trade Weighted Indexes (MI) of Australia's nominal and real exchange rates are documented. The volatility of the nominal rate in the pre-float and post-float periods is examined. Decompositions are made of the most recent depreciations of the Twls into compenents due to depreciations against the United States dollar ($US) and other major currencies. The extent to which the recent changes can be understood as necessary to correct misalignment in the Australian balance of payments is investigated. 相似文献

“汇改”后人民币汇率制度分析 总被引:3,自引:0,他引:3
自2005年7月21日人民币汇率形成机制进行重大改革以来,人民币对美元的基准汇率一直处于单边升值的态势.从宏观经济特征和模型实证分析中可以得出,虽然"汇改"后人民币货币篮子发挥了一定的作用,人民币汇率的灵活性在逐渐增强,但主要还是参考美元汇率来进行调节,属于"软钉住美元的汇率制度". 相似文献

Real exchange rate variance decompositions indicate that only a small fraction of real exchange rate movements can be attributed to changes in the relative price between traded and non-traded goods. This paper argues that those exercises, by ignoring the nature of the shocks behind real exchange rate changes, may be inadequate to measure the relative importance of non-traded goods prices. Instead, it proposes using a structural vector autoregression (SVAR) model to study the effects of shocks to the relative supply and relative demand for non-traded goods on the real exchange rate. The SVAR model is identified via long-run restrictions and is estimated for a group of advanced economies. The results indicate that for some countries, relative supply shocks can be a significant source of real exchange rate fluctuations. 相似文献

Australia is generally held to be a small open economy with a high proportion of commodity exports. It is therefore regarded as a 'price taker' in international markets, and pass-through on exports is expected to be zero. This paper uses the Johansen Multivariate Cointegration technique to estimate the pass-through of exchange rate changes to the destination-currency prices of aggregate Australian exports. The results demonstrate a stable long-run pass-through level of 60 per cent, which refutes the 'small-country' assumption of Australian exporters as price takers. These findings have important implications for Australia's terms of trade and current account deficit 相似文献

We discuss how the welfare ranking of fixed and flexible exchange rate regimes in a New Open Economy Macroeconomics model depends on the interplay between the degree of exchange rate pass‐through and the elasticity of substitution between home and foreign goods. We identify combinations of these two parameters for which flexible and fixed exchange rates are superior with respect to welfare as measured by a representative household's utility level. We estimate the two parameters for six non‐EMU European countries (Czech Republic, Hungary, Poland, Slovakia, Sweden, and the UK) using a heterogeneous dynamic panel approach. 相似文献

Exchange Rate Effects of Central Bank Interventions: An Analysis of Transaction Prices 总被引:1,自引:0,他引:1
The impact of sterilised interventions by the Swiss National Bank on the Swiss franc/U.S. dollar exchange rate is examined for the 1986–94 period. The paper extends results from earlier studies by using the actual prices of interventions. Based on the fact that all Swiss National Bank interventions are announced, our test exploits the informational differences between interventions and customer transactions. A key finding is that only initial interventions matter; customer transactions and subsequent interventions have no influence. 相似文献

In this article we extend previous BMOM results by showing how information about a variance parameter and its relation to regression coefficients produces a rich class of postdata densities for regression parameters. Prediction and model selection techniques are also described. We also discuss the well-documented link between cross-entropy and the average log odds and then use this criterion in an experiment to compare results obtained from BMOM and Bayes approaches using data generated from known models. 相似文献

The purpose of this paper is to investigate the potential role of monetary and real factors in explaining real exchange rate variability in developing countries. For this purpose two indexes of real effective exchange rate variability that measure short-term and long-term variability were constructed for 30 countries. The results obtained, using a generalized least squares procedures on cross section data, indicate that real exchange rate variability has been affected both by real and monetary factors. In particular it was found that more unstable nominal exchange rate policies were reflected in higher real exchange rate instability in the short-run; more unstable domestic credit policies resulted in higher short-term real exchange rate variability; and more unstable external terms of trade also affected positively the degree of real exchange rate instability.

We consider the effect on the degree of exchange rate pass‐through of the exchange rate regime in operation. We test the hypothesis that pass‐through will be lower under a float as firms may be reluctant to pass appreciations or depreciations on to their customers when there is a strong chance that they will be subsequently reversed. Taylor’s hypothesis that pass‐through will be lower in a low‐inflation environment is also considered. Both hypotheses are assessed in relation to the price of manufactured imports into New Zealand and we find that, whereas the shift to a float dramatically lowered the degree of pass‐through, the later shift to a low‐inflation regime has no significant additional effect on the pass‐through relationship. 相似文献

This paper evaluates the response of employment to exchange rate shocks at the industry level for G-7 countries. Using an empirical framework that places little structure on the data, it is found that European industries, at least France and Germany, are much less influenced by exchange rate shocks and much slower to adjust to long-run steady states. The United States, Japan, Canada, the United Kingdom and Italy all appear to adjust more quickly. German and Japanese employment are quite insensitive to exchange rate fluctuations, consistent with previous research on output and markup responses to exchange rates. 相似文献
