Owner-occupied housing in a model of exchange rate determination

This study explores the effect of owner-occupied housing asset holdings on the short and long run determination of exchange rates. In the presence of consumption goods that can simultaneously serve as investment allocation subject to capital gains—such as owner-occupied housing—the general equilibrium model, based on the Obstfeld and Rogoff Redux model, produces exchange rate overshooting both in the presence and in the absence of price rigidities in the markets for final goods. This effect depends on the size of owner-occupied housing expenditures relative to total consumption expenditures, the initial level of housing market inflation, capital gains in housing and other parameters of the model. Depending on parameter values and initial conditions, the model supports the possibility for exchange rate dynamics that include either overshooting or undershooting.     

News effects in a high-frequency model of the sterling-dollar exchange rate

This paper uses an extremely high frequency data set on the dollar-sterllng exchange rate to investigate the impact of news events on the very short-term movements in exchange rates. The data set is a continuous record of the quoted price for the exchange rate on the Reuters screen. As such it records some 130,000 observations over an 8-week period. The paper investigates the time-series properties of the data using orthodox regression models, and then by making allowance for a time-varying conditional variance. The conclusions vary significantly in moving to this more sophisticated model. The exercises are repeated now incorporating news announcement effects, letting these affect the level of the exchange rate and then the conditional variance process. Again it is found that the conclusions are radically altered in moving to the increasingly sophisticated model.

An empirical investigation into the causes of failure of the monetary model of the exchange rate

The purpose of this paper is to attempt to provide measures of the relative importance of the principal causes of the failure of the monetary model of the exchange rate. Secondly, the random walk hypothesis for the exchange rate is tested. The methodology employed is new and has wide application elsewhere. It involves explicitly modelling the misspecification by time series techniques. The results confirm the importance of the breakdown of the PPP assumption but they also show that misspecification of the money market is equally important. The results further show that lagged information can also improve upon the random walk model of the exchange rate.     

A note on transfer prices and exchange rate pass-through

The paper builds a model of a parent corporation selling an intermediate product to a foreign subsidiary. The model is used to explain the response of foreign prices to changes in the exchange rate between the country of the parent affiliate and the foreign subsidiary. The model examines this response with and without an external market for the intermediate product.     

Analysis on the exchange rate of Australian dollar

Australian dollar （AUD） maintains a fluctuant increase for long period, but in recent two years, this currency represents an anomalistic change. In order to forecast the trend of AUD, this essay examines the exchange rate of AUD in then years from March of 2000 to March of 2010, and argues the factors which create these trend changes. By means of secondary research and graphs analysis, the relevant evidence and argument was selected into four terms below： relative raw materials prices changes, relative domestic price level and Import-Expert changes, relative interest rate changes, and other factors. The examples based on the theoretics, graphs, statistics and experts＇ opinions.     

A semiparametric GARCH model for foreign exchange volatility

A semiparametric extension of the GJR model (Glosten et al., 1993. Journal of Finance 48, 1779–1801) is proposed for the volatility of foreign exchange returns. Under reasonable assumptions, asymptotic normal distributions are established for the estimators of the model, corroborated by simulation results. When applied to the Deutsche Mark/US Dollar and the Deutsche Mark/British Pound daily returns data, the semiparametric volatility model outperforms the GJR model as well as the more commonly used GARCH(1,1) model in terms of goodness-of-fit, and forecasting, by correcting overgrowth in volatility.     

Testing the forward volatility unbiasedness hypothesis in exchange rates under long-range dependence

This paper analyses the unbiasedness hypothesis between spot and forward volatility, using both the actual and the continuous path of realised volatility, and focusing on long-memory properties. For this purpose, we use daily realised volatility with jumps for the USD/EUR exchange rate negotiated in the FX market and employ fractional integration and cointegration techniques. Both series have long-range dependence, and so does the error correction term of their long-run relationship. Hence, deviations from equilibrium are highly persistent, and the effects of shocks affecting the long-run relationship dissipate very slowly. While for long-term contracts, there is some empirical evidence that the forward volatility unbiasedness hypothesis does not hold – and, thus, that forward implied volatility is a systematically downward-biased predictor of future spot volatility – for short-term contracts, the evidence is mixed.     

Unit root and cointegration tests on the efficiency and biasedness of forward exchange rates

This paper analyzes the stationarity of spot and forward exchange rates by testing for the presence of unit roots in the autoregressive process of the exchange rate time series. The results of the unit root and cointegration tests for forward exchange rates of six major currencies are inconsistent with earlier studies by others that found the existence of unit roots but the absence of cointegration. Our results show that realized spot rates are cointegrated with past forward rates. Both Dickey-Fuller and Augmented Dickey-Fuller tests affirm the unbiased forward rate hypothesis for 30- and 90-day forward rates. The Augmented Dickey-Fuller tests on the longer term forward rate, however, reveal the existence of cointegration that leads to the rejection of the hypothesis.     

The real exchange rate and the structure of aggregate production

This paper proposes a new, production theory approach to the determination of the real exchange rate, which is defined as the relative price of traded to nontraded goods as is common in the international trade literature. Using a Translog real GDI function that describes the aggregate technology of an open economy as a starting point, the real exchange rate can be formally derived as a function of domestic excess savings, the terms of trade, relative factor endowments and technological progress. Empirical results for Switzerland suggest that the main drivers of the real exchange rate are the terms of trade, followed by relative factor endowments. Contrary to conventional wisdom, the Balassa-Samuelson effect does not seem to play a significant role in explaining the long-term real appreciation of the Swiss franc.     

Bayesian Model Averaging and exchange rate forecasts

Exchange rate forecasting is hard and the seminal result of Meese and Rogoff [Meese, R., Rogoff, K., 1983. Empirical exchange rate models of the seventies: Do they fit out of sample? Journal of International Economics 14, 3–24] that the exchange rate is well approximated by a driftless random walk, at least for prediction purposes, still stands despite much effort at constructing other forecasting models. However, in several other macro and financial forecasting applications, researchers in recent years have considered methods for forecasting that effectively combine the information in a large number of time series. In this paper, I apply one such method for pooling forecasts from several different models, Bayesian Model Averaging, to the problem of pseudo out-of-sample exchange rate predictions. For most currency–horizon pairs, the Bayesian Model Averaging forecasts using a sufficiently high degree of shrinkage, give slightly smaller out-of-sample mean square prediction error than the random walk benchmark. The forecasts generated by this model averaging methodology are however very close to, but not identical to, those from the random walk forecast.     

The limiting distribution of extremal exchange rate returns

Several nonnested fat-tailed distributions have been advocated for modelling exchange rate returns. Instead of directly estimating these nonnested distributions we investigate the extremal distribution of the returns. The advantage is that the parameter which characterizes the amount of tail fatness can be estimated without maintaining a specific distribution, and hence enables one to test hypotheses. The parameter of the limit law is estimated by employing nonparametric procedures based on order statistics. The appropriateness of these procedures is assessed. Given this estimate one can derive bounds on the returns for very low probabilities on an excess. Such information is useful in evaluating the volatility of exchange rates.     

A dynamic equilibrium model of search, production, and exchange

We study a general equilibrium model where agents search for production and trading opportunities, that generalizes the existing literature by considering a large number of differentiated commodities and agents with idiosyncratic tastes. Thus, agents must choose nontrivial exchange as well as production strategies. We consider decreasing, constant, and increasing returns to scale in the matching technology, and characterize the circumstances under which there exist multiple steady state equilibria, or multiple dynamic equilibria for given initial conditions. We also characterize the existence of dynamic equilibria that are limit cycles. Equilibria are not generally optimal, and when multiple equilibria coexist they may be ranked. We analyze comparative statics and find that certain intuitive results do not necessarily hold without restrictions on the stochastic structure.     

人民币汇率:缓解升值压力,加快制度改革

近一段时间人民币汇率在内外因的共同作用下升值压力巨大,盯住美元的固定汇率制度已经不符合当前中国的经济形势,但是完全放开人民币汇率让其自由浮动在现有条件下也是行不通的,以市场供求为基础的有管理的浮动汇率制度才是目前的最佳选择。     

The exchange rate pass-through in the new EU member states

This paper aims to complete our understanding of the relationship between changes in nominal effective exchange rates and prices in the new EU member states. I investigate the exchange rate pass-through to import, producer and consumer prices for ten Central and Eastern European countries with quarterly data from January 1996 to December 2011. In a first step, the pass-through estimates are derived from a dynamic panel data model through the generalized method of moments. A statistically significant exchange rate pass-through to consumer, producer and import prices is found, both in the short and long run. In a second step, I proceed to an individual analysis, country by country, and find support for an increased heterogeneity in the exchange rate pass-through estimates. In a third step, I assess the drivers of the estimated exchange rate pass-through coefficients and find support for a significant impact of exchange rate volatility, inflation volatility, import dependence, and the output gap, as well as the global outlook.     

Asymmetric effects of exchange rate changes on the Malaysia-China commodity trade

Previous research that considered the response of the trade balance between Malaysia and China to exchange rate changes used a linear model and did not find any significant long-run link. Suspecting that the results suffer from aggregation bias as well as ignoring nonlinear adjustment of the exchange rate, we consider the trade balance of 59 industries that trade between the two countries and use a nonlinear ARDL model to show that almost a third of the industries are affected by ringgit depreciation against the yuan, in an asymmetric manner. The largest industry, which accounts for more than 25% of the trade, is found to benefit from ringgit depreciation while not being hurt by appreciation. In total, 15 industries that account for 40% of the trade enjoy this property.
