Nonlinear deterministic forecasting of daily dollar exchange rates

We perform out-of-sample predictions on several dollar exchange rate returns by using time-delay embedding techniques and a local linear predictor. We compared our predictions with those by a mean value predictor. Some of our predictions of the exchange rate returns outperform the predictions of the same series by the mean value predictor. However, these improvements were not statistically significant. Another interesting result in this paper which was obtained by using a recently developed technique of nonlinear dynamics is that all exchange rate return series we tested have a very high embedding dimension. Additionally, evidence indicates that these series are likely generated by high dimensional systems with measurement noise or by high dimensional nonlinear stochastic systems, that is, nonlinear deterministic systems with dynamic noise.     

Catching up: The role of demand, supply and regulated price effects on the real exchange rates of four accession countries

The main aim of this paper is to examine the exchange rate behaviour of a group of four transitional, EU accession countries, with a view to making policy recommendations regarding their full accession to the European Monetary Union. We employ a dynamic OLS panel estimator to investigate the relative importance of demand and supply influences on the exchange rates of these countries. Our analysis shows that both supply‐ and demand‐side effects are important for the accession countries, although their overall effect on inflation differentials and competitiveness seems to be small. An additional focus of the paper is the examination of the role that administrated, or regulated, prices and the productivity of the distribution sector play in the real exchange rate dynamics. Using a unique database we show that administrative prices have been a powerful force behind price and real exchange developments for our group of accession countries. The distribution sector is shown to have an independent effect on the internal price ratio over and above that generated by the Balassa–Samuelson effect.

The coordination of regional interest in developing river basin

1. IntroductionRiver basin is a typical natural region andcatchments of rivers or water systems, which takes ariver as its central line and is surrounded by dividingwater line, and it is an independent, self-systemic hy-drology unit from source to mouth of river with spe-cific scope in region. River basin is a special kind ofregion, in which all-natural factors have close relationwith each other and there is remarkable influence be-tween inter-regions, especially between upper andlower reaches…
