This paper analyses stability in real multilateral exchange rates in six leading Latin-American economies during the XXth century using a new data set. A univariate approach is complemented by an error-correction model including key fundamentals. Unit-root testing shows a very slow process of...

The purpose of my paper is to empirically explore the validity of the relative version of purchasing power parity (PPP) for nine EU New Member States (NMS) using unit root and panel unit root frameworks. Three periods are considered: the period before NMS joined the EU (1995:01-2004:04), the...

This paper investigates the relationships between country characteristics and the validity of PPP. We use three alternative time series methods to test for the stationarity of real exchange rates for each of the 72 countries over the period from 1976 to 2005. Our result shows that the evidence...

The aim of this article is to provide additional evidence on the fulfilment of the Purchasing Power Parity (PPP) hypothesis in the so-called Mediterranean countries. In order to test for the empirical validity of such a hypothesis, we have applied two types of unit root tests. The first group is...

Recent studies on general equilibrium models with transaction costs show that the dynamics of the real exchange rate are necessarily nonlinear. Our contribution to the literature on nonlinear price adjustment mechanisms is threefold. First, we model the real exchange rate by a Multi-Regime...

Using methods from machine learning - adaptive sequential ridge regression with discount factors - that prevent overfitting in-sample for better and more stable forecasting performance out-of-sample we show that fundamentals from the PPP, UIRP and monetary models consistently improve the...

Amonetary union is classified by several authors as an extreme form of fixed exchange rate arrangement. Analyzing exits from monetary unions is, however, demanding. This paper studies the impact of inflation and interest rate differentials on the nominal exchange rate after leaving a form of peg...

The empirical validation of the purchasing power parity (PPP) theory is generally based on real exchange rates built using consumer price indexes (CPI). The empirical evidence does not generally support the theory and this fact goes under the name of purchasing power parity puzzle. In this paper...

Fama and French (1992) found that beta has little or no ability in explaining cross-sectional variation in stock returns, but those variables such as size and the book-to-market ratio do. Since the time of the original publication of the Fama and French findings, Controversy and intense debate...

Financial data are often assumed to be generated by diffusions. Using recent results of Fan et al. (J Am Stat Assoc, 102:618–631, 2007; J Financ Econometer, 5:321–357, 2007) and a multiple comparisons procedure created by Benjamini and Hochberg (J R Stat Soc Ser B, 59:289–300, 1995), we...
