We use a previously unexploited data set to calculate the real exchange rate with respect to the U.S. dollar for Mexico for 1930.01-1960.12, and to test for purchasing power parity (PPP). The initial results from the Augmented Dickey-Fuller (ADF) test show weak support for the PPP hypothesis....

En un escenario como el actual, de continua apreciación nominal del peso colombiano frente al dólar, se hace relevante insistir en el uso de un concepto más amplio, como es la tasa de cambio real (TCR), para examinar las causas de la apreciación y evaluar la competitividad del país. Son...

We investigate the likely sources of exchange rate dynamics in selected CIS countries (Russia, Kazakhstan, Ukraine, Kyrgyzstan, Azerbaijan, and Moldova) over the past decade (1999-2008). The analysis is based on country VAR models augmented by a regional common factor structure (FAVAR model)....

We investigate the likely sources of exchange rate dynamics in selected CIS countries (Russia, Kazakhstan, Ukraine, Kyrgyzstan, Azerbaijan, and Moldova) over the last dec-ade (1999-2010). Evidence is based on country VARs augmented by a regional com-mon factor structure (FAVAR model). The models...

This paper shows that nonlinearity can provide an explanation for the forward exchange rate anomaly (Fama, 1984). Using sterling-Canadian dollar data, and modelling nonlinearity of unspecified form by means of a random field, we find strong evidence of time-wise nonlinearity and, significantly,...

Deciding whether a time series that appears nonstationary is in fact fractionally integrated or subject to structural change is a diffcult task. However, various tests have recently been introduced for distinguishing long memory from level shifts and nonlinearity. In this paper, three testing...

This paper examines the PPP hypothesis analysing the behaviour of the real exchange rates vis-à-vis the US dollar for four major currencies (namely, the Canadian dollar, the euro, the Japanese yen and the British pound). An innovative approach based on fractional integration in a multivariate...

This paper analyses the long-memory properties of a high-frequency financial time series dataset. It focuses on temporal aggregation and other features of the data, and how they might affect the degree of dependence of the series. Fractional integration or I(d) models are estimated with a...
