En este documento se analizan los determinantes de la frecuencia de intervenciÛn del Banco Central de Reserva en el mercado cambiario Peruano (compras y ventas). Se usan datos en frecuencia semanal para el periodo Enero 2001 hasta Diciembre 2010 usando la metodologia de modelos de conteo. Los...

The objective of this study is to examine the impact of exchange rate on Nigeria’s trade balance. Time series data on trade balance, external reserves, exchange rate, money supply and real GDP were used in the analysis and the data were subjected to unit root tests to determine their time...

The exchange rate plays an important role in a country’s export performance and currency volatility has impact on international trade, the balance of payments and economic performance, however, views on the impact of exchange rate volatility on international trade flows are inconsistent, thus...

This paper examines the presence of nonlinear mechanism in the exchange rate pass-through (ERPT) to CPI inflation for 12 euro area (EA) countries. Using logistic smooth transition models, we explore the existence of nonlinearity with respect to economic activity along the business cycle. Our...

This paper investigates whether the exchange rate pass-through (ERPT) to CPI inflation is a nonlinear phenomenon for five heavily indebted euro area (EA) countries, namely the so-called GIIPS group (Greece, Ireland, Italy, Portugal, and Spain). Using logistic smooth transition models, we explore...

We propose a fundamentals-based econometric model for the weekly changes in the euro-dollar rate with the distinctive feature of mixing economic variables quoted at different frequencies. The model obtains good in-sample fit and, more importantly, encouraging outof-sample forecasting results at...

Researchers have encountered difficulties in finding empirical evidence of Purchasing Power Parity (PPP) especially when conventional linear unit root tests are employed for the Japanese yen real exchange rate. Chortareas and Kapetanios (2004), however, report strong evidence in favor of a...

This paper estimates the degree of persistence of 16 long-horizon real exchange rates relative to the US dollar. We use nonparametric operational algorithms by El-Gamal and Ryu (2006) for general nonlinear models based on two statistical notions: the short memory in mean (SMM) and the short...

This paper revisits the empirical evidence of purchasing power parity under the current float by recursive mean adjustment (RMA) proposed by So and Shin (1999). We first report superior power of the RMA-based unit root test in finite samples relative to the conventional augmented Dickey-Fuller...

In this paper we evaluate exchange rate predictability using a framework developed by Giacomini and White (2006). This new framework tests for conditional predictive ability rather than unconditional predictive ability, which has been the standard approach. Using several shrinkage based...
