This paper presents a validation framework for collateral requirements or margins on a derivatives exchange. It can be used by investors, risk managers, and regulators to check the accuracy of a margining system. The statistical tests presented in this study are based either on the number,...

This article examines the volatility dependence between the crude oil price and four US dollar exchange rates using both fractional cointegration and copula techniques. The former exploits the long memory behavior of the volatility processes to investigate whether they are tied through a common...

In this paper we investigate the impact of financial globalization on the behaviour of inflation targeting emerging market economies with respect to exchange rate - do central banks respond to exchange rate movements or not. We use quarterly data for six emerging market inflation targeting...

Recent literature suggests that a proactive exchange rate policy in accordance with price incentives (i.e. undervaluation) can foster manufactured exports and growth. This paper is built on these recent developments and investigates, using a sample of 52 developing countries, whether such a...

In this article, we examine the intradaily Euro-dollar exchange rate volatility persistence result from the dissymmetric impact of monetary policy signals stemming from the ECB Council and the FOMC. A model is constructed by extending the AR(1)-GARCH (1,1) to an exponential process EGARCH (1,1),...

In this paper we study, using the sup LR test, the possibility of discrimination between two classes of models: the Markov switching models of Hamilton (1989) and the Threshold Auto-Regressive Models (TAR) of Lim and Tong (1980). This work is motivated by the fact that generally practicians use,...

Foreign exchange rate plays an important role in international finance. This paper examines unit roots and the long range dependence of 23 foreign exchange rates using Robinson's (1994) test, which is one of the most efficient tests when testing fractional orders of seasonal/cyclical long memory...

Recent literature suggests that a proactive strategy consisting of deliberate real exchange rate depreciation can promote exports diversification and growth. This paper is built on these recent developments and investigates whether four developing countries have adopted such a strategy. Data...

This paper argues that, for a given average level of income per capita, the real currency depreciation has a negative impact on child survival, due to higher relative prices of tradable goods such as food and drug. This assumption is significantly tested from a dynamic panel model covering about...

Trade deficits and surpluses are sometimes attributed to intentionally low or high exchange rate levels. The impact of exchange rate levels on trade has been much debated but the large body of existing empirical literature does not suggest an unequivocally clear picture of the trade impacts of...
