The paper proposes a unified framework to study the dynamics of net foreign assets and exchange rate movements. We show that deteriorations in a country's net exports or net foreign asset position have to be matched either by future net export growth (trade adjustment channel) or by future...

In recent years two classes of switching models have been proposed, the Markov switching models, Hamilton (1989) and the Threshold Auto- Regressive Models (TAR), Lim and Tong (1980). These two models have the advantage of being able to modelize and capture asymmetry, sudden changes and...

Using Granger (1969), Sim (1972) and Geweke et al. (1982) causality tests, this study finds a feedback causal relationship between exchange rate and stock price in Malaysia, whereas a unidirectional causal relationship running from exchange rate to stock price in Thailand. The stock markets of...

This study tests weak and semi-strong form efficiency of the foreign exchange market in Sri Lanka using six bilateral foreign exchange rates during the recent float. Weak-form efficiency is examined using unit root tests while semi-strong form efficiency is tested using co- integration and...

This paper examines the empirical validity of purchasing power parity (PPP) hypothesis in a Sri Lankan context using exchange rates for six foreign currencies during the period January 1986 to November 2000. Both graphical and econometric methods are used in the analysis. Graphical analysis...

It has been twenty years since Frankel (1979) offered the classic empirical support for the Dornbusch (1976) overshooting model against the simple monetary approach model, and almost that long since Driskill and Sheffrin (1981) uncovered some important inconsistencies between Frankel’s...

We use a dynamic heterogeneous panel model to estimate real equilibrium exchange rates for advanced transition countries. Our method is based on out-of-sample estimations from middle-income and high-income countries, and we use a pooled mean group estimator. We find that exchange rates have...

This paper examines the validity of the efficient market hypothesis (EMH) for the foreign exchange market of Papua New Guinea (PNG) using data on spot exchange rates for four major foreign currencies during the recent float. The unit root test results indicate that all the four exchange rates...

The paper develops a three-asset-portfolio model to analyse consequences of foreign exchange market operations by Asian central banks on the exchange rates between euro, dollar and yen. Both an analytical as well as a graphical solution is presented. It is found that -- contrary to public belief...

In this paper we investigate in detail the relationship between models of cointegration between the current spot exchange rate, st, and the current forward rate, ft, and models of cointegration between the future spot rate, st+1, and ft and the implications of this relationship for tests of the...
