This study aims to test the efficiency of the Korean foreign exchange market and examine its determinants through several well-established methodologies based on the forward rate unbiasedness hypothesis and covered interest rate parity. The empirical findings indicate that the currency market...

In the United States, Japan and the Euro Zone, FX interventions are institutionally decided by specific political authorities and implemented by central banks on their behalf. Bearing in mind that these specific political authorities and central banks might not necessarily pursue the same...

This paper generalizes central banks’ FX interventions reaction functions to include oral interventions alongside actual ones. Using Japanese data for the 1991-2004 period, we estimate an ordered probit explaining the occurrence of each type of intervention and evaluating the extent to which...

The aim of the paper is to verify whether the USD/EUR exchange rate market is efficient. The fundamental parity condition for testing foreign exchange market efficiency is represented by the uncovered interest-rate parity (UIP). Therefore, the UIP hypothesis verification accounts for the crucial...
