Abstract

We examine the Czech Crown/US Dollar exchange rate for evidence of market efficiency during the period May, 1997, to September, 1998. The Czech Crown was floated on the world's foreign exchange markets in May, 1997, and it is of interest to examine the behaviour of this new market. We show that this foreign exchange market satisfied the criteria for weak form efficiency during the first part of the period under investigation but there is evidence of non-linear dependence during the second part of the period. This is successfully modelled using a GARCH-M(1,1) representation.
