Exchange rate, inflation and unemployment in East European economies: the case of Poland and Hungary*

The aim of the paper is to model the impact of exchange rate on both inflation and unemployment variables in economies which are characterized by important structural changes, i.e. a transition phase moving from centralized economies towards market economies. This phenomenon, which is common to the East European countries, stressed different effects both for what concerns the behaviour of economic agents and for what concerns fiscal and monetary measures adopted by governments and aiming to keep under control the inflation–unemployment trade off. Time series relationships between these variables are investigated within an econometric model. Economic theory and the available data on the hypothetically relevant variables, along with the consideration of the main facts occurred in the period under study, characterize our information set. It is found that single equation analysis yields inefficient inference relative to the whole system analysis, and important structural changes are detected which reflect possible breaks in the structure of the economic system along with a change in economic policy.
