[email protected] Abstract This paper analyses the integration of Croatian and the euro area’s industrial production indices in order to see whether Croatia and the euro area form an optimum currency area. More precisely, it is of interest to determine would future Croatian adoption of euro be of benefit to Croatia (of course, once Croatia joins the EU). First, unit root tests are employed, then cointegration analysis and finally Granger causality test. Results indicate that there is no long run relationship between Croatian and the euro area’s industrial production indices. However, Granger causality test shows that in the short run the euro area’s industrial production causes Croatian. But, this is not enough to conclude that Croatia and the euro area form the optimum currency area. Key words : optimum currency areas, integration of economic activity, Croatia JEL classification : E42, F15, F33 157 1. Introduction In a situation when Croatia started with the negotiation process for joining the EU and when it is very likely that Croatia will join the EU in the next decade at latest, it is justifiable to expect that Croatia will introduce euro, since new members do not have the possibility of the “opt out” clause. For that reason it is necessary to examine whether the introduction of euro will be beneficial for Croatia or will it impose unwanted costs. Discussion about common currency areas usually rests on the theory of optimum currency areas, which was created by Mundell (1961) and supplemented by many other authors such as McKinnon (1963), Kenen (1969), Tower and Willett (1976), Tavlas (1993), Bayumi and Eichengreen (1996) and Frankel and Rose (1998).
