When should Poland enter the euro-zone? : decision making with the ANP

The aticle presents a solution to a real, current and significant problem for Poland. Poland, as a new EU country should join the Economic and Monetary Union - the euro-zone after fulfilling the convergence criteria set by the Maastricht Treaty, as soon as possible. Entering the zone it should gain in many economic, social and political fields. We can therefore look for new opportunities. However, entering the euro-zone is results also in costs and risks. The paper aims to find an alternative which would maximize benefits and opportunities and minimalize costs and risks. The alternatives were developed - early, medium-term and late entry of Poland’s into the euro-zone. The problem was solved by use of Analytical Network Process. Using multiplicative and additive/negative mathematical formulae the conclusions show, without any doubt, that Poland should enter the euro-zone late, that is after 2011
