Abstract In this paper, the relationship between objective knowledge of EU and people's attitudes towards the proposed European Monetary Union (EMU) is analyzed. As a data base, survey data from Eurobarometer 39 (1993) has been employed. First, it is displayed in a cross-country comparison, how the presented knowledge indicator varies between the original 12 EU members. Then the bivariate relationship of the knowledge index with attitudes towards EMU is investigated. In a next step, the robustness of the positive correlation between objective knowledge and attitudes towards EMU is analyzed in a multivariate regression model. As a conclusion, it is argued that a higher level of EU knowledge could influence people's opinion towards further monetary integration positively.
