The opinion polls preceding this referendum show strong variability in the Swedish public opinion over the last four years. In this paper I derive a simple theoretical model and test it empirically to establish the economic factors driving the opinion. I find that an increase in the nominal exchange rate variability makes the opinion more in favor of membership, while the opposite is true for unemployment variability.21 pages253887 bytesapplication/pdfenPublic opinion; referenda; monetary unionReportEconomics
