Despite years of crisis, the euro is still enjoying strong popular support in many of the Eurozone crisis countries. Given the high costs that the crisis has imposed on these countries, this raises the question why the public is still in favor of the common currency, and under which circumstances these high support levels may decrease. Using original survey data from three consecutive survey waves in Greece (from July, September, and December 2015), we analyze why a comfortable majority of Greeks have still not withdrawn their support for the euro. We use a detailed battery of questions, designed specifically to tap the many explanations given in the literature and public debate for this phenomenon, to tease out the different mechanisms. Using survey experiments, we then specifically focus on the trade-off between keeping the euro and austerity. We find that as individuals learn that austerity is the price for staying in the euro, their support for the common currency weakens, as evidenced both by a marked fall in the support for the euro between July and December 2015 and experimental evidence. Overall, our paper provides an explanation for why political elites so far have been able to commit to painful austerity and reforms: they had a clear mandate to do everything necessary to stay in the euro. Our results suggest, however, that this may change when the costs of austerity become too high, making an exit for the Eurozone a distinct possibility.
