Abstract:
In this paper we analyse four determinants of turnout in petition referendums. We find that distributive referendums have higher turnout than efficiency referendums; the higher the percentage obtained by parties campaigning for abstention, the lower turnout. Furthermore, referendums held in June show significantly less voters than in other months. The number of referendums voted simultaneously has no effect on turnout up to four referendums. Starting from these results we discuss possible reforms.
