Economic, political and institutional determinants of budget deficits in the European Union

Using an extended data set of EU countries ranging from 1971-2006 and relevant econometric methods, we investigate the economic, political, and institutional determinants of government deficits in the EU. The results show a strong opportunistic behaviour of policymakers which leads to political business cycles. We find that political fragmentation does not play a significant role in government deficits. Partisan behaviour has a weak effect. The stability of the government has a significant negative impact on the size of the budget deficit. The paper also shows the significant effects of the Maastricht Treaty on fiscal consolidation.
