Ideology and fiscal policy: quasi-experimental evidence from the German States

Is government ideology important for fiscal policy? I study this question with data from all German States over the period 1975-2005. To identify the effect of ideology, I rely on a fuzzy regression discontinuity design. I find that left-wing state governments spend more than state governments with right-wing and mixed ideology. Deficits of left-wing governments are larger than those of right-wing governments but smaller than those of governments with mixed ideology. These results are robust to sensitivity tests.
