under coalition governments. And heterogeneity of political districts should influ-
ence government spending, as well as political outcomes, but only under plurality
rule. Moreover, we have confined the theoretical and empirical analysis to the
overall size of government spending. But the crucial difference between coalition
and single-party governments emphasized in this paper is likely to influence other
economic policy dimensions, such as the size of budget deficits or the composition
of spending and taxation. We leave these promising and exciting topics for future
research.
