A. Lupia et K. Strom, COALITION TERMINATION AND THE STRATEGIC TIMING OF PARLIAMENTARY ELECTIONS, The American political science review, 89(3), 1995, pp. 648-665
Cabinet coalitions in multiparty parliamentary democracies lead a prec
arious existence. Legislative majorities can typically dismiss the cab
inet at will and can sometimes force early elections through parliamen
tary dissolution. Since coalition termination can have substantial pol
itical consequences, it is important to understand when and why such d
ecisions are made. To this end, we develop a model of coalition bargai
ning in a legislature with dismissal and dissolution powers. We use th
e model to identify necessary and sufficient conditions for both coali
tion termination and parliamentary dissolution. In contrast to several
widely held maxims, we find that coalition terminations need not be t
he automatic consequence of exogenous shocks. Nor do opportunistic par
ties with favorable electoral prospects always dissolve parliament to
enhance their power. Instead, decisions to terminate coalitions or cal
l new elections result from party leaders' rational responses to the c
onstraints of legislative and electoral institutions and the anticipat
ed feelings of the electorate.
