The European Union (EU) has moved towards bicameralism, making the codecision procedure its most important mechanism for decision making. To gauge if European Parliament (EP) and Council of Ministers (CM) are equally powerful codecision makers , understanding of the final stage of the procedure...

This paper analyzes the a priori influence of the European Parliament (EP) and the Council of Ministers (CM) on legislation of the European Union adopted under its codecision procedure. In contrast to studies which use conventional power indices, both institutions are assumed to act...

The European Union (EU) has moved towards bicameralism, making the codecision procedure its most important mechanism for decision making. To gauge if European Parliament (EP) and Council of Ministers (CM) are equally powerful "codecision makers", understanding of the final stage of the procedure...

We present a theoretical model of a parliamentary democracy, where party structures, government coalitions and fiscal policies are endogenously determined. The model predicts that, relative to proportional elections, majoritarian elections reduce government spending because they reduce party...

We study a game theoretic model of a parliamentary democracy under proportional representation where `citizen candidates' form parties, voting occurs and governments are formed. We study the coalition governments that emerge as functions of the parties' seat shares, the size of the rents from...

In this paper we present a structural approach to the study of government formation in multi party parliamentary democracies. The approach is based on the estimation of a stochastic bargaining model which we use to investigate the effects of specific institutional features of parliamentary...

We study a game theoretic model of a parliamentary democracy under proportional representation where 'citizen candidates' form parties, voting occurs and governments are formed. We study the coalition governments that emerge as functions of the parties' seat shares, the size of the rents from...

In this article we present an overview of our recent research on the effects of constitutions on coalition governments in parliamentary democracies. Our approach is based on the solution and estimation of a multilateral bargaining model which we use to investigate the consequences of...

We study a game theoretic model of a parliamentary democracy under proportional representation where ideologically motivated citizen groups form parties, voting occurs and governments are formed. We study the coalition governments that emerge as functions of the parties' seat shares, the size of...
