Why dominant governing political parties are cross-nationally influential
Previous research suggests that political parties learn from and emulate the successful election strategies of governing parties in other countries. But what explains variation in the degree of influence that governing parties have on their foreign counterparts? We argue that clarity of responsibility within government, or the concentration of executive responsibility in the hands of a dominant governing party, allows parties to learn from the most obviously electorally successful incumbents. It therefore enhances the cross-national diffusion of party programs.
