How rational are voters when expecting government parties to fulfil pledges? A cross-national survey experiment

That parties fulfil their pre-election pledges once they are in government is a fundamental idea of many democracy models. This paper addresses the question of whether the government/opposition status of their party affects how much citizens want governments to fulfil their promises. We hypothesize that interest-driven, rational voters are more likely to prefer their own party to keep its promises and investigate whether this rationale is impacted by public opinion and expert views. The analysis is based on a survey experiment conducted in Australia and Austria. It finds that voters broadly adhere to the democratic principle of expecting pledge fulfilment but, at the same time, some take a rational approach to government promises. The opinions of the public and experts mitigate but do not change this effect. Another key finding is the significant difference in the preference for promise keeping versus promise breaking between government and opposition voters in the Austrian case, the country with the more heterogeneous and polarized political system. This paper contributes to the literature on voters' attitudes on democracy and pledge fulfilment by showing that voters are normatively driven but a significant number of voters deviate and instead follow the rational voter logic.
