The Good , the Bad and the Populist : A Model of Political Agency with Emotional

This paper extends the political agency approach to an environment in which voting may be divided between informed and instrumental, informed and ‘expressive’ and uninformed due to ‘rational irrationality’. It constructs a model where politicians may be good, bad or populist. Initially the existence of only good and populist politicians is assumed and the incentives for good politicians to pool with or separate from populists are investigated and the implications for voter welfare are explored. The paper goes on to consider the inclusion of bad politicians. The paper makes three main contributions. First, it provides a rational choice analysis of populism as populism is commonly understood. Second, it locates a potential role for government as a persuasive provider of information regarding the quality of policy. Third, when bad politicians are added to the analysis it is found that a little bit of potential corruption could improve voter welfare.
