Resumen de Why bother campaigning?: Campaign effectiveness in the 2009 European Parliament elections

Maria Laura Sudulich, Matthew Wall, David M. Farrell

• This paper explores the effectiveness of European Parliament candidates' campaigns. We analyze the relationship between candidates' spending and their likelihood of success, controlling for a range of relevant co-varying factors. We then investigate whether the effects of electoral spending are conditioned by two variables: ballot design and incumbency. We find that, ceteris paribus, spending was positively related to a candidate's likelihood of electoral success in the 2009 campaign, though this effect is small in scale. We also reveal that the electorally positive effects of spending are observable across both 'party-centered' and ‘candidate-centered’ ballot structures, and that there is some evidence that incumbent spending is less effective than challenger spending.
