Replication Data for: Vote Buying and Negative Agenda Control: A Problem for the Study of Money in Politics

Politicians, pundits, and ordinary citizens frequently argue that money has an outsized influence on US politics. Yet research on the effect of money on politicians' behavior finds limited effects, especially on voting behavior. I construct a formal model to show that these limited effects may be an artifact of the institutional powers of agenda setters, and the strategic nature of the data generating process. The model predicts that, under general conditions, vote buying against proposals can occur with no vote held, and that vote buying is most likely when uncertainty is high, the interest group and agenda setter are extreme, and the pivotal legislator is moderate. I argue that these conditions held during the 2021 negotiations over the Build Back Better Act. Using a synthetic control design, I test whether the swing voters in the Senate received more campaign contributions than they would have otherwise, finding evidence consistent with the model.
