Do Nonpartisan Programmatic Policies Have Partisan Electoral Effects? Evidence from Two Large Scale Randomized Experiments



A vast literature demonstrates that voters around the world who benefit from their governments' discretionary spending cast more ballots for the incumbent party than those who do not benefit. But contrary to most theories of political accountability, some evidence suggests that voters also reward incumbent parties for implementing ``programmatic'' spending legislation, over which incumbents have no discretion, and even when passed with support from all major parties. Why voters would attribute responsibility when none exists is unclear, as is why minority party legislators would approve of legislation that will cost them votes. We study the electoral effects of two prominent programmatic policies that fit the ideal type unusually well. For the first, we implement one of the largest randomized social experiments ever, and find that its programmatic policies do not increase voter support for incumbents. For the second, we reanalyze the study cited as claiming the strongest support for the electoral effects of programmatic policies, which is also a very large randomized experiment. We show that its key results vanish after correcting either a simple coding error affecting only two observations or highly unconventional data analysis procedures (or both). Our results may differ from those of prior research because we were able to marshal large scale experiments rather than observational studies or because we analyze relatively pure forms of programmatic policies rather than mixtures of programmatic and clientelistic policies. However, we conjecture that the primary explanation is the differing nature of the politics for which these policies are passed and implemented. (Last Revised May, 2017)
