Local News and the Electoral Incentive to Invest in Infrastructure

Abstract

Despite broad public support, investment in US infrastructure has not kept pace with growth, population shifts, and rising exposure to climate change risks. One explanation lies in politicians’ electoral incentives: because, in the short term, voters see only the costs of investment and not its benefits, politicians have incentive to pander and spend less than what they or their fully informed constituents would prefer. Local newspapers could help reduce this constraint by increasing politicians’ confidence that voters will receive information that justifies higher spending. In a survey experiment, we found that informing US city and county elected officials about news coverage of infrastructure failures increased support for a costly investment for those in competitive electoral settings. When motivated by reelection, politicians need the benefits of investment to be visible in order to justify its costs. Our results demonstrate the political importance of the nonpolitical news covered in local newspapers.
