Next week, dutiful voters will head to the polls for elections. Among the jobs up for grabs are the Kentucky and Mississippi governorships, the mayorship of San Francisco, and a smattering of municipal and state positions across the country. In many of these races, incumbents are fighting to keep their seats.
In our latest Freakonomics Radio on Marketplace podcast (you can download/subscribe at iTunes, get the RSS feed, listen live via the media player above, or read the transcript), we examine the side effects that elections sometimes produce. Steve Levitt wrote about one such effect several years ago (here is the original study, and here's an update): in mayoral and gubernatorial election years, police forces tend to grow and crime tends to fall.
As Stephen Dubner explains to Kai Ryssdal, incumbents' incentives change when they run for re-election. They might try to perform better, hiring more police or lowering taxes. But they also might cater more to special interests, giving out election-time favors and even enabling illegal activities.
We went out in search of various election-year anomalies and found some pretty interesting stuff.
