The Cobra Effect

Season 4, Episode 4

If you want to get rid of a nasty invasive pest, it might seem sensible to offer a bounty as a reward. But the problem is: nothing backfires quite like a bounty. In this episode of Freakonomics Radio, we look at bounties on snakes in Delhi, India; rats in Hanoi, Vietnam; and feral pigs in Fort Benning, Georgia. In each case, bounty seekers came up with creative ways to maximize their payoff – and pest populations grew. Stephen Dubner and Steve Levitt talk about how incentives don’t always work out the way we expect them to. Later in the hour, if you want to write a book about Winston Churchill, you are going to have to pay. The Churchill estate is intensely protective of Sir Winston’s copyright, so much so that if you write a book about him, you are likely to go into the red. Stephen Dubner talks about who owns words, and what it will cost you to write a book about Churchill.
