Anticipate Moral Hazard
Thirty-seven years ago, Charles de Gaulle decided to spring a treat on the voters of France after they reelected him. He declared an amnesty on outstanding traffic offenses. It was a wildly popular scheme--and every French president since then has repeated the gesture.
These amnesties still serve to enhance the honeymoon effect for newly chosen chief executives. The only problem is that French drivers, knowing that they will be forgiven, drive like maniacs in the months leading up to the election. This isn't just a matter of anecdote: Highway deaths in France consistently increase by significant percentages just prior to an election. In May 2002, the month before France reelected President Jacques Chirac, there were 616 fatalities, compared with 553 during the same period the year before.
