Last week Amazon finally announced that New York and Northern Virginia would be the sites of its planned major expansion. While many are caught up in the excitement of Amazon bringing 25,000 high-paid jobs to both metropolitan areas, it is worth thinking through the costs that beauty contests like this one impose on state and local governments. Amazon extracted billions of dollars in concessions from the winners and could have extracted even more from some of the other cities courting them.

It is economically rational for companies to create such Hunger Games-type competitions among communities. These competitions reduce their costs and improve their bottom lines. But is it economically rational for the cities? As long as governments are acting independently, yes, it is rational for them to race to the bottom to secure a win. So long as they are a bit better off by snagging the prize than they would have been otherwise, they come out ahead. But the metrics that politicians use are unlikely to be limited to a hard-nosed accounting of costs and increased tax revenues. Positive buzz may be enough to satisfy them.
