Eduardo Porter uncovers the true story behind the prices we pay and reveals what those prices are actually telling us. He takes us on a global economic adventure, from comparing the relative price of a vote in corrupt São Tomé and in the ostensibly uncorrupt United States, to assessing the cost of happiness in Bhutan, to deducing the dollar value we assign to human life. His unique approach helps explain: * Why polygamous societies actually place a higher value on women than monogamous ones. * Why someone may find more value in a $14 million license plate than the standard issue, $95 one. * Why some government agencies believe one year of life for a senior citizen is four times more valuable than that of a younger person.
