内容简介
Steven Landsburg's writings are living proof that economics need not be "the dismal science." Readers of The Armchair Economist and his columns in Slate magazine know that he can make economics not only fun but fascinating, as he searches for the reasons behind the odd facts we face in our daily lives. In More Sex Is Safer Sex, he brings his witty and razor-sharp analysis to the many ways that our individually rational decisions can combine into some truly weird collective results -- and he proposes hilarious and serious ways to fix just about everything.
When you stand up at the ballpark in order to see better, you make a rational decision. When everyone else does it too, the results, of course, are lousy. But this is just the tip of the iceberg of individual sanity and collective madness. Did you know that some people may actually increase the spread of sexually transmitted diseases when they avoid casual sex? Do you know why tall people earn more money than shorter competitors? (Hint: it isn't just unfair, unconscious prejudice.) Do you know why it makes no sense for you to give charitable donations to more than one organization?
