University of Rochester Professor Stephen Landsburg offers a look through the eyes of an economist at the problems that each of us faces in everyday life. Some of them may make you smile (for example, questions about why popcorn in cinemas costs so much, why celebrity concerts attract sold-out houses, or why laws prohibiting polygamy are disadvantageous to women), others are completely serious and concern unemployment, inflation and interest rates. But they are united by the fact that only economics can give a clear answer to them. This book shows how widely economics can be applied and how well it allows us to solve the puzzles that arise in everyday life.
