Quem disse que economistas não têm sentido de humor?

"Economic analysis was applied to problems previously considered to lie in the realm of other social sciences, notably sociology and political science. Gary Becker (1930-) has applied standard price theory to, among other sociological topics, crime and the family. Criminal activity is modelled as an optimization problem, in which potential criminals weigh up the gains to be obtained from successful crimes against the potential losses they would incur in the event of being caught and convicted. (...) Similar models can be used to analyse decisions within the family (...) These developments have led to economists becoming the butt of many jokes, such as in an article on the economics of brushing teeth which parodied Becker's method of analysis."
