Two economists have excited the ire of the intellectual community with their findings on the Economics of Prostitution.
They found that wives are normal goods while whores are inferior goods. That is, men consume more wives as their incomes rise, whereas their proportional use of prostitutes falls, which may explain why prostitution is less common in wealthier countries.
On the other hand, the implication remains that wives and whores are substitutable goods in some degree.
