Historians agree […]| Econlib

Many people believe that only government intervention prevents rampant discrimination in the private sector. Economic theory predicts the opposite: market mechanisms impose inescapable penalties on profits whenever for-profit enterprises discriminate against individuals on any basis other than productivity. Though bigoted managers may hold sway for a time, in the long run the profit penalty makes […]| Econlib

Externalities undermine the social benefits […]| Econlib

Compound Rates of Growth In the modern version of an old legend, an investment banker asks to be paid by placing one penny on the first square of a chessboard, two pennies on the second square, four on the third, etc. If the banker had asked that only the white squares be used, the initial […]| Econlib
When economists refer to the “opportunity cost” of a resource, they mean the value of the next-highest-valued alternative use of that resource. If, for example, you spend time and money going to a movie, you cannot spend that time at home reading a book, and you cannot spend the money on something else. If your […]| Econlib
