Frank Morgan's Math Chat - Our Favorite Tax

MATHCHAT

March 1, 2001

Old Challenge. What kind of tax is best for the economy?

Answer. In a certain theoretical ideal, the best tax for the economy would be a fixed dollar amount per adult, since there would be no disincentive to initiative or consumption; but such a per capita tax would be impractical as well as unfair. Fairer would be a flat tax (fixed percentage) on consumption. Still fairer would be a flat tax on income.

Riddle (Alex Glasser). Is there something amiss in the opening of O. Henry's famous Christmas story, "The Gift of the Magi":

"One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies...Three times Della counted it. One dollar and eighty-seven cents. And the next day would be Christmas."

New Challenge (Al Zimmermann). In Russian Roulette, five of the six chambers of a water gun are empty, and the sixth is loaded with whipped cream. Two players take turns spinning the chambers of a gun and firing at themselves, hoping to stay clean. The second player has a decided advantage. How can the game be modified so that each player has an equal chance of winning?
