Rational Funk 

The name of a fresh northeastern ska/funk band whose name originated in a math class after "rational fuctions" was abbreviated to "rational func", and eventually to "Rational Funk". After years spent in music class and a day of learning about "rational fuctions", the northeastern ska band Rational Funk was born. Known for their funky cover of "American the Beautiful", renamed "American the Beauti-funk", and also their other patriotic funk-covers.

Dude, have you listened to Rational Funk play in the band room? They're so funkin' awesome!

Rational Hedonism 

A modern, growing Religion based on enjoying the pleasures of this life, now, instead of holding out for a hoped-for heaven after you're dead and it's too late.

Rational Hedonism is a religion revolving around the individual, and the belief that Your world revolves around You.

Rational Hedonism believes in indulging in the things you enjoy, but with responsibility; ie: sex is great, STDs and unwanted pregnancy is not ... following your desires, dreams is cool, going to prison because of it is not.

Ever since Joe discovered Rational Hedonism, he's stopped worrying about trying to please everyone else and started doing the things he loves to do and is much happier.

rational expectations hypothesis  

*noun*; a method of representing the economy as the sum of many identical individuals and firms, each represented by a system of mathematical equations. The Rational Expectations Hypothesis (REH) takes its name from the premise that economic actors, i.e., everyone, do not make consistent errors about the present or future behavior of markets.

REH was devised mainly as a rebuke to Keynesian economics, and in particular, the strategy of fiscal policy or monetary policy.

According to the REH, fiscal policy does not alter aggregate demand because the "average" person recognizes that her lifetime income is not increasing--so she needs to save rather than spend the stimulus money, in anticipation of higher taxes in the future.

At the same time, monetary policy does not work because it relies on lowering interest rates to make more money available; more money means inflation, but people have to be deceived into thinking prices for their product are going up, so they will expand production. According to REH, people or firms will figure this out, and see increased demand as mere inflation. Instead of increasing output and employment, they'll want to raise prices so they can meet their future bills.

According to REH, both monetary and fiscal policy rely on illusions to work; and since people (on average) will make rational estimates o the future, they will defeat these illusions.

The rational expectations hypothesis states that we can break the realization of a return into an expected return that depends on the current information set and an unexpected component that depends only on new information.

rational ignorance 

Choosing to remain uninformed because the marginal cost of obtaining the information is higher than the marginal benefit of knowing it.

Commonly practiced by hicks that don't wish to change their point of views about ANYTHING.

"All dem blackies wanna do is steal turnips outta mah garden!"

"Those Muslims and Hin-don'ts are the devil!"

"Men are pigs!"
