Incentives

"Most of economics can be summarized in four words: 'people respond to incentives'. The rest is commentary." - Steven Landsburg

Many times the two best words you can hear when you are apartment hunting (especially if you are a broke college student) are "utilities included". I can say from personal experience that it is awesome. People in New York City do too, but having utilities included in the rent may cause some unintended consequences.

Also, I found the quote above here amoung some great quotes about economics and government. Some of those quotes are from my new favorite POTUS.
