Stiglitz: It's time to retire metrics like GDP. They don't measure everything that matters.

I propose three numbers to measure the overall health of the economy:

• What fraction of the cost of basic needs can some with a 20th percentile income have?
• What fraction of the cost of basic needs can someone with no income have for basic needs?
• What is the most a person with a 20th percentile income or less ever has to pay in order to access medical treatment?
