Is the GDP Still Accurate in the Digital Age?

GDP is the sum of all income earned in a country during a year. Alternatively, it can be thought of as the value of all production in an economy during a year. But do income and production measure happiness?The way we measure GDP can both overstate and understate people's happiness and well-being. It understates economic activity and well-being when it does not take into account production that is not exchanged in a market (grandma providing free baby-sitting) and leisure time. It overstates well-being when two otherwise identical activities are measured the same even though one produces more pollution.

Should we continue to measure GDP as we do now? If you don't think it should be changed, explain your reasoning. If you think it should be changed, what changes would you recommend, and why?
