The discount rate measures how fast the value of goods diminishes with time. Another ethical consideration is using the theories of prioritarianism and utilitarianism when discussing discount rates for the future in relationship with wealth. If the world’s economy continues to flourish like it is right now, people in the future will have more goods than the present people will. Prioritarianism attaches less value on people’s benefits in the future because future people will be better off.
