The Ramsey equation
The social time preference rate, s, is given by:-
- s = δ + ηg
where:
- δ is the pure time preference rate (otherwise known as the utility discount rate);
- η is the elasticity of marginal utility with respect to consumption; and,
- g is the expected future growth rate of consumption.
Evidence based upon the structure of personal income tax rates suggests that the value of η for most developed countries is close to 1.4 [1]
