A) Absolute Income Hypothesis B) Relative Income Hypothesis
C) Life Cycle Hypothesis D) Permanent Income Hypothesis

The life-cycle hypothesis postulates that individual consumption in any time period depends on

(ii) the rate of return on his capital, and

(iii) the age of the individual.

The resources available to an individual consist of his existing net wealth and the present value of all his current and future labour incomes.
