Abstract: This paper reexamines the empirical validity of the intertemporal substitution hypothesis by reinterpreting existing empricial labor supply studies. A dynamic labor supply model is proposed and is used as a unifying framework for various studies. Evidence discernible from those reinterpretations supports the view that a typical worker increases working hours in response to a wage increase perceived to be transitory, but decreases working hours in response to a permanent wage increase. Specifically, the evidence strongly suggests that the short run labor supply elasticity exceeds 1.
