The lifecycle labor supply model has been proposed as an
explanation for various dimensions of labor supply, including
movements over the business cycle, changes with age, and within-
person variation over time. According to the model, all of these
elements are tied together by a combination of intertemporal
substitution effects and wealth effects. This paper offers an
assessment of the model's ability to explain the main components of
labor supply, focusing on microeconometric evidence for men.
