Multiple job holding: the artist’s labor supply approach

This paper analyzes a labor supply model in which individuals maximize a utility function that depends on leisure time, consumption and time devoted to an activity that is termed “artistic”. This activity may generate income that depends non linearly on hours dedicated to it. The individual can also work in the labor market (an activity that does not increase utility by itself) in exchange for an hourly wage, and obtain income not related to hours. Conditions are obtained that sort individuals in two groups, part time and full time artists, deriving their labor supply functions in both activities. The predictions of the model are tested empirically using a sample of musicians from a Uruguayan performing rights society.
