Nonâ€pecuniary rewards to work, or psychic income, are a pervasive phenomenon in several labour markets, yet they have been little investigated either theoretically or empirically. Creative industries are a particular case where nonâ€monetary incentives are widely observed. These are also industries where moonlighting commonly occurs because artistic or creative activity is generally low paid, such that workers have to balance their chosen pursuit with another job to make ends meet. In this paper we propose a labour supply model that accounts for the psychic income derived from creative work, monetary remuneration and heterogeneity between occupations in a multiple jobâ€holding context. The model is estimated using threeâ€stage least squares, allowing us to control for simultaneity bias due to the constraint of time and the tendency for multiple jobâ€holdings. We estimate the model using data from a survey of Australian book authors. The use of a proxy for psychic income, measured as the disparity between an authorâ€™s monetary compensation and a shadow price of labour, enables us to gauge the effects of nonâ€pecuniary benefits on the labour supply decisions of this type of creative worker.
