Abstract This paper develops a unified model of dual and unitary job holding based on a StoneGeary utility function. The model incorporates both constrained and unconstrained labor supply. Panel data methods are adapted to accommodate unobserved heterogeneity and multinomial selection into 6 mutually exclusive labor supply regimes. We estimate the wage and income elasticities arising from selection and unobserved heterogeneity as well as from the Stone-Geary Slutsky equations. The labor supply model is estimated with data from the British Household Panel Survey 1991-2008. Among dual job holders, our study finds that the Stone-Geary income and wage elasticities are much larger for labor supply to the second job compared with the main job. When the effects of selection and unobserved heterogeneity are taken account of, the magnitudes of these elasticities on the second job tend to be significantly reduced.

Dual Job Holding and the Gig Economy: Allocation of Effort across Primary and Gig Jobs

“…There is a long literature on the economic factors driving individuals to select dual job holding on the extensive margin-that is, whether to participate or not (Choe et al 2015;Hirsch et al 2017;Paxson and Sicherman 1996;Renna and Oaxaca 2006). Multiple motivations for holding more than one job have been proposed.…”

“…However, since searches are costly, workers may be reluctant to undertake them until the difference between current job match and expected job match is large. As a number of economists have noted, however, one possible strategy to reducing the costs of searching is to retain the primary job and instead search for a second job—that is, to moonlight (Choe et al ; Renna and Oaxaca ). Various justifications for finding secondary employment have been proposed.…”

Deutschland – Nebenjobberland

“…B. Choe et al 2018 ;Lalé 2016 ;Hirsch et al 2016 ;Panos et al 2014) Um diese Hypothesen zu unterscheiden, müssen in einem einheitlichen methodischen Rahmen die Effekte des Lohns und der Arbeitszeit gemeinsam bestimmt werden. Dadurch werden Einkommensbeschränkungen aufgrund zu weniger Arbeitsstunden nicht mit Einkommensbeschränkungen aufgrund zu geringen Stundenlohns vermengt.…”

Is There a Business Cycle Effect on the Incidence of Dual Job Holding?

“…Interestingly, not every dual job holder seeks a second job in response to an underemployment condition on the main job. In fact, there is strong evidence that the largest proportion of workers hold two jobs for reasons other than an hours constraint (Choe et al, 2018). These alternative motives include: 1) a way to gradually transition to a new primary job or to self-employment (Panos et al, 2014); 2) seeking utility enhancing characteristics on a second job that are not available on the main job because jobs are not perfect substitutes (Kimmel and Smith Conway, 2001); or 3) two jobs may be complimentary with one another such as when the worker uses the credential earned on one job to provide consulting services on the side (Paxson and Sicherman, 1996).…”
