Does the Commercialization of Voluntary Organizations ‘Crowd out’ Voluntary Work?

This article examines the relationship among voluntary labour supply and commercial income for Norwegian sport voluntary organizations. Empirical results using cross–sectional data on voluntary sport organizations in Norway and on their members show a decrease in voluntary work from an increase in commercial income. Voluntary work and commercial income appear as substitutable resources. Nevertheless, the results have to be differentiated according to the professional situation of the volunteers.
A crowding out effect between voluntary work and commercial resources is at play for non–professionally active individuals whereas professionally active individuals seem to be indifferent to the level of commercial resources in deciding whether to volunteer or not.
