This article explores gender differences in three varieties of economic activities that supplement regular employment and housework: entrepreneurial moonlighting, self-provisioning, and casual exchanges with the members of other households. Drawing on data gathered through a random survey and interviews conducted with a white, rural, working-class population, gender differences were found in the content of these activities, their location, the time devoted to them, the degree to which they were delineated from other activities, and the opportunities they provided for sociability. These (...) differences are shown to have consequences for the internal gendered dynamics of the household and for the reinforcement of some kinds of male privilege. (shrink)
