Household Production and Symptoms of Stress in Post-Soviet Russian Villages1

Abstract This paper examines the impact of human capital (the number of working age household members), social capital (social exchange helping networks and community integration), technological capital (use of mechanical agricultural tools), and village of residence on stratification of Russian peasant households in the post-Soviet era. Findings from a 1995 survey of households in three Russian villages show that the number of working age adults in the household has the strongest influence on household agricultural production. Social capital and technological capital also are associated with differences in the amount of sales obtained from household production. One village, which is located in an oblast (province) which has a program to assist peasant households had substantially higher agricultural production than did the other two villages which are located in oblasti without such programs. The number of working age adults in the household, social exchange networks, and community attachment are negatively associated with symptoms of stress, while higher village levels of production are associated with higher average levels of symptoms of stress in the village. The implications of the findings for the future of Russian agriculture and Russian rural village life are discussed.
