  abstractNote={In a sample of Tanzanian formal sector workers the vast majority have a desire for working longer hours in their main job, and supplement earnings through participation in informal production. Determinants of participation in informal production are examined through estimation of structural-form Logit models. A new way around the problem of measuring incomes from informal production is suggested and evaluated. The results show that participation in informal production is inversely related to income, and positively related to age. Age seems to play a very different role in the transition from work to retirement in Tanzania compared to industrialised countries. JEL classification: D13; J22},
