Effect of Income Timing and Structure on Savings and Consumption Behavior
The response of consumption to the temporal structure of income streams is fundamental to life-cycle decision making, with important implications for questions about savings, investment, and retirement. It is commonly assumed that less frequent, lumpier income streams can spur savings by helping people overcome the urge to purchase “temptation goods” like alcohol and cigarettes, and by combating pressures from social networks. This assumption is one factor driving the research on commitment savings accounts. On the other hand, converting smooth income streams into larger, deferred sums may also lead to increased temptation and potentially poor choices: “money burning a hole in your pocket”. This project will use an RCT conducted in
rural Malawi to determine which of these effects dominates. We will recruit a random sample of 450 Malawian adults and randomly assign them into three treatment arms – one receiving a smooth stream of income and the other two receiving large lump sums instead. The first lump sum group will receive their lump sums on dates they specify as useful for having a large sum of cash, while the second will receive lump sums on dates that are notably tempting, such as the night before a major local market day.
