We partnered with a savings product provider in Kenya to test the extent to which behavioral interventions and financial incentives can increase the saving rate through a voluntary pension program for informal workers with low and irregular income. Our experiment lasted for six months and included a total of twelve conditions. The control condition received weekly reminders and balance reporting via text messages. The treatment conditions received in addition one of the following interventions: (1) reminder text messages framed as if they came from the participant’s kid (2) a golden colored coin with numbers for each week of the trial, on which participants were asked to keep track of their weekly deposits (3) a match of weekly savings: The match was either 10% or 20% up to a certain amount per week. The match was either deposited at the end of each week or the highest possible match was deposited at the start of each week and was adjusted at the end. Among these interventions, by far the most effective was the coin: Those in the coin condition savedon average the highest amount and more than twice as those in the control condition. We hypothesize that being a tangible track-keeping object; the coin made subjects remember to save more often. Our results support the line of literature suggesting that saving decisions involve psychological aspects and that policy makers and product designers should take these influences into account.  \nJEL Classification: G21, B49, D03  \nKeywords: savings, field experiment, behavioral economics  \nCorresponding author:  \nMerve Akbas Aliya Analytics  \n20 Marshall St. , Suite 102 South Norwalk CT 06854 USA [E-mail:](E-mail: merve@aliya.com)[ merve@aliya.com](E-mail: merve@aliya.com)  \n1 We thank the Trust Fund for En","cbCainIp9eK8Da9u","https://ap.wps.com/l/cbCainIp9eK8Da9u","pdf",353999,34,"English","# Abstract\n## Interventions and experiment design\n## Findings and policy implications","[{\"question\":\"What was the main objective of the Kenya field experiment?\",\"answer\":\"To test how behavioral interventions and financial incentives affect the saving rate of low- and irregular-income informal workers through a voluntary pension program.\"},{\"question\":\"Which treatments were compared against the control condition?\",\"answer\":\"The control received weekly reminders and balance reporting via text messages; treatment added one of: kid-framed reminder texts, a tracking coin, or matched weekly savings with specified rates and deposit timing.\"},{\"question\":\"What intervention was most effective in increasing savings?\",\"answer\":\"The coin condition produced the highest average savings and more than doubled savings relative to the control, supporting the idea that tangible tracking objects improve saving frequency.\"}]","IZA Discussion Paper No. 10024 - How to Help Poor Informal Workers to Save a Bit - Evidence from a Field Experiment in Kenya | PDF",86]
