June 2020Does Poverty Change Labor Supply? Evidence from Multiple Income Effects and 115,579 Bags
with Abhijit Banerjee, Dean Karlan, Christopher R. Udry: w27314
The income elasticity of labor supply is a central parameter of many economic models. We test how labor supply and effort in northern Ghana respond to exogenous changes in income and wages using a randomized evaluation of a multi-faceted grant program combined with a bag-making operation. We find that recipients of the grant program increase, rather than reduce, their supply of labor. We argue that simple models with either labor or capital market frictions are not sufficient to explain the results, whereas a model that allows for a positive psychological productivity effect from higher income does fit our findings.
February 2018Unpacking a Multi-Faceted Program to Build Sustainable Income for the Very Poor
with Abhijit Banerjee, Dean Karlan, Robert Darko Osei, Christopher Udry: w24271
A multi-faceted program comprising a grant of productive assets, training, coaching, and savings has been found to build sustainable income for those in extreme poverty. We focus on two important questions: whether a mere grant of productive assets would generate similar impacts (it does not), and whether access to a savings account and a deposit collection service would generate similar impacts (it does not).
August 2014Fair Weather Avoidance: Unpacking Costs and Benefits in Replication of 'Avoiding the Ask'
with Andrew Steinkruger, Mackenzie Wood, Adam Wooster, James Andreoni, James J. Murphy, Justin M. Rao: w20385
If being asked to give to charity stimulates an emotional response, like empathy, that makes giving difficult to resist, a natural self-control mechanism might be to avoid being asked in the first place. We replicate a result from a field experiment that points to the role of empathy in giving. We conduct an experiment in a large superstore in which we solicit donations to charity and randomly allow shoppers the opportunity to avoid solicitation by using the other door. We find the rate of avoidance by store entrants to be 4.5 percent. However, we also find that the avoidance effect disappears in very cold weather, suggesting that avoidance behavior is sensitive to its cost.

December 2011Avoiding The Ask: A Field Experiment on Altruism, Empathy, and Charitable Giving
with James Andreoni, Justin M. Rao: w17648
If people get joy from giving, then why might they avoid fundraisers? We explore this in a randomized natural field experiment during the Salvation Army's annual campaign. The familiar bell-ringers were placed at one or both of two main entrances to a supermarket, making the ask for a charitable donation either easy or difficult to avoid. Additionally, solicitors either simply rang the bell, or asked "please give" to passersby. Verbally asking dramatically increases the number of givers and the amount of giving, as does having solicitors at both main entrances. However, we also found dramatic avoidance of verbal solicitation, between 26.2% and 32.6%, but negligible avoidance of non-verbal solicitation. Asking has a powerful effect on both giving when asked, and on avoidance. We argue that ...
