Experimental Details

Interventions

Intervention(s)
The experiment will be conducted at the Busara Center for Behavioral Economics in Fall 2019. Busara’s participant pool is broadly representative of Nairobi and Kenya. For a separate study, participants will complete risk, time, and form-of-payment multiple price list preference elicitation tasks. Participants also complete a questionnaire, which includes a series of demographic questions and questions about their usage of mobile money. For this study, participants also complete several ambiguity attitude measurement tasks.

Primary Outcomes

Primary Outcomes (end points)
We measure several behaviors thought to be influenced by uncertainty attitudes: smoking, taking a loan, working as a day laborer, and starting a new business. Each behavior is measured as a binary variable: "Have you done X in the last 12 months?"

Behaviors will be examined individually, and aggregated by principal component analysis.

Experimental Design

Experimental Design
We measure ambiguity attitudes in four ways: 1) A multiple price list, similar to l'Haridon et al. (2018) and Barham et al. (2014); 2) A menu task, similar to Cardenas and Carpenter (2013), 3) A matching probabilities task, similar to Dimmock et al. (2016); and 4) qualitative survey questions, inspired by Dohmen et al. (2011). All subjects complete all 4 tasks. The order of the first 3 tasks will be randomized at the session level. The qualitative survey questions will always be asked last.
Experimental Design Details
Randomization Method
The order of tasks is randomized by computer. The quantitative task chosen to pay out is chosen at random by a zTree.
Randomization Unit
The randomization of the order of tasks is at the session level. The randomization of which task pays out is randomized at the individual level.
