Abstract
In this study, we work with Mars Corporation (owners of the Wrigley Kenya) to offer microfinance contracts to fund the purchase of a bicycle for microentrepreneurs who work under Wrigley's micro-distribution programme in Kenya, "Maua". Our sample consists of micro-distributors, many of whom sell retail products (which include chewing gum) on foot, and who would like to finance the purchase of a bicycle to expand their micro-distribution activities.

Experimental Design

Experimental Design
We use a randomised controlled trial design, in which respondents are assigned either to a control group or to one of five treatment groups, each corresponding to a contract with a different repayment structure. We also elicit preferences over each of the five contracts using a strategy method. This process is described in more detail in the pre-analysis plan document.
