Experimental Design
The experiment's sample consists of households engaging in livestock management activities in Narok County, Kenya. Households that refuse to participate will be excluded from the experiment. We target 774 households, who will be randomly assigned to different weeks of the survey.
This study will take place in Narok County, Kenya, from January 2025 to May 2025. Participants will be surveyed by enumerators, including detailed data on recent expenses. The survey will be programmed via Commcare and conducted on a tablet. The BDM exercise will take place after the survey; during it, participants will be able to purchase the ITM vaccine at a (potentially) subsidized rate.
For the exercise, participants will first state the number of calves they want to vaccinate. Participants will then state their maximum WTP for vaccinating the chosen number of calves. A random price will then be drawn from a predefined distribution. If this random price is less than or equal to the participant's WTP, they will purchase the vaccine at the drawn price. If the random price is higher, they cannot buy the product through the survey.
The data collection process will involve randomizing the order in which participants will be surveyed. Specifically, each participant will be randomized to receive the survey and WTP elicitation in a pre-specified week during the survey period (January 2025 to May 2025). This randomization is expected to introduce exogenous variation in liquidity constraints based on seasonality and the randomness of recent events.
Participants who successfully purchase the vaccine through the WTP exercise will have 48 hours to gather/raise funds. They will be notified of the potential vaccination opportunity one week in advance of their randomly assigned survey week. This notification is to enable households to gather funds before the visit, mimicking the typical purchase environment for the vaccine.
