Abstract
The opportunity to free-ride on other individuals' learning costs can delay technology adoption or lead to sub-optimal adoption rates.
I study learning about a pest-control technology among small-holding farmers in Uganda. In this context, delayed adoption may enable a large scale infestation with sizeable economic effects.
I identify two types of free-riding in my setting, namely free-riding on information and free-riding on action.I attempt at separating the two by exploiting experimental variation induced by information interventions.

Experimental Design
Experimental Design
I elicit farmers' willingness-to-pay (WTP) for a training session of 3 hours with an agricultural extension worker, focused on the maize pest Fall Armyworm. The recipient of the training may be the farmer herself or another sampled farmer in her village. Therefore, I elicit as many prices from each farmer as the number of sampled farmers in her village including herself. Prices are elicited through a Becker-DeGroot-Marschak mechanism and range from 0 to 40,000 Ugandan Shilings (UGX) in increments of 2,000. Each farmer is assigned a single random price for the training, and a farmer can purchase the training only if her stated WTP is at least as large as the random price.
Experimental Design Details
The design is within-subject, such that each subject is exposed to two information treatments and one control condition. In the control condition, a farmer is simply asked about her WTP for training if the recipient is another farmer in the village. In the first treatment condition, before a farmer is asked about her WTP for another farmer in the village (not the same farmer as in the control condition), she is informed that she will have the opportunity to meet that person. In the second treatment condition, before a farmer is asked about her WTP for another farmer (not the same farmer as in the control or first treatment condition), she receives information on the distance between her plot and that of the other farmer.
Randomization Method
The randomization is performed through a personal computer running Stata software.
Training prices are preassigned and stratified by the treatment assignment of a previous RCT that the author is conducting on the same sample.
The name of the farmer(s) that the respondent is going to either meet or be informed about plot distance are also selected at random and all equally likely.
Randomization Unit
The randomization unit for both training price assignment and information treatment is the individual.
Was the treatment clustered?
No
Experiment Characteristics
Sample size: planned number of clusters
799 farmers express their willingness-to-pay to train each other sampled farmer in the village. This yields a total of 5498 prices elicited, which is my unit of observation.
