The goal of this project is to understand whether it is possible and desirable to charge a positive price for business-training programs. We elicit willingness to pay for a course for entrepreneurs in Jamaica. First, we estimate the demand schedule for the program. Second, we study whether willingness to pay can act as a screening device to select those entrepreneurs who would benefit the most from participation in training programs. Third, we test whether there is a sunk-cost effect by which those who pay a higher price for the program exercise more effort (attend the training more regularly) and achieve higher returns. This project is relevant to understand whether we can increase the effect of business-training programs by targeting, and whether providers can achieve financial sustainability by charging a positive price without screening out a large share of entrepreneurs who might participate only if the program is offered for free.

Experimental Details
Our intervention is based on two parts: (i) experiments with entrepreneurs to elicit their willingness to pay for an entrepreneurship program, and (ii) implementation of the training for the entrepreneurs with WTP higher than the randomly drawn price.

Experimental Design
Experimental Design
The design is based on eliciting willingness to pay for the training program using multiple price lists, similar to a discrete version of the Becker-DeGroot-Marschak mechanism (BDM). Participants in our study will be given information about the program in a demonstration class. We will then ask them whether they are willing to pay $X for the entrepreneurship program, where X takes several different values (X=0 in one of the choices). Respondents will be told that one of their choices will be randomly chosen and that the choices are binding. Respondent (as long as they are expected utility maximizers) will have an incentive to reveal the true WTP.
