To raise school participation, many programs in developing countries eliminate or reduce private contributions to education. Using data from a randomized experiment in Ecuador, we ironically find that announcing a free school uniform program had a negative impact on attendance. The school uniforms were distributed in only 63% of the schools that were told that they would get them, thus this negative impact could have been generated by creating false expectations of free distribution, or also by a sunk cost effect on those who did actually receive the uniforms.
