This paper presents results of a study of four applications of the “Participatory Market Chain Approach” in Bolivia, Colombia, and Peru. In these cases, the PMCA was used to stimulate pro poor innovation in value chains for coffee, dairy products, native potatoes, and yams. Local and national groups affiliated with the Andean Change Alliance used the PMCA to explore and promote the use of participatory methods in agricultural innovation processes, in order to improve the livelihoods of poor farmers. In this paper, we explain the conceptual frameworks and case study methods used to gather and analyze information on the cases, and then summarize case-study findings for each of the four applications of the PMCA. The case-study findings are analyzed in relation to six themes: (1) fidelity of implementation of the PMCA in the four cases; (2) results of the PMCA; (3) factors that have influenced implementation and results; (4) institutionalizing use of the PMCA; (5) validity of the PMCA theory of change; (6) contributions of participation to the results observed. This analysis is followed by general conclusions and suggestions for improving the PMCA and its future application.
