Objective: The objective of this study was to understand the beliefs of Haitian citizens about collective action and cooperativism to assist in the economic development of Haiti through family farming, using Mancur Olson's Collective Action Theory as an analytical theoretical framework. Theoretical framework: The study is based on the "Collective Action Theory", as developed by economist Mancur Olson in his work "The Logic of Collective Action". The theory proposes a model for the construction of collective actions based on the understanding of group needs and the ability to achieve challenging goals. Method: The study is characterized by a qualitative case study, conducted in the interior of "Cayes Jacmel," Haiti, using intentional sampling for interviews with forty Haitian farmers. Results and conclusion: The study observed that family farming depends on the implementation of new technologies and a credit system to boost agricultural practices. The study concluded that cooperativism and collective action in the Haitian context have the potential to boost the development of family farming and promote economic, political, and social progress. Research implications: The study provides critical insights into Haitians' perceptions of collective action and its role in economic development. It underscores the importance of cooperation, challenges political structures, and highlights the need for international aid aligned with sustainable agriculture. Originality/value: The study's originality lies in its focus on collective action as a driver of economic progress, aligning with the scope of the RGSA. The study's value extends to its potential to shape socio-environmental practices within Haitian society.
