This document summarizes the costs and benefits of investment in agricultural research and development (R&D) in Haiti. It describes the current problems with food security and low agricultural productivity in Haiti. The solution proposed is establishing an agricultural research institution to transfer new technologies to farmers, with annual spending of $15.13-$36.50 million. Models estimate this investment could increase crop yields by over 100% and lead to a 55-66% rise in rice production by 2040. Discounted benefits are projected to be $719-$871 million by 2050, exceeding costs, indicating agricultural R&D is socially beneficial for Haiti.
