EXECUTIVE SUMMARY
In this study, we assess the potential economic impact of the first, Guinea-race sorghum hybrids produced and diffused using the new research and development paradigm (PPB-F), comparing it to what would have been achieved through the earlier approach (PPB-S). To incorporate risk into our analysis, we augment the economic surplus model by applying Monte Carlo sampling to simulate distributions of model parameters. Thus, rather than provide a single estimate of the total economic surplus, net present value, and internal rate of return, the analysis generates a range of estimated values, their minima, maxima, means and modes. We then explore which factors most influence variation in economic returns; these lend insights for policy.
