| Abstract
| - Returns to research studies have neglected research on crop management (CMR), which may account for half of all crop research. Because CMR enhances the efficiency of input use, returns to CMR are hypothesized to increase in settings characterized by high input levels and high yields. A method is developed to estimate returns to CMR, and this method is applied to wheat research in a post-green revolution setting in northwest Mexico. The results suggest that returns to CMR are positive over a range of model assumptions.
