N2  - We summarize the findings of a recently completed study of the productivity impacts
of international crop genetic improvement research in developing countries. Over the
period 1960 to 2000, international agricultural research centers, in collaboration with
national research programs, contributed to the development of “modern varieties” for
many crops. These varieties have contributed to large increases in crop production.
Productivity gains, however, have been uneven across crops and regions. Consumers
generally benefited from declines in food prices. Farmers benefited only where cost
reductions exceeded price reductions
