Why are these crops so successful in some countries but not in others?
Farm level profitability ultimately determines whether farmers adopt
and retain a new technology, but this depends on much more than technical
performance. Recent economic studies in developing countries find positive,
but highly variable, economic returns to adopting transgenic crops.
These studies confirm that institutional factors such as national agricultural
research capacity, environmental and food safety regulations, intellectual
