Abstract
The distribution of welfare gains of genetic improvements in major US crops is estimated using a world agricultural trade model. Multi-market welfare estimates were 75% larger than estimates based on the price-exogenous ‘change in revenue’ method frequently used by plant breeders. Annual benefits of these genetic improvements range from US$400-600 million depending on the supply shift specification. Of this, 4440% accrues to the US, 2634% accrues to other developed countries. Developing and transitional economies capture 1622% of the welfare gain. The global benefits of a one-time permanent increase in US yields are US$8.1 billion (discounted at 10%) and US$ 15.4 billion (discounted at 5%). Gains to consumers in developing and transitional economies range from US$6.1 billion (10% discount rate) to US$ 11.6 billion (5% discount rate).
