Q.1 In evaluating the entire Roundup Ready soybean system, taking into account any differences in convenience, labor, peace of mind, etc., do you believe the Roundup Ready soybean system has a _____ than non-Roundup Ready soybeans?
Q.2 If you had to assign a dollar figure to the [added/lower] value of the Roundup Ready soybean system, [above/below] the value of non-Roundup Ready soybeans, how much would you say the [added/lower] value would be on a per-acre basis? In other words, how much [more/less], per acre, would you say the Roundup Ready soybean system is worth to you compared to other programs?

What did we learn?
Measurement of economic benefits from adoption of biotech soybeans and other crops complicated by sparse data on farm level impacts
Many impacts remain difficult to measure and may explain divergence of adoption and measured impacts found in many studies
Global impacts from adoption of biotech crops are very large – close to $60 billion between 1996 and 2009 in the case of soybeans
