Abstract
This paper illustrates differences in estimated
returns to public agricultural research investments
for the U.S. and the Northeast when
value-added (VA) as opposed to gross production
(GP) functions are estimated. Commodity groups
considered are dairy, poultry, other livestock,
and cash grains. Sizable differences are evident
in returns estimated with VA as opposed to GP
functions, with the VA estimates generally being
larger. Cash grains research yields the largest
returns at the margin. Dairy research is more
productive in the Northeast than the rest of the
country.
