      abstract = {By now new modern rice varieties (MVs) with multiple pest  and disease resistance have completely replaced early
MVs,  such as IRS and IR8, except in a few areas of Asia. This  study attempts to identify the changing impacts  of
'first-generation' and 'second-generation' MVs on  productivity in rice farming by estimating the yield  function, while
correcting selectivity bias arising from  the choice of varieties. For this purpose, we used  farm-level survey data
collected for eleven cropping  seasons in Central Luzon in the Philippines from 1966 to  1990. We found that while
the yield advantage of  first-generation MVs over traditional varieties was  limited, the yield-increasing effect of
second-generation  MVs over first-generation MVs was highly significant. In  particular, the adoption of improved
MVs significantly  contributed to yield growth under the irrigated condition  and during the dry season. Thus, we
conclude that the Green  Revolution would not have been revolutionary without the  development and the diffusion
of second-generation MVs with  multiple pest and disease resistance.},
