Conteúdo: | Studies of returns to agricultural research have yielded results suggesting that the investment has been enormously socially profitable. Many of the estimates are likely to have been biased upwards, hoiwever, as a result of attribution problems. The challenge is to determine what productivity growth would have been in the absence of a particular research investment. The typical approaches understate the period over which research affects productivity and, in econometric studies using time-series data, this means they over-state the shorter-term impacts, leading to overstated rates of return. Typical approaches also fail to take into account the effects of work done by others in the research-debelopment-extension continuum, and this gives too much credit to the particular investor being evaluated. Corresponding work remains to be done to establish the empirical imporatance of incomplete correction for loc ational spillovers of resdearch results in biasing estimated of return to research.
