INTERNATIONAL AND INSTITUTIONAL R&amp;D SPILLOVERS: ATTRIBUTION OF BENEFITS AMONG SOURCES FOR BRAZIL'S NEW CROP VARIETIES
Provedor de dados: 31
Autores: Pardey,   Philip G.; Alston,   Julian M.; Chan-Kang,   Connie; Magalhaes,   Eduardo Castelo; Vosti,   Stephen A.
In general, reported rates of return to agricultural R&amp;D are high, but questions have been raised about upward biases in the evidence.  Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of which is illustrated here with new evidence for Brazil.  Over the period 1981 to 2003, varietal improvements in upland rice, edible beans, and soybeans yielded benefits attributable to research of $14.8 billion in present value (1999 prices) terms; 6.1 percent of the corresponding value of crop output.  If all of those benefits were attributed to Embrapa, a public research corporation accounting for more than half Brazil's agricultural R&amp;D spending, the...
