Spending per scientist declined precipitously within African agricultural R&D agencies over the past several decades. In 1991, average cost per researcher across 147 R&D agencies was $119,300 in 1985 international dollars–or US$59,500 when measured in United States rather than international dollars—34 percent below the corresponding 1961 figure. This trend reflects the rapid growth in numbers of scientific staff compared with the slow growth in funds to support them. Comparatively low, and often shrinking, real salaries per scientist are a factor too. African scientists were paid an average of US$5,000 in 1991 (or roughly US$7,500 with fringe benefits included), while comparable average salaries for academic staff working in large public... |

In this paper we present measures of land and labor productivity for a group of 98 developed and developing countries using an entirely new data set with annual observations spanning the past three decades. The substantial cross-country and intertemporal variation in productivity in our sample is linked to both natural and economic factors. We extend previous work by dealing with multiple sources of measurement error in conventional agricultural inputs when accounting for observed differences in productivity. In addition to the mix of conventional inputs in agriculture, we find that indicators of quality change in these inputs and the amount of publicly provided infrastructure are significant in explaining cross-sectional differences in productivity... |

Appeals for targeting agricultural R&D in developing countries more explicitly to the needs of poor smallholders in marginal areas are often countered by arguments of efficiency. Others, however, taking a political economy perspective, argue that there is a bias in the selection of agricultural R&D projects towards commercial farmers in the better agricultural areas. In this paper, we try to bring the two perspectives together and illustrate how they interact. We analyze R&D budget allocation assuming two distinct R&D opportunity curves one for poor smallholders and one for large commercial farmers. We find that, in contrast to the actual allocation of research resources, an efficient allocation (i.e., equalizing the marginal rate of... |
