Technology flows matrix estimation revisited
During the early 1980s I estimated a highly disaggregated matrix of technology flows from U.S. industries that performed research and development (R&D) to industries expected to use the R&D outcomes. The results, extended to analyze how technology flows affected productivity growth in the 1960s and 1970s, are reported in Scherer (1982a, 1982b, and 1984). In this paper I return to the scene of the crime two decades later to see whether the desired matrix of technology flows could have been obtained using publicly available information, or information that could be gleaned as a by-product of ...

A note on global walfare in pharmaceutical patenting
This paper revisits the question of whether global welfare is higher under a uniform world-wide system of pharmaceutical product patents or with international rules allowing low-income nations to free-ride on the discoveries of firms in rich nations. Key variables include the extent to which free-riding reduces the discovery of new drugs, the rent potential of rich as compared to poor nations, the ratio of the marginal utility of income in poor as compared to rich nations, and the competitive environment within which R&D decisions are made. Global welfare is found to be higher with ...
