U.S. Tax Policy and the Location of R&D.
研究了美国税收政策如何影响跨国公司研发支出的全球分布，发现研发地点对1981年研发抵免规则和1977年外国税收抵免限制规则敏感。
Abstract This study tests the hypothesis that research and development (R&D) tax policy impacts the worldwide location of R&D expenditures by multinational companies based in the U.S. Although the overall percentage of R&D performed offshore did not change substantially between 1977 and 1989, large shifts by a few industries indicate that R&D can be quite mobile. Overall, R&D expenditure location appears to be sensitive to the R&D credit rules instituted in 1981, as well as the foreign tax credit limitation rules enacted in 1977, suspended in 1982, and reenacted in 1986.
