Inventors are significantly less likely to locate in states with higher taxes, with an elasticity to the net-of-tax rate of 0.11 for local inventors and 1.23 for non-local inventors.

"... We find that inventors are significantly less likely to locate in states with higher taxes. The elasticity to the net-of-tax rate of the number of inventors residing in a state is 0.11 for inventors who are from that state and 1.23 for inventors not from that state. Inventors who work for companies are particularly elastic to taxes. Agglomeration effects appear to matter for location as well: inventors are less sensitive to taxation in a potential destination state when there is already more innovation in that state in their particular field of inventive activity. This is also true if an inventor's employer already has a record of innovation activity in that state.We confirm that firms are responsive to corporate taxes when choosing where to locate by estimating a location choice model at the individual R&D lab level. Our main findings can therefore be summarized as follows. Taxation in the form of both personal income taxes and corporate income taxes matters for innovation along the intensive and extensive margins, and both at the micro and macro levels. Taxes affect the amount of innovation, the quality of innovation, and the location of inventive activity. The effects are economically large especially at the macro state-level, where cross-state spillovers and extensive margin location and entry decisions compound the micro, individual-level elasticities. Not all the effects of taxes at the macro-level are accounted for by cross-state business stealing or spillovers. Corporate inventors are most sensitive to taxation; and positive agglomeration effects play an important role, perhaps in offering a type of compensating differential for taxation.......We have studied the effects of personal and corporate income taxes on innovation in the United States during the 20th century using a series of newly constructed datasets. Our data is sufficiently wide-ranging that we can consider both inventors and firms engaged in inventive activity over a long time period, and we can exploit the numerous changes to the U.S. tax code taking place over the 20th century. We document the effect of taxes at the macro (state) and micro (inventors and firm) levels and attempt to identify the estimates empirically. We find that both personal and corporate taxes matter for innovation. The quantity, quality, and the location of innovation are all affected by the tax system and the effects are quantitatively important. In addition to being able to document and identify these important responses to taxation, our estimates can help calibrate the tax elasticities needed in optimal tax formulas for labor or capital income (see Saez (2001) and Saez and Stantcheva (2018)), as well as quantify the efficiency costs of taxation, which are traded off against the revenue gains. Furthermore, our empirical evidence provides a sense of how firms and inventors respond to the net return to innovation, and not only to tax rates, which are merely a component of that economic calculation. In future work, it would be fruitful to compare the U.S. experience to other countries, historically and contemporaneously. That would require a major data collection effort, as we have undertaken for the U.S., but our analysis highlights the benefits of such investments. Currently we know very little about the impact of taxation on innovation over long time horizons, and our analysis is therefore an important first-step in building a better understanding of a relationship that is critical in policy discussions. While our estimates show that the state-level effects of taxes are not purely due to zero-sum business-stealing, it is still an open question as to how the federal tax rate affects national-level innovation in the U.S., when taking into account the international mobility of inventors, firms and intellectual property. An answer to that question is central to a fuller understanding of a tax regime’s real impact...."
