Innovation and incentives: evidence from biotech
Financial incentives from state governments are part of a growing trend of policies designed to spur innovation clusters in specific regions. Biotechnology industry clusters in particular have benefited from these subsidies, which have boosted the number of star biotech scientists in those states by roughly 15%. Likewise, the number of biotech jobs overall has grown in states that offered incentives, although they have had little impact on salaries. Incentives have also spilled over to generate sizable effects in local service sectors.

Taxing Billionaires: Estate Taxes and the Geographical Location of the Ultra-Wealthy
We study the effect of state-level estate taxes on the geographical location of the Forbes 400 richest Americans and its implications for tax policy. We use a change in federal tax law to identify the tax sensitivity of the ultra-wealthy?s locational choices. Before 2001, some states had an estate tax and others didn?t, but the tax liability for the ultra-wealthy was independent of their domicile state due to a federal credit. In 2001, the credit was phased out and the estate tax liability for the ultra-wealthy suddenly became highly dependent on domicile state. We find the number of Forbes ...

The effect of state taxes on the geographical location of top earners: evidence from star scientists
Using data on the universe of U.S. patents filed between 1976 and 2010, we quantify how sensitive is migration by star scientists to changes in personal and business tax differentials across states. We uncover large, stable, and precisely estimated effects of personal and corporate taxes on star scientists? migration patterns. The long run elasticity of mobility relative to taxes is 1.6 for personal income taxes, 2.3 for state corporate income tax and -2.6 for the investment tax credit. The effect on mobility is small in the short run, and tends to grow over time. We find no evidence of ...

State Incentives for Innovation, Star Scientists and Jobs: Evidence from Biotech
We evaluate the effects of state-provided financial incentives for biotech companies, which are part of a growing trend of placed-based policies designed to spur innovation clusters. We estimate that the adoption of subsidies for biotech employers by a state raises the number of star biotech scientists in that state by about 15 percent over a three year period. A 10% decline in the user cost of capital induced by an increase in R&D tax incentives raises the number of stars by 22%. Most of the gains are due to the relocation of star scientist to adopting states, with limited effect on the ...
