Found elasticity of taxable income by income category to be .728 for income > $50k, 1.023 for >$100k, 1.413 for >$250k, and 2.0 for > $1 million. Also derived the tax revenue responses to reductions in marginal taxes for those earning more than $200k / yr. Revenues increased by 19% in 1982, 35% in 1983, 56% in 1984.
Other work indicates a negative effect of tax rates on economic growth and stimulus.
