The Impact of the Source of Changes in Marginal Tax Rates on Participation in Individual Retirement Accounts
利用两年期面板税收数据，研究税率变化来源（应税收入变动 vs 税表直接调整）对个人退休账户参与决策的影响，发现前者影响更大。
This paper uses a series of two-year panels of tax return data to estimate the effects of two sources of tax rate changes on the participation in Individual Retirement Accounts (IRAs). This paper uses a panel logit approach to control for individual specific fixed effects, which may also influence IRA participation behavior. This paper examines participation during the years of open eligibility for IRAs, as well as examining the impact of the 1986 tax reform on participation. A key finding of this paper is that taxpayers' IRA participation decisions are more sensitive to changes in tax rates due to changes in taxable income than to direct changes in the tax tables.
