Abstract: A common approach to estimating the elasticity of income to taxation is to construct an instrumental variable using synthetic tax rates. Individual-level income dynamics threaten the validity of this instrument, but this problem can potentially be mitigated by group-averaging the instrument. In this article I show that rather than imposing an arbitrary minimum threshold for group sizes to avoid small-sample bias, researchers should use leave-one-out group averages. Using CPS data I show that this correction increases the estimate for broad income elasticity.
