The Effects of SSI and DI on the Employment of the Disabled

The causal relationship between SSI benefits and employment status is examined, to determine if SSI reduces disabled employment. An econometric approach not previously used to study this question employs bivariate probit models and captures the marginal effects on work status and SSI enrollment. Additionally, state-level explanatory variables are used to capture the inherent differences between states and policy simulations predict changes in the SSI rolls. **The author would like to thank Dr. Marjorie Baldwin and Dr. G.
