Abstract
This paper estimates a dynamic ordered probit model of self-assessed health
with two fi xed effects: one in the linear index equation and one in the cut points.
This robustly controls for heterogeneity in unobserved health status and in reporting behavior, although we cannot separate both sources of heterogeneity. We fi nd
important state dependence effects, and small, but signi cant effects of income and
other socioeconomic variables. Having dynamics and f exibly accounting for unobserved heterogeneity matters for those estimates. We also contribute to the bias
correction literature in nonlinear panel models by comparing and applying two of
the existing proposals to our model
