However, we show that the Arellano-Bonhomme (AB) priors are not simultaneously bias reducing by proving mathematically that although the AB priors always reduce the bias for estimating theta_0, they do not always reduce the bias for estimating M. E.g., in the static panel probit model or, generally, for dynamic panel data models, the AB priors only reduce the bias for estimating theta_0 but not for estimating M, whereas in the static panel logit and Poisson models the AB priors simultaneously reduce the bias for estimating theta_0 and M. Furthermore, we construct priors that we prove are simultaneously bias reducing for general non-linear panel data models including panel probit, and show numerically in a simulation study that the AB priors for a panel probit model do not reduce the bias for estimating M \u2014 the bias of the estimator of M based on the AB priors remains comparable to the bias of the maximum likelihood estimator of M even when the panel is long \u2014 whereas the priors that we construct do.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>This is joint work with my supervisors, Gautam Tripathi and Martin Schumann.
