The classical Heckman (1976, 1979) selection correction estimator (heckit) is misspecified and inconsistent if an interaction of the outcome variable and an explanatory variable matters for selection. To address this specification problem, a full information maximum likelihood estimator and a...

An important paper by Chiappori et al. (2012) has proposed an elegant and parsimonious model of spousal matching over multi-dimensional characteristics. Importantly, the model suggests specific testable assumptions that allow researchers to uncover marginal rates of substitution (MRS) between...
