    Year: 2019 | IIM Bangalore
    Source: Statistical Modelling
    DOI: 10.1177/1471082X17747806

Two-stage regression methods are typically used for handling endogeneity in the simultaneous equations models in economics and other social sciences. However, the problem is challenging in the presence of incomplete response and/or incomplete endogenous covariate(s). We propose a Bayesian approach f...(Read Full Abstract)
