  • Overidentification tests for the exogeneity of instruments in discrete choice models 

    Guevara Cue, Cristian (Elsevier, 2018)
    Endogeneity is often present in discrete choice models, precluding the consistent estimation of the model parameters. To correct for this problem, the researcher needs to gather exogenous instrumental variables, which ...
