演講摘要 : This paper investigates identification and estimation of models with nonseparable, multidimensional disturbances using control variables. Triangular simultaneous equations models are considered, with instruments and disturbances independent and reduced form that is strictly monotonic in a scalar disturbance. It is shown that in that setting the conditional cumulative distribution function of the endogenous variable given the instruments is a control variable. Also, for any control variable, identification results are given for quantile, policy, and derivative effects. Bounds for average and quantile effects are given when a common support assumption is not satisfied. Estimators of identified objects and bounds are provided and a demand analysis empirical example given.
