Heckman and Vytlacil (2005) introduced the marginal treatment effect (MTE) to provide a choice-theoretic interpretation for the widely used instrumental variables model of Imbens and Angrist (1994).The MTE can be used to formally extrapolate from the compliers to estimate treatment effects for other subpopulations.
