Identification of treatment effects using control functions in models with continuous, endogenous treatment and heterogeneous effects

Florensy, J. P.; Heckman, James J.; Meghirxand, C.; … - 2008

We use the control function approach to identify the average treatment effect and the effect of treatment on the treated in models with a continuous endogenous regressor whose impact is heterogeneous. We assume a stochastic polynomial restriction on the form of the heterogeneity but, unlike...

Simulation and estimation of hedonic models

Heckman, James J. - 2003

semiparametric estimation and identification of scalar additive hedonic models (Ekeland, Heckman, and Nesheim, 2002) and scalar … provide evidence on the performance of several estimation techniques. We also simulate examples of equilibria in nonadditive … models and provide evidence on the performance of the nonadditive estimation techniques developed in Heckman, Matzkin, and …

Using matching, instrumental variables and control functions to estimate economic choice models

Heckman, James J.; Navarro, Salvador - 2003 - Final draft January, 2003

This paper investigates four topics. (1) It examines the different roles played by the propensity score (probabilitiy of selection) in matching, instrumental variable and control functions methods. (2) It contrasts the roles of exclusion restrictions in matching and selection models. (3) It...

Dealing with imperfect randomization : inference for the Highscope Perry Preschool Program

Heckman, James J.; Pinto, Rodrigo; Shaikh, Azeem M. - 2023

This paper considers the problem of making inferences about the effects of a program on multiple outcomes when the assignment of treatment status is imperfectly randomized. By imperfect randomization we mean that treatment status is reassigned after an initial randomization on the basis of...
