Simulation and Estimation of Nonaddative Hedonic Models

Heckman, James J.; Matzkin, Rosa L.; Nesheim, Lars - 2021

Making use of restrictions imposed by equilibrium, theoretical progress has been made on the nonparametric and semiparametric estimation and identification of scalar additive hedonic models (Ekeland, Heckman, and Nesheim, 2002) and scalar nonadditive hedonic models (Heckman, Matzkin, and...

A Note on Adapting Propensity Score Matching and Selection Models to Choice Based Samples

Heckman, James J. - 2010

The probability of selection into treatment plays an important role in matching and selection models. However, this … note establishes that the selection and matching procedures can be implemented using propensity scores fit on choice …

The Identification and Economic Content of Ordered Choice Models with Stochastic Thresholds

Cunha, Flavio - 2007

This paper extends the widely used ordered choice model by introducing stochastic thresholds and interval-specific outcomes. The model can be interpreted as a generalization of the GAFT (MPH) framework for discrete duration data that jointly models durations and outcomes associated with...

Instrumental Variables, Selection Models, and Tight Bounds on the Average Treatment Effect

Heckman, James J.; Vytlacil, Edward - 2021

This paper exposits and relates two distinct approaches to bounding the average treatment effect. One approach, based on instrumental variables, is due to Manski (1990, 1994), who derives tight bounds on the average treatment effect under a mean independence form of the instrumental variables...

Causal Parameters and Policy Analysis in Economcs : a Twentieth Century Retrospective

Heckman, James J. - 2021

The major contributions of twentieth century econometrics to knowledge were the definition of causal parameters when agents are constrained by resources and markets and causes are interrelated, the analysis of what is required to recover causal parameters from data (the identification problem),...

Making the Most Out of Social Experiments : Reducing the Intrinsic Uncertainty in Evidence from Randomized Trials with an Application to the Jtpa Exp

Heckman, James J.; Smith, Jeffrey A. - 2022

This paper demonstrates that even under ideal conditions, social experiments in general only uniquely determine the mean impacts of programs but not the median or the distribution of program impacts. The conventional common parameter evaluation model widely used in econometrics is one case where...

Labor Supply Estimates for Public Policy Evaluation

Borjas, George J.; Heckman, James J. - 2021

In recent years, the study of labor supply has occupied the attention of a large number of economists. With the growth in interest in the topic and with the inevitable diversity of economic models and statistical methods proposed by new entrants in the field, the literature has developed its own...

Nonparametric Identification and Estimation of Nonadditive Hedonic Models

Heckman, James J. - 2010

This paper studies the identification and estimation of preferences and technologies in equilibrium hedonic models. In it, we identify nonparametric structural relationships with nonadditive heterogeneity. We determine what features of hedonic models can be identified from equilibrium...

Dynamic Discrete Choice and Dynamic Treatment Effects

Heckman, James J.; Navarro-Lozano, Salvador - 2021

This paper considers semiparametric identification of structural dynamic discrete choice models and models for dynamic treatment effects. Time to treatment and counterfactual outcomes associated with treatment times are jointly analyzed. We examine the implicit assumptions of the dynamic...
