Comparing IV with structural models : what simple IV can and cannot identify

Heckman, James J.; Urzua, Sergio - 2010

This paper compares the economic questions addressed by instrumental variables estimators with those addressed by structural approaches. We discuss Marschak's Maxim: estimators should be selected on the basis of their ability to answer well-posed economic problems with minimal assumptions. A key...

Analyzing social experiments as implemented: evidence from the HighScope Perry Preschool Program

Heckman, James J.; Moon, Seong Hyeok; Pinto, Rodrigo; … - 2010

Social experiments are powerful sources of information about the effectiveness of interventions. In practice, initial … paper develops tools for analyzing data from experiments as they are actually implemented. We apply these tools to analyze … the influential HighScope Perry Preschool Program. The Perry program was a social experiment that provided preschool …

Randomization and social policy evaluation revisited

Heckman, James J. - 2020 - This draft, December 12, 2019

This paper examines the case for randomized controlled trials in economics. I revisit my previous paper "Randomization and Social Policy Evaluation" and update its message. I present a brief summary of the history of randomization in economics. I identify two waves of enthusiasm for the method...

Simulation and estimation of hedonic models

Heckman, James J.; Matzkin, Rosa L.; Nesheim, Lars - 2003

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...

Identification and estimation of hedonic models

Ekeland, Ivar; Heckman, James J.; Nesheim, Lars - 2003

This paper considers the identification and estimation of hedonic models. We establish that in an additive version of the hedonic model, technology and preferences are generically identified up to affine transformations from data on demand and supply in a single hedonic market. For a very...

Evaluating marginal policy changes and the average effect of treatment for individuals at the margin

Carneiro, Pedro; Heckman, James J.; Vytlacil, Edward - 2009

This paper develops methods for evaluating marginal policy changes. We characterize how the effects of marginal policy changes depend on the direction of the policy change, and show that marginal policy effects are fundamentally easier to identify and to estimate than conventional treatment...

Bayesian exploratory factor analysis

Conti, Gabriella; Frühwirth-Schnatter, Sylvia; … - 2014

This paper develops and applies a Bayesian approach to Exploratory Factor Analysis that improves on ad hoc classical approaches. Our framework relies on dedicated factor models and simultaneously determines the number of factors, the allocation of each measurement to a unique factor, and the...
