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...

Distribution regression difference-in-differences
Fernández-Val, Iván; Meier, Jonas; Vuuren, Aico van; … - 2024
We provide a simple distribution regression estimator for treatment effects in the difference-in-differences (DiD) design. Our procedure is particularly useful when the treatment effect differs across the distribution of the outcome variable. Our proposed estimator easily incorporates covariates...

Rationalizing rational expectations? : tests and deviations
D'Haultfœuille, Xavier; Gaillac, Christophe; Maurel, Arnaud - 2018
In this paper, we build a new test of rational expectations based on the marginal distributions of realizations and … subjective beliefs. This test is widely applicable, including in the common situation where realizations and beliefs are observed …-to-implement way to conduct a sensitivity analysis on the assumed form of expectations. Finally, we apply our framework to test for and …

From micro data to causality : forty years of empirical labor economics
Klaauw, Bas van der - 2014
This overview describes the development of methods for empirical research in the field of labor economics during the past four decades. This period is characterized by the use of micro data to answer policy relevant research question. Prominent in the literature is the search for exogenous...

Incorporating cost in power analysis for three-level cluster randomized designs
Konstantopoulos, Spyros (contributor) - 2008
In experimental designs with nested structures entire groups (such as schools) are often assigned to treatment conditions. Key aspects of the design in these cluster randomized experiments include knowledge of the intraclass correlation structure and the sample sizes necessary to achieve...

Testing for poverty dominance : an application to Canada
Chen, Wen-hao (contributor); Duclos, Jean-Yves (contributor) - 2008
The paper proposes and applies statistical tests for poverty dominance that check for whether poverty comparisons can be made robustly over ranges of poverty lines and classes of poverty indices. This helps provide both normative and statistical confidence in establishing poverty rankings across...

Testing the correlated random coefficient model
Heckman, James J.; Schmierer, Daniel; Urzua, Sergio - 2009
The recent literature on instrumental variables (IV) features models in which agents sort into treatment status on the basis of gains from treatment as well as on baseline-pretreatment levels. Components of the gains known to the agents and acted on by them may not be known by the observing...
