Testing for Nonparametric Identification of Causal Effects in the Presence of a Quasi-Instrument

de Luna, Xavier; Johansson, Per - Institute for the Study of Labor (IZA) - 2012

The identification of average causal effects of a treatment in observational studies is typically based either on the unconfoundedness assumption or on the availability of an instrument. When available, instruments may also be used to test for the unconfoundedness assumption (exogeneity of the...

When the Cat Is Near, the Mice Won't Play: The Effect of External Examiners in Italian Schools

Bertoni, Marco; Brunello, Giorgio; Rocco, Lorenzo - Institute for the Study of Labor (IZA) - 2012

We use a natural experiment to show that the presence of an external examiner in standardized school tests reduces the proportion of correct answers in monitored classes by 5.5 to 8.5% – depending on the grade and the test – with respect to classes in schools with no external monitor. We...

Evaluating Dominance Ranking of PSID Incomes by Various Household Attributes

Maasoumi, Esfandiar; Heshmati, Almas - Institute for the Study of Labor (IZA) - 2005

We examine the dynamic evolution of incomes, both disposable and gross, for several groups in the PSID panel data at several points from 1968 to 1997. We employ the extended Kolmogorov-Smirnov tests of First and Second Order Stochastic Dominance (SD) as implemented by Maasoumi and Heshmati...

The Revealed Preference Approach to Collective Consumption Behavior: Testing, Recovery and Welfare Analysis

Vermeulen, Frederic; Cherchye, Laurens; Rock, Bram De - Institute for the Study of Labor (IZA) - 2007

nonparametric testing tools for data consistency with special cases of the collective model, which impose specific structure on the … preferences of the group members (in terms of consumption externalities and public consumption); and we show that these testing … income shares that underlie observed (collectively rational) group behavior. In addition, we present formally similar testing …

Unscheduled School Closings and Student Performance

Marcotte, Dave E.; Hemelt, Steven W. - Institute for the Study of Labor (IZA) - 2007

Do students perform better on statewide assessments in years in which they have more school days to prepare? We explore this question using data on math and reading assessments taken by students in the 3rd, 5th and 8th grades since 1994 in Maryland. Our identification strategy is rooted in the...

Testing the Correlated Random Coefficient Model

Heckman, James J.; Schmierer, Daniel; Urzua, Sergio - Institute for the Study of Labor (IZA) - 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...

The Effects of Incomplete Employee Wage Information: A Cross-Country Analysis

Polachek, Solomon W.; Jun (Jeff) Xiang - Institute for the Study of Labor (IZA) - 2005

In this paper, we define a tractable procedure to measure worker incomplete information in the labor market. The procedure, which makes use of earnings distribution skewness, is based on econometric frontier estimation techniques, and is consistent with search theory. We apply the technique to...

Experimental Games on Networks: Underpinnings of Behavior and Equilibrium Selection

Charness, Gary; Feri, Francesco; Meléndez-Jiménez, … - Institute for the Study of Labor (IZA) - 2014

In this paper, we describe a series of laboratory experiments that implement specific examples of a more general network structure and we examine equilibrium selection. Specifically, actions are either strategic substitutes or strategic complements, and participants have either complete or...
