Neighbourhood Effects Research at a Crossroads: Ten Challenges for Future Research

van Ham, Maarten; Manley, David - Institute for the Study of Labor (IZA) - 2012

Neighbourhood effects research is at a crossroads since current theoretical and empirical approaches do not seem to be moving the debate forward. In this paper, we present a set of ten challenges as a basis for a new research agenda which will give new direction to the neighbourhood effects...

Robust Confidence Intervals for Average Treatment Effects under Limited Overlap

Rothe, Christoph - Institute for the Study of Labor (IZA) - 2015

Estimators of average treatment effects under unconfounded treatment assignment are known to become rather imprecise if there is limited overlap in the covariate distributions between the treatment groups. But such limited overlap can also have a detrimental effect on inference, and lead for...

Causal Analysis after Haavelmo

Heckman, James J.; Pinto, Rodrigo - Institute for the Study of Labor (IZA) - 2013

Haavelmo's seminal 1943 paper is the first rigorous treatment of causality. In it, he distinguished the definition of … Acyclic Graphs (DAG) used in one influential recent approach to causality (Pearl, 2000) and in the related literature on … causality, a central contribution of Haavelmo (1944). In general cases, DAGs cannot be used to analyze models for simultaneous …

Matching Methods in Practice: Three Examples

Imbens, Guido W. - Institute for the Study of Labor (IZA) - 2014

There is a large theoretical literature on methods for estimating causal effects under unconfoundedness, exogeneity, or selection-on-observables type assumptions using matching or propensity score methods. Much of this literature is highly technical and has not made inroads into empirical...

Policy Discontinuity and Duration Outcomes

den Berg, Gerard J. van; Bozio, Antoine; Costa Dias, Monica - Institute for the Study of Labor (IZA) - 2014

Causal effects of a policy change on hazard rates of a duration outcome variable are not identified from a comparison of spells before and after the policy change, if there is unobserved heterogeneity in the effects and no model structure is imposed. We develop a discontinuity approach that...

Education and Cancer Risk

Leuven, Edwin; Plug, Erik; Rønning, Marte - Institute for the Study of Labor (IZA) - 2014

There exists a strong educational gradient in cancer risk, which has been documented in a wide range of populations. Yet relatively little is known about the extent to which education is causally linked to cancer incidence and mortality. This paper exploits a large social experiment where an...

Health and Wealth of Elderly Couples: Causality Tests Using Dynamic Panel Data Models

Michaud, Pierre-Carl; van Soest, Arthur - Institute for the Study of Labor (IZA) - 2004

analyzes causality from health to wealth (health causation) and from wealth to health (wealth or social causation) for elderly … recently developed strategy using Granger causality tests of Adams et al. (2003, Journal of Econometrics) with tests for … causality in dynamic panel data models incorporating unobserved heterogeneity. While Adams et al. tests reject the hypothesis of …

Moving the Goalposts: Addressing Limited Overlap in Estimation of Average Treatment Effects by Changing the Estimand

Crump, Richard K.; Hotz, V. Joseph; Imbens, Guido W. - Institute for the Study of Labor (IZA) - 2006

Estimation of average treatment effects under unconfoundedness or exogenous treatment assignment is often hampered by lack of overlap in the covariate distributions. This lack of overlap can lead to imprecise estimates and can make commonly used estimators sensitive to the choice of...

The Effect of Disability on Labour Market Outcomes in Germany: Evidence from Matching

Lechner, Michael; Vazquez-Alvarez, Rosalia - Institute for the Study of Labor (IZA) - 2003

If labour market policies aimed at people with disabilities are effective, we should observe no significant difference in labour market outcomes between disable and non-disable individuals. This paper examines the impact of disability status on labour market outcomes using matching methods...

Nonparametric Tests for Treatment Effect Heterogeneity

Crump, Richard K.; Hotz, V. Joseph; Imbens, Guido W.; … - Institute for the Study of Labor (IZA) - 2006

A large part of the recent literature on program evaluation has focused on estimation of the average effect of the treatment under assumptions of unconfoundedness or ignorability following the seminal work by Rubin (1974) and Rosenbaum and Rubin (1983). In many cases however, researchers are...
