Methods matter : p-hacking and causal inference in economics

Brodeur, Abel; Cook, Nikolai; Heyes, Anthony - 2018

The economics 'credibility revolution' has promoted the identification of causal relationships using difference-in-differences (DID), instrumental variables (IV), randomized control trials (RCT) and regression discontinuity design (RDD) methods. The extent to which a reader should trust claims...

The sources of researcher variation in economics

Huntington-Klein, Nick; Pörtner, Claus Chr. - 2025

We use a rigorous three-stage many-analysts design to assess how different researcher decisions—specifically data cleaning, research design, and the interpretation of a policy question—affect the variation in estimated treatment effects. A total of 146 research teams each completed the same...

Identifying program benefits when participation is misreported

Tommasi, Denni; Zhang, Lina - 2022

In cases of non-compliance with a prescribed treatment, estimates of causal effects typically rely on instrumental variables. However, when participation is also misreported, this approach can be severely biased. We provide an instrumental variable method that researchers can use to identify the...

Matching methods in practice : three examples

Imbens, Guido - 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...

Causal analysis after Haavelmo

Heckman, James J.; Pinto, Rodrigo - 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 …

Artifactual evidence of discrimination in correspondence studies? : a replication of the Neumark method

Carlsson, Magnus; Fumarco, Luca; Rooth, Dan-Olof - 2013

The advocates of correspondence testing (CT) argue that it provide the most clear and convincing evidence of discrimination. The common view is that the standard CT can identify what is typically defined as discrimination in a legal sense - what we label total discrimination in the current study...

Theoretical unification in justice and beyond

Jasso, Guillermina (contributor) - 2007

"The goal of scientific work is to understand more and more by less and less. In this effort, theoretical unification plays a large part. There are two main types of theoretical unification -- unification of different theories of the same field of phenomena and unification of theories of...

Discretionary measures of active labor market policy : the German employment promotion reform in perspective

Fertig, Michael; Schmidt, Christoph M. - 2000

This paper provides a preliminary assessment of recent reforms of German employment promotion policy. While several recent studies analyze the impact of measures of employment promotion for the case of Germany, no comparable study exists on the aggregate level, thus precluding any assessment of...

Evaluation of active labour market policy : methodological concepts and empirical estimates

Hujer, Reinhard; Caliendo, Marco - 2000

Persistently high unemployment, tight government budgets and the growing scepticism regarding the effects of active labour market policies (ALMP) are the basis for a growing interest in evaluating these measures. This paper intends to explain the need for evaluation on the micro- and...

The economics of replication

Müller-Langer, Frank; Fecher, Benedikt; Harhoff, Dietmar; … - 2017

Replication studies are considered a hallmark of good scientific practice. Yet they are treated among researchers as an ideal to be professed but not practiced. To provide incentives and favorable boundary conditions for replication practice, the main stakeholders need to be aware of what drives...
