Matching Methods in Practice: Three Examples
Imbens, Guido W. - 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...

Econometric methods for causal evaluation of education policies and practices: a non-technical guide
Schlotter, Martin; Schwerdt, Guido; Woessmann, Ludger - 2010
Education policy-makers and practitioners want to know which policies and practices can best achieve their goals. But research that can inform evidence-based policy often requires complex methods to distinguish causation from accidental association. Avoiding econometric jargon and technical...

The credibility revolution in empirical economics: how better research design is taking the con out of econometrics
Angrist, Joshua D.; Pischke, Jörn-Steffen - 2010
This essay reviews progress in empirical economics since Leamer's (1983) critique. Leamer highlighted the benefits of sensitivity analysis, a procedure in which researchers show how their results change with changes in specification or functional form. Sensitivity analysis has had a salutary but...

A simple feasible alternative procedure to estimate models with high-dimensional fixed effects
Guimarães, Paulo; Portugal, Pedro - 2009
In this paper we describe an alternative iterative approach for the estimation of linear regression models with high-dimensional fixed-effects such as large employer-employee data sets. This approach is computationally intensive but imposes minimum memory requirements. We also show that the...

Forecasting errors: yet more problems for identification?
Contini, Bruno - 2009
Forecasting errors pose a serious problem of identification, often neglected in empirical applications. Any attempt of estimating choice models under uncertainty may lead to severely biased results in the presence of forecasting errors even when individual expectations on future events are...

Non-Farm Enterprise Productivity and Spatial Autocorrelation in Rural Africa: Evidence from Ethiopia and Nigeria
Owoo, Nkechi S.; Naudé, Wim - 2014
proximate farm and non-farm enterprises. To test for the presence and significance of such spatial autocorrelation we use data … (NGHS). We find evidence of significant spatial autocorrelation. Productivity of non-farm enterprises is widely dispersed … productive. In Nigeria, we find evidence for spatial autocorrelation at the individual enterprise level but not at the community …

Vote Influence in Group Decision-Making: The Changing Role of Justices' Peers on the Supreme Court
Mindock, Maxwell R.; Waddell, Glen R. - 2019
We consider the voting behavior of Supreme Court Justices, finding evidence of co-dependencies in their votes. Coincident with changes in the party imbalance of the Court over time, sharp discontinuities in these dependencies are evident. Overall, the patterns suggest a tradeoff between...

Econometric Mediation Analyses: Identifying the Sources of Treatment Effects from Experimentally Estimated Production Technologies with Unmeasured and Mismeasured Inputs
Heckman, James J.; Pinto, Rodrigo - 2013
This paper presents an econometric mediation analysis. It considers identification of production functions and the sources of output effects (treatment effects) from experimental interventions when some inputs are mismeasured and others are entirely omitted.
