Non-parametric inference for the effect of a treatment on survival times with application in the health and social sciences

Luna, Xavier de; Johansson, Per - 2009

In this paper we perform inference on the effect of a treatment on survival times in studies where the treatment assignment is not randomized and the assignment time is not known in advance. Two such studies are discussed: a heart transplant program and a study of Swedish unemployed eligible for...

Comments on the 2023 Draft Merger Guidelines: A Labor Market Perspective

Berger, David; Hasenzagl, Thomas; Herkenhoff, Kyle; … - 2023

The DOJ and FTC clarify the role of labor market power ("monopsony") in the 2023 draft merger guidelines. The draft … that a stricter threshold may be warranted in labor markets. The post-merger Herfindahl-Hirschman Index (HHI) that defines … monopsony power in the U.S. may warrant an even lower threshold. For example, merger simulations indicate that workers would …

Inconsistencies in reported employment characteristics among employed stayers

Bassi, Francesca; Padoan, Alessandra; Trivellato, Ugo - 2008

The paper deals with measurement error, and its potentially distorting role, in information on industry and professional status collected by labour force surveys. The focus of our analyses is on inconsistent information on these employment characteristics resulting from yearly transition...

Random Coefficient Panel Data Models

Hsiao, Cheng; Pesaran, Mohammad Hashem - 2004

This paper provides a review of linear panel data models with slope heterogeneity, introduces various types of random coefficients models and suggest a common framework for dealing with them. It considers the fundamental issues of statistical inference of a random coefficients formulation using...

General Diagnostic Tests for Cross Section Dependence in Panels

Pesaran, Mohammad Hashem - 2004

This paper proposes simple tests of error cross section dependence which are applicable to a variety of panel data models, including stationary and unit root dynamic heterogeneous panels with short T and large N. The proposed tests are based on average of pair-wise correlation coefficients of...

Panels with nonstationary multifactor error structures

Kapetanios, George; Pesaran, Mohammad Hashem; Yamagata, … - 2006

The presence of cross-sectionally correlated error terms invalidates much inferential theory of panel data models. Recently work by Pesaran (2006) has suggested a method which makes use of cross-sectional averages to provide valid inference for stationary panel regressions with multifactor error...

Inference with Difference-in-Differences Revisited

Brewer, Mike; Crossley, Thomas F.; Joyce, Robert - 2013

A growing literature on inference in difference-in-differences (DiD) designs with grouped errors has been pessimistic about obtaining hypothesis tests of the correct size, particularly with few groups. We provide Monte Carlo evidence for three points: (i) it is possible to obtain tests of the...

A Permutation Test and Estimation Alternatives for the Regression Kink Design

Ganong, Peter; Jäger, Simon - 2014

The Regression Kink (RK) design is an increasingly popular empirical method, with more than 20 studies circulated using RK in the last 5 years since the initial circulation of Card, Lee, Pei and Weber (2012). We document empirically that these estimates, which typically use local linear...

Practical Significance, Meta-Analysis and the Credibility of Economics

Stanley, Tom D.; Doucouliagos, Chris - 2019

Recently, there has been much discussion about replicability and credibility. By integrating the full research record, increasing statistical power, reducing bias and enhancing credibility, meta-analysis is widely regarded as 'best evidence'. Through Monte Carlo simulation, closely calibrated on...

Robust standard errors in transformed likelihood estimation of dynamic panel data models

Hayakawa, Kazuhiko; Pesaran, M. Hashem - 2012

This paper extends the transformed maximum likelihood approach for estimation of dynamic panel data models by Hsiao, Pesaran, and Tahmiscioglu (2002) to the case where the errors are crosssectionally heteroskedastic. This extension is not trivial due to the incidental parameters problem that...
