Correcting Publication Bias In Meta-Analysis: A Truncation Approach

Publication Bias in Meta-Analysis

Publication bias is the term for what occurs whenever the research that appears in the published literature is systematically unrepresentative of the population of completed studies. Simply put, when the research that is readily available differs in its results from the results of all the research that has been done in an area, readers and reviewers of that research are in danger of drawing the...

Adjusting for Publication Bias in Meta-Analysis

We review and evaluate selection methods, a prominent class of techniques first proposed by Hedges (1984) that assess and adjust for publication bias in meta-analysis, via an extensive simulation study. Our simulation covers both restrictive settings as well as more realistic settings and proceeds across multiple metrics that assess different aspects of model performance. This evaluation is tim...

Cumulative Meta-Analysis as a Publication Bias Method

Identifying and Correcting Publication Selection Bias in the Efficiency-Wage Literature: Heckman Meta-Regression

Publication selection bias represents one of the most serious challenges to the integrity of empirical economics. We develop Heckman regression methods to solve this potentially persistent problem and apply these meta-regression methods to seventy five empirical estimates from the efficiency-wage literature. Although many researchers find mixed or ambiguous support for the efficiency wage hypot...
