Publication bias under aggregation frictions : theory, evidence, and a new correction method

Furukawa, Chishio - 2019

This paper questions the conventional wisdom that publication bias must result from the biased preferences of researchers. When readers only compare the number of positive and negative results of papers to make their decisions, even unbiased researchers will omit noisy null results and inflate...

The fragility of meta-regression models in observational research

Bruns, Stephan B. - 2016

significant and theory-confirming estimates for publication. Meta-regression models were originally developed for the synthesis of … statistically significant and theory-confirming estimates. Each regression specification may possibly suffer from biases such as … authors of primary studies search for statistically significant and theory-confirming estimates, meta-regression models tend …

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...

Meta-analysis and publication bias : how well does the FAT-PET-PEESE procedure work? : a replication study of Alinaghi & Reed (Research Synthesis Methods, 2018)

Hong, Sanghyun - In: International Journal for Re-Views in Empirical … 3 (2019) 4, pp. 1-22

A meta-analysis is a tool for aggregating estimates of a similar "effect" across many studies. Publication bias is the phenomenon where literature is sample selected in favor of studies having statistically significant results and/or having estimates that satisfy pre-conceived expectations. A...

Non-standard errors

Bosch-Rosa, Ciril; Kassner, Bernhard - 2023

In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across...

Do better journals publish better estimates?

Slichter, David; Tran, Nhan - 2025

Are estimates typically closer to the true parameter value when those estimates are published in highly-ranked economics journals? Using 14,387 published estimates from 24 large literatures, we find that, within literatures, the mean and variance of parameter estimates have little or no...

The Properties of Model Selection When Retaining Theory Variables

Hendry, David F.; Johansen, Søren - 2011

theory model that specifies the correct set of m relevant exogenous variables, x{t}, within the larger set of m k candidate … the estimator distribution of the theory parameters. This strategy returns the theory-parameter estimates when the theory … is correct, yet protects against the theory being under-specified because some w{t} are relevant …

Pragmatism, Perspectival Realism, and Econometrics

Hoover, Kevin D. - 2011

Econometricians tend to hold simultaneously two views in tension with each other: an apparent anti-realism that holds that all models are false and at best useful constructs or approximations to true models and an apparent realism that models are to be judged by their success at capturing an...

Economic Methodology : Paradox of Ceteris Paribus (CP) Law in the Context of Sierra Leone

Jackson, Emerson Abraham - 2018

Research in the subject area of economics (as a social science) has defined its ontology of scientific investigation through economic methodology; a philosophical approach entailing the proviso of empirical evidence, and backed by an understanding of human interaction in their natural habitat....

Karl Popper's Superstitious Indeterminism : Is Statistics a Science?

Choi, Hak - 2016

This paper shows how a great philosopher, like Popper, can easily fall back to a common superstitious person. This paper also criticizes the general practice by statisticians to invent ad hoc method or manipulate data to suppress errors. Instead, this paper promotes the Xenophanes spirit of...
