Data and codes for meta-analysis

Browse and search these results on one page, filterable by field and phrased as the question each one answers.

One line per paper: the result the paper itself headlines. Definitions and samples differ across literatures, so check the source before reusing a number. Also as a spreadsheet: estimates.csv, which carries the sentence each figure came from.

Macroeconomics

• Effect of monetary policy on house prices: corrected for publication bias and misspecification, a 1.2% fall in house prices per 1-percentage-point policy rate rise, peaking after two years (correcting for publication bias alone gives 0.23%, but conditioning on best practice offsets it), based on 1,555 estimates from 237 impulse responses in 37 studies (Ehrenbergerova et al. 2023, IMF Economic Review) 10.1057/s41308-022-00185-5.
• Effect of structural reforms on economic growth: reforms in transition countries cost growth in the short run but raise it strongly in the long run, and that holds after correcting for publication bias, based on 60 studies with 537 estimates (Babecky and Havranek 2014, Economics of Transition) 10.1111/ecot.12029.
• Elasticity of intertemporal substitution in consumption: corrected for publication bias, 0.3-0.4 (micro estimates for asset holders; macro mean zero), based on 2,735 estimates from 169 published studies (Havranek 2015, Journal of the European Economic Association) 10.1111/jeea.12133.
• Elasticity of substitution between capital and labor: the meta-analytic estimate is 0.3 (best-practice specification; the mean reported estimate is 0.9), based on 3,186 estimates from 121 studies (Gechert et al. 2022, Review of Economic Dynamics) 10.1016/j.red.2021.05.003.

• The price puzzle (prices rising after monetary tightening): it disappears once publication and misspecification biases are corrected, and prices fall instead, bottoming out 0.33% below baseline six months after a 1-percentage-point rate rise, based on about 1,000 estimates from 70 studies (Rusnak et al. 2013, Journal of Money, Credit and Banking) 10.1111/j.1538-4616.2012.00561.x.
• Transmission lag of monetary policy to prices: the meta-analytic estimate is 29 months on average, but 25-50 months in developed economies against 10-20 in post-transition ones; the factor explaining that gap is financial development, with greater development meaning slower transmission (prices bottom out 0.9% below baseline after a 1-percentage-point hike), based on 67 published studies (Havranek and Rusnak 2013, International Journal of Central Banking) PDF.
• Why intertemporal substitution varies across countries: the meta-analytic finding is income and asset market participation explain most of the cross-country heterogeneity, based on 2,735 estimates from 169 published studies covering 104 countries (Havranek et al. 2015, Journal of International Economics) 10.1016/j.jinteco.2015.01.012.

• Electricity savings from daylight saving time: the best-practice estimate is essentially zero, 0.01% savings, against a 0.34% simple average of reported estimates (savings during the days DST applies; the paper finds no publication bias in this literature, so this is a methodological correction), based on 162 estimates from 44 studies (Havranek et al. 2018, Energy Journal) 10.5547/01956574.39.2.thav.

Meta-research methods

• Bias in meta-analyses of correlations: the methodological finding is that conventional fixed- and random-effects estimators are biased; the UWLS+3 and Hunter-Schmidt estimators correct this (Stanley et al. 2025, Research Synthesis Methods) 10.1017/rsm.2024.5.
• Bias in meta-analyses of partial correlations: the methodological finding is that all such meta-analyses are biased; the UWLS+3 weighted average corrects them (Stanley et al. 2024, Research Synthesis Methods) 10.1002/jrsm.1704.
• How to run a modern meta-analysis: a concise, nontechnical, step-by-step guide for practitioners, treating publication bias, p-hacking and heterogeneity as problems every meta-analyst must confront (Irsova et al. 2024, Journal of Economic Surveys) 10.1111/joes.12595.
• Sensitivity of meta-analysis results to outlier handling: the methodological finding is median shift at most 0.047 (Cohen's d); significance flips in 11.5% of cases (across four pre-registered outlier treatments and two estimators), based on 358 behavioral science meta-analyses (Havranek et al. 2026) PDF.
• Spurious precision in meta-analysis (the MAIVE estimator): the methodological finding is estimated precision can be p-hacked, which invalidates inverse-variance weighting; MAIVE instruments variance with sample size (Irsova et al. 2025, Nature Communications) 10.1038/s41467-025-63261-0.
• Whether multi-agent AI debate improves feedback on research papers: it does not; authors of 44 meta-analyses preferred a single frontier-model pass to two multi-agent debate tools, based on a pre-registered, identity-masked experiment (Havranek and Irsova 2026) arXiv:2607.14713.
