# meta-analysis.cz > Methods, data, code, and papers for meta-analysis, by Tomas Havranek and Zuzana Irsova of Charles University, Prague, and their co-authors. The applied corpus is mainly economics and the social sciences; the methods and tools, among them MAIVE, are for use in any field. Each paper page links the full-text PDF and, for most papers, the dataset and estimation code. > Maintained by Tomas Havranek (in Czech Tomáš Havránek) and Zuzana Irsova (Zuzana Iršová, earlier work indexed as Zuzana Havránková) at the Institute of Economic Studies, Charles University, Prague. Both are Professors of Economics and Associate Editors responsible for meta-analysis at the Journal of Economic Surveys. Havranek sat on the European Research Council's Advanced Grant panel for economics and finance in 2020, the first Czech economist to do so. Irsova is the first author of the paper that introduced MAIVE (Nature Communications, 2025) and was elected to Academia Europaea in 2023.
