Event Summary

On Wednesday, the Open Source Policy Center at AEI hosted its September Policy Simulation Library (PSL) meeting. PSL is an open-source software library for public policy decision-making and organizes monthly meetings for open-source policy modelers to present their projects to users and the general public.

The event featured a presentation from Lars Vilhuber, a senior research associate at Cornell University and data editor for the American Economic Association (AEA), on the history of, challenges to, and progress toward replicability in the social sciences. Dr. Vilhuber covered concrete steps that the AEA has taken to improve data and code transparency in its journals and offered suggestions on how researchers can maximize replicability and transparency in their work.

Event Description

Last year, Lars Vilhuber was appointed the inaugural American Economic Association (AEA) data editor to maximize reproducibility of research findings published in AEA journals. Dr. Vilhuber joins us to discuss the challenges to greater transparency and reproducibility in social science research and the steps that AEA has taken for curating research data and promoting reproducible research.

Everyone is welcome to the Policy Simulation Library DC meeting regardless of technical knowledge or experience, although please expect modeling code and results to be presented.

Peter Metz is a research associate at the Open Source Policy Center at AEI, where he focuses on developing, incubating, and promoting open-source modeling projects for public policy analysis. He is a core maintainer of two Policy Simulation Library (PSL) projects, Tax-Cruncher and PSL-Infrastructure, and makes technical contributions to the open-source Tax-Calculator model. Before joining OSPC, Mr. Metz was an economic consultant at Analysis Group. He received a bachelor’s degree in mathematics and economics from Washington University in St. Louis.

Lars Vilhuber is the executive director of the Labor Dynamics Institute at Cornell University, a faculty member in Cornell University’s Economics Department, and the American Economic Association’s data editor. His research interests relate to the dynamics of the labor market, including mass layoffs, worker mobility, and the relationship between labor and housing markets. He also has extensive expertise on the data needs of economists and other social scientists, having been involved in creating and maintaining several data systems designed with analysis, publication, replicability, and maintenance of large-scale code bases in mind. Dr. Vilhuber has an undergraduate degree in economics from Universität Bonn and a PhD in economics from Université de Montréal.
