News

I was invited to give a keynote presentation on the generalized method of moments estimation of linear dynamic panel data models at the inaugural Carpathian Stata Conference on July 27, 2026, in Cluj-Napoca. The respective xtdpdgmm Stata program was last updated to version 2.7.2 on July 17, 2025.

An updated discussion paper of my current work with Mehdi Hosseinkouchack and Matei Demetrescu on serial correlation testing in error component models with moderately small T is now available. I have recently presented this project at the 31st International Panel Data Conference in Exeter on July 7, 2026, and the Annual Scientific Conference of Romanian Academic Economists from Abroad in Cluj-Napoca on July 31, 2026. Our proposed tests are implemented in the new xtdpdserial Stata program, which was last updated to version 1.1.0 on July 17, 2026. Presentation slides from the 2024 UK Stata Conference are available online.

The 31st International Panel Data Conference was hosted by the University of Exeter in July 2026. I had the pleasure to be the head of the local organizing committee. Presentation slides for a post-conference workshop on dynamic panel data analysis in Stata are available on the conference website.

My new paper with Vasilis Sarafidis on spillovers and drivers of U.S. state population growth was published in a special anniversary issue of Spatial Economic Analysis. It provides an application for the spatial econometric methods implemented in our xtivdfreg Stata package.

In July 2025, Vasilis Sarafidis and I published an article documenting the new features of our xtivdfreg Stata package for estimating spatial dynamic panel data models with unobserved common factors in the Journal of Statistical Software. The Stata package was last updated on November 11, 2025, to version 1.5.4.

My paper with Melanie Krause on insights from commuter flows for regional dependencies and local spillovers appeared in the June 2025 issue of the Journal of Regional Science. Stata replication files are available.
