My article with Vasilis Sarafidis on Estimating Spatial Dynamic Panel Data Models with Unobserved Common Factors in Stata finally appeared in the Journal of Statistical Software. Therein, we document new features for spatial models added to our xtivdfreg package. www.jstatsoft.org/article/view...
There is a new update to my -xtdpdgmm- #Stata package for the GMM estimation of linear dynamic panel data models, which introduces an option for estimating the optimal weighting matrix from alternative first-step residuals. www.kripfganz.de/stata/xtdpdg...
After #IPDC2025 is before #IPDC2026. I am happy to announce that the 31st International Panel Data Conference will take place in #Exeter (UK) at @universityofexeter.bsky.social @uofebusiness.bsky.social on July 6-7, 2026. Save the date! ipdc2026.org #Econometrics #Statistics #PanelData
This week's @exeter.ac.uk Weekly Bulletin features in its header a photo taken by me recently on our beautiful #Exeter campus. Happy #spring season!
There is an important update to my -xtdpdgmm- #Stata package for the GMM estimation of linear dynamic panel data models, which fixes an annoying bug with its -overid- option. www.kripfganz.de/stata/xtdpdg...

A long journey comes to an end: My paper with Melanie Krause on "Regional Dependencies and Local Spillovers: Insights from Commuter Flows" has finally found a home in the Journal of Regional Science. onlinelibrary.wiley.com/doi/10.1111/...
2025=(20+25)^2 2025=(\sum_{i=1}^9 i)^2 2025=\sum_{i=1}^9 i^3
Happy New Year!
It was nice to be back home at #Leipzig university where my academic career started. I presented my current research on serial correlation testing in error component models with moderately small T. For a preview, see my recent UK Stata Conference presentation: econpapers.repec.org/RePEc:boc:ls...
