English Podcast starts at 00:00:00Bengali Podcast starts at 00:17:29Hindi Podcast starts at 00:25:39🎙️ Welcome to Revise and Resubmit — the podcast where great research meets great curiosity. I’m your host, and today, we’re diving into a question that echoes through the halls of spatial econometrics like a Shakespearean soliloquy:🧠 “To use, or not to use the Spatial Durbin Model? — that is the question.”👩🔬👨🔬 Penned by the brilliant Malabika Koley and Anil K. Bera, this award-winning article — yes, 🏆 Best Paper awarded by Spatial Economic Analysis in May 2025 — was published on November 9, 2023 in none other than the prestigious 🔝 Spatial Economic Analysis, an ABDC B Journal under the mighty umbrella of Routledge Taylor & Francis.📊 Now, the Spatial Durbin Model, or SDM for short, has been a crowd favorite in spatial econometrics. But here’s the twist: most researchers skip a crucial theoretical test before using it — a test that separates SDM from its cousin, the Spatial Error Model. Why? Because testing non-linear restrictions is... well, a headache. 😩But fear not — our authors have a fix. They propose a smarter, cleaner, linear way to test this restriction, using Rao’s score tests and a powerful enhancement from Bera and Yoon. 🚀 Their approach is robust, relies only on ordinary least squares (OLS), and has been put through the wringer with an extensive Monte Carlo simulation and two real-world datasets. Spoiler alert: it works really well. 🎯So now we ask...🤔 If we can test it more easily... should we still keep ignoring it?📚 Huge thanks to Malabika Koley, Anil K. Bera, and the publisher Routledge Taylor & Francis for making this groundbreaking work open-access — because science should be for everyone! 🌍💡✨ Don’t forget to subscribe to this podcast, Revise and Resubmit, on Spotify, Apple Podcasts, and Amazon Prime — and if you’re a weekend warrior of wisdom, check out our YouTube channel: Weekend Researcher! 🎧📺💥 Knowledge is power.
