WebApr 13, 2024 · Migration models have evolved significantly during the last decade, most notably the so-called flow Fixed-Effects (FE) gravity models. Such models attempt to infer how human mobility may be driven by changing economy, geopolitics, and the environment among other things. They are also increasingly used for migration projections and forecasts. WebUsing this approach, we can write the estimating equation as. Yit = Xitβ + Zitc + ϵit. where c is an N × 1 vector of individual fixed effects. Deriving the least squares estimator for β in …
