DESCRIPTION:Marion Hoffman\, “Modelling endogenous processes in mobility”\,
  IAST Lunch Seminar\, Toulouse: IAST\, March 13\, 2026\, 12:45–13:45\, roo
 m Auditorium 4 (First floor - TSE Building).\n\nAcross the social sciences
 \, mobility between social positions or physical locations is often modell
 ed as a sequence of independent choices. In practice\, however\, mobility 
 decisions are frequently interdependent: individuals respond to others’ mo
 vements\, giving rise to migration chains\, clustering\, and other collect
 ive patterns. This insight has motivated the representation of mobility sy
 stems as networks\, with locations as nodes connected by mobile individual
 s. Building on this perspective\, a recent statistical framework combines 
 network models and multinomial choice models to capture dependence between
  individuals’ mobility paths.\n\nIn the first part of the talk\, I show ho
 w this framework can be reformulated as a multinomial logit with dependent
  observations. This reformulation is useful for practitioners because it p
 rovides a transparent link between micro-level assumptions about how indiv
 iduals’ mobility decisions depend on one another and the resulting model s
 pecification. By making these assumptions explicit\, the approach clarifie
 s the interpretation of model parameters and strengthens the connection be
 tween statistical modelling choices and substantive theory.\nIn the second
  part\, I discuss the empirical value of this modelling approach. I examin
 e whether endogenous processes can account for structural patterns observe
 d in real-world mobility systems and to what extent analyses that assume i
 ndependent mobility decisions may lead to misleading results regarding pot
 ential drivers of mobility.
