DESCRIPTION:*This paper develops a dynamic model of addiction on networks\,
  where individuals' consumption is shaped by peer influence. We analyze the
  long-run effects of social interactions by characterizing steady-state con
 sumption as a function of both network position and forward-looking behavio
 r. We also examine the welfare implications of network structure and evalua
 te the effectiveness of various public policies aimed at reducing the deman
 d for addictive goods. In particular\, we study a key-player policy—model
 ed as a targeted rehabilitation program—that leverages the network’s in
 terpersonal influences to maximize impact.**Cultural integration has become
  a mainstay of policy discourse. Recent works point to two factors that pla
 y determinant roles in the cultural integration of a minority group : the n
 umber of cross-group linkages and the majority group’s response to the in
 tegration efforts of the minority. Motivated by these facts\, I study a two
 -stage model of integration. Individuals belong to either the majority or t
 he minority group and derive utility from their engagement with both cultur
 es during the second stage. In the first stage\, individuals can choose to 
 ‘specialise’ in their own culture\, increasing the utility they derive 
 from interactions with their own culture\, whilst decreasing that derived f
 rom the other. I show that individuals with a greater number of out-group r
 elations are less likely to ‘specialise’ and that the relative strength
  of the majority culture is crucial in determining whether an equilibrium i
 s ‘segregating’ or not.\\n\\nContact: Philippine Escudié: philippine.
