PPA ou PPP : parite de pouvoir d'achat ou parite de pouvoir de production?


  • Baldwin, John R.
  • Macdonald, Ryan


On examine dans cette etude les differents types de deflateurs qui sont utilises pour comparer les estimations des volumes de revenue et de la production nationale de divers pays. On y met de l'avant la these selon laquelle ces deflateurs doivent etre adaptes au concept specifique de revenu a l'etude. Si le concept de possibilite de depenser est utilise, on doit faire appel a un deflateur de pouvoir d'achat. Si un concept base sur la production est utilise, c'est alors un deflateur de pouvoir de production qui est de mise. Cette etude affirme que la pratique actuelle produit un deflateur hybride qui ne reussit pas a atteindre les deux objectifs lorsque les revirements des termes de l'echange sont importants et propose une solution.
