Oil rent, international imbalances and national dynamics.

Summary This study is an attempt to model international financial imbalances by taking into account the role played by oil-producing countries. In order to answer our problematic and to well define our subject, several complementary methods of modeling are used: The modeling of oil prices in "VECM", The modeling of fundamental equilibrium exchange rates "FFER", The modeling of financial imbalances with a theoretical model in Stock Flow Coherent "SFC", and with a model of world economy "Cambridge Alphametrics Model". Our thesis is composed of five chapters: Chapter 1 is an introduction, it deals with the problem of imbalances in the world economy and the role played by oil-producing countries in the formation of these imbalances. Chapter 2 is an analysis of the determinants of oil prices, which are increasing and highly volatile. Chapter 3, focuses on the exchange rates of oil exporting countries, and we have estimated the fundamental equilibrium exchange rate for these economies. Chapter 4, is an SFC model of payment imbalances between nations. Chapter 5 is a world economy model (CAM) using real data.
