General Presentation

The general equilibrium theory studies the interactions among heterogeneous agents on commodity and financial markets. The course begins with an outline of the main properties of a competitive equilibrium in the classical Arrow-Debreu model (existence, efficiency, local uniqueness). The course then focuses on advanced questions arising from market imperfections and financial markets, such as externalities, increasing returns to scale and incomplete financial markets.

Key words: equilibrium, competition, market imperfections: externalities, financial markets.
