A Primer on Walrasian Theories of Economic Behavior

The story of the body of economic analysis that were initiated by Léon Walras can be divided into developments before and after 1930. During the period before 1930 there were two phases to the story. The first was the seminal achievement of Walras. The second was the refinements and extensions made by the generation of Walrasian theorists that followed him. During the period after 1930 the story is also divided into two phases. One is the work that has been done on the type of Walrasian model in which there are no disequilibrium transactions. The other is the beginning of work on the behavior of general equilibrium systems in which disequilibrium transactions and production occur. These phases will be sketched very briefly with the objective of giving a beginner's introduction to some major aspects of the history of general equilibrium theory.
