12/15 CATS - Department of Economics
Spring Module

Principal Aims

To develop the notion of competitive equilibrium and the fundamental properties of competitive equilibria.

Principal Learning Outcomes

By the end of the module the student should be able to acquire a sense of the importance of strategic considerations in economic problem solving and the normative significance of competitive markets in obtaining Pareto optimal allocations via appropriate extensions of the commodity space. Learn that a few simple, intuitive principles, formulated precisely, can go a long way in understanding the fundamental aspects of many economic problems.

1. Foundations and Definitions for the Study of Walrasian Equilibrium: Commodities, Consumer preferences, Edgeworth boxes, Production

2. Efficiency of Allocation and Production
