severe limitations when analyzing any even moderately complex economic situation. Thus there is a need to study mathematical
methods vis-à-vis their applications in economics.
This course provides instruction in basic tools of mathematical economics and their applications to economic analysis. Techniques
discussed include elementary algebra, linear algebra, single and multivariable calculus, optimization, equilibrium analysis,
comparative static analysis and dynamic optimization. Depth of treatment of each topic will vary according to our needs.
