Summary

This course presents the problem of static optimization, with and without (equality and inequality) constraints, both from the theoretical (optimality conditions) and methodological (algorithms) point of view. Economics and financial applications will be provided.

Content

Topic 1 - Static optimization

Optimization programs with and without constraints. Examples of optimization problems in economic theory. Existence of solutions. Unconstrained optima: first-order and second-order conditions. Equality constraints and the Theorem of Lagrange. The Constraint Qualification. The Lagrange multipliers and their interpretation. Using the Theorem of Lagrange. Two examples from economics: Consumer and Producer Theory. One example from finance: optimal portfolios
and mean-variance analysis. Inequality constraints and the Theorem of Kuhn-Tucker. The Constraint Qualification. The Kuhn-Tucker multipliers. Using the Theorem of Kuhn-Tucker. An illustration from Consumer and Producer Theory. The general case: mixed constraints. Algorithms for univariate and multivariate nonlinear optimization (binary search, golden section search, Newton's method, steepest descent).

Topic 2 - Application to the choice under uncertainty

The investor's risk attitudes. Mean-variance criterium and expected utility criterium. Risk premium and certainty equivalent. Arrow--Pratt coefficient of risk aversion and corresponding utility functions. The investor's optimal portfolio with one risky asset. Optimal portfolio and wealth effect. Optimal portfolio with multiple risky assets. Portfolio expected return and variance. Portfolio diversification. The impact of different risk attitudes in portfolio choice.

Topic 3 - Application to the Estimation of the term structure of interest rates

The term structure of interest rates. Forward rates and the forward term structure of interest rates. Interpolation techniques and estimation methods: Ordinary Least Squares (OLS) vs Nonlinear Least Squares.

Keywords

Optimization program, equality and indequality constraints, Lagrange and Kuhn-Tucker theorems, algorithms, choice under uncertainty, mean-variance and expected utility criteria, term structure of interest rates estimation.
