The lecture consists of two major parts:

  • Nonlinear Programming and Microeconomics and
  • Differential Equations, Optimal Control Theory and Macroeconomics.

    Chapters:

    (Preliminaries, Convex sets, Convex and concave functions, Quasi-convex and quasi-concave functions)

    2. Nonlinear Programming
    (Extreme points, Equality constraints, Inequality constraints, Non-negativity constraints, Constraint qualifications)

    3. Sensitivity Analysis
    (Comparative statics, Envelope theorem, Elements of microeconomic theory, Elasticity of factor substitution)

    4. Some Applications to Microeconomic Theory
    (Inferior inputs, Marginal and average costs, Marginal cost pricing, Factor prices, Supply of labour, Peak-load problem)

    5. Differential Equations and Elements of Nonlinear Systems
    (First- and second-order differential equations, Higher-order equations, Systems of equations)

    6. Some Applications to Macroeconomic Theory
    (Macroequilibrium, Money and growth)

    Quotation: I came to the position that mathematical analysis is not one of many ways of doing economic theory: It is the only way. Economic theory is mathematical analysis. Everything else is just pictures and talk.
    (R.E. Lucas Jr., 2001)
