Mathematical Concepts

Lagrange Method
Optimization
Consumer Theory
Overlapping Generations Model (OLG)

Formulas

U(c1, c2) = ln(c1) + β ln(c2)
Budget constraint: w = c1 + c2 / (1 + r)
Lagrange function: L = ln(c1) + β ln(c2) + λ(w - c1 - c2 / (1 + r))
Consumption ratios: c2 = β (1 + r) c1
Consumption solutions: c1 = w / (1 + β), c2 = β (1 + r) w / (1 + β)

Theorems

Utility Maximization Principle
Lagrange Multipliers Method

Suitable Grade Level
