Microeconomics/Oligopolistic Competition

Goals:
 * To explain how Duopoly and Oligopoly works
 * To explain price-based competition (Bertrand)\

To achieve these goals, we build on the definitions from Perfect Competition:


 * Profit
 * The Short Run (SR) v. The Long Run (LR)
 * Production Function
 * Principle of diminishing returns
 * Firm Production Decision
 * Profit Maximization Rule
