Econ 5

This monologue podcast is a lecture on microeconomic principles, specifically focusing on market structures and strategic decision-making. The lecture begins by reviewing a previous session's discussion on interest rate predictions and then introduces the concept of strategic decision-making through a card game example. The main body covers perfect competition, explaining how firms make pricing and output decisions in this market structure, including a detailed analysis of costs (fixed, variable, marginal, and average) and the concept of supply. The lecture then shifts to monopolies, demonstrating how firms determine optimal pricing and output, highlighting the social costs of monopolies (deadweight loss) and contrasting them with perfectly competitive markets. Finally, the lecture briefly touches upon monopolistic competition and oligopoly, using Taylor Swift's business model and the Loblaws bread-price-fixing case as examples. The lecture concludes with an introduction to game theory, using examples from the tire and beer industries to illustrate dominant strategies and Nash equilibrium.
