- Short-run and long-run cost analysis
- Supply curves derivation
- Market structures and firm behavior
This section helps explain how firms respond to market signals and technological changes.
3. Market Equilibrium and Welfare Analysis
Analyzing how markets reach equilibrium and their efficiency is crucial.
Topics include:
- Supply and demand models
- Market equilibrium and price determination
- Consumer and producer surplus
- Welfare theorems
- Efficiency and market failures
These concepts underpin discussions on policy interventions and resource allocation.
4. Game Theory and Strategic Behavior
Game theory introduces strategic decision-making among rational agents.
Key areas:
- Basic game representations (normal form)
- Nash equilibrium analysis
- Repeated and sequential games
- Strategic behavior in oligopolies and bargaining scenarios
Understanding strategic interactions is vital for analyzing markets with few dominant players.
5. Information Economics and Asymmetric Information
This section explores how information asymmetries affect markets.
Topics include:
- Adverse selection
- Moral hazard
- Signaling and screening
- Market mechanisms to mitigate information problems
These insights are essential in insurance, finance, and labor markets.
