Study Notes
Learning Objectives
- Compare perfectly competitive versus imperfect factor markets.
- Demonstrate profit maximization in imperfect product and factor markets.
Key Concepts
- Monopoly: A market structure with a single seller, leading to lower Marginal Revenue (MR) than Price (P).
- Marginal Revenue in Monopoly: MR is less than P due to the relationship between Total Revenue (TR) and Quantity (Q).
- Monopsony: A market structure with a single buyer of inputs, causing wage effects.
Market Comparisons
- In perfectly competitive markets, Price equals Marginal Revenue (P = MR).
- In imperfect markets (monopoly), Price is greater than Marginal Revenue (P > MR).
- Two major markets:
- Product Market: Marginal Revenue equals Marginal Cost (MR = MC)
- Factor Market: Marginal Revenue Product of Labor (MRPL) equals Marginal Factor Cost of Labor (MFCL)
Factor Market Cases
- Perfectly Competitive Product & Factor Markets:
- MVPL (Marginal Value Product of Labor) equals wage (w).
- Imperfect Product & Perfectly Competitive Factor Market:
- MVPL equals MFCL.
- Perfectly Competitive Product & Imperfect Factor Market:
- MRPL (Marginal Revenue Product of Labor) equals wage (w).
- Imperfect in both Product and Factor Markets:
- MRPL equals MFCL.
Profit Maximization
- Profit maximization condition: MRPL = MFCL.
- For monopsony, the condition is modified to reflect wage differentials and incentives for hiring.
Monopsony Analysis
- Wage Rate and Labor Demand:
- A monopsonist faces an upward-sloping labor supply, necessitating higher wages for additional labor.
- Graphical Representation shows wage differentials and quantity levels between monopsony and perfect markets.
Numerical Example
- Production Function: Q(L) = 25L - 0.1L²
- Output Price: P = 10
- Wage Rate Function: w(L) = 100 + 1.5L
- Marginal Product of Labor (MPL): Derived as MPL = 25 - 0.2L.
Profit Maximization Calculations
- Monopsony Level of Labor (L*M): Solved as L*M = 30 with corresponding wage wM = 145.
- Marginal Factor Cost (MFCL) and MVPL equality at L*M established at 190.
Perfect Competition Reference
- Comparatively, L*PCM calculated as approximately 42.875 and corresponding wage wPCM at 164.286.
Exploitation Rate in Monopsony
- Defined as δ = MVPL - wM, indicating potential inefficiencies in labor hiring.
Conclusion Insights
- Monopsonistic conditions lead to employment restriction (LM < LPCM) and wage repression (wM < wPCM).
