Pricing of Factors Under Imperfect Competition
1. Introduction
In a perfectly competitive market, factors of production (labor, capital, land) are paid according to their marginal productivity. However, under imperfect competition, factor pricing deviates due to the presence of monopsony power, trade unions, collusion, and market imperfections.
This blog explores how factor prices are determined under monopoly, monopsony, oligopoly, and bargaining conditions.
2. Factor Pricing Under Different Types of Imperfect Competition
🔹 (1) Factor Pricing Under Monopsony (Single Buyer of Factor Services)
🔹 What is a Monopsony?
A monopsony exists when a single employer dominates the demand for labor or other factors of production.
- Example: A coal mining company in a remote town is the only employer of workers.
🔹 Monopsony’s Impact on Factor Pricing
- In a competitive labor market, firms hire workers where wage = marginal revenue product of labor (MRPL).
- In a monopsony, the firm faces an upward-sloping labor supply curve, meaning it must raise wages to attract more workers.
- However, raising wages for new workers forces the firm to increase wages for all existing workers, increasing total labor costs disproportionately.
🔹 Hiring Decision in a Monopsony
- The firm hires labor where marginal factor cost (MFC) = MRPL instead of where wage = MRPL.
- This leads to lower employment and lower wages compared to perfect competition.
📌 Example:
- Amazon warehouses in rural areas may act as monopsonists, paying lower wages than in competitive labor markets.
✅ Conclusion: Monopsony power leads to underemployment and lower wages, reducing workers’ bargaining power.
🔹 (2) Factor Pricing Under Monopoly in Input Markets
🔹 What is a Monopoly in Factor Markets?
A monopoly in an input market occurs when a single supplier controls a key factor of production.
- Example: De Beers historically controlled the global diamond supply.
🔹 Monopoly’s Impact on Factor Pricing
- The monopolist restricts the supply of the factor to increase its price.
- Instead of pricing factors at marginal cost, they are sold at a higher monopoly price.
- This creates factor market distortions and higher production costs for firms using that input.
📌 Example:
- Intel’s dominance in microchip production gives it pricing power over PC manufacturers.
✅ Conclusion: A monopolist in a factor market raises prices and reduces efficiency, leading to higher consumer prices in downstream markets.
🔹 (3) Factor Pricing Under Bilateral Monopoly (Monopoly vs. Monopsony)
🔹 What is a Bilateral Monopoly?
A bilateral monopoly occurs when a single buyer (monopsony) and a single seller (monopoly) interact in a market.
- Example: A strong labor union negotiating with a single employer (e.g., airline pilots vs. airlines).
🔹 Factor Pricing in a Bilateral Monopoly
- The final wage rate depends on bargaining power and negotiation strategies.
- The wage is higher than monopsony wages but lower than monopoly-set wages.
📌 Example:
- United Auto Workers (UAW) vs. Ford Motors – The strong labor union pushes for higher wages, while the company tries to minimize labor costs.
✅ Conclusion: Wages in a bilateral monopoly depend on negotiation power, often leading to higher wages than a pure monopsony but lower than a competitive market.
🔹 (4) Factor Pricing Under Oligopsony (Few Buyers of Factor Services)
🔹 What is an Oligopsony?
An oligopsony occurs when a few large firms dominate the demand for a factor of production.
- Example: Supermarkets purchasing from farmers (Walmart, Tesco, Carrefour).
🔹 Effects on Factor Prices
- Oligopsonists collude or exert power to lower input prices.
- The factor price is kept artificially low, reducing supplier income.
📌 Example:
- Cocoa farmers in Ghana receive low prices because Nestlé, Mars, and Hershey’s dominate global cocoa purchasing.
✅ Conclusion: Oligopsony power depresses factor prices, harming small producers.
3. Government and Policy Interventions in Factor Markets
To correct distortions in factor pricing, governments may:
✔ Set Minimum Wages – Reduces monopsony power in labor markets.
✔ Enforce Antitrust Laws – Prevents collusion among oligopsonists.
✔ Support Trade Unions – Strengthens workers’ bargaining power.
✔ Impose Price Controls on Inputs – Prevents monopolies from overpricing essential factors.
📌 Example:
- EU’s Common Agricultural Policy (CAP) supports farmers by setting minimum prices for crops.
4. Conclusion
✔ Imperfect competition distorts factor prices, leading to lower wages (monopsony), higher input costs (monopoly), and suppressed supplier incomes (oligopsony).
✔ Bilateral monopoly cases depend on bargaining strength, leading to varied wage outcomes.
✔ Government interventions, labor unions, and regulatory policies help balance factor pricing distortions.
