Economic Justification of Cooperatives

Two Key Elements: Market power and competitive yardstick.
Historical Context (Late 1800s/Early 1900s US Farmers):
- Farmers were numerous small sellers with limited options for selling goods.
- Railroad industry acted as a monopsonist (single buyer from many sellers).
Monopsony Explained:
- A market with a single buyer facing many sellers.
- The monopsonist (e.g., railroad) can set lower prices, extracting excess profits (economic rent) at the expense of sellers (farmers).
- Graphically, this is shown by a shift in the short-run supply curve (e.g., $S_{SR}$ ) resulting in a lower quantity and price for producers and a box representing the monopsonist's excess profits.
Cooperative Solution:
- Farmers form cooperatives by pooling resources and investments.
- This allows them to achieve economies of scale, lowering their long-run average cost ( $LAC$ ) per unit of output.
- By lowering costs and increasing output, cooperatives gain market power.
- They act as a competitive yardstick, holding the larger buyers (monopsonists) accountable to offer competitive prices.
Outcome for Farmers:
- The increased market power and competitive pressure from cooperatives lead to higher prices and increased quantity for their products.
- Profits are redistributed from the monopsonist back to the farmers.
