Chapter 3: Problem 51

Why would a free market never operate at a quantity greater than the equilibrium quantity? Hint: What would be required for a transaction to occur at that quantity?

Short Answer

Expert verified

A free market would never operate at a quantity greater than the equilibrium quantity because transactions require willing buyers and sellers. In a situation where the quantity supplied exceeds the quantity demanded, there is excess supply, leading to a lack of willing buyers at the current price. To sell this excess supply, producers would lower the price, which increases the quantity demanded and decreases the quantity supplied. This process continues until the market reaches the equilibrium point where the quantity demanded equals the quantity supplied.

Step by step solution

1. Understanding Equilibrium

Equilibrium is the price-quantity combination at which the quantity of goods demanded by consumers is equal to the quantity of goods supplied by producers. It is the point where the supply and demand curves intersect. At this point, the forces of supply and demand are balanced, and the market is considered stable.

2. Understanding Supply and Demand

In a market, supply refers to the quantity of a product that producers are willing to produce and sell at various prices. Demand refers to the quantity of a product that consumers are willing to buy at various prices. When the price is too high, the quantity demanded tends to be low, and when the price is too low, the quantity demanded tends to be high. The opposite is true for supply: when the price is high, the quantity supplied tends to be high, and when the price is low, the quantity supplied tends to be low.

3. Market Operations at Equilibrium

At equilibrium, the quantity demanded equals the quantity supplied. This means that producers are producing and selling the exact amount of goods that consumers are willing to buy at a specific price. In this situation, there is no excess supply, and there is no excess demand.

4. Market Operations at a Quantity Greater than Equilibrium

Suppose the market is operating at a quantity greater than the equilibrium quantity. This means that the quantity of goods supplied exceeds the quantity of goods demanded. In this situation, producers are producing and selling more goods than consumers are willing to buy at a specific price.

5. Transaction Requirements

For a transaction to occur in a market, there must be a willing buyer and a willing seller. In a situation where the market operates at a quantity greater than the equilibrium, there is an excess supply in the market, and some of these goods might not find willing buyers at the current price.

6. Adjustment towards Equilibrium

To attract more consumers and sell the excess supply, producers may reduce the price of the goods. As the price decreases, the quantity demanded by consumers will increase, and the quantity supplied by producers will decrease. This process continues until the price reaches a level where the quantity demanded equals the quantity supplied - the equilibrium point. In summary, a free market would never operate at a quantity greater than the equilibrium quantity because transactions require willing buyers and sellers. When the quantity supplied is higher than the quantity demanded, producers will have to lower prices to match demand, driving the market back towards equilibrium.
