Supply & Demand | Market Mechanism


The market mechanism is the tendency for prices to change until the quantity demanded equals the quantity supplied. Provide an explanation how the market adjusts to the market equilibrium when the price in the market is not originally set at the market equilibrium price.





















Your Answer:
Market equilibrium is a situation in which there is no surplus or shortage of output, and no pressure for the price to change. Free markets have a tendency to settle down in equilibrium.

When price is higher than the market equilibrium, a surplus develops. A surplus means that the quantity supplied is greater than the quantity demanded, and the market is out of equilibrium. Disequilibrium in this case puts downward pressure on price. As the price falls, the quantity demanded increases, as more consumers are willing and able to purchase the good. As the price falls quantity supplied falls, as firms are less willing to bring the good or service to market. Once the price falls to the point where the quantity demanded equals the quantity supplied, the market is in equilibrium with no tendency to change.

When price is lower than the market equilibrium, a shortage develops. A shortage means that the quantity demanded is greater than the quantity supplied, and the market is out of equilibrium. Disequilibrium in this case puts upward pressure on price. As the price rises, the quantity demanded falls, as fewer consumers are willing and able to pay for the good or service. Quantity supplied rises as the price rises, until the market equilibrium price is reached and the quantity demanded equals the quantity supplied.

  1. If I'm not mistaken, micro economics studying the behavior of consumers and producers, right.
    So, my question is how do consumer behavior and companies determine market prices and affect the supply & demand?
