MARKET POWER: The ability of buyers or sellers to exert influence over the price or quantity of a good, service, or commodity exchanged in a market. Market power largely depends on the number of competitors on each side of the market. If a market has relatively few buyers, but many sellers, then limited competition on the demand-side of the market means buyers tend to have relatively more market power than sellers. The converse occurs if there are many buyers, but relatively few sellers. This is also termed market control.

An increase in demand caused by one of the demand determinants.- Initial equilibrium market at price Po and quantity Qo
- Buyers acquire a sudden "appetite" for hot fudge sundaes.
A summary: - The demand curve shifts rightward.
- The initial equilibrium is no longer an equilibrium.
- The new equilibrium is at the intersection of the original supply curve with the new demand curve.
- New equilibrium price is P1 and new equilibrium quantity is Q1.
The six steps of market adjustment for an increase in demand:- A determinant changes. We have a greater appetite for hot fudge sundaes.
- A curve to shifts. The demand curve for hot fudge sundaes shifts rightward.
- A shortage or a surplus occurs. The increase in demand causes a shortage of hot fudge sundaes.
- The price changes. The price of hot fudge sundaes goes up.
- The quantities demanded and supplied change. The quantity supplied for hot fudge sundaes increases while their quantity demand is reduced.
- The market imbalance is eliminated and equilibrium is restored. The shortage of hot fudge sundaes is eliminated. The price is higher and the quantity exchanged is more.
