What are the “Three Cs” that affect supply and demand and thus impact pricing?
In economics, what is the difference between demand and quantity demanded?
What does the law of demand state about the relationship between price and quantity demanded?
The price of a product or service is inversely related to the quantity demanded.
As the price declines, the quantity demanded increases; as the price increases, the quantity demanded declines.
What causes a shift of the demand curve?
A change in demand, caused by changes in the determinants of demand (which do not include changes in price), cause a shift of the entire demand curve. They include:
Price affects the quantity demanded, but it does not affect demand.
What is the difference between a change in demand and a change in quantity demanded?
What is the price elasticity of demand in economics?
The change in the quantity demanded of the good or service that occurs in proportion to a change in the price of the good or service.
How is the price elasticity of demand calculated according to the percentage method?
The percentage change in quantity demanded divided by the percentage change in price.
What does it mean if demand is price elastic?
The quantity demanded changes by a larger percentage than the associated change in the price, with an elasticity greater than 1.
What happens to total revenue if demand is price elastic and the price decreases?
Total revenue increases because the increase in quantity demanded more than compensates for the decrease in revenue per unit.
What is perfect price elasticity?
A situation where the quantity demanded is unlimited at one price but zero at any higher price.
When a good or service’s price elasticity is perfectly elastic, a perfectly competitive firm can sell an infinite number of units at the market price (or at any lower price) but at any higher price, it will sell nothing.
What is perfect price inelasticity?
A situation where any percentage change in price results in no change in the quantity demanded.
How does the midpoint method of calculating the price elasticity of demand address the weakness of the percentage method?
The midpoint method results in the same elasticity coefficient whether the price change is an increase or a decrease.
How is the price elasticity of demand calculated using the midpoint method?
Ed = {(Q2 − Q1) / [(Q2 + Q1) / 2] / (P2 − P1) / [(P2 + P1) / 2]}
In the midpoint method, the percentages of change used for the price and quantity are based on the averages of the beginning and ending amounts instead of on the beginning amounts as in the percentage method.
What are the classifications of levels of elasticity based on the elasticity coefficient?
How is the elasticity of demand interpreted when Ed < 1?
Inelastic or Relatively Inelastic. Any percentage change in price results in a smaller percentage change in the quantity demanded.
What is the relationship between price elasticity of demand and total revenue when demand is unitary elastic (the elasticity coefficient is 1.0)?
Total revenue is unchanged when the price either falls or rises when the elasticity coefficient is 1.0, but only if the elasticity is calculated using the midpoint method.
Define:
Market equilibrium
The point where the quantity demanded in the market is equal to the quantity supplied at the current price.
It is the point where the market demand curve for a product or service intersects with the market supply curve for the product or service.
What occurs when the equilibrium price is lower than a firm’s average variable cost?
The firm will shut down because it will lose more by continuing to sell its product or service than it would lose by selling nothing at all.
In a perfectly competitive market, how is the short-term equilibrium price determined?
It is the market price, with firms acting as price takers.
What is a natural monopoly?
It exists when economic and technical conditions permit only one efficient supplier in a location.
How does a monopolist determine the quantity to produce?
A monopolist will produce as many units as it can sell until the marginal cost of production exceeds the marginal revenue from selling one more unit.
What is the demand curve like for a firm in pure competition?
The demand curve is perfectly elastic, depicted by a horizontal line.
What is the effect of excess supply on market prices?
It exerts pressure for firms to reduce the price so they can sell more, causing the market price to fall.
What is the primary characteristic of a monopoly market structure?
A monopoly market structure is characterized by a single supplier of a product with high barriers to entry, resulting in higher prices and lower output levels compared to a perfectly competitive market.
