What is elasticity? What is price elasticity of demand? What is price elasticity of supply?

Determine the price elasticity of demand, the cross-price elasticity of demand or the income elasticity in the following scenarios

a.  Consider the market for coffee. Suppose the price rises from $4 to $6 and quantity demanded falls from 120 to 80. What is price elasticity of demand? Is coffee elastic or inelastic?

b.  John’s income rises from $20,000 to $22,000 and the quantity of hamburger he buys each week falls from 2 pounds to 1 pound. What his income elasticity? Is hamburger a normal or inferior good?

c.  The price of apples rises from $1.00 per pound to $1.50 per pound. As a result, the quantity of oranges demanded rises from 8,000 per week to 9,500. What is the cross-price elasticity of apples? Are these goods substitutes or complements?

Is the price of chicken lower than the price of beef because beef is preferred over chicken (the demand factor), or because it is cheaper to produce chicken (the supply factor)? Is the cost of producing chicken lower than the cost of producing been because chicken is considered an inferior good?

1. Draw a price setting and demand curve for a situation where the buyer sets the price. Explain what it shows.

2. Draw a price ceiling and explain what it does. Be sure to include its effects on price and quantity.

3. List at least 5 reasons why an industry or company would want to vertically integrate.

1. Consider a price-taking firm operating in a market with price, p. The production function for the firm is FK,L=KαLβ. Where K is units of Capital and L is units of Labour. If the cost of each unit of capital is r and the cost of each unit of labour is w.
