1.If the demand for corn increases due to its use as an alternative energy source, what will happen to the supply of corn's substitute such as soybean? Assume that, besides being substitutes for one another, corn and soybeans require the same raw material, such as the same farm land. Think about whether farmers will use their soybean farms to produce more or less corn. Explain, in economic terms [e.g. supply determinants], why this is so.
2.What will happen to the price of corn oil?
3.How does the price elasticity of demand for corn oil influence the quantity-demanded of corn oil and the Total Revenue earned by sellers of corn oil? Explain, using economic terms, why this is so.

1. If the demand for corn increases due to its sue as an alternative energy source, it will drive the price of factors of production (eg. labor and machinery) used to produce both corn and soybeans. That means that it would be more expensive to produce soy beans so the supply curve will shift to the right. Also, because now farmers have a chance to produce corn, they will, decreasing the production ...

Problems:

1)For each of the following cases, calculate the arc price elasticity of demand and state whether demand is elastic, inelastic or unit elastic

a) when the price of milk increases from $2.25 to $2.50 per gallon, the quantity demanded falls from 100 gallons to 90 gallons
b) when price of paper book falls from $7.00 to $6.50, quantity demanded rises from 100 to 150
c) when the rent on apartments rises from $500 to $550, the quantity demanded decreases from 1000 to 950 2)

2. For each of the following cases, calculate the point price elasticity of demand and state whether demand is elastic, inelastic or unit elastic. The demand curve is given by
Qd=5000-50Px

a) The price of product is $50
b) The price of product is $75
c) The price of product is $25

3. For each of the following cases, what is the expected impact on the total revenue of the firm. Explain your answer
a) Price elasticity of the demand is known to be -0.5, and the firm raises the price by 10%
b) Price elasticity of the demand is known to be -2.5, and the firm lowers the prices by 5%
c) Price elasticity of the demand is known to be 1, and the firm raises the prices by 1%
d) Price elasticity of the demand is known to be 0, and the firm raises the prices by 50%

4.The demand curve is given by
Qd=500-2Px
a) What is the total revenue function
b) The marginal revenue function is MR=250-Q
Graph the total revenue function, Demand curve and marginal revenue function c) c) At what price is revenue is maximised, What is the revnue at that point
d) Identify the elastic and inelastic portions of demand curve
