Microeconomics is the study of the economic behaviour of individual consumers, firms, and industries and the distribution of production and income among them. It considers individuals both as suppliers of labor and capital and as the ultimate consumers of the final product. It analyzes firms both as suppliers of products and as consumers of labor and capital.

3 Micro Concepts

Demand

A consumer's desire and willingness to pay for a good or service. For example, a consumer may be willing to purchase 2 lbs of potatoes if the price is $0.75 per lb. However, the same consumer may be willing to purchase only 1 lb. if the price is $1.00 per lb. The main determinants of the quantity one is willing to purchase will typically be the price of the good, one's level of income, personal tastes, the price of substitute goods, and the price of complementary goods. The quantity demanded is the amount of a certain product people are willing to buy at a certain price, and the relationship between price and quantity demanded is known as the demand relationship.

Supply

Discussion on Supply and Demand & the Concept of Elasticity

1. Mr. Capon is a butcher who recently raised the price of steak at his market from $1:50 a pound to $2:00 a pound. Correspondingly his sales dropped from 200 pounds per day to 100 pounds per day. Is the demand for steak at Capon's market elastic or inelastic? Explain. (show all works please) Given this circumstance, advise Mr. Capon on a pricing strategy to sell more or less.

2. Using average values find the coefficient of elasticity for the following:
Price..............Quantity
$45.................65,000
$55.................35,000

Explain your coefficient of elasticity.

3. The following relations describe the supply and demand for body lotions
Qd = 65,000 - 10,000 P
Qs = -35,000 + 15,000 P

Where Q is the quantity and P is the price of a body lotion, in dollars.
a. Find Qs, Qd, and shortage or surplus at prices; $6, $5, $4, $3, $2, and $1
b. What is the equilibrium price?
c. Using the law of Supply and Demand, comment on your market observation.

4. What is comparative static analysis? Given equilibrium of price and quantity, explain the impact of simultaneous shifts in demand and supply.
