Document Summary

Market: two individuals (seller and a buyer) is considered a market, summation of individual demand curves. Change in demand: when the demand curve shifts right or left, cause by a change in the determinants of demand. Substitutes and compliments change in quantity demanded: cause by a change in the price. Supply curve: the law of supply. Shifting the supply curve left or right. Caused by the determinants of supply: change in quantity supply. A price change within the market you are talking about creates a move along the curve and not a move of the curve. Increase in supply vs. increase in quantity supplies. Increases in supply come from non price changes that increase the quantity supplied at every price. Increase in quantity supplied come from a raising of the price. Six non price determinants of supply: taxes, subsidies, resource costs, use of technology, number of sellers, expectations of future prices.

Section I: Supply & Demand Analysis (Chapter 3) In each of the following 10 questions, show what happens to the Demand, Supply, equilibrium price and equilibrium quantity of copper. Show an increase by use of +, a decrease with a -, and no change with 0 (thatâs a zero, not an O or o). Although in the real world, both supply and demand are constantly changing, in the model we are using here, only one curve shifts per problem. So, if demand goes + or -, supply will be 0, and vice versa. In no case will equilibrium price or equilibrium quantity be 0. You may want to sketch out the supply and demand curve analysis to help in answering the questions. You will also be required to identify which determinant (of demand or supply) has changed, thus causing the shift. Rather than actually writing in the determinant, fill in the blank with the number that corresponds to the relevant determinant, based upon the following list. You may want to refer to the lecture notes entitled Determinants of Demand & Supply in the COURSE CONTENTS section. For questions 1 - 10, refer back to this list. Some you may want to use more than once, some you won't use at all. Copy and paste this list to an MS Word document and then print it out if you don't want to keep scrolling back and forth between this list and the question you're trying to answer. Determinants of Demand: 1. Change in buyer tastes 2. Change in number of buyers 3. Change in income 4. Change in the prices of related goods (on the demand side) 5. Change in consumer expectations Determinants of Supply: 6. Change in resource prices 7. Change in technology 8. Changes in taxes and subsidies 9. Change in prices of related goods (on the supply side) 10. Change in producer expectations 11. Change in the number of suppliers. For example, if a rightward shift in the supply curve for an item were caused by an increase in the number of producers of that item, you would indicate this be entering 11 into the relevant blank. If the demand curve shifted to the left because people didn't like that item anymore (like mimeograph machines), you'd enter 1 into the blank. Q#1 President Trump signs into law a bill that says the U.S. government will subsidize the construction of new homes, office buildings, bridges, and other infrastructure projects requiring copper. Demand; Supply: Equilibrium Price: Equilibrium Quantity Exchanged; Which determinant changed?: Q#2 Non-capitalist economies around the world begin a phase of rapid economic development, construction and growth, becoming increasingly wealthy, as they begin to adopt more capitalist institutions, as in China, Russia, and the former communist countries of East Europe. Demand; Supply: Equilibrium Price: Equilibrium Quantity Exchanged: Which determinant changed?

The market demand curve

a. slopes upward.

b. is found by vertically adding the individual demand curves.

c. represents the sum of the quantities demanded by all the buyers at each price of the good.

d. represents the sum of the prices that all the buyers are willing to pay for a given quantity of the good.

When we move along a given demand curve,

all nonprice determinants of demand are held constant.

only price is held constant.

all determinants of quantity demanded are held constant.

d. income and price are held constant.

When the price of a good or service changes,

	a.	there is a movement along a given demand curve.
	b.	the demand curve shifts in the opposite direction.
	c.	the supply curve shifts in the opposite direction.
	d.	the demand curve shifts in the same direction.

: Do the following cause a change in demand (shift in demand curve), change in supply (shift in supply curve), change in quantity demanded (movement along demand curve) or change in quantity supplied (movement along supply curve)?

1) The market for Aquafina water. The price of Dasani increases.

2) The market for ground beef. The price of cow-feed increases

. 3) The market for hamburger patties. The price of hamburger buns decreases.

4) The market for pistols. Republicans fear that a democratic president will initiate new gun control laws making it more difficult to purchase guns.
