Document Summary

Because you must add 30 to get to your target number of 40, and 30 is. Because you must decrease by 30 to get to your target number of ten, and. If prices decrease, people are likely to buy more. If prices increase, people are likely to buy less. Change in demand = shift of demand curve. Change in quantity demanded = shift of point on same curve. Demand in not just a point, it is a combination of points. Determinants of demand are: prices of related goods (complements and subsitutes, income and wealth, tasted and preferences, expectations. In production, there is a point where production costs may increase and thus it would cost more to produce extra units. Determinants of supply: cost of production, technology, typically, improved technology lowers the cost of production, so suppliers can make more products for the same amount of money, and supply can increase.

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?

b) moving downward (to the left) along the supply curve withlowerprices
c) less will be demanded at every price
d) more will be supplied at every price

Mary competes in a monopolistically competitive market. Suddenly, 5 new firms enter the market causing her perceived demand curve to shift. The following tables show her original and new demand curves and her cost information.

Assume that Mary can only choose from the quantities of output given in the table. By how will the quantity that she produces change after the new firms enter the market?
