If bagels and cream cheese are complements, then what happens to the equilibrium price and quantity for cream cheese if the price of bagels increases? HINT: It will be useful to draw a diagram. SOLUTION: This shock is a + shift. The shock will shift the curve +. We then walk along the * curve from our previous equilibrium point on the graph to the new equilibrium point on the graph. As a result, the equilibrium price will + and the equilibrium quantity will This shock and the resulting new equilibrium is due to a change in

- Suppose the equation for demand can be expressed as P = 40 – 2Q. The equation for supply can be expressed as P = Q. Find the equilibrium price and quantity. Be able to draw the graph that illustrates your answer.This problem involves solving demand and supply equations together to determine price and quantity. a. Consider a demand curve of the form QD=-2P+20, where QD is the quantity demanded of a good and P is the price of the good. Graph this demand curve. Also draw a graph of the supply curve Qs =2P-4, where Qs is the quantity supplied. Be sure to put P on the vertical axis and Q on the horizontal axis. Assume that all the Qs and Ps are nonnegative for parts a, b, and c. At what values of P and Q do these curves intersect-that is, where does QD = Qs ? b. Now, suppose at each price that individuals demand four more units of output-that the demand curve shifts to QD - 2P+24. Graph this new demand curve. At what values of P and Q does the new demand curve intersect the old supply curve-that is, where does QD = Qs ? c. Now finally, suppose the supply curve shifts to Q's=2P-8. Graph this new supply curve. At what values of P and Q does QD=Q's? Show all working calculations and label garph with…From the graph, it is clear that the demand for gasoline is relatively (unit elastic, elastic, inelastic) and the supply for gasoline is relatively (unit elastic, elastic, inelastic). This is an example of a (positive or negative) supply shock and, referencing the graph below, is best represented by the shift (from curve 1 to curve 2 or from curve 2 to curve 1). If there's a price-gouging law in effect preventing gas stations from raising prices, then there will be an excess (supply, or demand) of _____ million gallons of gas. Suppose the government wants to alleviate the market imbalance. The best policy solution is to impose (import tariffs, production subsidies, import quotas, or purchasing limits) and the (cost or revenue) would be $______ million.

- The market price of pizzas in a college town decreased recently, and the students in an economics class are debating the cause of the price decrease. Some students suggest that the price decreased because several new pizza parlors have recently opened in the area. Other students attribute the decrease in the price of pizzas to a recent decrease in the price of hamburgers at local burger joints. Everyone agrees that the decrease in the price of hamburgers was caused by a recent decrease in the price of ground beef, which is not generally used in making pizzas. Assume that pizza parlors and burger joints are entirely separate entities-that is, there aren't places that serve both pizzas and hamburgers. The first group of students thinks the decrease in the price of pizzas is due to the fact that several new pizza parlors have recently opened in the area. On the following graph, adjust the supply and demand curves to illustrate the first group's explanation for the decrease in the price of…Consider the market for pens. Suppose that new medical concerns regarding graphite absorption have put pressure on schools to reduce pencil use in favor of pens. Further, the price of plastic, a major input in the pen production process, has dropped sharply. On the following graph, labeled Scenario 1, indicate the effect these two events have on the demand for and supply of pens. Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther.

Demand 0 Supply Demand Supply ?Suppose the price of apples (a complement to peanut butter) rises. At the same time, suppose the price of peanuts (which are used to make peanut butter) falls. Given these changes, you should expect to see: a decrease in the equilibrium price of peanut butter, but it's hard to say what will happen to the equilibrium quantity. an increase in both the equilibrium price and quantity of peanut butter. an increase in the equilibrium quantity of peanut butter, but it's hard to say what will happen to the equilibrium price. an increase in the equilibrium price of peanut butter, but it's hard to say what will happen to the equilibrium quantity.
- The market price of cheeseburgers in a college town decreased recently, and the students in an economics class are debating the cause of the price decrease, Some students suggest that the price decreased because several new burger joints have recently opened in the area. Other students attribute the decrease in the price of cheeseburgers to a recent decrease in the price of calzones at local pizza parlors. Everyone agrees that the decrease in the price of calzones was caused by a recent decrease in the price of pizza dough, which is not generally used in making cheeseburgers. Assume that burger joints and pizza parlors are entirely separate entities-that is, there aren't places that serve both cheeseburgers and calzones. The first group of students thinks the decrease in the price of cheeseburgers is due to the fact that several new burger joints have recently opened in the area. On the following graph, adjust the supply and demand curves to illustrate the first group's explanation for…The demand for coffee is given by the following equation, where QD�� stands for the quantity demanded and P stands for price. QD=100−4PQD= 100- 4P The supply of coffee is given by the following equation, where QS�� stands for the quantity supplied and P stands for price. QS=-10+2PQS= -10+ 2P For parts a-d, consider a graph of the demand and supply curves with price on the vertical axis and quantity on the horizontal axis. What is the slope of demand? Slope = At what price is quantity demanded equal to zero (this is, graphically, the vertical intercept of Demand)? P = What is the slope of supply? Slope = At what price is quantity supplied equal to zero (this is, graphically, the vertical intercept of Supply)? P =Use the results of your answers on both the Scenario 1 and Scenario 2 graphs to complete the following table. Begin by indicating the overall change in the equilibrium price and quantity after the shift in demand or supply for each shift-magnitude scenario. Then, in the final column, indicate the resulting change in the equilibrium price and quantity when supply and demand shift in the direction you previously indicated on both graphs. If you cannot determine the answer without knowing the magnitude of the shifts, choose Cannot determine. Change in Equilibrium Objects Scenario 1 Scenario 2 When Shift Magnitudes Are Unknown Price Quantity *option Increase, Decrease, Cannot Determine True or False: When both the demand and supply curves shift, the curve that shifts by the larger magnitude determines the effect on the undetermined equilibrium object.
