7. Suppose that the Federal Reserve acts to increase the money supply. a. In the aggregate demand/aggregate supply diagram, will this monetary policy action work initially to shift the aggregate demand curve, the short-run aggregate supply curve, or the long-run aggregate supply curve? (Note: focusing for now on just the short-run effects of the change in policy, only one of these curves will shift.) b. In which direction will the curve you mentioned above shift: to the left or to the right? When the curve you mentioned above shifts, what will the short-run effect on the economywide level of prices be: with it rise, fall, or stay the same? d. When the curve you mentioned above shifts, what will the short-run effect on real GDP be: will it rise, fall, or stay the same? e. When the curve you mentioned above shifts, what will the short-run effect on unemployment be: will it rise, fall, or stay the same? 8. This last question builds directly on the previous one. Suppose that after observing the short-run effects of the increase in the money supply, the Federal Reserve decides not to reverse that policy action and, instead, leaves the money supply at its new, higher level permanently. a. Given that the Federal Reserve does not reverse its initial policy action, how will the economy move from the short-run equilibrium you described in question 7, above, to a new long-run equilibrium: through a shift in the aggregate demand curve, through a shift in the short-run aggregate supply curve, or through a shift in the long-run aggregate supply curve? (Note: focusing now just on the transition from the short run to the long run, only one of these curves will shift.) b. In which direction will the curve you mentioned above shift: to the left or to the right? C. Compared to its level in the initial long-run equilibrium, will the economywide level of prices in the new long-run equilibrium be higher, lower, or the same? d. Compared to its level in the initial long-run equilibrium, will real GDP in the new long-run equilibrium be higher, lower, or the same?1. Dale, Geraldine, Monroe, and Grover can split their time between fishing and gathering coconuts. Their production possibilities are reflected by the joint PPF below. Joint PPF (0,20) (10,20) (16,16) (20,10) (21,0) 15 25 coconuts a) What is the opportunity cost of producing the first 5 coconuts? b) What is the opportunity cost of producing the first 2 fish? c) If Geraldine has the second lowest opportunity cost of producing fish, what is her opportunity cost for gathering one coconut? d) How many fish can Geraldine catch if she spends all of her time fishing? 2. Nowhereland is an island economy with population of 4 - Alice, Bob, Catherine and David. Everyday there are two survival activities under the northerly Sea of Ferocity: catching jellyfish and collecting seaweed. Both activities involve open water diving, requiring the use of an oxygen tank. Thus, a special kind of capital called "oxygen tank" is used in the production of these two goods. Each person possesses a different amount of oxygen tanks. The following table shows how many oxygen tanks each person has and how many are needed to produce each unit of the delicacies: Alice Bob Cathy David Oxygen Tank Possessed (Tanks) 6 10 8 15 Catching Jellyfish (Tank/Jellyfish) 2 2 5 Collecting Seaweed (Tank/Seaweed) 3 5 NI 3 a) If everyone decides to catch jellyfish only, how many jellyfish can all of them produce? If everyone decides to collect seaweed only, how many seaweed can all of them produce? b) What are the opportunity costs of catching jellyfish for each person? What are the opportunity costs of collecting seaweed for each person? Put your answers in the following table. Opportunity Cost for a Jellyfish |Opportunity Cost for a Seaweed Alice Bob Cathy David c) Who has the absolute advantage in catching jellyfish/collecting seaweed? Who has the comparative advantage in catching jellyfish/collecting seaweed? d) Determine the acceptable range of trading price for 1 jellyfish in terms of number of seaweed. Determine the acceptable range of trading prices for 1 seaweed in terms of number of jellyfish. e) Label Seaweed (S) and Jellyfish (J) on the x-axis and y-axis, respectively. Give the equations for the PPFs of each person and plot separately. f) Draw the joint PPF for Nowhereland. Clearly mark and give the locations of the kink points. Write down the equation for each segment of the joint PPF.3. Use the demand and supply framework to qualitatively analyze the market in each of the scenarios given in a) through f). How would the demand and/or supply curves shift? (Leftward/rightwardo shift) What are the effects on equilibrium price and quantity? (Increase/decrease/ambiguous) Summarize the result in the following table format: Market Demand Curve Supply Curve Equilibrium Equilibrium Price Quantity a) Bubble Tea Fruit Smoothies Microwave C Meal Wisconsin Cheese jPhone 6 el Smartphone f) Exotic Cars N a) A recent study claims that the tapioca pearls in bubble tea are linked to increase risk for cancer, creating fear among consumers. b) In addition to the study report in a), you are also told that fruit smoothies are good alternatives to bubble tea. At the same time, you know that the extended summer has invigorated fruit harvests. c) Teaching assistants consider microwaveable meals an inferior good. This semester, they are greeted with bad news as the Department of Economics cuts their stipends by 15%. d) Wisconsin produces fine cheese using cow's milk; however, mad cow disease has wiped out half the population of cows in Wisconsin. e) Banana Inc. introduces the latest incarnation of its smartphone, the jPhone 6. A flood of consumers rush to order this famous smartphone. At the same time; however, the production line of Banana Inc. is plagued by riots, cutting production in half. () The economic slump and oil shocks have caused consumers to delay excessive spending, particularly, the purchase of exotic supercars. Automobile firms correctly anticipate the economic crisis and cut down production of exotic models. 4. Consider the market for gasoline in Dane County, Wisconsin. Units of quantity and price are in Thousands of Gallons and $/gallon, respectively. Suppose the gasoline demand is given by: Q" = 2000 - 200P where O" = Quantity Demanded and P = Price We have the following information about the linear supply function: Market research shows that for an increase in price by $1/gallon, quantity supplied increases by 100 thousand gallons; In addition, when the price is $1/gallon, 900 thousand gallons of gasoline are supplied to Dane County. a) Use the information to find the supply function, i.e., determine a and b in O' = a + bp where O' is Quantity Supplied and P is Price. (Hint: What is the equation of a line?) b) Plot the demand and supply curve with Quantity on x-axis and Price on y-axis. Clearly write the intercepts on both axes, and denote the area of consumer surplus and producer surplus. c) Find the equilibrium price and quantity and the value of consumer and producer surplus. Suppose there is a pipeline rupture in the Midwest, causing a gasoline shortage. Engineers have determined that pipeline capacity is reduced by 300 thousand gallons - meaning that, at every price level, there are 300 thousand fewer gallons of gasoline supplied to Dane County. d) Which curve (demand or supply) is shifted? Which direction (leftward or rightward)? e) Determine the equation (demand function or supply function) of the shifted curve. f) Draw the demand and supply curve after the pipeline rupture, clearly compare the shifts. g) Determine the equilibrium price and quantity and calculate the value of consumer and producer surplus after the pipeline rupture.5. The market for coffee beans is described by the following equations: 9' = 2P 8 g\" = is P a} Suppose the government sets a price ceiling at Sill Is there a shortage? Is there a surplus? b} The government lowers the price ceiling to $5. Describe the changes in shortagefsurplus. c} Now suppose a price floort'ceiling has been instituted1 which causes a surplus of 9 units. Is this a oor or a ceiling? What specific price would can-ate this surplus? 15. Consider a pumpkin market where the supply depends on the weather for the year. [It had-weather years1 supply is P = 59" + 2 ln good-weather years1 supply is P = 69' 53 The demand for pumpkins is {If = 25 iiP. Suppose that the government institutes a price support program to stabilise pumpkin prices at $32. The government promises farmers to buy or sell all that consumers desire or producers want to sell, at the price of $32. Assume the government has enough storage capacity to buy all that farmers grow and enough in storage to supply all that consumers demand. Assume storage costs $1 per pumpkin. a} How many pumpkins do consumers consume in good-weather years? h} How many pumpkins do consumers consume in bad-weather years? c} How much does the government spend in good-weather years? d} How much does the government earn in bad-weather years? Now suppose that instead of a price support prograrm the government begins subsidizing pumpkins. e} In bad-weadier years. the government spends a total of $123 on the subsidy to pumpkin growers. What is the per-unit subsidy? What was the target price? 7'. Suppose Latvia is a small, open economy that has a competitive steel market. The market supply curve is: Domestic supply: 9' = PA? and the market demand in Latvia is: Domestic demand: E = lid-P [in the world market, steel sells for 53!? a unit. Please note that graphs will be helpful in answering the following questions. a) How much steel does Latvia import? b) How much revenue will be raised by a tariff ofl per unit of steel? c) What is the deadweigbt loss associated with the tari? d) Suppose that instead of a tariff1 Latvia creates a quota limiting the number of imports to only 15 units. How much steel will be consumed in Latvia? Try to draw the supply curve that consumers in Latvia will face
