Name___________________________ Due date: 09/22/10 Assignment #2 MARKET EQUILIBRIUM In this exercise we are going to explore the equilibrium of a simple market in isolation— that is, we assume that prices and conditions in other markets do not influence this market (that is, we are looking at a single market for wheat, ceteris paribus ). By definition, in equilibrium the quantity supplied (Q s ) is equal to the quantity demanded (Q d ). The supply function of wheat (S w ) and the demand function of wheat (D w ) are both linear with respect to the price of wheat (P w ) as defined below: S w : Q sw = 12 + 2*P w D w : Q dw = 60 – 4*P w 1. Graph the relevant ranges of S w and D w . The relevant ranges are those values for which P w ≥ 0 and Q w ≥ 0. Label the curves S and D. Indicate the areas where we have shortage or surplus and point the equilibrium. 2. Use simple algebra to find the equilibrium price and equilibrium quantity traded.

At the equilibrium price, the quantity demanded is equal to the quantity supplied. At any other price (called a disequilibrium price) there is either a shortage or surplus. Calculate the amount of the shortage at a price of \$5.30. Show your work below: Answer: Amount of shortage 4. Now assume that the demand curve shifts, ceteris paribus , such that D w : Q dw = 80 4*P w Plot this shifted demand curve on your graph and label it as D*. What may have cause the shift in the demand function? 5. Use simple algebra to find the equilibrium price and quantity after this demand shift. Show your work below: Answer: Equilibrium price = Equilibrium quantity =...
