Homework Answers

Answer #1

a.) When number of racers increases, the supply of racing events increase are there are more participants now. The demand is not affected by this. Hence:

D= 0, S= +, P = -, QS= +, QD= +

b.) When the number of events increases, again the supply of races increases. Hence:

D= 0, S= +, P = -, QS= +, QD= +

c.) When the consumers prefer swimming to running, the demand falls but the supply remains unchanged. Hence:

D= -, S= 0, P = -, QS= -, QD= -

d.) When price of a substitute event decreases, consumer will shift to the cheaper good. Therefore, Demand falls but supply remains unchanged. Hence:

D= -, S= 0, P = -, QS= -, QD= -

The general demand and supply functions given below describe the market for coffee. Demand and Supply are both functions of coffee's own price, P. Supply is also a function of the price of an input, coffee beans, Pb. Qd=D(P) Qs=S(P,Pb) a.) Use comparative statics to predict how the equilibrium price P*, changes when Pb increases. Start with the equilibrium condition, incorporating the fact that the equilibrium price, P*, is a function of Pb so that D(P*(Pb))=S(P*(Pb),Pb). Put a sign on...
