⫸ In competitive markets _______ determine the allocation or
resources. Answer: Prices


⫸ Positive statements Answer: Clear and testable statements (with a
model)


⫸ Normative statements Answer: value judgements that are not
falsefiable


⫸ The demand function Answer: Q=D(P,Ps,Pc,Y) where Ps= price of
substitute and Pc= price of compliment


⫸ When you have two demand curves, how do you find the market
demand?
Q1=D1(p)
Q2=D2(p) Answer: Qmarket=Q1+Q2=D1(p)+D2(p)

, ⫸ The supply function Answer: Q=S(P,Pb) where Pb=price of inputs
that go into production. All factors not included in this function are
assumed to be held constant.


⫸ Market equilibrium Answer: Where Qd=Qs


⫸ Price elasticity of demand Answer: The price change in the Qd in
response to a given percentage change in P at a particular point on the
demand curve.


(dQ/dP)(P/Q)


⫸ T/F The higher the price, the more negative the elasticity of demand.
Answer: True


⫸ When elasticity of demand equals 0 the demand curve is: Answer:
perfectly inelastic (A 1% increase in p causes the Qd to become positive,
which is an infinite increase in quantity)


⫸ When elasticity of demand is between 0 and -1 the elasticity is:
Answer: inelastic


⫸ When elasticity of demand is between 0 and 1 the elasticity is:
Answer: elastic (a 1% increase in price causes more than a 1% fall in
quantity)
