True/False/Uncertain. for each that the following statements, say whether it is true, false, or uncertain and explain your answer.

1. The is reasonable to intend the overcome price elasticity of demand for golf clubs and also golf balls to be positive.

Golf clubs and golf balls room complementary goods. This means that, together the price the golf clubs rises (a hopeful change), the usage of golf balls to reduce (a an unfavorable change). Overcome price elasticity of need is same to the proportion of these changes and also will be negative. The explain is false.

2. If the demand is perfect elastic, then a shift in the it is provided curve does not impact the equilibrium price.

True, because a perfectly elastic demand curve is horizontal. Therefore, no issue what the change is the equilibrium price will always remain the same. (See graph.)

3. The need curve because that autos is much more elastic 보다 the demand curve for Fords.

False. A Ford can be substituted by a various model. The is no as easy to discover a substitute because that a vehicle in general.

For this reason the need for your solutions will decrease, or transition to the left. The declare is false.

b. The need for your services becomes much more elastic. Among the components determining the price elasticity of demand for the good is the number of substitutes. Much more substitutes - much more elastic demand. The declare is true.

c. The cross-price elasticity of the need for your services with respect come the price charged by "Sunny Delight" is negative. These two goods (services) are substitutes. The cross-price elasticity that substitutes is positive, because as the price of among them increases, the need for (and thus the intake of) the various other one increases, too. The declare is false.

Short answer Question. 5. Initially Hans Johnson to be the only consumer in the market for "Casa de Econ" beer, developed by a tiny local brewery. As soon as the price that "Casa de Econ" six-pack varies in between $10 and also $20, the price elasticity that his individual need is equal to negative 1. Currently imagine that Hans has been cloned 4 times, and now we have 5 the same consumers in the industry for "Casa de Econ". What will take place to the price elasticity of market need in the price selection given above? will the demand become more price elastic, much less price elastic, or will certainly elasticity stay the same? describe your answer.

Since elasticity deals with relative changes, it doesn"t issue how plenty of consumers we have actually in the market as long as every one of them space same. (If the amount demanded for each the them alters by 50%, the would typical the amount demanded in the whole market will change by 50%, too.) so the price elasticity of demand will stay the same.
