one percent; increase; 1.50 units

one unit; increase; 1.50 units

Answer

one percent; quantity supplied; two units

one unit; quantity supplied; two units

one percent; quantity demanded; two percent

**Question 17**

Auto dealers slash prices at the end of the model year in response to deficient demand/excess inventory but restaurants facing the same problem slash production because

Answer

auto customers are less price sensitive than restaurant customers

price elasticity of demand (in absolute values) is higher for auto than restaurant customers

price elasticity of supply is lower in auto than in restaurants

restaurant food spoils quickly and is much more perishable

price elasticity of supply in autos is smaller than the absolute value of price elasticity of demand but the reverse is true for restaurants

**Question 18**

If demand were inelastic, then we should immediately:

Answer

cut the price.

keep the price where it is.

go to the Nobel Prize Committee to show we were the first to find an upward sloping demand curve.

stop selling it since it is inelastic.

raise the price.

**Question 19**

Suppose we estimate that the demand elasticity for fine leather jackets is .7 at their current prices. Then we know that:

Answer

a 1% increase in price reduces quantity sold by .7%.

no one wants to buy leather jackets.

demand for leather jackets is elastic.

a cut in the prices will increase total revenue.

leather jackets are luxury items.

**Question 20**

Even though insignificant explanatory variables can raise the adjusted R2 of a demand function, one should not interpret their effects on the regression when Answer

testing marketing hypotheses about the determinants of demand

analyzing inventory relative to capacity requirements

forecasting unit sales for operations planning

sales revenue reaches its peak
