A firm operates a chain of coffee outlets in the city selling a coffee called “smart coffee”. The firm has estimated a regression model that suggests three variables are significant determinants of demand for “smart coffee”. The results obtained from the regression model is provided below.
Q=1000-60P+20DF+1.5A
Q: (dependent variable) is number of cups of “smart coffee” sold per week P: is the price in dollars of a cup of “smart coffee” |
DF: the price in dollars of a cup of a coffee called “daily fix” sold by a competitor |
A: the spending on advertising to promote “smart coffee” brand by the firm in dollars per week. |
(a). Interpret the meaning of each of the coefficients on the three variables (P, DF, and A)
(b). Suppose “smart coffee” is currently selling for $4 per cup. Compute the point price elasticity of demand for “smart coffee” at this price if the firm spend $4000 on advertising and “daily fix” sells for $3 per cup.
(c). The firm managers are considering lowering the price of “smart coffee” from the current $4 to match “daily fix” as a strategy to increase the market share as well as total revenue. Will this strategy achieve both these objectives? Briefly discuss.
A) coefficient on p= one dollar change in price of smart coffee , change quantity demanded by 60 in opposite direction.
Coefficient of Df=One dollar change in price of daily fix coffee price, increase quantity demanded of smart coffee by 20 in same direction.
Coefficient of A=one dollar change in spending on adversity of smart coffee, increase quantity demanded of smart coffee by1.5 in same direction.
B)Q=1000-60*4+20*3+1.5*4000=1000-240+60+6000=6820
Point elasticity of demand=(∆Q/∆P)*(P/Q)
∆Q/∆p=-60
Point elasticity=(-60)*(4/5820)=-240/6820=-0.035
C)When they match price of daily fix ,so they reduce their price =3.
New quantity demanded:Q=1000-60*3+20*3+1.5*4000=1000-180+60+6000=6880
Because quantity demanded and thus sale increase of smart coffee,so market share of smart coffee increased.
Total revenue with p=4,=4*6820=27,280
Total revenue with p=3,=3*6880=20,640
So decreasing price lead to decrease total revenue. So increasing total revenue objective couldn't achieve by this strategy.
