Answer:
a) 4 dollar
b) 1 dollar
c) 3 dollar
d) FALSE the decrease would have been greater.
Explanation:
8 dollar sales price - 4 dollar received from producer = 4 dollar tax on beer per case
burden for consumer per case: from 7 to 8 = 1 dollar per case
the produced will have to burden 3 dollar per case
to an increase of 1/7
the demand decreased 6/40
price elasticity of demand (-6/40) / (1/7) = -1.05
If tax was levied on consumers then price would go from 7 to 11
X / (4/7) = -1.05
X = -0.6
-a/40 = -0.6
-a = 24
The demand would decrease by 24 billon cases which is much higher than the 6 billion it decrease from the produced tax.
