Where QdBG is quantity demanded of boardgames. PBG is the
price of boardgames. PP is the average price of puzzles. M is
average annual household income. Pop is the population. Ad is the
annual dollars spent on advertising. R is the cost of capital to
the firm denoted by the average interest rate (in decimal format).
Suppose PP = $7, Pop = 1,000,000, M = $60,000, and Ad =
$10,000.
a) Calculate the quantity demanded of the boardgames if its
price is $9.
b) Calculate the POINT price elasticity of demand for the
boardgames at this price; Based on your
calculation, is the demand for boardgames inelastic or elastic
in this price range?
c) Calculate the POINT cross-price elasticity of demand for
puzzles; Based on your calculation, are puzzles and boardgames
considered to be substitutes or complements?
d) Calculate the POINT income elasticity of demand for
boardgames; Based on your calculation, are
boardgames considered to be a normal good or inferior good? A
necessity or luxury good?
e) Find the inverse demand function.
f) Find the total revenue function for boardgames: TR
=f(Q).
g) At what price and quantity would the boardgames maximize
its monthly revenue? Verify you found
a maximum.
h) Calculate the advertising elasticity of demand.
i. Is the response by consumers elastic or inelastic?
ii. What, if any, change in Total Revenues associated with
boardgames occurs due to the change
in advertising?
iii. Is the extra advertising dollars a good investment? Why
or why not? Is there any additional
information you would want to know before deciding to
advertise more or less?
