(a)
The different times to make a decision are at the end of October and at the end of November. They have to make a decision on whether to buy or defer it during the end of October. At the end of November, they have to make a decision whether to buy or not buy.
(b)
Supposing that Disneyland defers and waits to make a decision at the end of November and supposing further that the public health scenario improves from October to November.
If the above scenario happens, it is given that there is a 90 % probability that Disneyland will be open on NYE. If it is open on NYE, it is expected to generate $ 200,000 in revenue.
Therefore, expected revenues = ( probability of disneyland being open ) x ( revenues generated )
Expected revenues = 0.9 x 200,000
Expected revenues = $ 180,000
Cost of buying the merchandize = $ 150,000 ( since price increases in November end )
Profit = Expected revenues - costs
=> Expected Profits = $ 180,000 - $ 150,000
=> Expected Profits = $ 30,000
If Disneyland does not choose to buy, profits will remain zero.
Since the expected profits are higher if they bought the NYE themed goods, they should buy them. The expected profits in case they bought it would be $ 30,000.
(c)
If Disneyland elects to defer the decision from October to November
It has to decide either to buy or not buy in November end now.
If it decides not to buy, there is no profit or loss.
However, if it decides to buy at the end of November, its profits will depend on if Disneyland opens or not.
Now, Disneyland will decide to buy only if the situation improves in November. ( Because, if the situation does not improve in November end, the probability if it opening is only 30%. And expected revenues will be only $ 60,000 ( 0.3 x 200,000 ), which is less than the cost of goods ( $ 150,000 ). Therefore, it will choose not to buy if the situation stays in the current most restrictive tier. )
Probability of Disney buying in November = Probability of situation improving by November end = 0.4
Cost it incurs when Disneylad buys = $ 150,000
Profits if Disneyland opens = Revenes - costs = $ 200,000 - $ 150,000 = $ 50,000
Profits ( losses ) if Disneyland does not open = Revenues - costs = 0 - $ 150,000 = - $ 150,000
Probability of opening = 0.9 ( Since Disneyland will buy only if situation improves )
Probability of not opening = 0.1 ( Since Disneyland will buy only if situation improves )
Expected Profits = ( Probability of opening * profits if it opens ) + ( probability of not opening * profits if it does not open )
=> Expected Profits = ( 0.9*50000 ) + ( 0.1* 150000 )
=> Expected Profits = $ 30,000
However, this will happen only if the situation improves by November end.
Proababilty of buying = 0.4 ( Since Disneyland will buy only if situation improves )
Expected profits = ( probability of buying * expected profits when bought )
Expected profits = 0.4*30000
Expected profits = $ 12,000
(d)
If Disneyland buys the goods in October to November
Costs incurred if bought at end of October = $ 100,000
Probability of Corona virus situation improving = 40 %
Probability of situation staying in the current most restrictive tier = 60 %
Probability of park opening if situation improves = 90 %
Probability of park opening if it stays in the current most restrictive tier = 30 %
Probability of park opening = ( probability of situation improving * probability of park opening if situation improves ) + ( probability of situation staying in the current most restrictive tier * probability of park opening when situation stays in current restrictive tier)
Probability of park opening = ( 0.4 x 0.9 ) + ( 0.6 x 0.3 )
Probability of park opening = 0.54
Revenues generated when the park is open = $ 200,000
Expected revenues = probability of park opening x revenues generated when park is open
Expected revenues = 0.54*200,000
Expected revenues = $ 108,000
Costs if bought at end of October = $ 100,000
Expected Profits = Expected revenues - costs = 108,000 - 100,000
Expected Profits = $ 8,000
(e)
Disneyland should make the decision of defering to end of November since the expected profits are higher in that scenario.
