Problem 1
Federal ethanol mandates require billions of gallons of ethanol be produced, purchased, and mixed into gasoline as part of an effort to reduce fossil fuel use and increase energy independence in the U.S. Suppose these ethanol mandates are removed from the market.
for ethanol?
for corn, which is the predominant source of ethanol production in the U.S.?
ethanol mandates?
high fructose corn syrup, a product made from corn. What steps might C&H take as a
result of the removal of the ethanol mandates?
Problem 2
Saxum Vineyard, in Paso Robles, CA, is one of the more than 8,000 wineries in the United States. While Saxum produces a number of different kinds of wine, they focus their production on Syrah (also known as Shiraz). Saxum sells their wines all over the United States. Suppose you manage a vineyard like Saxum and want to determine how much you should charge for your Syrah. Suppose the market demand function for Syrah is as follows.
QD = 200 – 38.18PO + 8.35PS – 2Pc + 10Inc + .8TS + .5M21
Where QD is monthly demand for bottle of Syrah (in millions), PO is the price of Syrah in the market, PS is the average price of substitute bottles of wine (other varieties), PC is the average price of a pound of cheese and is used to gauge the price of complimentary goods, Inc is average US income (in thousands), TS is the number of wine trade shows and competitions each year which firms can attend to market their wines, and M21 is the number (in millions) of millennials over the age of 21. This last variable is included to capture a change in consumer preferences; millennials are drinking wine at a much higher rate than previous generations.
The market for Syrah also has supply, produced by wineries similar to Saxum Vineyard and your winery, which can be stated as follows.
QS = -100 + 22.93PO – 5PPI – 10PS + 8Temp + 1Sup
Where QS is monthly supply of bottles of Syrah (in millions), PO is the price of Syrah in the market, PPI is the Producer Price Index (an index used to gauge changes in the costs of production in the US), PS is the price of substitute wines which could easily be produced instead of Syrah, Temp is the expected temperature during the harvest season for grapes, and Sup is the number of wineries supply Syrah in the market (in thousands).
Using the market supply and demand functions for Syrah given, fill in the template provided with the coefficients for each function. Using the information below, fill in the values for each of the variables except Price of Syrah. Then, set up your QD and QS to automatically calculate as you adjust the values for each variable.
Demand:
-Price of Substitutes: $18
-Price of Cheese: $15
-Income: $53,000
-Trade Shows/Competitions: $3
-Millennials = 43 million
Supply
-PPI: 111
-Price of Substitutes: $18
-Temperature: 60
-Number of Suppliers: 8,000
Now that you’ve set up your demand and supply functions, answer the following questions.
