The following demand for potatoes in the United States was estimated for 1959-1973 period:
Q = 163.6 – 17.7Px + 9.3I
Where Q is the annual consumption of potatoes in pounds per
capita, or per person; Px is the average price in dollars per 100
pounds of potatoes; and I is the average per capita income
in thousands of 1958 dollars. If we imagine that this year,
Px = $3 and I = $2.344, calulate:
(a) The sales of potatoes this year.
(b) The elasticity of sales with respect to Px and
I.
(c) What would the sales be next year if Px was reduced
by 15% and I was increased by 20%?
(d) How much would income have to decrease if sales of potatoes
were to be 10% lower next year and price remained constant?

3. The Schmidt Corporation estimates that its demand function is Q=400 - 3P +41 +0.6 A where is the quantity demanded per month, P is the product's price in dollars), I is per capita disposable income in thousands of dollars), and A is the firm's advertising expenditures (in thou- sands of dollars per month). Population is assumed to be constant. a. During the next decade, per capita disposable income is expected to increase by $5,000. What effect will this have...
The demand function for bicycles in Super City has been estimated to be: Q = 2,000 - 5.5P + 15I Below is additional information concerning this Regression: Standard Error (SE) of the Intercept coefficient = 350 Standard Error (SE) of the price coefficient = 0.32 Standard Error (SE) of the Income coefficient = 0.70, R-Square = 0.64, Adjusted R-Square = 0.61, F-Statistic = 31.402, Q is quantity demanded per year, P is the price in dollars, and I is annual...
5 researcher estimated that the price elasticity of demand for automobiles in the United States is -1.2, while the income elasticity of demand is 3.0. increase the average price of automobiles by 5 percent, and they expect consumers' disposable income to rise by 3 percent. (a) If sales of domestically produced automobiles are 8 million this year, how many automobiles do you expect U.S. automakers to sell next year? (b) By how much should domestic automakers increase the price of...
4. Given the demand function Q=98.6-2.3P+3.1P,-2.1Y where Q, is the quantity demanded, Px is the price of the good itself in dollars, P is the price of a related good in dollars, and Y is average income (measured in thousands). If P $23, Ps $29, Y = $36, compute the value for Q C 1 point Using the information in part a, compute the cross-price elasticity (Eo) and determine if Py is describing a substitute or complement (round to 2...
1) A firm has estimated the following demand function for its product: Q = 58 - 2P + 0.10I + 15A where Q is Quantity Demanded per month in thousands, P is product price, I is an index of consumer income, and A is advertising expenditures per month in thousands. Assume that P = $10, I = 120, and A = 10. If so, the income elasticity of demand is a) .06 b) .18 c) .36 d) .86 2. Assume that...
Suppose the demand for gasoline in the United States is Q = 500.8 - 7.8P + 0.027Y - 19.6MPG, where Q is annual U.S. gasoline consumption in millions of gallons per day, P is the retail price of gasoline in $/gallon, Y is real disposable income in billions of 2012 dollars, and MPG is the fleet efficiency in miles per gallon. Assume in 2015 P = 2.50, Y = 14600, and MPG = 24.7. Note that MPG is the long-run...
The estimated demand function (Moschini and Meilke, 1992) for Canadian processed pork is Q = 161 − 20p + 20pb + 3pc + 2Y, where Q is the quantity in million kilograms (kg) of pork per year, p is the dollar price per kg, pb is the price of beef in Canadian dollars per kg, pc, is the price of chicken in dollars per kg, and Y is average income in thousands of dollars. What is the demand function if...
Using the supply and demand functions below, derive the demand and supply curves if Y = $55,000 and pc = $7. What is the equilibrium price and quantity of coffee? The demand function for coffee is Q = 8.5-p+ 0.01Y, where Q is the quantity of coffee in millions of pounds per year, p is the price of coffee in dollars per pound, and Y is the average annual household income in high-income countries in thousands of dollars. The coffee...
