question
The elasticity of variable G with respect to variable S is defined as:
answer
the percentage change in variable G that results from a given percentage change in variable S.
question
The demand for good X is estimated to be Qxd = 10,000 − 4PX + 5PY + 2M + AX where PX is the price of X, PY is the price of good Y, M is income, and AX is the amount of advertising on X. Suppose the present price of good X is $50, PY = $100, M = $25,000, and AX = 1,000 units. What is the demand curve for good X?
answer
61,300
question

answer
0.52
question
The lower the standard error:
answer
the more precisely the parameter estimates the true values.
question
The price elasticity of demand is −2.0 for a certain firm's product. If the firm raises price, the firm manager can expect total revenue to:
answer
decrease.
question
The short-run response of quantity demanded to a change in price is usually:
answer
less than the long-run response.
question
When the price of sugar was "low," consumers in the United States spent a total of $3 billion annually on its consumption. When the price doubled, consumer expenditures actually INCREASED to $4 billion annually. This indicates that:
answer
the demand for sugar is elastic.
question
The demand for good X is estimated to be Qxd = 10, 000 − 4PX + 5PY + 2M + AX, where PX is the price of X, PY is the price of good Y, M is income, and AX is the amount of advertising on X. Suppose the present price of good X is $50, PY = $100, M = $25,000, and AX = 1,000 units. Based on this information, the income elasticity of good X is:
answer
0.82.
question

answer
It will increase 9 percent.
question
Which of the following provides a measure of the overall fit of a regression?
answer
F-statistic
question
When marginal revenue is zero, demand will be:
answer
unit elastic.
question
