Assume That We Have a Demand Curve of the Form

question 102

Multiple Choice

Assume that we have a demand curve of the form: log(Q) = a - b log(P) + c log(I)
Where Q = quantity,P = price,I = income,and a,b,and c are positive constants.The income and price elasticities for the demand curve represented above are always

• A)equal to one.
• B)equal to zero.
• C)equal (i.e.,income elasticity always equals price elasticity).
• D)constant but not necessarily equal to one another.

Definitions:

Mean Square Error

A metric that measures the average of the squares of the errors—that is, the average squared difference between the estimated values and the actual value.

Total Sum

The aggregate value obtained by adding all the numbers in a set of values.

Observations

Data points or individual pieces of information collected during a study or experiment.

Confidence Interval

A range of values, derived from sample data, that is likely to contain the value of an unknown population parameter at a given confidence level.
