The demand for good X is estimated to be QX d = 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, good X is
Correct answer(s):
- A normal good
The demand for good X is estimated to be QX d = 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
Correct answer(s):
- 0.82
The demand for good X is estimated to be QX d = 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, goods X and Y are
Correct answer(s):
- Substitutes
The demand for good X is estimated to be QX d = 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 cross-price elasticity between goods X and Y is?
Correct answer(s):
- 0.008
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, we know that the demand for good X is
Correct answer(s):
- Inelastic

The elasticity of variable G with respect to variable S is defined as
Correct answer(s):
- The percentage change in variable G that results from a given percentage change in variable S
A study has estimated the effect of changes in interest rates and consumer confidence on the demand for money to be: lnM = 14.666 +.021 lnC – 0.036 lnr, where M denotes real money balances, C is an index of consumer confidence, and r is the interest rate paid on bank deposits. Based on this study, a 5% increase in interest rates will cause the demand for money to:
Correct answer(s):
- Drop by.18%
