1、The strong axiom of revealed preference requires that if a consumer chooses x when he can afford y; and chooses y when he can afford z; then he will not choose z when he can afford x.
A、对
B、错
2、If a consumer maximizes a utility function subject to a budget constraint and has strictly convex preferences, then his behavior will necessarily satisfy the weak axiom of revealed preference and the strong axiom of revealed preference.
A、对
B、错
3、The Laspeyres price index differs from the Paasche price index because the Laspeyres index holds prices constant and varies quantities while the Paasche price index holds quantities constant and varies prices.

4、Let A stand for the bundle (7,9);B stand for the bundle (10,5); and C stand for the bundle (6,6). When prices are (2,4); Betty chooses C. When prices are (12,3) she chooses A. Which of the following is true?
A、A is directly revealed preferred to
B、
B、A is indirectly revealed preferred to
B、
C、Cis directly revealed preferred to A、
D、None of the above
5、Remember that the Laspeyres price index uses the old quantities for the weights. In 1971, good x cost 3 and good y cost 1. The current price of good x is 3 and the current price of good y is 5. In 1971 the consumption bundle was (x,y) = (3,5). The cu
A、3.36
B、2.43
C、0.30
D、1.52
6、It follows from the weak axiom of revealed preference that if a consumer chooses x when he could afford y and chooses y when he could afford x; then his income must have changed between the two observations.
A、对
B、错

9、At prices (4,12); Harry chooses the bundle (9,4). At the prices (8,4); Harry chooses the bundle (2,9). Is this behavior consistent with the weak axiom of revealed preference?
A、Yes
B、No
C、It depends on his income.
D、We would have to observe a third choice to be able to say.
10、A student spends all of her income on pizza and books. When pizzas cost $3 each and books cost $10 each, she consumed 30 pizzas and 3 books per month. The price of pizzas fell to $2.90 each while the price of books rose to $11 each. The price change:
A、made her worse off
B、left her exactly as well off as before.
C、left her at least as well off as before and possibly helped her.
D、had the same effect as a $3 increase in her income.
