Suppose that banks are less able to raise funds and so lend less. Consequently, because people and households are less able to borrow, they spend less at any given price level than they would otherwise. The crisis is persistent so lending should remain depressed for some time. If nominal wages are sticky, which of the following helps explains the change in output? a. real wages fall, so firms choose to produce less b. real wages fall, so firms produce more...

Which of the following statements about a cost-of-living index is true? (a) A typical index overstates the effects of a price change because it ignores substitution in response to relative price changes. (b) A "chained" index generally states the true effect of price changes more accurately than does a more traditional (fixed-weight) index. (c) A cost-of-living index based on the general population (e.g., the consumer price index, or CPI) accurately captures the effects of price changes on specific demographic groups...
