Chapter 11 – The Economics of Financial Intermediation
Teaching Tips/Student Stumbling Blocks
To emphasize the five functions performed by financial intermediaries (i.e., they
pool the resources of small savers; they provide safekeeping and accounting
services as well as access to the payments system; they supply liquidity; they
provide ways to diversify small investments (reducing their risk); and they collect
and process information in ways that reduce information costs) have students list
the various financial intermediaries with which they do business. Which
function(s) are performed by each?
Have students consider the factors that might affect their credit scores. Students
may not realize that a credit card with no balance but which has a credit amount is
treated exactly as if that amount was owed; this is a good example of how a lender
deals with moral hazard (i.e., the borrower could go out tomorrow and charge that
amount to the credit card). On the other hand, lenders also look at how much of
the total credit a person has is “available.”
Features in this Chapter
Your Financial World: Your First Credit Card
The interest rate on your first credit card is likely to be very high because you have no
credit history, and the company issuing the card will assume the worst. This is adverse
selection at its worst. After a while, when you establish a track record, you should be
able to get a card at a lower rate.
Applying the Concept: The Madoff Scandal
The fraud perpetrated by Bernard Madoff stands out as extraordinary, though it was an
ordinary Ponzi scheme. Why do such schemes work? They work for a number of
reasons, including investors failing to screen and monitor the managers of their
investments, and public respectability of those managers. Further, sometimes the
government agencies responsible for overseeing the managers fail to detect the scheme.
Your Financial World: Private Mortgage Insurance
If you try to buy a house with a down payment of less than 20 percent of the purchase
price, the lender may require you to buy private mortgage insurance (PMI), which insures
the lender in the event that the borrower defaults on the mortgage. You can cancel the
insurance when the amount you owe on your mortgage falls to less than 80 percent of the
value of your home; this can happen as a result of your making payments to reduce the
principal on the loan or as a result of increases in home values.
