ma ma ma ma ma ma ma ma ma ma
A bond is a debt instrument, which entitles the owner to receive periodic amounts o
ma ma ma ma ma ma ma ma ma ma ma ma ma ma
f money (predetermined by the characteristics of the bond) until its maturity date. A
ma ma ma ma ma ma ma ma ma ma ma ma ma m
common stock, however, represents a share of ownership in the institution that has i
a ma ma ma ma ma ma ma ma ma ma ma ma ma
ssued the stock. In addition to its definition, it is not the same to hold bonds or stoc
ma ma ma ma ma ma ma ma ma ma ma ma ma ma ma ma ma
k of a given corporation, since regulations state that stockholders are residual claima
ma ma ma ma ma ma ma ma ma ma ma ma
nts (i.e., the corporation has to pay all bondholders before paying stockholders).

6. Can you think of a reason why people in general do not lend money to one another
ma ma ma ma ma ma ma ma ma ma ma ma ma ma ma ma ma
to buy a house or a car? How would your answer explain the existence of banks?
ma ma ma ma ma ma ma ma ma ma ma ma ma ma ma
In general, people do not lend large amounts of money to one another because of several
ma ma ma ma ma ma ma ma ma ma ma ma ma ma ma
mainformation problems. In particular, people do not know about the capacity of other p
ma ma ma ma ma ma ma ma ma ma ma ma ma
eople of repaying their debts, or the effort they will provide to repay their debts.
ma ma ma ma ma ma ma ma ma ma ma ma ma ma
Financial intermediaries, in particular commercial banks, tend to solve these problems
ma ma ma ma ma ma ma ma ma ma
maby acquiring information about potential borrowers and writing and enforcing contract
ma ma ma ma ma ma ma ma ma ma
s that encourage lenders to repay their debt and/or maintain the value of the collateral
ma ma ma ma ma ma ma ma ma ma ma ma ma ma
.

ate institutions or the general public to other institutions or people who need a loan.

8. Can you date the latest financial crisis in the United States or in Europe? Are ther
ma ma ma ma ma ma ma ma ma ma ma ma ma ma ma
e reasons to think that these crises might have been related? Why?
ma ma ma ma ma ma ma ma ma ma ma
The latest financial crisis in the United States and Europe occurred in 2007–
ma ma ma ma ma ma ma ma ma ma ma ma
2009. At the beginning, it hit mostly the U.S. financial system, but it then quickly
ma ma ma ma ma ma ma ma ma ma ma ma ma ma ma
moved to Europe, since financial markets are highly interconnected. One specific w
ma ma ma ma ma ma ma ma ma ma ma
ay in which these markets were related is that some financial intermediaries in Euro
ma ma ma ma ma ma ma ma ma ma ma ma ma
pe held securities backed by mortgages originated in the United States, and when t
ma ma ma ma ma ma ma ma ma ma ma ma ma
hese securities lost their a considerable part of their value, the balance sheet of Eur
ma ma ma ma ma ma ma ma ma ma ma ma ma ma
opean financial intermediaries was adversely affected.
