2. Whateffect does high volatilityof financial markets haveon people's willingnessto
v v v v v v v v v v v
spend?
v
The high volatility of financial markets decreases people's willingness to spend,
v v v v v v v v v v
primarily because it directly affects their wealth, and also because high volatility
v v v v v v v v v v v v
indicates that there are considerable fluctuations in the prices of securities over a short
v v v v v v v v v v v v v v
time span. It increases insecurities about the future of an economy. Refer to Figure 2 to
v v v v v v v v v v v v v v v v

3. Explain the main difference between a bond and a common stock.
v v v v v v v v v v
A bond is a debt instrument, which entitles the owner to receive periodic amounts of
v v v v v v v v v v v v v v
money (predetermined by the characteristics of the bond) until its maturity date. A
v v v v v v v v v v v v v
common stock, however, represents a share of ownership in the institution that has
v v v v v v v v v v v v v
issued the stock. In addition to its definition, it is not the same to hold bonds or stock of a
v v v v v v v v v v v v v v v v v v v v
given corporation, since regulations state that stockholders are residual claimants (i.e.,
v v v v v v v v v v v
the corporation has to pay all bondholders before paying stockholders).

The recession in 2020, sometimes referred to as the COVID-19 Recession, was

induced by the coronavirus pandemic, lockdowns, and other preventive measures

taken by global economies to contain it have led to a severe contraction in the global
v v v v v v v v v v v v v v v v
economy.

8. Can you date the latest financial crisis in theUnited States or in Europe? Arethere
v v v v v v v v v v v v v v v
reasons to think that these crises might have been related? Why?
v v v v v v v v v v v
The latest financial crisis in the United States and Europe occurred in 2007–2009. At the
v v v v v v v v v v v v v v
beginning, it hit mostly the U.S. financial system, but it then quickly moved to
v v v v v v v v v v v v v v
Europe, since financial markets are highlyinterconnected. One specific wayin which
v v v v v v v v v v
these markets were related is that some financial intermediaries in Europe held
v v v v v v v v v v v v
securities backed by mortgages originated in the United States, and when these
v v v v v v v v v v v v
securities lost their a considerable part of their value, the balance sheet of European
v v v v v v v v v v v v v v
financial intermediaries was adversely affected.
