Preview
• Examine how financial markets work
– bond markets
– stock market
• Role of financial institutions in the economy
– commercial banks and investment banks
– asset management and insurance companies
• Role of money in the economy
– identifying links between monetary policy and the

Financial Markets and Institutions
• … help transfer funds from economic agents (i.e.,
households, firms, government, foreigners) who have an
excess of available funds to other agents who need funds to
finance expenditures
– HHs financing housing purchases (mortgages)
– Firms financing capital expenditures (corporate bonds,
stock issuance, bank loans)
– Governments financing budget deficits (Treasury
bills/bonds, Eurobonds)

Flow of Funds Through the Financial System
Copyright © 2019, 2016, 2013 Pearson Education, Inc. All Rights Reserved.
Functions of Financial System
• Channel funds from savers to borrowers
– more efficient allocation of capital
• Ease exchange of goods and services by providing means
of payment
– or provide the liquidity to convert financial assets to the medium of
exchange with low cost
• Provide insurance, diversification, risk management,
consumption smoothing benefits
– “Life-cycle”: borrow early in life, pay off mortgage and save for
retirement in middle age, dis-save when old.
• Provide information (esp. in secondary markets)

The Bond Market and Interest Rates
• A bond is a debt security that promises to make payments
periodically for a specified period of time.
– Treasury bills, government bonds
– Corporate bonds
• Interest rate is the (implied) compensation received by the
lender for the “rental of funds,” or equivalently, the cost of
funding for the borrower.

The Stock Market
• Stocks/shares/equity represent ownership in a company.
• Some corporations sell shares to the public to raise funds
and finance their activities
– Publicly-traded corporations vs. privately-held
– Secondary markets for stocks (stock exchanges)

Mutual funds and ETFs
• Buying and selling
individual stocks can be
costly and risky.
• Diversify risk through
mutual funds or exchange
traded funds (ETFs)
• Actively-managed funds
versus “passive” funds
that track a given index

Financial Institutions and Banking
• Financial intermediaries:
– Banks (depository institutions): accept deposits and make loans
– Other financial institutions: insurance companies, finance
companies, pension funds, mutual funds and investment
companies
• Financial innovation: the development of new financial
products and services
– ATMs, e-finance, mortgage-backed securities (MBS) etc.

Financial Crises
• Major disruptions in financial markets that are
characterized by sharp declines in asset prices and the
failures of many financial and nonfinancial firms.
– E.g., Financial crisis of 2007-08

Money and Monetary Policy
• Money plays an important role in facilitating transactions
– Medium of exchange role
• The amount of money/liquidity available in the economy
affects interest rates and asset prices, and is a crucial
determinant of business cycles (expansions/recessions).
• Monetary theory ties changes in the money supply to
changes in aggregate economic activity and to inflation
(changes in the overall price level).

Low inflation (or deflation) during recent
recessions despite large monetary stimulus
Money and Interest Rates
Short-term
• Liquidity effect: increase in money supply reduces the
“price” of obtaining funds, thereby lowering short-term
interest rates
Long-term
• Fisher effect: higher money supply (growth) may raise
inflationary expectations and inflation, and thereby increase
interest rates in the long run

• The Federal Reserve and other central banks control the

Fiscal Policy
• Monetary policy refers to the management of the money
supply and interest rates
– conducted by central banks (e.g., the Federal Reserve)
• Fiscal policy refers to the management of government
spending and taxation
– Budget deficit is the excess of gov. expenditures over its revenues
for a particular year
 Budget surplus is the excess of gov. revenues over its
expenditures for a particular year
– Budget deficits must be financed by new borrowing (which adds to
government debt)

Real vs. Nominal GDP
 GDP is the market value of all final goods and
services produced in a given period in a country.
 Nominal GDP measures these values using current
prices.
 Real GDP measures these values using the prices of
a base year.
CHAPTER 2
The Data of Macroeconomics
38
Real GDP controls for inflation
 Changes in nominal GDP can be due to:
 changes in prices
 changes in quantities of output produced
 Changes in real GDP captures changes in quantity of
output since real GDP is constructed using constant
base-year prices.

Answers
Nominal GDP multiply Ps & Qs from same year
2015: $46,200 = $30 × 900 + $100 × 192
2016: $51,400
2017: $58,300
Real GDP multiply each year’s Qs by 2015 Ps
2015: $46,200
2016: $50,000
2017: $52,000 = $30 × 1050 + $100 × 205

Aggregate Price Level
• The aggregate price level is a measure of average prices
in the economy.
• Three measures of the aggregate price level are
commonly used:
– The GDP deflator
– The PCE deflator
– The Consumer Price Index (CPI)

Calculating the Real Growth Rate and the
Inflation rate

RGDPt − RGDPt −1
gt = %∆Yt =
RGDPt −1
• Inflation rate (using GDP Deflator)

π t = %∆Pt =
