Introduction
I’m saving for retirement. Should I
deposit into bank, mutual fund, direct stock market investment?
I want a new motorbike. Should I use
saved cash, borrow money?
I’m thinking about starting a new business
Is it worth doing? How much money do I need to start? Where can
I get money?
1. Defining Finance
Finance is the study of how people allocate scarce resources
over time (Bodie and Merton)

"Finance" Bodie and Merton
FinancialTransaction
• Spread out through space and over time
• Risk – Return trade off
• Assets used for the transactions is either cash or
financial assets
Real Assets versus Financial Assets
Asset: any possession that has value in an exchange
A real asset is used to produce goods and services and thereby
generate cash flow
E.g: machine, building, equipment, land/real estate
A financial asset is a claim against a firm, government or
individual for future expected cash flows.
E.g: bonds, preferred stocks and common stocks.
Financial assets
Main properties:
Rate of Return : expected return
Risk: credit risk, market risk
Liquidity: Easy convertibility into cash with little or no
loss of value

Financial Assets
Three broad types of financial assets:
Fixed-income securities
Equity securities
Derivative securities
2. Five Core Principles of Finance
-Time has value
- Risk requires compensation
- Information is the basis for decisions
- Markets determine prices and allocate resources
- Stability improves welfare

4. Financial Decisions of Firms
Business Firms
entities whose primary function is to produce goods and
services
they vary widely in size from part-time businesses run from a
spare room, to giant corporations (e.g. Mitsubishi or General
Motors) with hundreds of thousands of employees, and an even
larger ownership
Forms of business organization
Three major forms in the U.S
1. Sole proprietorship
2. Partnership
3. Corporation
Financial Decisions of Firms
When you start your own business, what financial decisions
do you have to take?
1. What long-term investments should we take on?
2. What are the sources of long-term financing?
(equity, loans)
3. How should we manage everyday financial
activities – managing working capital? (collecting
receivables, paying suppliers etc.)
Financial decisions
Investment decision – how much to invest and in what assets?
Financing decision – where is money from in order to finance
long-term investments?
Working capital decision

"Finance" Bodie and Merton
Financial Decisions of Firms
The Capital Budgeting Process – Investment Decision
The preparation of a plan for acquiring factories, machinery,
research laboratories, show rooms, warehouses, and human
assets to implement the strategic plan
The basic unit of analysis is the investment project. Investment
projects are identified, triaged, and implemented in the capital
budgeting process
Financial Decisions of Firms
The Financing Process
Once a new set of approved projects has been identified, it must
be financed with retained earnings, stock, bonds, et cetera
Capital structure is the amount of the firm’s market value
allocated to each category of issued securities. It determines
ownership and risk level of the firms future cash flows
Capital structure’s unit of analysis is the firm as a whole (not an
investment project )
Financial Decisions of Firms
Working Capital
all firms (including highly profitable ones) that do not pay
sufficient attention to working capital management may be
seriously damaged by the resulting
loss of investor and creditor confidence
delayed in investment schedules
sub-optimal temporary finance
unscheduled sale of the firms assets
5.The Financial System
FIGURE

"Finance" Bodie and Merton
5.1.What is the Financial System?
A FinancialSystem is comprised of
markets, intermediaries, service firms and other institutions
used to carry out the financial decisions of households,
business firms, and governments
The household is the primary provider of funds to businesses and
government.
Households must accumulate financial resources throughout their
working life times to have enough savings (pension) to live on in their
retirement years
Financial intermediaries transform the nature of the securities
they issue and invest in
Banks, trust companies, credit unions, insurance firms, mutual funds
Market intermediaries simply help make markets work
Investment dealers
Brokers
The Financial System
Financial Intermediaries: a firm whose primary business
is to provide financial services and financial products
- Banks and other deposit-taking institutions: checking accounts,
loans,CDs …
- Insurance companies: term life insurance...
- Pension Funds
- Mutual Funds
Spending Sectors
Household
Business Firms
Government
Foreign Sector
• SURPLUS SPENDING
UNITS
• DEFICIT SPENDING
UNITS

"Finance" Bodie and Merton
Surplus Spending Unit (1)
Has more cash income flow than expenditure on
consumption and real investments in a period of time.The
surplus is then allocated to the financial sector.
Other terms for surplus unit are saver, lender, buyer
of financial assets, financial investor, supplier of loanable
funds, buyer of securities.
Surplus Spending Unit (2)
The surplus unit may buy financial assets, hold more
money, or pay off financial liabilities issued earlier when in a
deficit situation
The household and foreign sectors are usually a surplus
sector
Deficit Spending Unit (1)
Has more expenditures on consumption and real
goods (investment) in the real sector than income during a
period of time
The deficit unit must participate (borrow) in the
financial sector to balance cash inflows with outflows
Deficit Spending Unit (2)
Other terms for deficit expending unit are borrower,
demander of loanable funds, and seller of securities.
The deficit spending unit may issue financial
liabilities, reduce money balances, and sell financial assets
acquired previously when in a surplus situation

5.2The Flow of Funds
Funds may flow from the surplus unit to the deficit unit
in three ways:
Directly meet
Through market intermediaries (or markets)

Fund Flows via Intermediaries
Holders of surplus funds may use an intermediary, such as a
bank, to invest them. The bank receives the surplus funds, say
as 90-day deposits, and adds them to the bank’s assets (creating
a bank liability). Money is fungible, so the corresponding loan
can not be identified

Fund Flows via Intermediaries and Markets
Sometimes the intermediary itself has surplus funds, and invests
them in the market or another intermediary
A bank that borrows and invests in the money market can
increase its flexibility, reduce its risks, and turn a profit
Eventually, the surplus funds are consumed by a deficit unit

Fund Flow via Markets and Intermediaries
Intermediaries such as General Motors Acceptance
Corporation issue commercial paper to finance car loans and
leases made to households needing a car
In this case, the paper has a shorter maturity than the
loan, leading to a risk
