“Real Assets” versus “Financial Assets”?
Examples of Financial Assets
• Debt (or “Fixed Income”)
– “Money market” instruments (< 1 year to maturity)
• Bank certificates of deposit
– “Capital market” instruments (1+ year to maturity)
• Bonds
• Common stock
– “Listed” (IBM, GE, GM)
– “Over-the-counter” (“penny” stocks)
• Preferred stock
• Derivative securities
– Futures, options, swaps
Real versus Financial Assets
• All financial assets (owner of the claim) are offset by
a financial liability (issuer of the claim).
• When we aggregate over all balance sheets, only real
assets remain.
• Hence the net wealth of an economy is the sum of its
real assets.

Economy
1-5
What do we mean by “allocation of capital”?
- Financial markets allow for the “allocation of capital”.
- Investor “capital” is the money they invest.
- The money “allocated” to companies (or governments) determines their future.
• Initial public offerings
– Microsoft example
– AT&T bonds example
– Mortgage-backed securities example
• Subsequent stock offerings
– Corporations sometimes issue more of their own stock
• Stock buybacks
– Corporations sometimes by back some of their own stock
• Financial markets: Prices are determined by buyers and sellers
What do we mean by “shifting your consumption”?
• Financial markets allow for “consumption shifting”.
• “Consumption” means using something up
– Example: spend $$ on food and gas.
• “Shifting your consumption” means you don’t have to spend
everything you earn today on things you will consume today.
– Example: most people borrow money to get started (education, home) and then
work and save, and then hope to retire and spend
• What is the impact of inflation?
– What if you save your money under your bed or in “risk-free” Treasury bills?
– What happens if people can’t trust savings accounts or “safe” investments?
Allocation of Risk
o Investors can choose a desired risk level
• Bonds versus stock of a given company
• Bank CD versus company bond
• Tradeoff between risk and return?
1-8
Financial Markets
• Informational Role of Financial Markets
o Do market prices equal the fair value estimate of a
security’s expected future risky cash flows?
o Can we rely on markets to allocate capital to the
best uses?
• What other mechanism could we use to
allocate capital?
• What would be the advantages and
disadvantages of another system?
1-9
• Separation of Ownership and Management
• Large size of firms requires separate
principals and agents
• Mitigating Factors
• Performance-based compensation
• Boards of directors may fire managers
• Threat of takeovers
• Corporate Governance and Corporate Ethics
• Businesses and markets require trust to operate
efficiently
• Without trust additional laws and regulations are
required
• Laws and regulations are costly
• Governance and ethics failures cost the economy
billions, if not trillions
• Eroding public support and confidence
• Corporate Governance and Corporate Ethics
• Accounting scandals
• Enron, WorldCom, Rite-Aid, HealthSouth, Global
Crossing, Qwest

industry

ethical standards

6%) and have not lost more than 13% of their value in
any one year.
