I. Introduction – Financial Markets

Individuals may desire to consume amounts different from their incomes.

Financial markets facilitate this.

The interest rate is the price of money in borrowing or lending transactions.

3

Introduction – Financial Markets

The job of balancing the supply of and demand for loanable funds is taken by the money market.

When the quantity supplied equals the quantity demanded, the market is in equilibrium at the equilibrium price.

4

II. Perfect Markets and Arbitrage

For simplicity, consider a perfect market where

Trading is costless. Information about borrowing and lending is

freely available to all participants. Everyone is a price taker: many competitive

traders; no one can move market prices.The result is that only one equilibrium interest rate will exist otherwise arbitrage opportunities would arise.

Under such assumptions, the one interest rate would apply to both borrowing and lending transactions.

5

Arbitrage Defined Arbitrage – the ability to earn a risk-free

profit from a zero net investment.

III. Two-period model

Consider a simple model where an individual lives for 2 periods, has an income endowment, and has preferences about when to consume.

Endowment (or given income) is $40,000 now and $60,000 next year

Two-period model: no market

Without the ability to borrow or lend using

financial markets, the individual is restricted to

just consuming his/her endowment as it is earned:

Intertemporal Consumption Opportunity Set

Assume a market for borrowing or lending exists and the interest

rate is 10%. This opens up a large set of consumption patterns

across the two periods.

IV. Real Investment Opportunities

The basic financial principle of investment decision making is this: An investment must be at least

as desirable as the opportunities available in the financial markets.

15

Real Investment Opportunities – Example 1

Consider an investment opportunity that costs $35,000 this year and provides a certain cash flow of $36,000 next year.

Is this a good opportunity?

V. Corporate Investment Decision‑Making Real investments may be done

through corporations where investors buy shares of the firm.

Shareholders will be united in their preference for the firm to undertake positive net present value projects, regardless of their personal intertemporal consumption preferences.

27

Corporate Investment Decision‑Making

Positive NPV projects shift the shareholder’s opportunity set out,

which is unambiguously good.

All shareholders agree on their preference for positive NPV

projects, whether they are borrowers or lenders.

Corporate Investment Decision‑Making

In reality, shareholders do not vote on every investment decision faced by a firm and the managers of firms need decision rules to follow.

All shareholders of a firm will be made better off if managers follow the NPV rule — undertake projects with NPV ≥ 0 and reject negative NPV projects.

29

VI. The Separation Theorem The separation theorem in financial markets says that

all investors will want to accept or reject the same investment projects by using the NPV rule, regardless of their personal preferences. Separation between consumption preferences and

real investment decisions Logistically, separating investment decision making

from the shareholders is a basic requirement for the efficient operation of the modern corporation. Managers don’t need to worry about individual

investor consumption preferences – just be concerned about maximizing their wealth.

30

VII. Summary and Conclusions Financial markets exist because people want to

adjust their consumption over time. They do this by borrowing or lending.

An investment should be rejected if a superior alternative exists in the financial markets.

If no superior alternative exists in the financial markets, an investment has a positive net present value and should be accepted.

NPV, IRR, PV and FV concepts are useful for working with cash flows through time and analyzing consumption and investment opportunities.
