Cost-Benefit Analysis
a financial manager needs to identify the costsand benefits of a financial decision in terms ofcash flows
costs as cash outflows
benefits as cash inflowshe needs the help of the other departments (suchas marketing, production, etc.) to quantify the
costs and benefitscost-benefit analysis helps him make the bestfinancial decision among a number of
alternatives

Cost-Benefit Analysis
when benefits exceed costs, it adds value to acompany and hence increases its shareholders’wealth

Role of Competitive Market Price
a competitive market is a market in which a goodcan be bought and sold at the same “market”price
in a competitive market, the market pricedetermines the value of a good (value inexchange) – which has nothing to do with thepersonal preferences of a consumer (value in use)or his assessment of its fair value
what do you do if the market price of an item
is $10 and its assessed fair value is $12?

Role of Market Price
in finance, we are more concerned with marketvalue of an item than its book value in thefinancial statements
e.g. a concert ticket with a face value of $100
can be sold at $250 in the marketthe book value is $100the market value is $250

Valuation Principle
“The value of a commodity or an asset to the firmor its investors is determined by the competitivemarket price . The benefits and costs of a decisionshould be evaluated using those market prices.
When the value of the benefits exceeds the valueof the costs, the decision will increase the marketvalue of the firm .”

Example: Valuation Principle
You are the operations manager of a firm. Due toa pre-existing contract, you have the discretion todecide whether to acquire 200 barrels of oil for$16,000. The current market price of oil is $90
per barrel. You believe that the value of oil wouldplummet to $70 over the next month. Should youor should you not buy the oil at the contract price
of $16,000?

Law of One Price and Arbitrage
law of one price (no-arbitrage condition) : incompetitive markets, securities with the samecash flows (and risk) should have the same pricearbitrage : the practice of simultaneous buying
and selling equivalent goods in two markets totake advantage of a price discrepancy (buy low,sell high)
arbitrage opportunity : any situation in which it ispossible to make a profit without taking any riskor making any investment
may take time

Law of One Price and Arbitrage
Given that there are no transaction costs, an itemis sold at $1,000 in one market and $1,200 inanother market, what do you do?

3.
buy it at $1,000
resell it at $1,200

Law of One Price and Arbitrage
if a lot of people rush to buy in the undervaluedmarket , the market price will rise
if a lot of people rush to sell in the overvalued
market , the market price will fall
sooner or later, the market prices will converge tothe same level and the law of one price holdsagain
does not hold

Effect of Inflation
inflation refers to a rise in general price levelit leads to a decline in the purchasing power ofmoney , i.e. the same amount of cash flows underinflation cannot buy the same quantity of goodsas the case without inflation
for example, you have $1,000if the price of an item is $100 each, you can
buy 10 unitsif the price of an item increases to $200each due to inflation, you can buy only 5
units

Effect of Inflation
inflation rate : the change in the average pricelevel of a basket of goods over a period, usuallymeasured through the consumer price index (CPI)
consumer price index (CPI) is a measure of theaverage price of a basket of consumer goods andservices purchased by households
inflation rate at time t = (CPI at time t – CPI at
time t-1)/CPI at time t-1

Example: Nominal and Real Interest
RatesIf the nominal interest rate on a financialinstrument is 5% and the expected inflation rateis 3%, what is the real interest rate?
real interest rate = (1+5%)/(1+3%) – 1 = 1.94%
real interest rate ≈ 5% - 3% = 2%

Deferred Consumption
given that inflation rate = 0%
if we receive cash flows now, we can consumeright away ( current consumption )if we will receive cash flows in a year’s time,
we can only consume in the future ( futureconsumption )
other things being equal, people prefer toconsume now to later (time preference )

Determining the Interest Rate
if we know about the present value, the futurevalue and the investment horizon, we candetermine the interest rate or the rate of returnon the investment
