Demand and Supply Analysis: Introduction
The demand function captures the effect of all these factors on demand for a good.
Demand function: QDx = f(Px, I, Py , …) … (Equation 1)
Equation 1 is read as “the quantity demanded of Good X (QDX) depends on the price of
Good X (PX), consumers’ incomes (I) and the price of Good Y (PY), etc.”
The supply function can be expressed as:
Supply function: QSx = f(Px,W, …) … (Equation 5)
The own‐price elasticity of demand is calculated as:
EDPx =
%∆QDx
… (Equation 16)
%∆Px
If we express the percentage change in X as the change in X divided by the value of X,
Equation 16 can be expanded to the following form:

Accounting Profit
Accounting profit (loss) = Total revenue − Total accounting costs.
Economic Profit
Economic profit (also known as abnormal profit or supernormal profit) is calculated as:
Economic profit = Total revenue − Total economic costs
Economic profit = Total revenue − (Explicit costs + Implicit costs)
Economic profit = Accounting profit − Total implicit opportunity costs
Normal Profit
Normal profit = Accounting profit - Economic profit

Marginal revenue product (MRP) of labor is calculated as:
MRP of labor = Change in total revenue / Change in quantity of labor
For a firm in perfect competition, MRP of labor equals the MP of the last unit of labor
times the price of the output unit.
MRP = Marginal product * Product price

P[1 − (1/E p )] = MC
N‐firm concentration ratio: Simply computes the aggregate market share of the N
largest firms in the industry. The ratio will equal 0 for perfect competition and 100 for a
monopoly.
Herfindahl‐Hirschman Index (HHI): Adds up the squares of the market shares of each of
the largest N companies in the market. The HHI equals 1 for a monopoly. If there are M
firms in the industry with equal market shares, the HHI will equal 1/M.
Aggregate Output, Price, And Economic Growth
Nominal GDP refers to the value of goods and services included in GDP measured at
current prices.
Nominal GDP = Quantity produced in Year t × Prices in Year t
Real GDP refers to the value of goods and services included in GDP measured at
base‐year prices.
Real GDP = Quantity produced in Year t × Base-year prices

Economics
The Components of GDP
Based on the expenditure approach, GDP may be calculated as:
GDP = C + I + G + (X − M)
C = Consumer spending on final goods and services
I = Gross private domestic investment, which includes business investment in capital goods
(e.g. plant and equipment) and changes in inventory (inventory investment)
G = Government spending on final goods and services
X = Exports
M = Imports
Expenditure Approach
Under the expenditure approach, GDP at market prices may be calculated as:
GDP = Consumer spending on goods and services
+ Business gross fixed investment
+ Change in inventories
+ Government spending on goods and services
+ Government gross fixed investment
+ Exports − Imports
+ Statistical discrepancy
This equation is just
a breakdown of the
expression for GDP
we stated in the
previous LOS, i.e.
GDP = C + I + G +
(X − M).
Income Approach
Under the income approach, GDP at market prices may be calculated as:
GDP = National income + Capital consumption allowance
+ Statistical discrepancy
… (Equation 1)
National income equals the sum of incomes received by all factors of production used to
generate final output. It includes:
•
•
•
•
•
Employee compensation
Corporate and government enterprise profits before taxes, which includes:
○○ Dividends paid to households
○○ Corporate profits retained by businesses
○○ Corporate taxes paid to the government
Interest income
Rent and unincorporated business net income (proprietor’s income): Amounts
earned by unincorporated proprietors and farm operators, who run their own
businesses.
Indirect business taxes less subsidies: This amount reflects taxes and subsidies that
are included in the final price of a good or service, and therefore represents the
portion of national income that is directly paid to the government.

Economics
The capital consumption allowance (CCA) accounts for the wear and tear or depreciation
that occurs in capital stock during the production process. It represents the amount that
must be reinvested by the company in the business to maintain current productivity levels.
You should think of profits + CCA as the amount earned by capital.
Personal income = National income
− Indirect business taxes
− Corporate income taxes
− Undistributed corporate profits
+ Transfer payments
… (Equation 2)
Personal disposable income = Personal income − Personal taxes … (Equation 3)
Personal disposable income = Household consumption + Household saving
… (Equation 4)
Household saving = Personal disposable income
− Consumption expenditures
− Interest paid by consumers to businesses
− Personal transfer payments to foreigners … (Equation 5)
Business sector saving = Undistributed corporate profits
+ Capital consumption allowance … (Equation 6)
GDP = Household consumption + Total private sector saving + Net taxes
The equality of expenditure and income
S = I + (G − T) + ( X − M) … (Equation 7)
The IS Curve (Relationship between Income and the Real Interest Rate)
Disposable income = GDP − Business saving − Net taxes
S − I = (G − T) + ( X − M) … (Equation 7)

Economics
The LM Curve
Quantity theory of money: MV = PY
The quantity theory equation can also be written as:
M/P and MD/P = kY
where:
k = I/V
M = Nominal money supply
MD = Nominal money demand
MD/P is referred to as real money demand and M/P is real money supply.
Equilibrium in the money market requires that money supply and money demand be equal.
Money market equilibrium: M/P = RMD
Solow (neoclassical) growth model
Y = AF(L,K)
where:
Y = Aggregate output
L = Quantity of labor
K = Quantity of capital
A = Technological knowledge or total factor productivity (TFP)
Growth accounting equation
Growth in potential GDP = Growth in technology + WL (Growth in labor)
+ WK (Growth in capital)
Growth in per capital potential GDP = Growth in technology
+ WK (Growth in capital-labor ratio)
Measures of Sustainable Growth
Labor productivity = Real GDP/Aggregate hours
Potential GDP = Aggregate hours × Labor productivity
This equation can be expressed in terms of growth rates as:
Potential GDP growth rate = Long‐term growth rate of labor force + Long‐term labor
productivity growth rate

Understanding Business Cycles
Unit labor cost (ULC) is calculated as:
ULC = W/O
where:
O = Output per hour per worker
W = Total labor compensation per hour per worker
Monetary And Fiscal Policy
Required reserve ratio = Required reserves / Total deposits
Money multiplier = 1/ (Reserve requirement)
The Fischer effect states that the nominal interest rate (RN) reflects the real interest rate
(RR) and the expected rate of inflation (IIe).
R N = R R + Πe
The Fiscal Multiplier
Ignoring taxes, the multiplier can also be calculated as:
○○ 1/(1-MPC) = 1/(1-0.9) = 10
Assuming taxes, the multiplier can also be calculated as:
1
[1 - MPC(1-t)]
International Trade And Capital Flows
Balance of Payment Components
A country’s balance of payments is composed of three main accounts:
• The current account balance largely reflects trade in goods and services.
• The capital account balance mainly consists of capital transfers and net sales of
non‐produced, non‐financial assets.
• The financial account measures net capital flows based on sales and purchases of
domestic and foreign financial assets.

Economics
Currency Exchange Rates
The real exchange rate may be calculated as:
Real exchange rate DC/FC = SDC/FC × (PFC /PDC )
where:
SDC/FC = Nominal spot exchange rate
PFC = Foreign price level quoted in terms of the foreign currency
PDC = Domestic price level quoted in terms of the domestic currency
The forward rate may be calculated as:
FDC/FC =
(1 + rDC )
(1 + rDC )
1
×
or FDC/FC = SDC/FC ×
(1 + rFC )
SFC/DC (1 + rFC )
This version of the
formula is perhaps
easiest to remember
because it contains
the DC term in
numerator for all
three components:
FDC/FC, SDC/FC and
(1 + rDC)
Forward rates are sometimes interpreted as expected future spot rates.
Ft = St +1
(St +1 )
(r − r )
− 1 = ∆%S(DC/FC)t +1 = DC FC
S
(1 + rFC )
Exchange Rates and the Trade Balance
The Elasticities Approach
Marshall-Lerner condition: ω x ε x + ω M (ε M − 1) > 0
where:
ωx = Share of exports in total trade
ωM = Share of imports in total trade
εx = Price elasticity of demand for exports
εM = Price elasticity of demand for imports

Modified duration has a very important application in risk management. It can be used to

If Macaulay duration is not already known, annual modified duration can be estimated
using the following formula:

For small, instantaneous changes in the yield spread, the return impact (i.e. the percentage
change in price, including accrued interest) can be estimated using the following formula:
Return impact ≈ − Modified duration × ∆Spread
For larger changes in the yield spread, we must also incorporate the (positive) impact of
convexity into our estimate of the return impact:

Fundamental value of an asset (S0) that incurs costs (θ) and generates benefits (γ):
 E(ST ) 
S0 = 
T −θ+ γ
 (1 + r + λ) 
Arbitrage and Replication:
Asset + Derivative = Risk-free asset
Asset − Risk-free asset = − Derivative
Derivative − Risk-free asset = − Asset
Forward Contract Payoffs:
Long position
Short position
ST > F(0,T)
ST – F(0,T)
(Positive payoff)
ST < F(0,T)
ST – F(0,T)
(Negative payoff)
–[ST – F(0,T)]
(Negative payoff)
–[ST – F(0,T)]
(Positive payoff)
Forward price:
F(0,T) = S0 (1 + r)T
F(0,T) = (S0 − γ + θ)(1 + r)T or F(0,T) = S0 (1 + r)T − ( γ − θ)(1 + r)T
*Note
that benefits (γ) and costs (θ) are expressed in terms of present value.
Value of a forward contract:
Vt (0,T) = St − [F(0,T) / (1 + r)T− t ]
Vt (0,T) = St − ( γ − θ)(1 + r) t − [F(0,T) / (1 + r)T− t ]
