Topics in Demand and Supply Analysis

The demand function captures the effect of all these factors on demand for a good.

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 own‐price elasticity of demand is calculated as:

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

Normal profit = Accounting profit − Economic profit

Economic profit = Accounting profit − Total implicit opportunity costs

Economic profit = Total revenue − (Explicit costs + Implicit costs)

Normal Profit

Total, Average and Marginal Revenue

Table: Summary of Revenue Terms2

Revenue Calculation

Total revenue (TR) Price times quantity (P × Q), or the sum of individual units sold times their respective prices; Σ(Pi × Qi)

Average revenue (AR) Total revenue divided by quantity; (TR / Q)

Marginal revenue (MR) Change in total revenue divided by change in quantity; (ΔTR / ΔQ)

Total, Average, Marginal, Fixed and Variable Costs

Table: Summary of Cost Terms3

Costs Calculation

Total fixed cost (TFC) Sum of all fixed expenses; here defined to include all opportunity costs

Total variable cost (TVC) Sum of all variable expenses, or per unit variable cost times quantity; (per unit VC × Q)

Total costs (TC) Total fixed cost plus total variable cost; (TFC + TVC)

Average fixed cost (AFC) Total fixed cost divided by quantity; (TFC / Q)

Average variable cost (AVC) Total variable cost divided by quantity; (TVC / Q)

Average total cost (ATC) Total cost divided by quantity; (TC / Q) or (AFC + AVC)

Marginal cost (MC) Change in total cost divided by change in quantity; (ΔTC / ΔQ)

Marginal revenue product (MRP) of labor is calculated as:

MRP of labor = Change in total revenue / Change in quantity of labor

MRP = Marginal product * Product price

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.

A profit‐maximizing firm will hire more labor until:

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.

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 servicesI = 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 servicesX = ExportsM = Imports

Expenditure Approach

Under the expenditure approach, GDP at market prices may be calculated as:

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 allowanceStatistical 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.

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.

Equilibrium in the money market requires that money supply and money demand be equal.

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.

Financial Statement Effects of Capitalizing versus Expensing

Effect on Financial StatementsInitially when the cost is capitalized

• Noncurrent assets increase.• Cash flow from investing activities decreases.

In future periods when the asset is depreciated or amortized

• Noncurrent assets decrease.• Net income decreases.• Retained earnings decrease.• Equity decreases.

When the cost is expensed • Net income decreases by the entire after‐tax amount of the cost.

• No related asset is recorded on the balance sheet and therefore, no depreciation or amortization expense is charged in future periods.

• Operating cash flow decreases.• Expensed costs have no financial statement

the historical cost divided byannual depreciation expense

equals the estimated useful life.

Yield Spread:

Yield spread Liquidity premium Credit spread= +

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:

Return impact (MDur Spread) (1/2 Convexity Spread )2≈ − × ∆ + × × ∆
