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

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.

The Firm And Market Structures
The relationship between MR and price elasticity can be expressed as:
= −MR P[1 (1/E )]p
In a monopoly, MC = MR so:
− =P[1 (1/E )] MCp
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.

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.

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.

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
impact in future years.

annual depreciation expense underthe straight line method. Therefore,
the historical cost divided byannual depreciation expense
equals the estimated useful life.
Average age of asset
Annual depreciation expensetimes the number of years thatthe asset has been in use equals
accumulated depreciation.Therefore, accumulated
depreciation divided by annualdepreciation equals the average
age of the asset.

The book value of the asset dividedby annual depreciation expense
equals the number of years the assethas remaining in its useful life.

CT = max(0,ST − X)Value at expiration = –CT
Profit: Π = –CT − C0
Maximum profit = C0
Maximum loss = ∞Breakeven: ST* = X + C0
PT = max(0,X − ST)Value at expiration = –PT
Profit: Π = –PT − P0
Maximum profit = P0
Maximum loss = X − P0 Breakeven: ST* = X − P0
Where: C0, CT = price of the call option at time 0 and time TP0, PT = price of the put option at time 0 and time TX = exercise priceS0, ST = price of the underlying at time 0 and time TV0, VT = value of the position at time 0 and time TΠ = profit from the transaction: VT − V0
r = risk‐free rate
Covered Call
Value at expiration: VT = ST − max(0,ST − X)Profit: Π = VT − S0 + C0
Maximum profit = X − S0 + C0
Maximum loss = S0 − C0
Breakeven: ST* = S0 − C0
Protective Put
Value at expiration: VT = ST + max(0,X − ST)Profit: Π = VT − S0 − P0
Maximum profit = ∞Maximum loss = S0 + P0 − XBreakeven: ST* = S0 + P0
