Unemployment rate
The percentage of the total labor force that is unemployed at a given time
Microeconomics
Focuses on the behavior and purchasing decisions of individuals and firms
How is the market price determined?
Based on supply and demand
What a demand curve show graphically?
Inverse relationship between the price and quantity demanded - less products are demanded at higher prices
What shifts a demand curve?
Shifts when demand variables other than price change
What are variables that may cause a demand curve shift?
- changes in the price of other goods and services
- changes in consumer tastes
- changes in spendable income
- changes in wealth
- changes in the size of the market
What is the effect on demand if the price of other goods and services (substitutes) change?
Direct relationship. As goods that may be purchased instead go up in price the demand for the product goes up. As an example, if the price of pork increases the demand for beef may increase.
What is the effect on demand if the price of other goods and services (complements) change?
Inverse relationship. As the prices of complement goods go up, the demand for the product goes own. As an example, if the price of hamburger increases the demand for hamburger buns decreases.
What is the effect on demand if expectations of price increase?
Direct relationship. If the price of the good is expected to increase in the future, there will be an increase in demand.
What is the effect on demand if consumer income and wealth change?
Generally a direct relationship. As consumer income (wealth) goes up, the demand for many products (normal goods) goes up. However, there are certain goods that are inferior (e.g. bread, potatoes) and the demand for such goods actually goes up as consumer income(wealth) goes down.
What is the effect on demand if consumer tastes change?
Indeterminate relationship. The effect depends on whether the shift is towards or away from the product.
What is the effect on demand if the size of the market changes?
Direct relationship. As the size of the market increases, the demand for the product will increase.
What is the effect on demand if there is a group boycott?
Inverse relationship. If a group of consumers boycott a product, demand will be decreased.
Price elasticity of demand?
Measures the sensitivity of demand to a change in price?
Price elasticity demand equation
E = % change in QD/% change in price
What is the arc method in regards to price elasticity demand?
This makes results the same regardless of whether there is an increase or decrease in price
E = Change in QD/Avg Q / Change in price/Avg price
Interpretation of the demand elasticity coefficient?
ED > 1 = demand is elastic (sensitive to price changes)
ED = 1 = demand is unitary (not sensitive or insensitive to price changes)
ED
What is the relationship between price elasticity and total revenue?
Total revenue from the sale of a good is equal to the price times the quantity
What happens when there is a price increase and the demand is elastic E > 1?
Total revenue decreases
What happens when there is a price increase and the demand is inelastic E
Total revenue increases
What happens when there is a price increase and the demand is unitary E = 1?
Total revenue does not change
What happens when there is a price decrease and the demand is elastic E > 1?
Total revenue increases
What happens when there is a price decrease and the demand is inelastic E
Total revenue decreases
What happens when there is a price decrease and the demand is unitary E = 1?
Total revenue does not change
Why is price elasticity an important concept?
Reveals whether the firm is likely to be able to [pass on cost increases to its customers. E.g. when demand is inelastic the firm can increase its price with less of a negative impact.
Income elasticity of demand
Measures the change in the quantity demanded of a product given a change in income
Equation of income elasticity of demand?
E = % change in QD / % change in income
What does income elasticity of demand describe?
Nature of the product (normal v. inferior goods)
Normal goods
Demand for normal products increases as consumer income increases (EI is positive)
Inferior goods
Demand for inferior products decreases as consumer income decreases (EI is negative)
Cross-elasticity of demand
Measures the change in demand for a good when the price of a related or competing product is changed
Coefficient (equation) for cross-elasticity of demand
Exy = % change in the QD of product x / % change in the price of product y
What does a positive cross-elasticity coefficient mean?
The products are substitutes
What does a negative cross-elasticity coefficient mean?
The products are complements
What does a zero cross-elasticity coefficient mean?
The products are unrelated
Substitution effect
As the price of a good falls, consumers will use it to replace similar goods
Income effect
As the price of a good falls, consumers can purchase more with a given level of income
Law of diminishing marginal utility
The more goods an individual consumes the more total utility the individual receives. However, the marginal (additional) utility from consuming each additional unit decreases.
When does a consumer maximize utility?
When marginal utility of the last dollar spent on each commodity is the same
Utility maximization mathematically
Marginal Utility of A / Price of A = Marginal Utility of B / Price of B = Marginal Utility of C / Price of C
Indifference curves
Illustrate utilities
What is the optimal level of consumption?
Individual’s budget constraint line intersects the highest possible utility curve
What is one of the factors that consumption depends on?
Personal disposable income - amount of income consumers have after receiving transfer payments from the government (welfare) and paying their taxes
Consumption function
Relationship between changes in personal disposable income and consumption
What is the equation for consumption function?
C = c0 + c1Yd
- C = Consumption for a period
- Yd = Disposable income for the period
- c0 = constant
- c1 = slope of the consumption function
Why is the slope, c1, important in the consumption factor?
Measures the consumer’s marginal propensity to consume (MPC) . Describes how much of each additional dollar in personal disposable income that the consumer will spend
Marginal propensity to save (MPS)
Percentage of additional income that is saved
MPS & MPC equation
MPS + MPC = 1
What are other nonincome factors that may affect consumption?
- Expectations about future prices of goods
- Quantity of consumer liquid assets
- Amount of consumer debt
- Stock of consumer durable goods
- Attitudes about saving money
- Interest rates
What does a supply curve show?
The amount of a product that would be supplied at various prices. Shows a direct relationship between price and quantity sold. The higher the price the more products that would be supplied.
How does a change in price affect the supply curve?
Causes a shift along the existing supply curve (does not shift the curve out)
What causes a supply curve shift?
When supply variables other than price change
- Changes in number or size of producers
- Changes in various production costs (wages, rents, raw materials)
- Technological advances
- Government actions
How does the number of producers affect the supply of the product?
Direct relationship. Generally an increase in the number of producers will cause an increase in the amount of goods supplied at a given price.
How does a change in production costs or technological advances affect the supply of the product?
Inverse relationship. As production costs go up, fewer products will be supplied at a given price. If costs go down, more products will be produced
How does government subsidies affect the supply of the product?
Direct relationship. Subsidies in effect reduce the production cost of goods and therefore increase the goods supplied at a given price
How do government price controls affect the supply of the product?
Price controls would tend to limit the amount of goods supplied by holding the price artificially low.
How do prices of other goods affect the supply of the product?
Inverse relationship. If the products can be produced with greater returns, producers will produce those goods.
How do price expectations affect the supply of the product?
Direct relationship. If it is expected that prices will be higher for the good in the future, production of the good will increase.
What is the elasticity of supply?
Measures the percentage change in the quantity supplied of a product resulting from a change in the product price.
Elasticity of supply equation
Es = $ change in quantity supplied / percentage change in price
- Es > 1 = elastic (% increase in price will create a larger % increase in supply)
- Es
Market equilibrium
Determined by demand and supply. It is the price at which all the goods offered for sale will be sold (QD = QS)
Examples of government interventions
Taxes, subsidies, and rationing
E.g. subsidy paid to farmers will reduce the cost of producing a particular product and cause equilibrium price to be lower than it would be without the subsidy
E.g. import taxes would increase the cost of an imported product causing equilibrium price to be higher
Price ceiling
Specified max price that may be charged for a good; if max price is set below equilibrium price, this causes a shortage
Price floor
Specified price that may be charged for a good; if price floor is set for a good above equilibrium price, it will cause overproduction and surpluses will develop
What does government intervention result int?
Inefficient allocation of resources
Externalities
Describe damage to common areas that is caused by the production of certain goods
E.g. pollution
What happens when there is an increase in demand with no change in supply?
Equilibrium price will increase and quantity purchased will increase
What happens when there is a decrease in demand with no change in supply?
Equilibrium price will decrease and quantity purchased will decrease
What happens when there is an increase in supply with no change in demand?
Equilibrium price will decrease and quantity purchased will increase
What happens when there is a decrease in supply with no change in demand
Equilibrium price will increase and quantity purchased will decrease
What happens when both demand and supply increase?
Quantity purchased will increase and new equilibrium price will be indeterminate
What happens when both demand and supply decrease?
Quantity purchased will decrease and new equilibrium price will be indeterminate
What happens when demand increases and supply decreases?
Equilibrium price will increase and quantity purchased is indeterminate
What happens when demand decreases and supply increases?
Equilibrium price will decrease and quantity purchased is indeterminate
In the short-run, what do firms have?
Variable and fixed costs
Total fixed costs
Costs that are committed and will not change with different levels of production
E.g. Rent paid on a long-term lease for a factory
Variable costs
Costs of variable inputs, such as raw materials, variable labor costs, and variable overhead.
These costs are directly related to the level of production for the period
Average fixed cost (AFC)
Fixed cost per unit of production. It goes down consistently as more units are produced.
Average variable cost (AVC)
Total variable costs divided by number of units produced; initially stays constant until the inefficiencies of producing in a fixed-size facility cause variable costs to begin to rise
Marginal cost (MC)
The added cost of producing one extra unit. It initially decreases but then begins to increase due to inefficiencies
Average total cost (ATC)
Total costs divided by the number of units produced. Its behavior depends on the makeup of fixed and variable costs
Long-run total costs
All inputs are variable because additional plant capacity can be built
If in the long run a firm increases all production factors by a given proportion; three possible outcomes
- Constant returns to scale: output increases in same proportion
- Increasing returns to scale: output increases by a greater proportion
- Decreasing returns to scale: output decreases by a smaller proportion
Normal profit
Amount of profit necessary to compensate the owners for their capital and/or managerial skills; just enough profit to keep the firm in business in the long-run
Economic profit
The amount of profit in excess of normal profit; cannot be experienced in a perfectly competitive market in the long-run
How does management make production decisions?
Based on relationship between marginal revenue and marginal cost.
A good should be produced and sold as long as the marginal cost of producing the good is less than or equal to the marginal revenue from the sale of the good
Marginal product
Additional output obtained from employing one additional unit of a resource
Marginal revenue product
Change in total revenue from employing one additional unit of a resource
Marginal revenue per-unit
Marginal revenue product / increase in products produced by employing one additional unit of resource (marginal product)
How is the cost of production in the long-run minimized?
When the marginal product (MP) per dollar of every input is the same
MP of input A/Price input A = MP input B /Price input B
Macroeconomics
- Looks at the economy as a whole
- Focuses on measures of economic output, employment, inflation, and trade surpluses or deficits
What are the three major segments of the economy?
Consumers, business, and government
Nominal gross domestic product (GDP)
The price of all goods and services produced by a domestic economy
Real GDP
The price of all goods and services produced by the economy at price level adjusted (constant) prices. Price level adjustment eliminates the effect of inflation on the measure
Potential GDP
The maximum amount of production that could take place in an economy without putting pressure on the general level of prices.
What is the difference between potential GDP and real GDP?
This is the GDP gap.
- Positive GDP gap indicates there are unemployed resources in the economy and we would expect unemployment
- Negative GDP gap indicates that the economy is running above normal capacity and prices should begin to rise
Net domestic product (NDP)
GDP minus depreciation
Gross National Product (GNP)
The price of all goods and services produced by labor and property supplied by the nation’s residents
Income approach
One way to calculate GDP
Adds up all incomes earned in the production of final goods and services, such as wages, interest, rents, dividends
Expediture approach
One way to calculate GDP
Adds up all expenditures to purchase final goods and services by households, businesses, and the government. Specifically, it includes personal consumption expeditures, gross private investment in capital goods. Also includes the country’s net exports.
Income side of GDP
Compensation to employees Corporate profits Net interest Proprietor's Income Rental income of persons =National income Plus: indirect taxes Minus: other, including statutory discrepancy =Net national product Plus: consumption of fixed capital =Gross national product Plus: payments of factor income to other countries Minus: receipts of labor income from other countries =Gross domestic product
Product side of GDP
Personal consumption expeditures Gross private domestic fixed investment Government purchases Net exports (negative) Changes in business inventories =Gross domestic product
Aggregate demand curve
Depicts the demand of consumers, businesses, and government as well as foreign purchasers for the goods and services of the economy at different price levels
-Inversely related to price level
Interest rate effect
As price levels increase (inflation increases) nominal interest rates increase causing a decrease in interest sensitive spending.
Interest sensitive spending includes spending for items such as houses, automobiles, and appliances
