TExES Economics Section

Scarcity

limits to satisfy wants

Choice

to select one think over another

Utility

point of greatest happiness

Opportunity Cost

the value of the option not chosen

Factors of Production (Resources)

-land (natural resources)-labor-physical capacity-entrepreneurial ability

Total Utility

sum of an individual's happiness -extent to which an individual's needs are met

Marginal Utility

the increase in happiness one gains from a product

Law of Diminishing Utility

states that the more unit of a product one has, the less one needs.

Marginal Benefit

additional benefit

Marginal Cost

additional cost per unit

Marginal Analysis

most helpful in company decision making regarding production

Production Possibilities Curve (Frontier)

-determines if an individual, company, or nation is producing at its most efficient level and what product will likely make the highest profit-shows opportunity costs, economic efficiency, economic growth, and scarcity

Economic Growth

the frontier expands over time

how to calculate opportunity cost

the slope of the PPC

Law of Increasing Costs

opportunity costs increase as the quantity produced increases

allocative efficiency

measurement of the benefit a product provides to society

absolute advantage

a company or nation can produce a good more efficiently than all its competitors

specialization

when an individual, company, or nation focuses on producing one thing-usually because it has a comparative advantage-leads to increased profits and lower prices for the consumer

traditional economy

pre-industrialized economy guided by tradition and often using bartering over currency

pure command economy

communist societies-the government (not the market) determines all aspects of production.

pure market economy

capitalism-governed by the laws of supply and demand with no outside interference

mixed economy

governed by the market and the government-people decide what is produced by what they are willing to buy-government regulates different aspects of the economy with regards to safety -most modern economies

Principle of Private Property

market favors private ownership of most economic resources.-leads to innovation and investment --> growth-allows for tradeex: FedEx or UPS are more efficient than USPS because they are privately owned vs gov owned

Freedom of Choice

in a market economy, all individuals are free to acquire, use, and sell resources w/o restriction or regulation

Self-Interest

motivates people in a market economy

Competition

leads to lower prices and higher quality to attract buyers

Law of Demand

as price increases, demand decreases-only affected by the relative (real) price

Demand Curve

shows how demand changes as price increases-measures quantity demanded

determinants of demand

-consumer income-price of a substitute good-price of a complementary good-consumer preferences-consumer expectations about future pricing-number of buyers in the market

Law of Supply

as the price increases, quantity increases to meet demand

Increasing Marginal Costs

as suppliers increase the amount they are supplying, the marginal costs of production increase as well

supply curve

show the relationship between the cost to produce a product and the quantity to be produced

determinants of supply

-cost of an input-technology and productivity-taxes and subsidies-producer expectations about future prices-prices of alternative goods that could be produced-number of similar companies in the industry

eslasticity

the measure of sensitivity to change

price elasticity of demand

measure the extent to which changes in price alter demandex: indicates the extent to which people would stop buying bread if the price of bread went upVERTICLE LINEEd= (%of change in quantity demanded)/(%change in price)

price inelastic

when the change in price is greater than the change in demand (Ed<1)

perfectly elastic

change in price that leads to unlimited demandHORIZONTAL LINE

unit elastic

any changes in price do not effect the demand of the productex: life-saving drug will always be in demand regardless of price

factors that impact elasticity

-proportion of income-number of good substitutes-time

Supply Curve of Labor

The number of hours a laborer is willing to work at a given wage rate-opportunity costs play a large role- increase in wages = increase in hours worked-demand for leisure increases as income increases (income effect)

stock

shares of a given company that has "gone public

money market funds

short term investments that are considered safe and solid -treasury bonds

Public Goods

products that an individual can consume without reducing their availability to other individuals-television, plumbing, etc.

Firm

any organization that uses factors of production to produce a good or service.

Sole Proprietorship

a business belonging to a single individual

Partnership

joint venture between two individuals/business entities

Corporation

group of individuals or businesses working together to share the business risk and profit-newest, 19th century

short term

a period in which at least one production input is fixed

long term

a period in which all production inputs are changeable

Long Run Equilibrium

price = average total cost-zero economic profit

Total Product of Labor

the total amount of product at each quantity of labor

Marginal Product of Labor

change in amount of a product resulting from a change in labor

Average Product of Labor

(total product)/(amount of labor that give average productivity of market labor)

Fixed Costs

do not change-rent, wages, insurance costs

Average Costs

(total cost to produce)/(# items produced)

Perfect Competition

-many small independent buyers and sellers-everybody produces the same product-there are no barriers to the entry/exit of old firms-all firms must accept the price where it is and produce it as much as they want at that price (because they cannot change it)*no one business that controls the entire marketplace because none are big enough

Monopoly

when one corporation or business controls an entire area or product of a given market-lack of close substitutes for the product-barriers to entry for new firms-market power*function best in a new market where competition is too expensive or not possible due to legal roadblocks

Oliogopoly

when few businesses control one market-interdependent as a result-have barriers

Price Floor

the lowest price established by the government-used to aid producers in unfair markets w lowered prices-if above market price , SURPLUS-if below, ineffective

Price Ceiling

highest price allowed by the government-if below market price, SHORTAGE

Anti-Trust Laws

used to promote a competitive market environment by protecting consumers from unfair business practices

Trust

control over the entire industrial process

Progressive Taxes

tac the income of the wealthy more than other groups-in free market: adjusted for income losses therefore tax % differs between income levels

Proportional Taxes

all taxpayers are taxed at the same rate or the same proportion their incomes

Regressive Taxes

affect everyone at the same rate without a sliding proportional scale-makes life more expensive for the lower classes

Circular Flow Model

shows where money goes in any given economy-follows money as it enters the marketplace to be spent by consumers and invested by businesses-reveals places in the economy where money is being wasted

Closed Economy

1. households provide factors and production to firms2. firms turn factors into goods and services3. firms pay households competitive compensation for the factors offered4. households use that income to buy goods and services created by the firms

GDP

Gross Domestic Product-total value of domestic production : market value of all final goods and services produced within a nation in one year*only counts what is produced within the country, products made abroad count for the country it is made in, not the country it is being made for

Consumer Price Index

the measure of the health of an economy based on consumer spending-measures the prices of goods and services as they change over timeCPI= 100x(spending Current year/spending Base year)

Inflation

the percent change from year to year in spending

economic growth

the outward movement (right) of the PPC over time-results from an increase in productivity

Determinants of Productivity

-physical capital (tools of production)-human capital (knowledge/skill of laborers)-natural resources-technology (knowledge/ability to efficiently produce goods, also computers and other tech)

Aggregate Supply

relationship between the total domestic output and average price level-sum of all microeconomic supply curves

Long Run Aggregate Supply Curve

represents the output level at full employment

Federal Reserve (Fed)

acts as a central bank of the US and ensures the safety of the American monetary system-created to stabilize the US money supply and to moderate interest rates

equilibrium interest rates

occur only when interest rates and monetary supply are equivalent-regulated by the Fed

monetary stabilization

efforts to keep prices, unemployment, and the money supply stable

Fiscal Policy

an approach to economic management in which the government is deeply involved in managing the economy

expansionary fiscal policy

government increases spending or decreases taxes in an effort to INCREASE AD curve-counteract recession

contractionary fiscal policy

government spending is reduced and taxes are increased in an effort to DECREASE AD curve-counteract inflation

Tarriff

tax on imports and exports

surplus

when revenue exceeds spending

deficit

the gap between what the government has spent and what it has earned

Comparative Advantage

whichever producer has a SMALLER opportunity cost in the item being produced

Absolute Advantage

the producer that can make more of the product using LESS resources than their competitors

monetary vs fiscal policy

monetary= interest rates, total supply of money in circulation (GDP)fiscal: taxing and spending actions of the government

Substitute Effect

when the price of a good rises OR income falls, consumers will replace more expensive items with cheaper substitute goods.

Income Effect

Consumer demand changes with changes in consumer income.EX: not buying a coffee that is $4 because it used to be $2 and is now going to cut out too much of their income.

Relationship between Price and the Demand of the good and complementary goods.

Inverse.Increase in Price = decrease in demand for good and complementary good
