Scarcity
the discrepancy between limited resources and unlimited desires.
Basic Economic Questions
What? How? and For Whom?
Basic Economic Question 1. What?
What goods and services to produce? demand is determiner, price is indicator.
Basic Economic Question...2. How?
How best to produce the goods and services determined by 'What?', Determine which of 4 basic resource groups you will use. Labor, Capital, Land, Entrepreneurial and how much of each.
Basic Economic Question...3. For Whom?
Distribution. capatilist systems may use marketing - to those who can afford to buy and some subsidies.,
4 Economic Systems
1. Traditional (barter), 2. Capitalist, 3. Socialist, 4. Mixed.
Traditional Economic System
The Barter System. trading one product for another. Works best in small economies-in large economies requires much trading to get goods one actually wants or needs.
Capitalist Economic System
Market Economy or Free Enterprise or Laissez-faire ("let it be"). Private business free to operate and compete with very little government regulation. Value of goods and services determined by competitive market-requires many buyers and sellers to avoid monopolies.
Market Economy
Capitalist System
Free Enterprise
Capitalist System
Laissez-faire
"let it be" in french. Describes Capitalist System of little to no government involvement.
The Invisible Hand
Used in Wealth of Nations by Adam Smith to describe why, though the individual is selfish, his actions can also benefit the whole community.
Adam Smith
Scottish philosopher wrote The Wealth of Nations. Considered the father of economics.
The Wealth of Nations
written by Adam Smith.
Conditions required for the invisible hand to work
1. stable property rights, 2. economic freedom to use property or consume whatever people wish.
Property Rights
1 of 2 conditions necessary for the invisible hand of the free market/capitalist system to work. Requires that people have a clear, stable, continuing right to personal property.
Economic freedom is required for the successful _______ effect.
1 of 2 conditions required for the 'invisible hand' of the free market/capitalist system to work. People must be able to own and or consumer what they wish.
Competition (define for free market)
in a free market it is a process of discovering new and better ways to use resources.
Social Cooperation and the Market
free markets require the participation of the consumer to determine the real value of goods and services. The consumers require the cooperation of the producers to respond to demand/price and provide those products and services consumers value.
The Socialist System
1 of 4 basic economic systems. aka centerally-planned system or command economy. private enterprise abolished, government owned property and economic planners decide what, how and for whom, prices and wages set by planners. System is difficult to manage because no venue for reliable informaiton for planners to act on.
Mixed Economy
1 of 4 basic economic systems. government plays a role along side the private sector.
One way to determine relative economic freedom in a country
determine how much of the GDP is made up of government spending. The more government spending, the less consumer input the market receives.
GDP
Gross Domestic Product
Opportunity Cost
the difference in cost/resources used/time between action chosen and the best foregone alternative 
 
(produce another product, be in one place rather than another)
Opportunity Cost formula
opportunity costs = losses/gains or opportunity costs = best option foregone-choice made.
Production Possibilities Curve (PPC)
reflects the maximum number of goods that a society can produce at any given time, with the given resources and know-how (technology). Note: reflects Technical Efficiency, not Economic Efficiency. Does not take into account what society wants, just the most efficient use of resources.
3 assumptions when studying Production Possibility Curve
a) resources (land, labor force, capital and entrepreneurship skills)are fixed, but each of the resources can be used to produce different types of goods and services. b)all the resources are fully and efficiently used. c)Technology (know-how) which includes the quality of the capital (machinery) and the education of the labor force, stays as it is. (know-how is assumed to remain constant for the given period.
Shape of the Production Possibilities Curve
concave as a result of the increasing opportunity costs. Also called a frontier line or boundary.
Unattainable Area "U"
the area beyond the Production Possibility curve/boundry/frontier that indicates an unattainable outcome due to insufficient resources or know-how.
Inefficient Region "I"
The area within the Production Possibility curve which indicates production that does not efficiently utilize all resources and know-how.
Efficient Use of Resources
when an economy is producing at its maximum. Indicated by existing on the Production Possibility Curve/boundry/frontier.
Opportunity Cost on a Straight Line
Indicates that the opportunity cost is constant because there is a one for one exchange for each available option.
4 Factors that shift the Production Possibility Curve to the right
Shifting PPC to the right indicates an increase in production ability. This can be due to: a) technology. b) increase in resources. c) increase in quality and/or quantity of population. d) capital formation (foregoing immediate consumption to devote resources to creation of capital goods that will increase productivity).
Factors that shift the Production Possibility Curve to the left. (4)
Shift of the PPC to the left indicates a decrease in production ability. a) depletion of natural resources. b) population quality or quantity reduction. c) natural disasters. d) war.
Partial shift in Production Possibility Curve
reflects an increase or decrease in ability to produce in less than all sectors represented by the PPC.
Rule of 72
the formula used to indicate the length of time necessary to double principal based on interest rate earned. divide 72 by rate to get number of years to double principal. Years to Double Pricipal=72/rate. 100 will double at 3% interest in _____ years. (24 years)
Technical Efficiency
using the least resources possible to produce a given level of output
Economic Efficiency
applying resources to produce goods or services that society's members value most highly.
What is the difference between Technical and Economic Efficiency
Technical Efficiency reflects the most effienct use of the 4 key limited resources, but doesn't reflect if the model efficiently meets the needs/desires of society (economic efficiency).
Pareto Efficiency
A change in resource allocation between two or more producers that makes those involved in one activity better off without making those involved in another activity worse off. This doesn't mean that everyone has to be better off, only that gains should exceed losses.

3 basic Economic Questions
What, How and For Whom?
increase in demand will ________ equilibrium price and ________ equilibrium quantity.
Increase in both cases.
increase in demand can be due to: 5 factors
1. price of other goods. 2. increase in population. 3. changes in taste. 4. increase in income. 5. changes in expectations.
Quantity demanded
a change from one point to another along one demand curve. Either decreases or increases Quantity demanded. Can only be effected by change in price per unit.
Increase in price per unit will decrease __________
Quantity demanded
Increase in quantity demanded is caused by
decrease in price per unit
decrease in quantity demanded
reflects increase in price per unit
Decrease in price per unit will cause
increase in quantity demanded.
price per unit and quantity demanded have a _______ relationship.
indirect, inverse or negative relationship.
slope = (formula)
change in y/change in x
The Law of Demand
assuming ceteris paribus (all things constant except price) more goods will be purchased at lower prices or fewer goods will be purchased at higher prices. When prices goes down, we buy more; when price goes up we buy less.
Factors that remain constant during price change (5)
size of the population 2)consumer's incomes 3) tastes 4) epectations 5) price of other goods on the market.
Demand Schedule (define)
list of different quantities of a product or service that a person is willing and able to buy at different prices over a specified period of time, assuming ceteris paribus (all other things constant).
substitute goods (define)
goods that have similar use and give nearly similar satisfaction
Normal Good (define)
a product for which demand increases with an increase in population income.
Inferior Good (define)
a product for which demand increases with a decrease in population income. (99cents only stores)
Change in quantity demanded (define)
a move along the Demand curve caused by price of the product.
Change in Demand Curve (shift right or left) demand
Anything that effects a shift in the entire demand curve caused by anything that effects your willingness to buy other than price of the product.
Investment (define)
the accumulation of capital
The Law of Diminishing Marginal Utility
The more of a product that is consumed, the less satisfication (utility) the consumer will derive. Therefore, in order to sell more of a product, the price of the good has to progressively decrease as utility (satisfaction) decreases.
Demand Schedule
list of the different quantities of a product or service that a person is willing and bale to buy at different prices over a specified period of time while keeping all other factors constant. ceteris parubis
Three reasons why Demand Curve slopes downward
1) substituttion effect. 2) Real income effect 3) The Law of Diminishing Marginal Utility.
Substitution Effect
when the price of one product goes up people will buy another product or service that is similar in use and that gives nearly the same satisfaction as the first product.
Real Income Effect
when prices drop, consumers enjoy a savings which translates to increased buying power or income.
How do you calculate a market demand curve?
add together all quantities demanded at each price (horizontal summation). Add tables across (total derived is point on graph at that price).
Price Theory
the study of Supply and Demand.
Quantity supplied > Quantity demanded
Surplus
Quantity demanded > Quantity supplied
shortages
Quantity demanded = Quantity supplied
Equilibrium
Buyer's market (define)
existance of a surplus
Seller's market (define)
existence of a shortage
Equilibrium Price
The price at which the willingness to buy and the willingness to supply meet and the market is cleared or all buyers get a product and all products are sold.
Change in quantity demanded
effected by price only
Change in demand
effect by anything but price.
Factors that determine demand (5)
Income (normal goods income has direct relationship, inferior goods and income have an inverse relationship), taste and preference, price of other goods (substitute goods and an inverse relationship with each other, complementary goods have a direct relationship with each other), consumer expectations and population.
difference between changes in quantity supplies and Supply.
Quantity supplied effected by price only, Supply effected by all other things.
Which way does the Demand curve slope
downward
which way does the supply curve slope
upward
Factors that determine supply (8)
Technology. 2)price of inputs. 3) price of other goods. 4. Size and number of firms. 5) producer expectations. 6. Taxes (per unit). 7. Subsidies (per unit). 8. Government law.
Technology as it determines Supply
increases in technology allow the more effiecient use of other resources at all price levels, thereby shifting the supply curve to the right. The inverse can be true with the loss of technology.
Price of inputs as it determines Supply
aka factors of production. Inputs or factors of production are the resources needed to produce, therefore the increase or decrease in price of a given input will directly determine the price of production at all price levels or will shift the Supply curve right or left.
Price of other goods as they determine Supply
substitutes of production are goods that can be produced with the same resources (inputs). If the price of one good increases more inputs will be devoted to creating that good, thereby reducing the amount of resources devoted to product of the substitute good. complements in production: goods for which increase in production of one leads to increase in production of another. If cereal become more popular, the cost will go up, price of corn will go up, cost of ethanol will go up because corn costs more.
Size and number of firms as it pertains to determining Supply
if only one firm, then a monopoly they will limit supply in order to raise prices, many firms they will increase supply.
Producer's expectations as it determines Supply.
If producers expect high demand they will produce more, if they expect low demand they will produce less.
Taxes (per unit) as they determine Supply.
An increase in cost (taxes) will shift the supply curve to the left, reducing supply. opposite is also true.
Subsidies (per unit) as they determine Supply.
subsidies reduce the cost per unit of a good, thereby encouraging producers to supply more.
Gpverm,emt ;aws as tjeu determine supply.
a) licenses limits the number of producers thereby decreasing Supply (see # of firms). b) Import quotas aslo limit the number of producers - see a
Substitutes in Production change the equiilibrium qunatity in ______ direction
the opposite.
Complements in Production change the Equilibrium Price _______ direction.
the same.
Laws of Supply and Demand 4 basic situtations:
1) Increase in Demand. 2) Decrease in Demand. 3) Increase in Supply. 4) Decrease in Supply.
Increase in Demand as it applies to Supply and Demand
Increase in Demand is always accompanied by an increase in the equilibrium price and equilibrium quantity.
Decrease in Demand as it effects Supply and Demand
Any decrease in demand is always accompaniedby a decrease in equilibrium price and equilibrium quantity.
Increase in Supply as it effects Supply and Demand
Increase in Supply = decrease in equilibrium price and increase in the equilibrium quantity.
Decrease in Supply as it effects Supply and Demand:
decrease in supply = increase in equilibrium price and decrease in equilibrium quantity.
Increase in Supply and Demand
when consumers wants something, but other increases (say in technology) make it cheaper to produce: even though demand should set a higher equilibrium price, the lower cost to produce due to other factors wants to set a lower equilibrium price. Three possibilities: 1) if Supply and Demand increase equally, equilibrium price stays the same. 2) if demand increases more than supply then the equilibrium price will increase. 3) if supply increases more than demand then the equilibrium price will decrease. Only sure thing is that equilibrium quantity will increase. Equilibrium price is indeterminate.
What will Equilibrium Price do when Supply and Demand both increase or decrease similtaneously?
It is indeterminate. it can stay the same, increase or decrease depending on the amount of decrease or increase of each of supply and demand.
What will happen to equilibrium quantity when Supply and Demand both increase.
It will increase.
What is the only outcome we can be sure of with increasing Supply and Demand
that Equilibrium Quantity will increase. Equilibrium Price is indeterminate without specific info on the increase of Supply and Demand.
Increase in Demand, Decrease in Supply
Equilibrium Price will increase, but Equilibrium Quantity will be indeterminate.
Decrease in Supply and Demand
Equilibrium quantity will decrease, but Equilibrium Price is indeterminate.
Decrease in Demand, increase in Supply
Equilibrium Price will decrease, but Equilibrium Quantity will be indeterminate.
Price ceilings, - maximum price
(such as rent control): price is deliberately set below the equilibrium. Result in shortages.
Black Market
when price of product is legally set below the equilibrium price, some consumers may be willing to pay a higer price than legal. This is the existence of a 'black market'.
Determining black market price:
draw a horizontal line from the legally set price to the supply curve. from this point, draw a vertical line to the demand curve. from this point draw an horizontal line to the y axis.
Price Floor (minimum price)
governments set minimum prices for goods so that producers can improve their income. Prices can go higher but not lower.
When a price floor or ceiling are removed what happens to price of goods or service?
price will return to equilibrium price.
when the government intervenes in the economy by shifting either supply or demand what is it called?
the government is "working throug the market".
Cobweb Theorem
the graphical interpretation of the condition set when high prices prompt increase in production which then prompts decrease in prices which then prompts dcrease in production which increases prices, which increases production and so on.
on the Supply and Demand graph, the units supplied will be expressed by ______.
The equilibrium point at which the Supply and Demand curve meet.
On the Supply and Demand graph the amount of goods produced at a particular price point which is greater than or equal to the equilibrium Price is expressed by _______
The point at which the horizontal line drawn from the price intersects with the Supply Curve or the horizontal line drawn from that point (called the equilibrium point) to the x axis.
