Adam Smith: Wealth of Nations Laissez Faire: “hands off” Invisible Hand: The economy will regulate itself

Karl Marx: Communist Manifesto & Das Kapital Constant struggle between workers & owners Workers add value to goods but do not receive the profits  against market economies

John Maynard Keynes (Keynesian Theory) The General Theory of Employment, Interest and Money  Aggressive Fiscal Policy  Written after the Depression  Cut Taxes while increasing government spending  This will increase deficit spending  Gov’t spending more than it is taking in

 In the United States mixed economymixed economy  Three sectors, or elements, that interact: ◦ Households ◦ Businesses ◦ Government  Economists use the CFM to explain the interaction among these three sectors.  Each sector of the economy contributes to another.

Household & Firms – Factor Market 1.Where firms purchase or rent land 2.Firms hire workers & pay salaries for labor 3.Borrow money from households to purchase capital households interest or profits in return. Product Market 1.Households purchase products made by firms

Government in the Factor Market 1. Government purchases land, labor, & capital from households 2. Government collect taxes from firms. Government in the Product Market 1. Government purchases goods & services = building, telephones, computers, fax machines 2. Government provides goods & services = roads 3. Government collect taxes from households

 Gross Domestic Product (GDP): The total market value($ value) of all the goods & services produced within the borders of a nation during a specified period.  Usually reported on an annual basis ◦ Per Capita GDP: A nations GDP divided by its population  Consumer Price Index (CPI): Calculated each month by the Bureau of Labor Statistics ◦ It measures the change in prices (inflation) of a “market basket”  Ex. Food, housing, medical care, entertainment

 NOT a regular, predictable, or repeating phenomenon like the swing of the pendulum of a clock.   Its timing is random & unpredictable  A business cycle has four phases.

 Expansion  Contraction  Trough  Peak

 speedup in the pace of economic activity or Rise in GDP  Recovery: right after a trough, economy is getting better  Prosperity: right before a peak, economy is at its best  economic growth

 slowdown in the pace of economic activity  Economic decline marked by falling GDP  Recession: 6 straight months of contraction  Depression: Especially long contraction

 lower turning point of a business cycle, where a contraction turns into an expansion  GDP stops falling

 upward turning of a business cycle  When GDP stops rising **A trough & peak both represent a turning point in the business cycle**

 The National Debt is the total amount of money the Federal Government owes to treasury bondholders. A bond is essential an IOU issued by the government as a way for them to borrow money.

 When all other things equal, as the price of a good or service increases, the quantity demanded will decrease. ◦ The opposite is also true. As the price of a good or service decreases, the quantity demanded will increase ◦ TRANSLATION:  THE MORE EXPENSIVE SOMETHING IS, THE LESS PEOPLE WILL WANT TO BUY IT…DUH!!!!!! ◦ CONSUMERS HAVE A “PRICE MOTIVE”

The demand curve has a negative slope, consistent with the law of demand.

 When all other things equal, as the price of a good or service increases, the quantity supplied will increase & vice versa.  TRANSLATION:  IF PEOPLE ARE WILLING TO PAY A HIGH PRICE FOR AN ITEM, PRODUCERS ARE GOING TO MAKE MORE OF THAT ITEM TO INCREASE PROFIT.  SUPPLIERS HAVE A “PROFIT MOTIVE”

The supply curve has a positive slope, consistent with the law of supply.

 In economics, an equilibrium is a situation in which: ◦ No change ◦ Quantity Demanded (QD) equals Quantity Supplied (QS) ◦ It is where the supply curve intersects the demand curve ◦ Market clearing price: where the price of the item is set

Equilibrium occurs at a price of $3 & a quantity of 30 units.

 A shortage occurs when quantity demanded exceeds quantity supplied. ◦ A shortage implies the market price is too low.  A surplus occurs when quantity supplied exceeds quantity demanded. ◦ A surplus implies the market price is too high.

 A change in any variable other than price that influences quantity demanded produces a shift in the demand curve or a change in demand.  Factors that shift the demand curve include: ◦ Change in consumer incomes ◦ Population change ◦ Consumer preferences ◦ Prices of related goods:  Substitutes: goods consumed in place of one another  Complements: goods consumed jointly

This demand curve has shifted to the right. Quantity demanded is now higher at any given price.

 Things other than price that influence quantity supplied produces a shift in the supply curve or a change in supply.  Factors that shift the supply curve include: ◦ Change in input costs  Things that go into making the product (Factors of production) ◦ Increase in technology  Assembly line, Innovations, Inventions ◦ Change in size of the industry  More/less people that are actually making the product

For an given rental price, quantity supplied is now lower than before.

The shift in the supply curve moves the market equilibrium from point A to point B, resulting in a higher price & lower quantity.

 A price ceiling is a legal maximum that can be charged for a good. Price cannot go above the ceiling. ◦ Results in a shortage of a product ◦ Common examples include apartment rentals & credit cards interest rates.  A price floor is a legal minimum that can be charged for a good. Price cannot go below the floor. ◦ Results in a surplus of a product ◦ Common examples include soybeans, milk, minimum wage  **you can not go above the ceiling or below the floor**

A price ceiling is set at $2 resulting in a shortage of 20 units. Always creates a shortage

A price floor is set at $4 resulting in a surplus of 20 units. Always creates a surplus
