Transcript of Economics

Resources are the foundation of an economy that are used to produce products and services.

There are four types of resources:
Factors of Production
What was the hardest purchasing decision you have ever made?
The most-valued alternative that was sacrificed when another option was selected.

When choosing between two high value options, this is the option that was not chosen.
Opportunity Costs
How do these factors impact price and demand?
What Impacts Price? What Impacts Demand?
What resources are needed to product automobiles?
Production Possibility Frontier:
Opportunity Costs
The social science of studying how people, both individually and in groups, decided to use scare resources to produce, distribute, and consume products and services.
Production Possibility Frontier:
Opportunity Costs
What products are in ghigh demand right now
Quantities of a particular good or service that consumers are willing and able to buy at different prices at a particular time.

Microeconomics (Small Scale)
An area of economics that studies the behavior and decision making process of individual consumers, companies, and industries.
what do you buy with your money and how much do you spend?
Macroeconomics (Large Scale)
An area of economics that studies the performance of the economy as a whole (both nationally and globally).

Macroeconomics examines the connection of unemployment, income, growth, gross domestic product, inflation and price levels and how they change.
what impact does our shopping habits have on others?
Land: (Natural Resources) such as water, soil, oil, minerals, and wood

Labor: (Human Resources) the physical and mental efforts people use to create goods and services

Capital: (Manufacturing Resources) the buildings, tools, and machines used to help to product goods and services.

Entrepreneurship: (Ideas) the imagination, innovative thinking, and managerial skills need to start and operate a business.
What happens if there is not enough food or water?
The inability to support and satisfy wants due to either a shortage or limited availability of a desired resource.

Wants > Resources
Example: Oil and Water
what is the best resource for producing energy?
Renewable Resources:
After a resource has been used, it can be replenished over time.

(solar energy, wood, and soil)

Non-Renewable Resources:
After a resource has been used, it cannot be renewed (it won't come back)

(fossil fuels, copper, gold)
If a farmer has to choose between planting corn and soybeans, what is the opportunity cost if he/she decided to plant corn? Soybeans?
A curve depicting all maximum output possibilities for two or more goods based on the use of available resources.

The PPF assumes that all inputs are used efficiently.
Represents the point at which an economy is most efficiently producing its goods and services and, therefore, allocating its resources in the best way possible.

It shows there are limits to production, so an economy, to achieve efficiency, must decide what combination of goods and services can be produced.
The Law of Demand:
The inverse relationship between the demand for a product and the price of the product.
Consumers will buy more gas if the price is low, and less if he price is high.
Change in Income
Availability or Prices of Substitutions
Availability or Prices of Complementary Goods
Change in Weather or Season
Change in the Number of Buyers
Changes in Styles, Tastes, and Habits
Change in Expectations

Demand Curve
Who has the most buying power?
What Impacts Price? What Impacts Demand?
Buying Power:
The quantity of goods and services person can buy with a given amount of money.
Diminishing Marginal Utility:
The where an additional unit of a product consumed is less satisfying than the one before it.
A good or service that can be replaces with a different good or service.
What happens to the demand of jelly if the price of peanut butter goes up?
Complementary Goods:
Products that are often used together or support each other.
Price Elasticity of Demand:
Consumers are less likely to purchase something at higher prices compared to lower prices
Market Demand:
The total number of individuals demanding a product or service in a given market at a particular time.
Changes in Demand
How does the demand for a product decrease?
Consumers are buying less of a product at all possible prices
What products are hard to find?
Quantities of a particular good or service that companies are willing and able to sell at different prices at a particular time.
Law of Supply:
The positive relationship between the quantity supplied and the price of the product.
If the price of gasoline increase, then the supply does as well.
How might these factors impact supply of a product?
What Impacts Supply?
Change in the Cost of Production
Change in Technology
Change in the Number of Producers
Change in Expectations
Market Supply:
The total supply of a product available in a market.
(adding the inventories of all companies together)

Small or minor changes in supply after a change in price
Predictions of the supply of chocolates that Godiva has at each price.
Godiva Chocolate
Chocolates Supply
Supply Curve
Changes in Supply
How does the supply of a product increase and decrease?
If the price of a product is low, then consumer will buy more of it thus reducing supply.

If the price of a product is high, then consumer will buy less of it thus increasing supply.
Why is this also called the market clearing point?
Supply and Demand
Is the price at which the amount of the supply is equal to the amount of demand. This is the price that "clears the market"
This is the point where the supply curve and demand curve intersect.
Supply and Demand
Supply and Demand
Market Shortage:

Binding Price Floor:
Setting the price floor above the equilibrium price

Non-Binding Price Floor:
Setting the price floor below the equilibrium price.
Supply and Demand
Price Ceiling:
A price ceiling is the highest legal price a product can be sold at.

Character: Your honesty and willingness to repay a debt.

Capacity: This is your ability to repay a debt.

Capital: The value of your processions. Includes available money from accounts.

If you borrow $1,000 at 9 percent for one year, what is the amount of interest owed?

I = $1,000(P) x 0.09%(R) x 1(T)= $90

If you borrow $1,000 at 12 percent for one month, what is the amount of interest owed?

I = $1,000(P) x 0.12%(R) x 1/12(T)= $10

Annual Percentage Rate (APR)-
Percentage cost of credit on a yearly basis. By law, all sales and loan credit must disclose the APR.

Changes in the Value of Money
The value of money is always changing.
The Buying Power of the U.S. Dollar
~ $28.00
Purchasing Power:
The amount of goods or services that can be purchased with a unit of currency.
What causes this change?
Changes in the Value of Money
An increase in the general price level of goods and services over a period of time.
When price level rise, each unit of currency buys fewer goods and services.
The price for a bottle of Coca-Cola in 1920 was 5 cents
The price for a bottle of Coca-Cola today is $1.29
The average price for a new car in 1960 was $2,275
The average price for a new car today is $32,890
Changes in the Value of Money
When inflation becomes extremely rapid or out of control.
An imbalance in the supply and demand for the money. This causes prices of goods and services to increase, while currency (money) loses its value.
Post WWI Germany (Weimar Republic) from 1921-1924
Pre-WWI: 1 USD = 4.2 German Marks
1924: 1 USD = 4,210,500,000,000 German Marks
Changes in the Value of Money
Cost-Push Inflation:
Demand-Pull Inflation:
The general rise in price levels of products and services due to increases in the cost of wages, raw materials, and other resources.
The rise in price levels due to the demand in an economy strongly outweighing its supply. When this happens, prices increase.
(Too many dollars chasing too few goods).
Changes in the Value of Money
A condition of slow economic growth (high unemployment) accompanied by a rise in prices (inflation).
A general decline in prices, often caused by a reduction in the supply of money or credit. This is due to a decrease in government, personal or investment spending.
What happens if consumers are not buying or investing?
Example: U.S. in 1970
Production and Productivity
In order for us to consume the things we love (food, music, clothing) we need someone to produce it.

Law of Diminishing Marginal Returns:
Negative Impacts on Production Increase:
If out of all stages in a production process, a company adds more of one stage, while holding all others constant, at some point the production process will produce lower per-unit returns.

An economic measure of a positive balance of trade, where a country's exports exceeds its imports.
An economic measure of a negative balance of trade in which a country's imports exceeds its exports.
Market Systems
A set of laws, institutions, and activities that guide economic decision making
Four fundamental questions:

What goods and services should be produced?
What quantity of goods and services should be produced?
How should goods and services be produced?
For whom should goods and services be produced?

Market Systems
The way nations answer the four basic economic questions determines their economic system.

Traditional system:
Relies on farming and simple barter trade

Market system:
Based on supply and demand with little government control

Command system:
Run by a strong centralized government
A tax imposed on imported goods and services to increase the price, making them more expensive to consumers.
Why do this?
Domestic Goods and Services:
grown, produced, or manufactured in a country then sold and consumed in the same country.
Imported Goods and Services:
grown, produced, or manufactured in one country then sold and consumed in another country.
How Does the Dollar Gain or Lose Value?
It's Just Paper!
Back Then...
The Gold Standard
A monetary system where a country's currency or paper money has a value directly linked to gold.
The United States stopped using the gold standard in 1933 and completely abandoned it in 1971.
The Gold Standard was replaced by Fiat Money (AKA the Dollar)
Fiat Money
currency that a government declares to be legal tender, but it is not backed by a physical commodity.
Gold Reserve Act 1934
Took away title to all gold and gold certificates that were held by the Federal Reserve Bank. The Gold Reserve Act of 1934 made the trade and possession of gold a criminal offense for the citizens of the United States. Sole title of this gold was given to the U.S. Treasury. It was not until 1975 that Americans could again own or trade gold.
Why is the US Dollar Used Considered the Global Currency?
1944 Bretton Woods Agreement
The world's developed countries met at Bretton Woods, New Hampshire, to peg the exchange rate for all currencies to the U.S. dollar because the United States held the largest gold reserves.
So What is the Dollar Actually Worth?
Short Answer:
Long Answer:
'full faith and credit of the United States Government'
Why use the US Dollar if it is worthless and backed by nothing?
Because it is actually backed by something...
Currencies (The Dollar) are used to obtain things like food, clothing, land, cars, etc.
So What If the Dollar Loses All of Its Value?
A sudden dollar collapse would create global economic turmoil. Investors would rush to other currencies, such as the euro, or other assets, such as gold and commodities.
Again, so why use the US Dollar as a global currency?
Oil and Oil Production
Land and Facilities
