Fundamental Economic Concepts

What is Economics? - The study of mankind’s unlimited desires in a world of limited resources. - Economics is a social science, dealing with how people react to changing variables. -Economists form theories, based on economic models in which they manipulate variables. -These theories, models and variables are used to describe what is (Positive Economics) and what ought to be (Normative Economics).

What is the Economy?

Is It True…….? Do you always seem to want more regardless of your economic situation? Is it greed or positive thinking?

Why Do We Study It? 1. Description 2. Analysis 3. Explanation 4. Prediction What? or How Much? How? or Why? When? OR…

Why do we study Economics? So we don’t get screwed.

3 Basic Economic Questions Who will consume services? How will goods and services be produced? What goods and services will be produced?

Scarcity Situation that occurs when wants are greater than available resources. Scarcity is the fundamental problem in economics.

In this classroom, is/are _________ scarce? Desks? Water? Books? Gasoline? Jolly Ranchers? … Good looking economics instructors? But not in the hallway… Wants are satisfied by available resources No want for it in classroom, but outside… yes Wants exceed available resources

Good looking economics instructors?

Scarcity Choices WHAT to produce Unlimited Wants Limited Resources HOW to produce FOR WHOM to produce

We must consider… Examples: Shelter is a need, a mansion is a want. Food is a need, a large pizza is a want.

Imagine a scenario where… …we take an all-expenses- paid class trip to…

Australia!

Our plane is forced to make a “water landing,” and we are able to swim to an uncharted island. What will we need to do and what will we want to do? What questions will we have to answer?

Scarcity forces us to ask the following questions… WHAT to produce? HOW to produce? FOR WHOM to produce?

FACTORS OF PRODUCTION Land – all gifts of nature Labor – human efforts and abilities Capital – tools, equipment, space Entrepreneurship – risk taking, ideas ◦ **The “spark” or driving force of the economy**

Land Natural resources needed to produce goods and services ◦ E.g. soil, minerals, water, timber, fish, and wildlife

Labor Includes time and energy of a person ◦ Also includes knowledge and skills a person has and uses

Capital Anything produced in an economy that is used to produce other goods and services When tools and buildings are used as capital they are called capital goods Money ◦ Financial capital—money available for investing or spending

Entrepreneurs What is an Entrepreneur? Why are they so important? ◦ Risk takers ◦ Doing something new with existing resources How many can you name? ◦ Bill Gates, Steve Jobs, Thomas Edison, Ben Franklin, etc.

Is anything actually free???? If something is……. ◦ Bogo ◦ Free ◦ Buy one get one half of ◦ Then what?????????? ◦ TINSTAAFL ◦ There Is No Such Thing As A Free Lunch

Want-Satisfaction Chain Wants ◦ Have to want something Production ◦ Combine land, labor, and capital Distribution ◦ Move product to a place of sale Consumption ◦ Act of buying or using a good or service

CIRCULAR FLOW

Utility The satisfaction that consumption of a good or service provides

DIMINISHING MARGINAL UTILITY As you consume additional units of a good, at some point each additional unit will begin providing less utility than the one before it.

Paradox of Value Water vs. Diamonds Monetary Value ◦ Must be scarce ◦ Must give utility Are diamonds scarce? Do they give utility? Conspicuous consumption ◦ Examples?

Cost – Benefit Analysis Question? : What do you want RIGHT NOW?

Cost – Benefit Analysis Follow up question? : Why don’t you go get it?

Cost – Benefit Analysis We all make decisions in our own self-interest All decisions come with certain trade-offs and alternatives THERE IS NO SUCH THING AS A FREE LUNCH!!! SeinfeldSeinfeld example Opportunity Cost: the next-best alternative given up when making a choice

Opportunity Cost VS.

Marginal Cost Marginal = Additional, next Additional cost vs. additional benefit We constantly engage in marginal analysis

Production Possibilities Frontier Guns (thousands) Butter (tons) All possible combinations of two products that can be produced when employing 100% of available resources.
