Resources
A resource is any item that is used to produce goods and services

Capital - the tools, machinery, infrastructure, and knowledge used to produce goods and services
Entrepreneurial Ability - the talent or ability to combine land, labor, and capital to produce goods and services.

Resources are the foundation for all human actions.
How resources are used is one of the most important issues any society faces
Every person’s and every society’s standard of living depends on the choice they make about how to use their resources
Our problem is that resources are scarce

Scarcity
Condition in which wants are hereafter than the limited resources available to satisfy those want
Scarcity will always exist
Scarcity affects every one
Relative scarcity compares the scarcity of one thing relative to that of another
Scarcity forces us to make choices about how we allocate our resource

Economics provides the tools that describe how people make choices when faced with scarcity
By mastering the tools of economics, you will gain insight into what drives decision making by individual, businesses, and governments
Knowing how and why choices are made gives you the ability to influence and shape your world.
