The Economic Way of Thinking

What is economics? • Economics is the study of how

people choose to use their limited resources to satisfy their seemingly unlimited wants.

How does economics affect your life?

Describe what economists do. • Economists collect and interpret

information about economic activity.

• They conduct surveys, construct models and make predictions about how we use our resources and spend money.

• They also analyze the possible and actual economic effects of government actions.

• They often specialize in different branches of micro- and macroeconomics.

What is microeconomics?

• Microeconomics is the study of the economy at the level of individuals, households, and businesses.

• It is concerned with the supply and demand of goods and services, the determinants of price, consumer behavior, and the different types of businesses.

What is macroeconomics? • Macroeconomics is the study

of the workings of the economy as a whole.

• It is concerned with important aspects of national and global economic activity, such as GDP, unemployment, economic growth, national debt and international trade.

• It is particularly interested in the effect of government actions on economic activity.

What is positive economics? •Positive economics is the branch of economics that

uses objective analysis to find out how the economy actually works.

• It is concerned with studying the economy as it is, not as it ought to be.

What is normative economics? • Normative economics is the

branch of economics that makes value judgments about the economy.

• Its focus is on which economic policies should be implemented.

What is scarcity? •Scarcity is the condition that results from the fact that people have limited resources but unlimited wants.

What is “opportunity cost?” • Opportunity cost is the

value of the next best alternative that is given up when making a choice.

• It is a measure of what you must give up in order to get what you want.

Explain how scarcity (of goods, e.g.) forces choices/ trade-offs.

• Limited resources force people to make choices and face trade-offs when they choose

• Sometimes these choices are binary in nature. You pick either A or B. If you pick A, you do not get any B.

• Other times it is a question of how many of each item you choose. Decisions are based on one more or one less of some item. In this instance you can be said to be deciding at the margin. This is sometimes referred to as marginal utility.
