The student with the most extra credit points at the end of the quarter will receive a 5 percentage point boost to grade Others will receive less than 5

percentage points, formula to be determined at the end of the quarter

Today: An introduction to economics

What is economics? Money? Finance?

Today: An introduction to economics

What is economics? Money? Finance? Part of the study of economics

involves money and finance As we will see over the next 10

weeks, economics covers many topics

An introduction to economics

What is economics? Frank and Bernanke (FB) define

economics as “the study of how people make choices under conditions of scarcity and of the results of those choices for society” (p. 4) Key word to remember: “choice”

Why do we make the choices that we do? 7 core principles of economics

Scarcity Cost-benefit analysis Incentives matter Comparative advantage Increasing opportunity cost Equilibrium Efficiency

Scarcity Nobody has everything that he/she

wants To get more of something good,

something else must be given up Most people seem to have most things

that are “highly valued” Good thing We will establish what “highly valued”

means

Cost-benefit analysis

Cost-benefit analysis: Think marginal

Criterion for doing something Marginal benefit should be at least as

great as marginal cost

Incentives matter

Cost-benefit analysis is important in predicting individual behavior Microeconomics focuses on individual

behavior For macroeconomics topics: Wait until

Econ 2

Comparative advantage

In simple economies: Everyone does best with specialization and trade

In more complex economies: ON AVERAGE, everyone does best with specialization and trade Example: When trade opens up, one

person may have to change jobs and earn less; 100K people pay $1 less on the good

Increasing opportunity cost

Use resources with the lowest opportunity cost first

As with cost-benefit analysis, remember to think in terms of marginal

Equilibrium

Two types for this class Market equilibrium Nash equilibrium (game theory)

No unexploited opportunities for individuals in either type of equilibrium

Efficiency

The more efficient an economy is, the more consumption can occur

If an economy improves efficiency, each person’s consumption can increase

Caution: Equilibrium and efficient sometimes are the same; sometimes they are not

Summary

Crashers: Keep showing up until I have more information

Three tests and extra credit determine your grade

7 core principles will be the focus of Econ 1

For Wednesday Read the syllabus:

http://econ.ucsb.edu/~hartman/ Buy the Frank/Bernanke text book If needed, buy a non-programmable four-

function or scientific calculator that is NOT a communication device

Read Chapter 1 Read appendix if you think that your graphing skills

are weak Try to think like an economist

In the future… If you must leave early, please sit near

an exit and leave quietly at least ten minutes before the end of lecture

Otherwise, please do not pack your belongings until I am finished with the lecture

Important announcements may be missed if too many people are making noise

See you on Wednesday
