It is not true that “everybody gets an A in Econ 100” It is not true that “everybody gets an A in Econ 100”. This is an actual quote from a student (who received a D+) To pass you need 50. For an “A” you need 90-92.

Enough about grades

Lecture Notes. Fairly detailed, regularly updated. But no substitute for lectures Study tips. Study questions: very important, then lecture notes, then the book. Use the office hours if you need help. Exams Multiple choice questions + a few short answer questions- simple math calculations. No essays.

After Econ100 Econ201 Microeconomics Studies the behavior of individual units (consumers and firms); the demand and supply of individual goods and services. More abstract/mathematical than Econ202 Econ202 Macroeconomics Studies aggregated indicators such as GDP, unemployment, and inflation, tries to understand how the whole economy functions. Always in the news, and on TV: economic growth, exports, imports, central bank. Interest rate, current account deficit, inflation, exchange rates, etc.

A 5 minute lecture on “What is economics?” Now… A 5 minute lecture on “What is economics?”

Economics is about the allocation of scarce resources. Example : Your best friend invites you to a open buffet brunch. Money is no object; you can eat as much as you want for free. Time is not an obstacle; it is Saturday, you have all afternoon and would enjoy spending it in the company of your friend. What is the scarce resource here?

If there is scarcity then you have to make choices. The trade-off principle: When there is scarcity, then having more of one good thing means having less of another.

Now something really confusing… Economics starts with the assumption that people have well- defined objectives/goals and tend to choose the correct way to achieve them.  More specifically, economics assumes that people are rational! Which means people follow this simple rule: Do activity x if and only if B(x) > C(x), B(x) is the benefit of activity x (to the individual) C(x) is the cost of activity (to the individual)

A very short case study Now it is your turn

You are the general manager of IL JK company You are the general manager of IL JK company. The company provides extermination services (böcek ilaçlama). There are some administrative personnel who cannot be fired and … 196 workers who do the actual extermination work and can be fired.

More information… The company started 5 years ago. It is owned by three families. The work requires only a low level of skills so that each worker requires only one week of training. Almost all workers have been with the company for 3 to 5 years. The company pays its workers more than the minimum wage. The workers’ wages, including overtime, are between TL 1,500 and 1,900 per month. The minimum wage in 2013 was about 970 TL. The company gives its workers all the benefits required by law.

Current situation Until recently, the company was very profitable. As a result of the continuing recession, however, there has been a big decrease in profits though the company is making profits.

The big decision You will soon have a meeting with the owners and your management team must decide how many workers to lay off. IL JK’s Finance Department has prepared the following forecast of annual profits:

Data Number of workers who will continue to be employed Expected annual profit in TL, millions 0 (all the workers will be laid off) Loss of 8 50 (146 workers will be laid off) Profit of 1 65 (131 workers will be laid off) Profit of 1.5 100 (96 workers will be laid off) Profit of 2 144 (52 workers will be laid off) Profit of 1.6 170 (26 workers will be laid off) 196 (no layoffs) Profit of 0.4

Your recommendation? I recommend continuing to employ ______ of the 196 workers in the company. Why? Provide a brief justification for you decision: _______________________________________

Please… Write your name exactly as it appears on KU records. Make sure that I can read your handwriting. I am interested in the WHY part of your answer.

Your recommendation: I recommend continuing to employ ______ of the 196 workers in the company. Why? A brief justification for you decision: ________________ ___________________________________________________
