What is an Economy?
• The way goods, services & money flow through an economic system
The Circular Flow describes how goods, services & money flow through a market economy
![Page 3: How the U.S. Economy works](https://reader036.vdocuments.us/reader036/viewer/2022081505/5a4d1b247f8b9ab059996619/html5/thumbnails/3.jpg)
2 Sides of a Market Economy
• Consumers decide what to BUY!– Demand side of economy
• Producers decide what to SELL (MAKE)– Supply side of economy

4 Factors of Production• Resources used to make goods & services1) Land- all basic natural resources2) Labor- human work/labor3) Physical Capital- previously produced goods4) Human Capital education, skills, etc…
To open a coffee shop:
Land = Beans & Rent store
Labor = worker Physical Capital =Coffee Machine
Human Capital = Skills of workers & owner of store

where any good or service is sold
Product & Factor Markets
Product Market:
Factor Market: where factors of production are exchanged
Consumers use product market
Producers use factor market

Gross Domestic Product
Measuring Economic Growth
![Page 10: How the U.S. Economy works](https://reader036.vdocuments.us/reader036/viewer/2022081505/5a4d1b247f8b9ab059996619/html5/thumbnails/10.jpg)
Measuring the Circular Flow• The total dollar value of economic output of the
circular flow is called Gross Domestic Product (GDP)
• The U.S. attempts to maximize GDP– Higher GDP growth leads to job creation

GDP growth: what is too high?
• The economy has an upper and lower “speed limit” of growth
• Too fast: If GDP grows above 5.0% per year, the economy may experience inflation– Prices rise
• Too slow: If GDP grows below 2%, not enough jobs are created– Unemployment rate increases
![Page 12: How the U.S. Economy works](https://reader036.vdocuments.us/reader036/viewer/2022081505/5a4d1b247f8b9ab059996619/html5/thumbnails/12.jpg)
2012 = + 2.2%
2013 = + 1.5%2014 = + 2.4%
2015 = + 2.1%
GDP growth too slow to create enough jobs!

What goods count in GDP?
• Dollar Value of all FINAL new goods & services produced in USA over one year– Imports do not count– Used goods do not count
• Must avoid “double counting” in GDPExample: Steel used in automobiles
Count value of the entire car (final good)—not the parts

Slow GDP Growth U.S. Economy in 2015
Factors Causing Slow Growth?
Recessions in EuropeSlow Growth in ChinaCollapsing Oil Prices => USA layoffsUnderemployment of Human Capital Declining Labor Force Participation

GDP does NOT Measure:
• Leisure time– Vacation Days: Europe get many more than U.S. workers
• Hours Worked:– Work 80 hours vs. 40 hrs per week => GDP goes up
• What you produce– Guns vs. butter: all products count the same!
