Unit 2: Circular Flow, GDP, Real GDP, and Nominal GDP

Real GDP:

What is Peak?

- the highness point of GDP
- has the lowest unemployment & greatest spending

What is Expansion

- " Recovery Phase"
- where real GDP is increasing, which cost spending to increase and unemployment to decrease

What is Contraction/ Recession

- where real GDP declines for six months
- increase in unemployment and reduction in spending

What is Trough?

- the lowest point of real GDP
- it has the highest point of unemployment and highest amount of spending 

Circular Flow:


Gross Domestic Program (GDP)


What is a Circular Flow Diagram

- it represents the transaction in a economy

What is a Product Market?

- it is a place where goods and services are produced by business

What is a Factor Market?

- a place where households sell resources and business by resources

What is a Firm

 - an organization that produces goods and sales

What is a Household?

 - a person or a group of people that shares an income

What is GDP

- gross domestic program
- its the total market value of all final goods and services produced in a within country's border in a given year

What is GNP?

- gross national product
- the total market value of all final goods and services by citizens of that country on its land or foreign land


Gross = Total


Included in GDP:

C - personal consumption expenditures
IG - Gross private domestic investment
  1. Factory
  2. Factory equipment
  3. Construction of Houses
  4. Unsold inventory of products built in a year
G- government spending (can buy anything & everything)
Xn - Net Export (Exports - Imports)

C + IG + D + Xn ( Ex - Im)


Not Included in GDP:

1. Intermediate goods - good that requires further processing before it is ready for final use 

(ex. car parts)

2. Used of secondhand goods
     - trying to avoid double counting

3. Purely Financial Transactions 
(ex. stocks & bonds)

4. Illegal Activities 
(ex. drugs)

5. Unreported business activity 
(ex. unreported tips)

6. Non-market Activity  
(ex. volunteering, babysitting, or any work performed for yourself)

7. Transfer Payment 
- public (social security, welfare)
- private (scholarships -money transferred from donor to you)






What is Nominal GDP

- It's the value of the output produced in current prices
- can increase from year to year if either output or price increases.
- If we want to measure price increases known as inflation, we use nominal GDP.

What is Real GDP?

- It's the value of output produced in constant based year price.
-can increase from year to year only if output increases.
- If we want to measure economic growth, we use real GDP.
- injected for inflation
- base does not move



What is GDP Deflator?

- It is a price index use to adjust from nominal to real GDP.
  ( N / R x 100)
- if the base year, GDP Deflator with always = to 100
- In years after the base year, GDP is greater than 100
- In the particular year, GDP is less than 100




What is Consumer Price Index

- It is the most commonly use of inflation

What is Inflation Rate?





GDP Formulas

Nominal: Price x Quantity
Real: New Quantity x Base Price
Deflator: (Nominal / Real) x 100
Inflation: ((New Deflator - Old Deflator) / Old Deflator) x 100
Unemployment Rate: # of Unemployment / (# of employed + Unemployed) x 100
Expenditure : C + Ig + G + Xn
Income: W + R + I + P + statistical adjustment

Budget: (Gov. purchase of goods & services) + (Gov. transfer payment) - (Gov. Tax&Fee collection)
     + deficit, - surplus
Trade: Export - Import
     - deficit, + surplus
National Income: 1. (Compensation of Employees) + (Rental Income) + (Interest Income) + (Corporate Income) + (Properties Income)
     2. (GDP) - (Indirect Business Taxes) - (Depreciation) - (Net Foreign)
Disposable Income: (Nat. Income) - (Personal Household Taxes) + (Gov. Transfer Payment)

Unit 1: Supply & Demand

Chapter 3&4 - Supply and Demand

Elasticity of Demand 

   - a measure of how consumers react in a change of price

What is Elastic Demand?

- demand that is very sensitive to a change in price
- E > 1
- the product is not necessity and there are available substitute 

ex: Soda
      Steak
      Candy
      Fur Coats

What is Inelastic Demand? 

- demand that is not sensitive to a change in price
- E < 1
- there are few to no substitute product is necessity
- people will always buy

ex: Gas
      Salt
      Milk
      Insulin/Medicine

Price Elasticity of Demand (PED)

Step 1: Quantity
(New Quantity - Old Quantity) / Old Quantity

Step 2: Price
(New Price - Old Price / Old Price) 

Step 3: PED
Δ in quantity demanded / % Δ in price


Unit 1: Scarcity, Factors of Production & PPGs

Chapter 1-2: Scarcity, Factors of Production & Production Possibilities Graphs

What is Macroeconomics?

   - the study of economy as a whole 
   - the BIG picture
   - "Can't see the forest because of trees"

Ex: Supply & Demand
      International Trade
      Minimum Wage











What is Microeconomics

  - study of individual or specific unit of the      economy

Ex: Market Structure
       Business Organization











What is Positive Economics

- it attempts to describe the world as is.
- very descriptive, collects and presents facts
- "What is" = facts

What is Normative Economics?

- it attempts to prescribe how the world should be
- very perspective
- "ought to be", "should be" = opinion based

What are Needs

- basic requirements for survival

ex: Food, Water, Shelter, Clothes

What are Wants

- Desire of citizens

What are Goods

- A tangible commodities (touch/feel)
-can be bought, sold, produce

ex: Capital Goods - items used in a creation of other goods. 
        ( trucks, factory, machine)
      Consumer Goods - goods that are introduced for final use of the consumer.

What are Services

- work that is performed for someone

ex: haircut, concert, going to school

What is Scarcity?

- the most fundamental economics problem facing all society
- how to satisfy unlimited wants with limited resources
- involves a choice

What are Shortage?

- where we have quantity demanded is greater than quality service

What are the Factors of Production?

  1. Land - natural resources
  2. Labor - work force, how much work is exerted
  3. Capital - physical capital tools, buildings, machines, trucks
  4. Entrepreneurship - innovative and risk taker  (owning your own business)
Capital.Entrepreneurship.Land.Labor !!!!

What causes the PPC/PPF to shift?

  1. Technological change
  2. Δ in resources
  3. Δ in labor force
  4. Economic growth
  5. Natural disaster/war
  6. More education on training

What is Trade-off?

-alternative that we give up whenever we choose one course of action over another

What is Opportunity Cost?

-the next big alternative

ex: travel, flight attendance

Production Possibilities Curve (PPC)

Production Possibilities Frontier (PPF)

Production Possibilities Graph (PPG)

-to show alternative ways to use an economic resources

Inside the Curve: Underutilization
                               Attainable
   (A)                       Inefficient
On the Curve:      Attainable
      (B,D,C)            Efficient
Outside the curve:Unattainable
       (x)                    Efficient











What are the Four Consumptions of PPG? 

  1. 2 resources (goods)
  2. Fixed resources (factors of production)
  3. Fixed technology
  4. Full employment of resources

What is Efficiency? 

- using the resources in such a way to maximize the production of goods and services

What is Allocative Efficiency?

- products being produced and the ones most by society

What is Productive Efficiency?

-products are being produced in the least costly way (any point on the PPC)

What is Underutilization?

- using fewer resources than an economy is capable of using
