02/04/16         Inflationincrease in prices

Formula- Price Index in 2 years - Price Index in 1 year / Price Index in 1 year

Hurt by Inflation:
  1. Savers
  2. Lenders/ Creditors
  3. People who are on a fixed income - (elderly, wellfare)
Helped by Inflation:
  1. Delators; people who owe money; borrowers
Cost of Living Adjustments- automatic wage increase when inflation occurs (New York and California due to standard of living)


GDP Gap- the amount by which actual GDP falls short of potential GDP

Okun's Law- For every 1% in which actual enemployment rate exceeds the NRU, a GDP of about 2% occurs.
                    - Ex. In 2012 the unemplyment for Mexico was 7.4%. The NRU is 6%. Calculate GDP Gap.
(Actual) 7.4 - 6 (NRU) = 1.4 X 2 = 2.8

Rule of 70- used to determine how many years it takes for a value to double; given a particular annual growth rate.
                  - Ex. If you put $20,000 in the bank, and it earns a yearly interest of 7%. How many years will it take for your income to double? 10 years due to rule of 70.


02/01/16      Gross Domestic Product Cont...

National Income- (Personal Household + Taxes + Gov't Transfer Payment)

Nominal GDP- Value of output produced in current year prices (Price X Quantity)

Real GDP- value of output produced in constant based year prices.


                - adjusted for inflation (base year X Quantity)
                - real GDP to measure economic growth
                - measure increase in prices (inflation) use Nominal GDP
                - can increase from year to year if either price quantity increases
                - real increases only if output increases
                - earliest year ALWAYS = base year if not stated.


Nominal to Real GDP
(Nominal GDP / Real GDP) X 100

CPI- (most commonly used) measures cost of market basket of goods of a typical urban American family.
          - Cost of Market Basket of goods in a given year / "  " of goods in a based year.







01/28/16    Gross Domestic Product-  
the monetary value of all goods and services produced within a nation's geographic borders over a specified period of time.

Formula- C + IG + G + Xn

C- Personal Consumption Expenditures [65%] (Tory Burch, Louis Vuitton, etc..)

IG- Gross (total) Private Domestic Investment [17%] (House being built but not sold)
1.) Factory Equipment Maintenance   2.) New Factory Equipment   
3.) Construction of Housing    4.) Unsold Inventory Built

G- Government Spending: [20%] (Teacher salary in a year)

Xn- Net Exports (Exports - Imports)

GNP- Total Market Value of all final goods and services by citizens of that country on its land or foreign land.     Ex. Nike using Indonesia to make shoes.

NDP- Net Domestic Product (GDP - Depreciation)

NNP- Net National Product (GNP - Depreciation)

GNP- Gross National Product (GDP + Net Foreign Factor Payment)

Let's not forget Price Ceiling & Price Floors!

*There is no better way to understand this than with a visual representation!




Hey Guys! So to better understand the business cycle, here is some very helpful photos(:




01/14/16      Elasticity of Demand:
the measure of consumer reactions to price changes.

Elastic Demand- Demand sensitive to change in price E > 1  
                           - NOT a necessity
                           - Available substitutes

Inelastic Demand- Not very sensitive E<1
                             - Necessity
                             - Few or no substitutes

Unitary Demand- ALWAYS equal (=) to 1





Price Elasticity of Demand- (PED)
1. Quantity (new-old)
2. Price (new-old /old)
3. (%change in quantity demanded / % change in price)



Total Revenue- Total amount of money a firm receives from selling goods and services.
Formula- (price x quantity)


Production Costs-

Fixed Cost- a cost that doesn't change no matter the quantity produced.
                  - Ex. rent, mortgage, insurance, salaries
Variable Cost- a cost which rises/ falls depending upon how much is produced.
Marginal Cost- a cost of producing 1 more unit of a good.
