Simple Interest Formula

I = Prt
Where:
  • P = Principal Amount
  • I = Interest Amount
  • r = Rate of Interest per year in decimal; r = R/100
  • R = Rate of Interest per year as a percent; R = r * 100
  • t = Time Periods involved

Definitions: 

Personal Consumption Expenditures PCE: Measures price changes of consumer goods and services.

Consumer Price Index CPI: Examination of the wighted average price of a basket of consumer goods and services. Used to assess price changes to the price of living, and used in statistics to identify periods of inflation or deflation.



Formulae: 

Final Return = [(Final Price - Initial Price/ Initial Price)]

Expenditure Approach to Measuring GDP:
GDP = C + I  + G + Xn

Income Approach to Measuring  GDP:
GDP = W + I + R + P

GDP Deflator: A price used to adjust nominal GDP to real GDP:
• Real GDP: (Nominal GDP/GDP Deflator)(100)
• GDP Growth Rate: [(Current Year's GDP - Last Year's GDP)/Last Year's GDP)(100)]

Inflation Rate Via Consumer Price Index (CPI): [This Year's CPI - Last Year's CPI)/Last Year's CPI)(100)]

Real Interest Rate = Nominal Interest Rate - Inflation Rate

Unemployment Rate = [(Number of Unemployed/Number in the Labor Force)(100)]

Money Multiplier = (1/RRR)

Quantity Theory of Money: MV = PY, Explains how changes to money supply impact price level assuming fixed levels of output and fixed velocity of money.

Spending Multiplier = (1/1-MPC) OR (1/MPS)

Tax Multiplier = MPCMPS, Tells you how much spending will result from an initial change in the level of taxation. When taxes decrease, spending increases and vis versa.

Velocity of Money: VT = (PT/M)
Where:
V T is the velocity of money for all transactions in a given time frame
P is the price level
T is the aggregate real value of transactions in a given time frame
M is the total nominal amount of money in circulation on average in the economy

Thus PT is the total nominal amount of transactions per period

Alternate Calculation: V = (PQ/M)
Where:
V is the velocity for transactions counting towards national or domestic product
PQ is nominal national or domestic product

The Crisis: A Classical Financial Panic

· A financial panic occurs when providers of short-term credit (think depositors in a bank) suddenly lose confidence in the ability to repay; providers of short-term credit then quickly withdraw their funds.

IS-LM Hicks-Hansen Model: Shows the relationship between interest rates (ordinate)
and assets market (also known as real output in goods and services market plus money market, as abscissa). The intersection of the "investment--saving" (IS) and "liquidity preference-money supply" (LM) curves models "general equilibrium" where supposed simultaneous equilibrium occurs in both interest and assets markets.

Ben Bernanke:
The Role of Monetary Policy
· Most evidence suggests otherwise:
-International comparisons: For example, the United Kingdom had a house price boom during the 2000s despite tighter monetary policy than the United States.
-Size of the bubble: Changes in mortgage rates during the boom years seemed too small to account for the magnitude of house price increases.

Nominal Interest Rates: Either one of two distinct things, 1) the rate of interest before adjustment for inflation (in contrast with the real interest rate), or 2)for interest rates "as stated" without adjustment for the full effect of compounding (also referred to as the nominal annual rate). An interest rate is called nominal if the frequency of compounding (e.g. a month) is not identical to the basic time unit (normally a year). The relationship between the real interest value r, the nominal interest rate value R, and the inflation rate value i is given by: (1 + r) = (1 + R)/(1 + i), When the inflation rate i is low, the real interest rate is approximately given by the nominal interest rate minus the inflation rate, i.e., (r is approximately R - i).

Forrex Currency Correlations:
-GBP/USD (British Pound, sterling, etc...) has a negative correlation to the USD/CHF (Swiss Franc) and a positive correlation to the EURO/USD.
-Base currency is the first currency listed in the pair, the second is the quote currency. The currency pair is an indicator of the amount of the quote currency one must have to purchase one unit of the base currency.
-Purchase of pair on Forrex is simultaneously the purchase of one currency and the sale of another. You are buying the base currency with a sale of the quoted currency. -During a sale, you sell the base currency and receive the quote currency. The ask (sell price) is the amount made on dale of one unit of base.
-Major currency pairs that involve the USD but where the USD is not the base currency include EUR/USD (Euro and U.S. dollar); GBP/USD (British pound and U.S. dollar); and AUD/USD (Australian dollar and U.S. dollar).


Math for Economics:

total cost formulas, average variable, marginal cost, and more, (work out your own algebra to find alternatives):
Average Total Cost (ATC) = Total Cost / Q (Output is quantity produced or ‘Q’)Average Variable Cost (AVC) = Total Variable Cost / QAverage Fixed Cost (AFC) = ATC – AVC
Total Cost (TC) = (AVC + AFC) X Output (Which is Q)
Total Variable Cost (TVC) = AVC X Output
Total Fixed Cost (TFC) = TC – TVC
Marginal Cost (MC) = Change in Total Costs / Change in Output
Marginal Product (MP) = Change in Total Product / Change in Variable Factor
Marginal Revenue (MR) = Change in Total Revenue / Change in Q
Average Product (AP) = TP / Variable Factor
Total Revenue (TR) = Price X Quantity
Average Revenue (AR) = TR / Output
Total Product (TP) = AP X Variable Factor
Economic Profit = TR – TC > 0
A Loss = TR – TC < 0
Break Even Point = AR = ATC
Profit Maximizing Condition = MR = MC
Explicit Costs = Payments to non-owners of the firm for the resources they supply.


Discounted cash flows[edit]

The discounted cash flow formula is derived from the future value formula for calculating the time value of money and compounding returns.
Thus the discounted present value (for one cash flow in one future period) is expressed as:
where
  • DPV is the discounted present value of the future cash flow (FV), or FV adjusted for the delay in receipt;
  • FV is the nominal value of a cash flow amount in a future period;
  • r is the interest rate or discount rate, which reflects the cost of tying up capital and may also allow for the risk that the payment may not be received in full;[5]
  • n is the time in years before the future cash flow occurs.
Where multiple cash flows in multiple time periods are discounted, it is necessary to sum them as follows:
for each future cash flow (FV) at any time period (t) in years from the present time, summed over all time periods. The sum can then be used as a net present value figure. If the amount to be paid at time 0 (now) for all the future cash flows is known, then that amount can be substituted for DPV and the equation can be solved for r, that is the internal rate of return.
All the above assumes that the interest rate remains constant throughout the whole period.
If the cash flow stream is assumed to continue indefinitely, the finite forecast is usually combined with the assumption of constant cash flow growth beyond the discrete projection period. The total value of such cash flow stream is the sum of the finite discounted cash flow forecast and the Terminal value (finance).

Continuous cash flows[edit]

For continuous cash flows, the summation in the above formula is replaced by an integration:

where  is now the rate of cash flow, and .
