Macroeconomics
The Philips Curve
Shows the relationship between inflation and unemployment
Involves the solving of macroeconomic issues; unemployment and inflation
Calculations
Calculating Income Tax
Average tax rate
Total tax paid/Income *100
Marginal tax rate
Change in Total tax paid/ Change in Income
Calculating Inflation
Inflation rate = [Price Index for Year (t) - Price Index for Year (t-1)]/ Price Index for the year before (t-1) *100
Price Index = [Cost of basket in the year considered/ Cost of basket in base year] *100
Calculating unemployment rate
Unemployment rate = (Number of Unemployed/Labour Force) *100
Labour Force= Number of employed + number of unemployed
Calculating real GDP using a price index (deflator)
RGDP =
(nominal GDP/price deflator) X 100
Nominal GDP is the value of current output measured at current prices. Real GDP measures the value of current output using base year prices.
Keynesian Multiplier
1 /(1-mpc) = K
Marginal Prosperity to consume= refers to the proportion of additional income that is spent on consumer goods and services.
Marginal Prosperity to Save
Marginal Prosperity of taxation
Calculating GDP
GDP = C (Consumption) + G (Government Spending) + I (Investment) +(X-M) (Exports - Imports)
GDP Per capita= Total GDP/ Population
GNI= GDP+ Net property income from abroad
Real GDP= Nominal GDP/ Price Deflator x 100

Qd =
Quantity Demanded
a =
the horizontal or Q-intercept
P =
Price
-b =
the gradient of the slope
Supply Functions
Qs =
c + dP
Qs =
Quantity Supplied
P =
Price
c =
Horizontal or Q-Intercept
d =
the slope
Scarcity, Choice and Oppurtunity Cost in Resource Allocation
The concept of scarcity forces society to make choices about the
What to produce
question.
Choices involve an oppurtunity cost which is the next best alternative as a result of making a choice
Relationship between PED and the slope
PED =
the slope X (P/Q)
