What is “free market” economics?
A system in which the government stands aside as far as possible

The unobservable market force that helps the demand and supply of goods in a free market to reach equilibrium automatically
What is Keynesian Economics?
Keynesian economic theory is a macroeconomic theory that advocates for increased government spending and lower taxes to stimulate demand.
Spending + Lower Tax = Demand Growth
the classical school of thought was failing to rescue economies from the Great Depression of the 1930s,
What is marginal propensity to consume?
the proportion of an increase in income that gets spent instead of saved
MPS = 1 - MPC
What is the formula for Marginal Propensity to Consume?
Change in Consumption / Change in Income
What is Say’s law?
to have the means to buy, a buyer must first have produced something to sell. Thus, the source of demand is production
Say’s Law implies that production is the key to economic growth and prosperity and the government policy should encourage (but not control) production rather than promoting consumption.
What is the formula to calculate the multiplier effect for MPC?
k=1/(1-MPC)
What is consumption?
Expenditure by private households
What is the formula for consumption function?
a+cY
Where a = minimum consumption to survive
c = MPC
Y = Disposable Income
What is aggregate demand?
The total demand for final goods and services in an economy at a given time.
How is aggregate demand calculated?
Aggregate demand = C + I + G + (X – M)
Consumer
Investment
Government
Export - Import
What does credit creation do to a country’s money supply?
Increases it and in turn should:
1) Lower Interest Rates
2) Generate More investment
3) Stimulate Spending
What is the reserve requirement?
The amount of capital a bank is required to hold in reserve.
Central banks can tighten these requirements to restrict the money supply.
financial institutions will have to be more selective in their lending, as they have effectively less to lend.
What does the Phillips curve say about Unemployment and Wage Inflation?
Low unemployment = higher wage growth
Higher unemployment = lower wage growth
Companies must pay more to attract talent when unemployment is low. This pressure subsides when unemployment increases.
