Definition
perfect inelastic
Term
What does a perfect inelastic line look like?
Definition
a straight vertical line
Term
Revenue is
Definition
P x Q
Term
Elastic zone
Definition
If you're at point B and raise your price, then you're gonna decrease your revenue
Term
unit elastic
Definition
If you're at point D and increase your price, then your revenue will be the same as before
Term
inelastic zone
Definition
If you're at point E and raise your price, you're going to increase revenue
Term
A tax will make the supply curve shift to the (right/left). Why?
Definition
left because now its more expensive to produce
Term
Gov't revenue
Definition
Tax + Qwith tax
Term
How much of the govt revenue are producers going to pay?
Definition
Below Pwihtouttax
Term
How much of the govt revenue are consumers going to pay?
Definition
Above Pwithouttax and below Pwihttax
Term
How does elasticity affect who is going to pay more tax?
Definition
If the demand curve is more inelastic, consumers will pay a higher share of the gov't revenue
Term
Price support
Definition
When the government labels a fair price and buys the excess supply
Term
subsidy
Definition
When producers sell at market prices and pays the producer S per unit sold

A measure of the price level calculated as the ration of nominal GDP to real gdp times 100.
Term
What does the GDP deflator tell us?
Definition
The rise in nominal GDP that is attributable to a rise in prices rather than a rise in the quantities produced
Term
Real GDP =
Definition
Nominal GDP/GDP deflator x 100
Term
GDP Deflator =
Definition
Nominal over real x 100
Term

Term
shift or the curve
Definition
caused by anything else besides price changes.
Term
elasticity
Definition
measure how sensitive is the demand (supply) to price changes.
Term
Supply-side economics
Definition
1) Taxes, government regulation, and government spending are the three tools of supply-side economic policy. Supply-siders believe that lower tax rates, less government regulation, and less government spending would stimulate economic growth. As well, lower tax rates would provide stronger incentives to work and produce, by increasing after-tax wages and profits. Less government regulation would reduce production costs, spurring profits and production. They also believe that government spending crowds out private sector investment by driving up the interest rate and by providing private investors with more competition in the securities market.
Term
Inertial Inflation
Definition
prices keep increasing because wage contracts are indexed by inflation. That way, when price increase so wages must also increase, but then the cost to produce increase and prices increase again. Since the wages will increase, the process is going to repeat all over again infinitely.
Term
Negative interest rate
Definition
If nominal interest rate is lower than inflation, there will be negative interest rate (nominal interest = real interest + inflation)
