Economics Flashcards
Factors for Positive Demand Curve Shift
Price of substitute goods
Expectations of price increases
Consumer income and wealth
Size of the market
Factors for Negative Demand Curve Shift
The price of complementary goods
Consumer income and wealth
Group boycott
Price Elasticity
Percentage change in quantity demanded/ percentage change in price
> 1 = elastic
<1 = inelastic
=1 =unitary
Elastic
Total revenue will decline if the price is increased
Unitary
total revenue will remain the same if the price is increased
Inelastic
Total revenue will increase if the price is increased, since the percentage increase in price exceeds the decrease in demand
Income elasticity
Percentage change in quantity demanded/ percentage change in income
\+ = normal good - = inferior
Cross elasticity
Percentage change in demand for product x / percentage change in price of product y
\+= substitute -= complements
Marginal Propensity ot consume (MPC)
The percentage of the next dollar in personal disposable income that the consumer would be expected to spend
Marginal Propensity to save (MPS)
The percentage of the next dollar in personal disposable income that the computer would be expected to save
Factors Causing A Direct Relationship on the supply curve
number of producers
government subsidies
price expectations
Factors with an inverse relationship on the supply curve
Changes in production costs
Prices of other goods
Marginal cost
The increase in cost that will result from an increase in one unit of production. Only variable costs are relevant, since fixed costs won’t increase such circumstances
In the long run, all costs are…..
variable, since increasing production beyond certain levels will require increasing in capacity, caused even “fixed “ costs to rise
Return to scale
the increase in units produced (output) that results from an increase in production costs (input)
Return to scale formula
percentage increase in output/ percentage increase in input
>1 = economies of scale <1 = diseconomies of scale
Economies of scale
increased efficiency that results from producing more units of a product
Diseconomies of scale
increased inefficiencies that result from expanding production
Gross Domestic Product (GDP)
the price of all goods and services produced by a domestic economy for a year at current market prices
Real GDP
adjusted to remove the effect of price inflation in the goods and services
Gross national product (GNP)
price of all goods and services produced by labor and property supplied by the nations residents.
Difference between GDP and GNP
GNP includes income received by the nations resident from other countries for products that are a part of foreign economies
GNP excludes payments made to the residents of other countries for products that are a part of the domestic economy
