Economics Flashcards
Supply
Supply for an item is defined as a schedule showing the amount of that item that sellers can and will supply at various price levels during a given period of time
Demand
Demand for an item is the schedule of the amount of that item that buyers can and will purchase at various price levels during given period of time.
The intersection of the supply and demand curves is…
the equilibrium or market-clearing price
Demand Elasticity
Ed = (%∆ in Qd/%∆ in P)
If Ed>1, demand is…
Elastic
If Ed<1, the demand is…
Inelastic
Ed = 1 is…
called unit elasticity
Demand for an item tends to be _______ at higer prices and _______ at lower prices
elastic; inelastic
If Ed > 1, a price decrease will ______ total revenue
increase
If Ed < 1, a price decrease will ______ total revenue
decrease
The main factor affecting supply elasticity is…
time
The % increase in sales needed to maintain the same revenue while decreaseing the price is…
Price Decrease %/(1-(Price Decrease %))
The % increase in sales required to increase revenue and decrease prices
[(1+Sales Increase) - (1-Price Decrease)]/[1-Price Decrease]
Normal Profit
The cost of obtaining and retaining entreprenurial ability
Economic Profit
Sales - Raw Materials - Operating Expenses - Normal Profit
Firms earning losses will __________________ in an attempt to earn economic profits where they are available
reallocate their resources
As the ______ system allocates resources toward _________ industries and away from __________ industries, the economy as a whole reaches general ___________.
price; expanding; declining; equillibrium
Short Run
Period over which fixed costs cannot be changed although they can be used in different ways. In the short run, resources that can be changed are called variable costs.
Law of Diminishing Returns
The more variable resources are combined with fixed resources, there will be a point beyond which the marginal output obtained by adding additional variable resources will decline.
Average Total Cost (ATC)
ATC = AFC + AVC
Average Fixed Class (AFC)
Total fixed costs / output
Marginal Cost (MC)
∆Cost / ∆Output
If MC < AVC, AVC will ______________ and once MC > AVC, _____________.
continue to fall; will begin to rise
The MC and AVC intersect at…
the minimum point of the AVC curve.
In the long run, all costs are ____________.
variable
After an intial decline in ATC due to ____________________, the curve reaches a minimum point and then begins to rise as _________________ begin to have an effect.
economies of scale; diseconomies of scale
The smallest level of output at which a firm can achieve minimum ATC is called _____________________.
Minimum Efficient Scale (MES)
When diseconomies of scale are encountered quickly, MES will occur ar _______ levels or output. When economies of scale are extensive, MES will occur at ________ levels of output.
lower; higher
Economies of Scope
Synergies created from vertical integration
GNP
Measures the total value of all goods and sercives produced by a national economy. Includes goods and services produces by domesically based firms opperating abroad.
GDP
The output of goods and services produced domestically without regard to the origin of the producer
