question
Shift the budget line out(up and to the right)
answer
When parameters like income(M) and price(P1 and P2) change the budget line usually changes as well. If a consumer's income increase while prices remain unchanged this will

question
Life saving medicine
answer
Which of the following good is MOST LIKELY to have very inelastic demand?
question
A function that gives the maximum amount of output from a given amount of inputs
answer
Firms often have many ways to produce a given level of output. However, since the inputs are costly, they are usually concerned with producing the most output they can. Therefore a firm's production function y=f(x1,x2) is
question
Fixed Proportions
answer
A firm makes railroad track using metal railroads and wooden planks. To make each segment of railroad track, the firm must use exactly two metal rails and ten wooden planks. Any more of either resources does not help. What kind of technology is the firm using?
question
If we increase the amount of one input being used, we should be able to produce at least as much output as before.
answer
What does it mean for Technology to be Monotonic?
question
In the short-run the firm has some inputs that are fixed and cannot be changed.
answer
The difference between short-run and long-run is that
question
Gives the lowest possible cost of producing given output y
answer
A firm's cost function
question
Increase as output increases
answer
If a firm's production function has decreasing returns to scale DRTS then its average cost(AC) will
question
The MC curve intersects both AC and AVC curves at their lowest points
answer
If we graph Marginal Cost curve(MC), the Average Variable Cost curve(AVC), and the Average Cost curve(AC) on the same graph we will see that
question
That the firm will only set its output, not its price.
answer
When a firm is in Perfect Competition we, know
question
Only the part of the MC curve above the AVC curve
answer
The supply curve of a firm in a Perfectly Competitive market is
question
The sum of all individual demands in a market
answer
Market Demand is

question
A tax levied per unit bought or sold
answer
What is a Quantity Tax?
question
There is no difference: the end result is exactly the same
answer
When a tax is imposed on a market, it is usually imposed on either the consumers or on the producers. What effect does imposing the tax on the producers have relative to imposing it on the consumers?
question
Whoever has less responsiveness to changes in price
answer
When a tax is imposed on a market, who bears more of the tax burden between producers and consumers?
question
It is completely passed along to the consumers
answer
If supply is Perfectly Elastic, how is the tax burden distributed?
question
The lost value to society due to the reduction in sales of a good because of a tax
answer
What is the Dead Weight Loss of a tax?
question
