What does short-run refer too?

It refers to a period where at least one input is fixed.

100

What is a variable in long-run?

All factors of production and costs

100

What is the formula for marginal cost?

Change of total cost/change of quantity

100

What is increasing returns to scale?

Output is increasing at a faster rate than all inputs

100

What types of firms does the maximization profit apply to?

All firms

200

What is variable cost?

A cost that changes as output changes.

200

What is long-run?

All inputs can be altered no inputs are fixed plant capacity can be altered, all costs are variables

200

What is marginal cost?

The additional cost of producing one more unit of output. 
200

What is decreasing returns to scale?

Output is increasing at a slower rate than all inputs

200

What rule minimizes loss?

MR=MC rule

300

What is total cost?

The sum of fixed and variable costs.

300

What does the long-run average total cost curve look like?

A smiley face

300

What does marginal cost depend on?

Marginal production.

300

What is constant returns to scale?

Output is increasing at the same rate as all inputs

300

How does a firm earn a economic profit?

When TR>TC

400

What is fixed cost?

A cost that must be paid even when a firm's output is zero; a cost that is the same at all output levels.
400

What is economics of scale?

Long-run ATC decreases as output decreases
400

What is specialization?

When mc decreases initially.

400

What is constant returns to scale also known as?

Efficient scale

400

How does a firm break even?

When TR=TC

500

What does your change of total fixed cost divided by change of quantity find? 

Marginal cost.

500

What is diseconomies of scale?

Long-run ATC increases as output increases

500

What is diminishing returns?

When mc eventually rises.

500

What is minimum efficient scale?

helps determine the number of firms in a market

500

How does a firm earn economic loss?

When TR<TC
