answer
The period of time during which at least one of a firm's inputs is fixed
Characteristic: the firm does not have sufficient time to change the size of its plant
Characteristic: the firm does not have sufficient time to change the size of its plant
question
Long-Run
answer

question
Production
answer
Any activity that results in the conversion of resources into products that can be consumed
question
Production Function
answer
Technological relationship between inputs (resources) an outputs (how many do we product)
question
Law of diminishing returns
answer
When additional units of a variable input are added to fixed inputs after a certain point, the marginal product of the variable input declines
question
Main goal of a firm?
answer
Main goal of a firm is profit maximization where the firms wants to make as much money as possible
question
What are explicit and implicit cots?
answer
Explicit: Cost that business managers must take into account because they must be paid
Implicit: Expenses that managers don't have to pay but are a opportunity cost
Implicit: Expenses that managers don't have to pay but are a opportunity cost
question
Define total costs?
Define fixed costs?
Define variable costs?
Define fixed costs?
Define variable costs?
answer
Total costs: the sum of fixed and variable costs at each level of output
Fixed costs: do not vary with changes in output (rent, equipment lease)
Variable cost: increase with the level of output (labor, fuel, power)
Fixed costs: do not vary with changes in output (rent, equipment lease)
Variable cost: increase with the level of output (labor, fuel, power)
