Chapter 4-5 Flashcards
Utility
Utility- the satisfaction people have from their consumption activities.
Marginal utility
Marginal utility- the additional utility gained from consuming an additional unit of a good.
The law of diminishing marginal utility
The law of diminishing marginal utility- the tendency for the additional utility gained from consuming an extra unit of a good to diminish as consumption increases beyond some point.
- An example of this would be taking 3 bites of chocolate instead of 2 can make a larger difference than taking 20 bites instead of 19.
- Overall, there will be an increase, however, it will increase at a smaller rate each time- in regards to units and subjective value.
- This is an assumption
Factors of production
- Factors of production- inputs used in the production of a good or service.
Short run
- Short run- a period of time sufficiently short for at least some of the firms factors of production to be fixed.
Long run
- Long run- a period of time of sufficient length for all the firms factors of production to become variable.
Variable factor of production
- An input whose quantity can be altered in the short run.
I.E. Unskilled labor
Fixed factor of production
An input whose quantity cannot be altered in the short run
○ I.E. Specialized machine.
Law of diminishing returns
- Increased production of a good eventually requires ever-larger increases in the variable factor when some factors of production are fixed.
- In principle observable.
Fixed cost (FC)
- The sum of all payments made to the firms fixed factors of production/ the payments that have to be made for the service of an input regardless of whether and how much production actually takes place.
Variable cost (VC)
The sum of all payments made to the variable factors of production
Total Cost
FC + VC (Fixed cost + Variable cost)
Marginal cost
The change in total cost divided by the corresponding change in output.
- MC = Change in TC / Change in Output
Average total cost (ATC)
- Total cost divided by total output.
Average variable cost (AVC)
- Variable cost divided by total output.
