# Cost curves

### See how cost curves respond to:

See how cost curves respond to:

higher or lower fixed cost

an output-invariant marginal cost component

and an economies of scale parameter.

[Hint: set F=0 for long-run cost curves: AC=SAC=AVC]

### Try testing the look of different cost scenarios:

Try testing the look of different cost scenarios:

Enter any total cost function you'd like to see represented (notation assumes short-run, but MC & AC graphs apply in LR as well)

Notes:

* If you are thinking of a*long-run*scenario, so none of the costs are sunk, simply ignore curves AVC and AFC, and think of SAC as AC

**The calculations built into the graph assume that the cost function you are entering applies for all quantities, starting from q=0. In

*some*short run scenarios this assumption is broken, so the graphs produced won't be entirely helpful. (But, you can look under the hood and tinker! Maybe change a limit on an integral...)
