#ono!o$istic Co!etition

!$n$p$listic c$mpetiti$n is a ar(et structure in )hich -arriers toentr' are $o) and an' firs co!ete -' se$$in& sii$ar, -ut notidentica$, !roducts.

The (e' feature here is that the !roducts that ono!o$istica$$'co!etiti"e firs se$$ are differentiated fro one another in soe)a'.

Example: Starbucks sells coffee, and competes in the coffee market

against other firms selling coffee.

But Starbucks’ coffee is not identical to the coffee that other firms sell.
