P - Production Lag, if it is hard to increase the amount of production. PES is Inelastic.
What does SSS stand for in PSSST?
Stock - How much stock is available on hand.
Spare Capacity - More spare capacity the more elastic as can respond faster to change.
Substitutability of F of P, if you can substitute what F of P are producing fast then PES is Elastic.
What does T stand for in PSSST?
Time lag - Short run producers may find it hard to change F of P to produce more, however Long run they may be fine with it.
