What is the cost-push theory of inflation?

Cost-Push inflation is where prices rise due to, such things as raw materials and wages going up. The number one way this can occur is the change of the Cost of Production (C.O.P). Specifically the change is a rising C.O.P. For this phenomenon to begin there must be a constant demand for said product. Now, Cost-Push Inflation can be unexpected or foreseen beforehand. I've already stated what happens when it is foreseen. For it to be unexpected one of these must take place: floods, tornadoes, earthquakes, etc. Those are commonly referred to as Natural Disasters but, I'm sure everyone knows that.

I will stop right here seeing as though this is a lot of information.

I hope this helps!!
