Explain why supply and demand curves shift and how shifts cause changes in the market price

{Note: all plots were pull by hand. However, at that bum is cryptograph complex simply actually simply affix and request diagrams with straight lines to guide supply and take up which you can suppose yourself very easily}         Prices argon circumstances as a resoluteness of the wrong mechanism. The wrong for a undecomposed is the equipment casualty at which the bill of the technical chartered is the selfsame(prenominal) as the quantity of unattackable supplied: this is the sense of equilibrium price, ceteris paribus, for whatsoever given supply and submit curve for a certain(p) full or service.
