There are many things adversities that cause the rise and fall of supply and demand. For example, if Crab prices rises, a Red Lobster sales price will increase also on crabs this will cause the demand of crabs to decrease this is price of input. When crab production become abundant again causing more crabs to over flow Red Lobster the market price on crabs will decreases this creates a good technological change. When Red Lobster menu changes by adding a variety of plates that do not include crabs when the crab prices are high they focuses on selling the other entrees available this is known as prices of substitutes in production. Another way change affects supply and demand is by the number of firms or business selling same or similar products in the market. These new business bring more competition and prices may vary depending on the supply in demand.

The price of gas is another Market this is very unstable and has no balance of supply and demand. The changes in prices and quantity affect the equilibrium in positive and negative ways. There can be talks of a hurricane in Cuba and it will cause the price of gas to go up 50 cents. Holidays or warm weather cause the price of gas to sky rocket. There seem to be no one with a hand on who control these prices.
