 Now that you're familiar with the law of supply and we've seen how changes in the price of a product influence the quantity supplied Ceteris paribus, it's time to consider what happens when some of the other factors apart from price change According to our supply equation These are factors such as the cost of production technology the price of alternative products the number of other suppliers and so on to start with Let's consider the effects of a change in the cost of production PC from our previous conversations about what determines the supply of fried chicken pieces We saw that if the cost of production increases the funky chicken will tend to supply a lower quantity at the same price Looking at our supply curve at each price a lower quantity would be supplied than before and A new supply curve to the left of the original one is formed This is a leftward shift of the supply curve We can see as we did with our demand curve that any factor other than the price Which causes a change is represented by a shift of the curve as opposed to a movement along the curve So what happens to our supply curve if new technology leads to an improvement in our productivity? An increase in productivity means that at each price the funky chicken can supply more than before So the supply curve shifts to the right An increase in supply is represented by a rightward shift of the supply curve And finally looking at the price of alternative products PG What will happen to the supply curve for fried chicken pieces if the price of chicken burgers goes up? The owners of the funky chicken want to maximize profits, so they'll now try to sell more chicken burgers But what this means for fried chicken pieces is that at each price fewer pieces of fried chicken are now produced And we get a leftward shift of the supply curve for fried chicken pieces
