Change in S vs. Change in Qs Unit Three, Lesson Two Economics
Change in Quantity Supplied • This is a movement ALONG the curve resulting from a change in price • As prices change, producers will be willing to produce more or less (depending on the direction of the price change) resulting in a new point on the same graph
Change in Supply • Change in supply is when there is a shift in the entire supply curve resulting from some outside force that changes the amount of a product supplied at each given point
Change in Supply • Cost—how much the supplier must pay to make the item • Price—how much the supplier will earn when they sell the item
Change in Supply • Say you are a producer. What would cause you to produce MORE or LESS of a product, even though the price (how much you will earn when you sell the product) doesn’t change at all?
Change in Supply • Determinants of Supply—Forces that will cause the entire supply curve to shift either left or right (so producers will produce more or less, even though the price of the product has not changed)
Determinants of Supply • Factor costs—if the cost of production increases, the selling price will have to rise to cover these costs --so anything that will affect the cost of ANY of the factors of production (land, labor, capital) will shift the curve
Determinants of Supply • Technology and regulations—new production technology can lower the cost of production; regulations and requirements implemented by the government will raise the cost of production
Determinants of Supply • Expectations—future expectations of the market or industry may cause a firm to adjust its quantity supplied • The number of firms—when more firms enter the industry, more of the good can be offered at each price
Determinants of Supply • The bottom line— ANYTHING that changes how long it takes to produce or how much it costs to produce will change supply and shift the supply curve
Movement of the Supply Curve • If it costs more to make an item, will you make more or less? • LESS, so the curve shifts LEFT (just like the demand curve) • If is costs less to make an item, will you make more or less? • MORE, so the curve shifts RIGHT (just like the demand curve)
