Session Overview
In this lecture, we continue to learn about competition, and its implications for the supply curve for different goods. We can use this to construct the market supply curve from firms' supply curves. Now we have all the ingredients for fully understanding the basic supply and demand diagrams that launched our study of economics. In this lecture, we will learn about the factors that influence a firm's shutdown decision. Image courtesy of johnthurm on Flickr. |
Keywords: Shutdown decisions; market supply curves; short-run market equilibrium; long-run market equilibrium.
