But in presentation (or Slide Show) mode, it all works pretty well. As in previous chapters, “eq’m” is short for “equilibrium.” Suggestion: Briefly explain each element of the graph as it appears. (Brief is appropriate because each element will be discussed carefully in the following slides.) Note that the graph measures a nominal variable (P) on the vertical axis, and a real one (Y) on the horizontal axis. Thus, the graph highlights the breakdown of the classical dichotomy. If you are more of a micro person, then please disregard the following. Still reading? Then you must be a macro person. Excellent! Here’s something you might tell your students. This model LOOKS like the basic supply and demand model from Chapter 4, but there’s a big difference. The basic supply demand model determines the equilibrium price and quantity of a particular good, say, apples. The equilibrium price of apples is extremely important if you’re an apple grower. Ask your students to raise their hand if they plan on going into the apple-growing business. Chances are, none will raise their hands. The model of aggregate demand and supply, however, determines the equilibrium price and quantity of EVERYTHING (loosely speaking), i.e., the price level (cost of living) and real GDP (national income
