The typical approach to teaching supply-and-demand analysis in an introductory economics course involves building the foundation of both sides of the market (e.g., buyers and sellers) as they interact with each other through a transaction. This is extended to include the possibility that the supply and/or demand curves can shift due to a change in some factor(s). For example, a demand curve might increase if folks develop a stronger preference for the product across time. Alternatively, a supply curve might decrease if the costs of production grow across time. These distinct changes have predictable effects on the price of the product and quantity purchased. While this is a useful framework for discussing how different factors within markets will impact transactions, the methodology falls short when students are presented instead with a change in the price of the product, the quantity purchased, or both. While some factors changed, these may be hidden from the presentation for a variety of reasons. I thus propose a new type of analysis called 鈥淭he Equilibrium Crosshairs.鈥� By applying the notation of a compass to an updated framework, this approach encompasses the original method, and thus offers students a more robust analytical framework. To further explore the benefits (costs) of this framework over the original, this project has four distinct parts. First, we fully develop the crosshairs under an exhaustive list of circumstances. Second, we create a simple set of analytical exercises to be used as the basis of an experiment on a convenience sample of students in introductory economics courses. Third, (with IRB guidance, of course), we run said experiment on said convenience sample to assess the effectiveness of the crosshairs. Fourth, we maintain a record of the entire process to generate a paper for publication in a general interest teaching economics journal.
