ABSTRACTION: Simplifying the complexities of the real world by ignoring (hopefully) unimportant details while doing economic analysis. Abstraction is often criticized because it's, well, it's JUST NOT REALISTIC. However, when done correctly (ignoring things that JUST DON'T MATTER), then the pursuit of knowledge is greatly enhanced by abstraction. For example, when travelling cross country along a high-speed interstate highway, a paper road map is a handy tool. It shows towns and cities along the way, the major intersections, rest stop locations, and other important points of interest. However, it ignores unimportant details. It doesn't realistically show the location of every tree, bush, or blade of grass. Why bother? This information won't enhance your road trip.

- Technological advances that improve long-run and short-run aggregate supply.
- Changes in wages and production costs that affect short-run aggregate supply.

This production decision can be analyzed directly with economic profit, by identifying the greatest difference between total revenue and total cost, or by the equality between marginal revenue and marginal cost.

Today, you are likely to spend a great deal of time waiting for visits from door-to-door solicitors hoping to buy either several magazines on computer software or a T-shirt commemorating the second moon landing. Be on the lookout for poorly written technical manuals.
