KILLER APPLICATION: A computer program that is so incredibly useful, popular, and profitable that the company responsible for development achieves enormous growth in a relatively short time period. Several computer companies developed killer applications during the 1980s and 1990s, which contributed greatly to the computer revolution. The Lotus 1-2-3 spreadsheet program was among the first, and perhaps most noted, killer applications. This program motivated millions of businesses and consumers in the early 1980ds to purchase personal computers.

Economic Science
In this lesson you'll see why and how the scientific method is a process of discovery. You'll see that it's a process of building theories to explain the workings of the world (the economy) by proposing then testing hypotheses. The five units making up this lesson will guide you through the basics of the scientific method and how it's used in the study of economics. - The first unit, The Method, introduces the scientific method, especially its' four key components -- theories, principles, hypothesis, and data.
- The second unit, Theory, then takes a closer look at theories, including the central role played by abstraction.
- In the third unit, Verification, we focus on the process of verification -- how and why hypothesized relationships about the workings of the economy are compared with actual data.
- We then turn out attention in the fourth unit, Science and Practice, to a simple example of how the scientific method is used to test a hypothesized relation between course grades and where students are seated in a classroom.
- The fifth and final unit in this lesson, Cause and Effect, examines the role that cause and effect plays in the scientific method and economic science.

PERFECT COMPETITION, REALISM Perfect competition is an idealized market structure that does NOT exist in the real world. While some real world industries might come relatively close to one or two of the four key characteristics of perfect competition, none matches all four sufficiently that they can be declared PERFECTLY competitively. Some industries come close on the large number of small firms and the identical product characteristics. A few industries have relatively good, although not perfect, information about prices and technology. However, almost all industries fall far short of the perfect mobility characteristics.

[What's This?]
Today, you are likely to spend a great deal of time browsing about a thrift store looking to buy either an ink cartridge for your printer or a rechargeable battery for your camera. Be on the lookout for telephone calls from long-lost relatives.
