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.

FACTOR DEMAND ELASTICITY The elasticity of a factor demand curve is affected by four items: (1) the price elasticity of demand for the good produced, (2) the production function technology and elasticity of marginal physical product, (3) the ease of factor substitutability, and (4) the share of the factor's cost relative to total cost. Changes in any of these four items cause the price elasticity of factor demand to change. In other words, the quantity of factor services demanded becomes more or less sensitive to changes in the factor price.
