TOTAL PRODUCT AND AVERAGE PRODUCT: A graphical connection between total product curve and average product curve stating that the slope of a line between the origin and any point on the total product curve is equal to the average product. Imagine a ray shooting out of the origin and hitting the total product curve. As this ray hits each point on the curve, remaining anchored at the origin, the slope of the ray changes. And the slope of this ray is average product.

- It's quite useful to identify or measure the degree of concentration in an oligopoly market. This is generally accomplished in one of three ways.
- Market Share: The simplest measure of concentration is the share of the market held by one or more firms in the industry.
- Concentration Ratio: This measure of concentration combines the market shares for the largest number of firms in an industry to indicate the degree of market concentration.
- Herfindahl Index: The Herfindahl index includes the market shares of all firms in the market.
- Consideration and analysis of concentration using either of these three measures is really only relevant for oligopoly.

CREATIVE DESTRUCTION A fundamental process of capitalism, popularized by Joseph Schumpeter, in which the benefits of growth and prosperity induced by innovations also result in the costs of disrupting existing means of production. The creation of new activity involves the destruction of existing activity. This notion attributes business-cycle instability to innovations, including both the expansionary rise of prosperity, as well as a contractionary decline. Creative destruction is based on the idea that rather than tending toward equilibrium, the economy is largely in flux. A key question is one of cause and effect. Does innovation cause destruction or does destruction induce innovation?
