ACCOUNTING PROFIT: The difference between a business's revenue and it's accounting expenses. This is the profit that's listed on a company's balance sheet, appears periodically in the financial sector of the newspaper, and is reported to the Internal Revenue Service for tax purposes. It frequently has little relationship to a company's economic profit because of the difference between accounting expense and the opportunity cost of production. Some accounting expense is not an opportunity cost and some opportunity cost is does not show up as an accounting expenses.

Market
In this lesson, we'll see how buyers (discussed in the demand lesson) come together with sellers (discussed in the supply lesson) to exchange commodities using a market. More precisely, this lesson develops an abstract market model, or market analysis, that we can use to explain and understand a wide range of real world exchanges. - This lesson begins with an overview of the basic exchange process underlying markets, including the notion of equilibrium, the roles played by price and quantity, and the importance of competition.
- In the second unit we work through a simple market analysis using demand and supply schedules, highlight both equilibrium and disequilibrium conditions.
- The third unit then carefully examines the notion of market equilibrium using demand and supply curves, which generates the widely used graphical model of the market.
- Moving onto the fourth unit, we use the graphical market model to investigate the automatic market responses to shortages and surpluses.
- The lesson concludes in the fifth unit by considering the relation between market exchanges and efficiency.

Hypothesis verification, model construction, and comparative static analysis are not possible without abstraction.
