AD CURVE: The aggregate demand curve, which is a graphical representation of the relation between aggregate expenditures on real production and the price level, holding all ceteris paribus aggregate demand determinants constant. The aggregate demand, or AD, curve is one side of the graphical presentation of the aggregate market. The other side is occupied by the aggregate supply curve (which is actually two curves, the long-run aggregate supply curve and the short-run aggregate supply curve). The negative slope of the aggregate demand curve captures the inverse relation between aggregate expenditures on real production and the price level. This negative slope is attributable to the interest-rate effect, real-balance effect, and net-export effect.

Circular Flow
This lesson introduces the circular flow model of the macroeconomy. The circular flow is a simple model based on the buying and selling relation between the household and business sectors which occurs through the product and factor markets. As a bonus, we complicate the simply circular flow model, by including the government and foreign sectors, and the financial markets. This lesson introduces several important macroeconomic concept, but more importantly, provides a useful model for interpreting macroeconomic activity. - In the first unit, we get an introduction to the simplest circular flow model that includes the household and business sectors and the product and factor markets.
- The second unit builds on the simple model by introducing the financial markets, which highlights the importance of household saving and business investment.
- The circular flow is expanding further in the third unit, with the introduction of the government sector, which highlights how taxes are diverted away from the household sector.
- The fourth unit adds one more sector to the circular flow model, the foreign sector, which illustrates the roles played exports and imports.
- The fifth unit wraps up this lesson by showing how several key measures of production and income revealed in the analysis of gross domestic production related to the circular flow.

PLASTIC MONEY A slang phrase for credit cards, especially when such cards used to make purchases. The "plastic" portion of this term refers to the plastic construction of credit cards, as opposed to paper and metal of currency. The "money" portion is an erroneous reference to credit cards as a form of money, which they are not. Although credit cards do facilitate transactions, because they are a liability rather than an asset, they are not money and not part of the economy's money supply.
