RESOURCE PRICE, AGGREGATE SUPPLY DETERMINANT: One of three categories of aggregate supply determinants assumed constant when the aggregate supply curve is constructed, and which shifts the aggregate supply curve when it changes. An increase in a resource price causes a decrease (leftward shift) of the short-run aggregate supply curve. A decrease in a resource price causes an increase (rightward shift) of the short-run aggregate supply curve. The other two categories of aggregate supply determinants are resource quantity and resource quality. Specific determinants falling into this general category include wages and energy prices. Anything affecting the prices paid for the use of labor, capital, land, and entrepreneurship is also included.

DISSAVING:

Another term for negative saving the occurs during a given period of time in which consumption expenditures exceed income. Dissaving is only possible by spending past or future income on current consumption. That is, using income saved from previous periods or borrowing income to be earned in future periods. Saving is generally illustrated by the vertical difference when between the consumption line and the 45-degree line. Dissaving results when the 45-degree line lies above the consumption line.
Dissaving results when consumption is greater than income and is essentially the opposite of saving. Saving takes place when consumption is less than income. This unspent income is directed toward the financial markets (where it is then borrowed to finance other expenditures). For those doing the saving, this results in an increase in financial assets (that is, deposits in savings accounts) or a decrease in financial liabilities (that is, paying off loans).

Dissaving occurs when funds are directed away from financial markets and used to pay for consumption expenditures in excess of income. For those doing the spending, this results in a decrease in financial assets (that is, withdrawals from savings accounts) or an increase in financial liabilities (that is, making new loans). In other words, current spending is financed with either past income (savings accounts) or future income (loans).

One easy way to identify dissaving is directly through the saving line, such as the green line, labeled S, in the top panel of the exhibit to the right. This saving line is positively sloped, ranging from -$1 trillion if income is zero, up to $1.5 trillion if income is $10 trillion. At $4 trillion of income saving equals zero as the saving line goes from negative to positive and crosses the horizontal axis.

Saving (that is, positive saving) occurs for income levels exceeding $4 trillion. Over this range the saving line lies above the horizontal axis. In contrast, dissaving (that is, negative saving) takes place for income levels less than $4 trillion. Over this range the saving line lies below the horizontal axis.

Another way to illustrate dissaving is through the consumption line, such as the red line, labeled C, in the bottom panel of the exhibit to the right. For reference, a black 45-degree line is also presented. The 45-degree line indicates all points in the exhibit in which consumption measured on the vertical axis is exactly equal to income measured on the horizontal axis. Because saving is the difference between income and consumption, this line also indicates all points in which saving is zero. Neither saving nor dissaving takes place on the 45-degree line.

Best of all, this line can be used to identify saving, the difference between income and consumption. If the 45-degree line lies above the consumption line, such as what exists for income in excess of $4 trillion, then saving is positive. If the 45-degree line lies below the consumption line, which occurs for incomes less than $4 trillion, then saving is negative... and dissaving occurs.

For the most part, dissaving in the macroeconomy is a theoretical extrapolation of the consumption-saving-income relation that occurs if income is low enough. Such a situation seldom arises.

Individuals, however, frequently encounter dissaving. A typical consumer, such as Pollyanna Pumpernickel, who lives her life from paycheck to paycheck, is a car repair, hospital stay, or frozen water pipe away from dissaving. Should an unexpected expense arise, then her annual consumption expenditures are bound to exceed her annual income. The extra expense might be paid for out of previously accumulated savings (meager though they may be) or by charging up the balance on her credit cards (as maxed out as they may be). In either event, dissaving occurs.
