Divisibility: One of four characteristics that enables an asset to better function as money. The other three are durability, transportablity, and non-counterfeitability. This characteristic means that the item used as money can be easily divided into small increments so that it can match commodity values more precisely.
Diseconomies of scale: Increasing long-run average cost that occurs as a firm increases all inputs and expands its scale of production. This is graphically illustrated by a positively-sloped long-run average cost curve and typically occurs for relatively large levels of production. Diseconomies of scale overwhelm by economies of scale for relatively large production levels. Together, economies of scale and diseconomies of scale cause the long-run average cost curve to be U-shaped.
Duopsony: A special type of oligopsony market structure dominated by exactly two large buyers controlling the buying-side of a market. Duopsony is the buying-side counter to the duopoly selling-side market structure. As market structures go, this is perhaps the most obscure one around.
Currency depreciation: The declining value of one currency, in terms of its ability to purchase goods and services. This is most often seen as a change in the exchange rate of the currency for the currencies of other nations.
Consumption line derivation: A consumption line, a graphical depiction of the relation between household sector consumption and income, can be derived from a simple consumption schedule, a table or chart showing the relation between household sector consumption and income. This is easily accomplished by plotting the consumption-income pairs from the schedule as points in a diagram that measures consumption on the vertical axis and income on the horizontal axis, then connection the points with a line. The consumption line can also be derived directly by plotting the consumption function using slope and intercept values.
Saving line derivation: A saving line, a graphical depiction of the relation between household sector saving and income, can be derived from the consumption line. The saving line can also be derived by plotting the saving-income information from a saving schedule or using the slope and intercept values of the saving function. However, derivation from the consumption line emphasis the connection between consumption and income--that the household sector uses a portion of income for consumption and a portion for saving.
