ECONOMIES OF SCALE: Declining long-run average cost that occurs as a firm increases all inputs and expands its scale of production. This is graphically illustrated by a negatively-sloped long-run average cost curve and typically occurs for relatively small levels of production. Economies of scale are then overwhelmed by diseconomies 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.

The total satisfaction of wants and needs obtained from the use or consumption of a good or service. This is the cumulative amount of utility generated from consuming a good over a given time period. Total utility is most often used in consumer demand theory to indicate how much overall satisfaction someone obtains from a given activity. The primary behavioral motivation used in consumer demand theory is the goal of maximizing total utility. Total utility is also used to derive marginal utility.
