processed. The aggregate production approach is predicated on the existence of an aggregate unit of production, such as the \average" item, or in terms of weight, volume, production time, or dollar value. Plans are then based on aggregate demand for one or more aggregate items. Once the aggregate production plan is generated, constraints are ...

The Aggregate Production Function - lardbucket

The aggregate production function describes how total real gross domestic product (real GDP) in an economy depends on available inputs. Aggregate output (real GDP) depends on the following: Physical capital—machines, production facilities, and so forth that are used in production. Labor—the number of hours that are worked in the entire economy.
