The Aggregate Production Function lardbucket

In many appliions, we want to understand how the aggregate production function responds to variations in the technology or other inputs. This is illustrated in Figure 16.9. An increase in, say, technology means that for a given level of the capital stock, more output is produced: the production function shifts upward as technology increases.

production process of aggregates

There are two basic types of cement production processes and a number of different kiln types. Cement production is either "wet" or "dry" depending on the water content of the material feedstock. The wet process was the original rotary kiln process developed at a time when material handing of slurries was more developed than those of dry powders.
