In many applications, 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.

Fine aggregates are essentially any natural sand particles won from the land through the mining process. Fine aggregates consist of natural sand or any crushed stone particles that are ¼" or smaller.This product is often referred to as 1/4'" minus as it refers to the size, or grading, of this particular aggregate.
