The Aggregate Production Function - lardbucket

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.
