Labor Productivity and Economic Growth Macroeconomics

We can formalize these ideas by introducing the concept of the the aggregate production function A production function is the process of turning economic inputs like labor machinery and raw materials into outputs like goods and services used by consumersA microeconomic production function describes the relation between the inputs and outputs of a firm or perhaps an industry...

Moisture Content

Since aggregates are porous to some extent they can absorb moisture Generally this is not a concern for HMA because the aggregate is dried before HMA production However this is a concern for PCC because aggregate is generally not dried and therefore the aggregate moisture content will affect the water content and thus the water-cement ratio also of the produced PCC and the water content...

The Aggregate Production Function

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 169An 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 increas...
