Calculate unweighted PPPs for the 3 sub-headings by group of countries

Basic Heading (BH) breakdown into 3 sub-headings: Materials, Labor, Equipment

Aggregate the PPPs for the 3 subheadings using the Resource Mixes to obtain weighted PPPs for the 3 BHs

Combine the adjusted BH PPPs using expenditures on the BHs as weights to obtain overall PPPs for construction

Adjust the 3 BH PPPs for mark ups, professional fees and end-user taxes
