Could you please explain how a sector's LPP is calculated from the individual LPP's in its Industry Spending Patterns (ISP)? I'm looking at the ISP for Sector 59 for Clark County, NV (2014 data). Sum of event values is 0.51, which provides the percent of direct output spending on intermediate expenditures, if I'm not mistaken. Each sector within the ISP has an LPP. These are SAM model values and generally much less than 100%. However, the Sector 59 event SAM model value for LPP is 100%. How is the sector-wide SAM LPP 100% when the weighted average of the individual expenditures' LPPs is less than 100%? Thanks for your help.
