I am updating an analysis that used 2010 IMPLAN data with 2012 data for the San Francisco Bay area region (9 counties) and noticed a significant decline in the Induced multipliers across the majority of industries. I have attached a spreadsheet to illustrate some examples. For instance the induced multiplier for sector 332 "Transp. by Air" decreased from .43 to .24, a 44% drop. This and other examples are contained on the tab "2010 vs. 2012." One thought I had was that employee household spending on web-based purchases out of state has increased which means that less HH spending is occurring locally. Do you have any other plausible explanations as to why there was such a large drop in the Induced multipliers? Is this related at all to changes in Proprietors Income? I included two additional tabs "Output Multipliers" that compares the 2010 and 2012 Induced multipliers for this region as well as "Industry Detail" for both 2010 and 2012 (same region). Thanks Adam
