No commodity output for 495, 496, 497, 498 or 499

[b]Question:[/b]For some public sectors (496, 497, 499) in San Diego 2006 data, we get zeros in \"industry commodity production\" column on commodity summary table while we get substantial numbers ($200-990 million) in \"industry outlay\" column on industry summary table. How should we interpret this big discrepancy? [b]Answer:[/b] Government enterprise sectors are industry only, they do not produce a unique commodity - one not already produced by a private sector. For example a Federal utility (eg, tva,bpa) produces power (commodity 30). That is, the industry output of 495 Federal Electric Utilities is commodity 30 Power. This becomes apparent when you look at the make matrix for these industries and note which commodities these industries produce.
