Table I-7-2. Colorado River Basin: National Efficiency Results (CGE) (Critical Habitat Only) (Percentage Deviation from Without Fish Scenario) Scenario Al Scenario AZ Scenario Bl Scenario B2 Variable vs Without Fish vs Without Fish vs Without Flsh vs Without Fish Real Gross Regional Product 0.0009% 0.0011% -0.0008% 0.0000% Employment 0.001590 0.001590 , -0.0010°/0 0.00030/0 Earnings 0.001890 0.0018% -0.0002% 0.000190 Gov't Revenue 0.000790 0.000990 -0.001690 0.000090 Notes: Scenario Al: There exists sufficient underutilized capacity in the construction and capital equipment sectors (within the Basin or elsewhere in the national economy) that all additions to thermal electric capacity are a net positive addition to the level of national economic activity. The recreazion resources within the Basin are unique and the loss of these recreation opportunities cannot be replaced within the U.S. economy. Scenario Bl: There is no underutilized capacity in the construction and capital equipment sectors (within the Basin or elsewhere in the nazional economy) and all additions to thermal electric capacity within the Basin are constructed with resources that must be displaced from elsewhere in the national economy. Thus, there is no net positive economic impact from the expenditure on thermal expansion. The recreation resources within the Basin are unique and the loss of these recreation opportunities cannot be replaced within the U.S. economy. Scenario A2: There exists sufficient underutilized capacity in the construction and capital equipment sectors (within the Basin or elsewhere in the national economy) that all additions to thermal electric capacity are a net positive addition to the level of national economic activity. This is the same assumption that was made in Al. However, in this scenario, the recreation resources within the Basin are not unique. In particular, it is assumed that foregone recreation opportunities in the Basin can be completely offset through opportunities elsewhere in the U.S. economy. Thus, there are no negative impacts in the recreazion sector. Scenario B2: There is no underutilized capacity in the construction and- capital equipment sectors (within the Basin or elsewhere in the national economy) and all additions to thermal electric capacity within the Basin are constructed with resources that must be displaced from elsewhere in the nazional economy. Thus, there is no net positive impact from this expenditure on thermal expansion. However, in this scenario, the recreation resources within the Basin are not unique. In particular, it is assumed that foregone recreation opportunities in the Basin can be completely offset through opportunities elsewhere in the U.S. economy. Thus, there are no negative impacts in the recreation sector. I-45
