3 15 points In accordance with the dual-control approach, suppose New Mexico's NOx abatement standard for existing sources is 5 units (AE) and the EPA's standard for new sources is 12 units (AN). If the two types of sources face the following MCA functions, where each MCA is in thousands of dollars, what economic criterion is violated? Show how you know. For existing sources, MCAE = I .8AE and for new sources, MCAN = 1.2AN .
