The model of consumption and taxation we developed in class assumes no autonomous taxation (that is, all taxes directly depend on income). Derive an IS curve equation for an economy where taxes are described by =0+1y, where 0 is the level of autonomous taxes. (Note: do not just substitute 0+1y for . The key to this problem is thinking about what the equations mean and setting it up properly.)
