Section 1; REMI overview explains what the REMI Tax-PI MR model is, and how and why it is used. Section 2; Modeling LIFT using REMI details how JLARC staff set up the Tax-PI MR program and modeled scenarios to reflect the range of possible results. Section 3; Detailed assumptions and results show the employment changes resulting from each scenario at the county level.
