The problem is that I don’t know how to calculate them when I, P, and Q are unknowns. Or are the elasticity’s simply just the coefficients of P an I? I would really appreciate if someone could help me out here. Demand equation: Q = a – bP + cI + dT Q = 514.2669 – 242.971P + 1.224164I + 2.931228T Elasticity formulas: Price elasticity of demand: b(P/Q) Income elasticity: c(I/Q) Q = Demand estimation P = Price I = Income T = Temperature
