3) Suppose you estimate the consumption function Y = a₁ + ax + u₁ And the savings function Z₁ =B₁ + B₂X+U₂ where Y = consumption, Z = savings, X = income, and X = Y + Z, that is, income is equal to consumption plus savings. a) What is the relationship, if any, between a, and B,? Show your calculations. b) Will the residual sum of squares, RSS, be the same for the two models? Explain. c) Can you compare the R² terms of the two models? Why or why not?
