Consider the following system of equations: System 1: System 2: Yt Bo + BiXt + B₂St + u₁t Zt ao + a₁X + Uzt Y₂ = Zt W₁ = ao + a₂Ut + a₂ Pt + U₁t Pt Bo + B₂W + B₂Rt + B3Mt + Uzt a) Use the order conditions to determine the identification of each equation in each system (that is, whether the equations are under-identified, over-identified or exactly identified). [5 marks] b) Carefully derive the conditions under which the OLS estimate of a₁ from the Z, equation in System 1 would be consistent. [12 marks] c) A researcher intends on estimating each equation of System 2 using OLS. Carefully discuss the consequences of using OLS to estimate each equation of system 2. Describe an alternative method.
