With the new data from Exercise 1, replicate models (i) and (ii) of Section 4.1.1. Run different regression models by adding two more lags for price and interest rate movements. Compare your results with models (i) and model (ii). Is a uni¬variate information set more valuable than a multivariate information set to explain housing prices? Are the new models better than models (i) and (ii) at explaining price growth?
