and Suppose that we then estimated the following pair of regressions: [1] f = 5000 + 50t + 0.1s, (1000) (32) (0.02) - - [2] Af = 50.5(f-1 f-1) + 0.70s 0.2As-1 + 0.1Aft-1 (4.3) (0.1) (0.2) (0.34) (0.7) where numbers in () are the standard errors of the estimated coefficients. f represents the FTSE100 index and s represents the S&P 500 index. The residuals from regression (2) do not exhibit serial correlation or heteroskedasticity. Given these results, what can be said about the relationship between the two indices?
