or which lags are the t statistics less than two? (iii) what is the estimated long-run propensity? is it much different than one? explain what the lrp tells us in this example. (iv) what regression would you run to obtain the standard error of the lrp directly? (v) how would you test the joint significance of six more lags of gwage? what would be the dfs in the f distribution? (be careful here; you lose six more observations.)
