model with lagged explanatory variables? Dependent variable (Y) is the total return on the stock market index over a future period but the explanatory variable (X) is the current dividend-price ratio. + =α+β + +t h t t h Y X e , h is forecast horizon Yt+h is calculated using the returns Rt+1, Rt+2,.., Rt+h. Equivalently: t =α+β − +Y X e t h t. variables. The essential nature of the problem can be illustrated via a simple model which includes only a lagged dependent variable and which has no other explanatory variables.

With time series new issues arise: 1 . One variable can influence another with a time lag. 2. If difference estimator for the lagged dependent variable is also biased dependent variable, by using the appropriate lags as instruments of the variables . In. Lagged Dependent Variables. The Durbin-Watson tests are not valid when the lagged dependent variable is used in the regression model. In this case, the Durbin with a lagged dependent variable and period and unit dummies (the de facto Beck-Katz standard).

Blundell and Bond (1998) derived a condition under which it is possible to use an additional set of moment conditions. These additional moment conditions can be used to improve the small sample performance of the Arellano–Bond estimator. Although the coefficent of interest variable is significant, the first lag of dependent variable is not siginificant. I also try deeper lags but no one is significant.
