To Estimate Dynamic Causal Effects, Your Textbook Presents the Distributed

Essay

To estimate dynamic causal effects, your textbook presents the distributed lag regression model, the autoregressive distributed lag model, and a quasi-difference representation of the distributed lag model with autoregressive errors. Using a simple example, such as a distributed lag model with only the current and past value of X and an AR(1)model for the error term, discuss how these models are related. In each case suggest estimation methods and evaluate the relative merit in using one rather than the other.
