We can obtain the 2SLS estimator in two steps as we have seen However the standard errors reported in the second stage regression are incorrect Stata does not recognize that it is a second stage of a two stage process, it fails to take into account the uncertainty in the rst stage estimation. This step involves asking the right questions to ourselves. Policy-makers find this data to be very insightful and depend on these inferences to form very important policies and decisions. Is the quantity demanded of a certain commodity inversely related to its price? The methodology of econometrics is fairly straightforward. In the third stage, statistical procedures are used to forecast unknown points in the statistical model. For example, it is possible to study the effects of political campaign expenditures on voting outcomes. On the other hand, econometrics is the subset of economics that utilize statistical tools to examine data and convert them into their quantitative version, making them simpler and more readable to users. 8.
