What is the identification strategy? An identification strategy is the manner in which a researcher uses observational data (i.e., data not generated by a randomized trial) to approximate a real experiment. Are these issues with endogeneity of the explanatory variables, which are not discussed in the paper? Can you think why the dependent variable might be used to explain variation in the regressors? Are there the dependent variable might be used to explain variation in the regressors? Are there other influences on the dependent variable that are not included in the regression? Do other influences on the dependent variable that are not included in the regression? Do you think that they are correlated with the regressors? If so, what is the anticipated direction of the bias? Suggest other potential source of bias, write the data generating process, the estimating equation and the estimator. Explain why the estimator is biased.
