We introduced the multiple linear regression model, discussed the FWL Theorem and its modern uses in econometrics (and also in machine learning - briefly), and then we focused on the assumptions for the unbiasedness of the OLS estimator proving the unbiasedness of the OLS estimator under these assumptions.

We continued to discuss about the method of moments to obtain the OLS estimates. We also justified the the name of OLS estimator by using calculus. We discussed about fitted values, residuals, and looked at the example on the US data on education and wages.

We discussed the steps of an empirical project, and started an example of an empirical study about returns to education. We discussed how to specify a model and justified the simple linear model. The we discussed the different types of data. and started to derive the OLS estimates by the method of moments.
