EC 421, Spring 2019

Welcome to Economics 421: Introduction to Econometrics (Spring 2019) at the University of Oregon (w/ Ed Rubin).

For information on the course specifics, please see the syllabus.

Lecture slides

The slides below (linked by their topic) are .html files that will only work properly if you are connected to the internet. If you're going off grid, grab the PDFs (you'll miss out on gifs and interactive plots, but the equations will render correctly). I create the slides with xaringan in R. Thanks go to Grant McDermott for helping/pushing me to get going with xaringan.

  1. The introduction to "Introduction to Econometrics"
    PDF | .Rmd
  2. Review of key math/stat/metrics topics
    Density functions, deriving the OLS estimators, properties of estimators, statistical inference (standard errors, confidence intervals, hypothesis testing), simulation
    PDF | PDF (no pauses) | .Rmd
  3. Review of key metrics topics
    OLS properties and inference
    PDF | PDF (no pauses) | .Rmd
  4. Heteroskedasticity
    Step 1 in relaxing our assumptions: non-constant variance in our disturbances. How can we test this assumption? What are the implications of violations?
    PDF | PDF (no pauses) | .Rmd
  5. Heteroskedasticity II
    What do we do when we detect heteroskedasticity? Model specification, weighted least squares (WLS), and heteroskedasticity-robust standard errors (plus a simulation).
    PDF | PDF (no pauses) | .Rmd
  6. Consistency
    Moving from small-sample properties to asymptopia (i.e., as N gets big).
    PDF | PDF (no pauses) | .Rmd
  7. Time series
    What happens when you have repeated observations on an individual?
    PDF | PDF (no pauses) | .Rmd

Problem sets

  1. Problem set 1: Review of OLS
    PDF | Data | Solutions
  2. Problem set 2: Unbiasedness, consistency, and heteroskedasticity
