Course objectives

  1. get familiar with fundamental econometric techniques;
  2. develop ability to reason on the appropriation of specific econometric methods;
  3. learn how to apply those econometrics in “R”;
  4. exercise interpreting and communicating results;
  • Develop practical skills of applying following empirical econometric methods in R:

    • Multiple regression analysis;
    • Panel regression analysis;
    • Binary outcome variable;
    • Instrumental variable;
    • Impact evaluation (DID and RDD);

Motivation

Have you ever heard that “vaccination causes autism”?

See (Wakefield et al., 1998).

  • A. Wakefield et, al. “Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children”. In: The Lancet 351.9103 (Feb. 1998), pp. 637-641. DOI: 10.1016/s0140-6736(97)11096-0 web-page.

  • Retracted in February 2010. See Lancet MMR autism fraud.

  • “The Lancet” is an influential journals

  • Each field has own seminal journal:

    • Ag. Econ - “American Journal of Agricultural Economics” with IF 2.245 (2017)

    • Econometrics - “Econometrica” with IF 5.84 (2020)

    • Development economics - “World Development” has the IF 5.278 (2020)

Wakefield et al. (1998). Introduction (1/2)

Research question: Early report on medical cases;

Data:

  • 12 children (mean age 6 years [range 3–10], 11 boys).

    • regularly saw a gastroenterologist;

    • had “… a history of normal development followed by loss of acquired skills, including language [autism]…”;

  • “Control” group is made post factum, artificially, matching 12 random children of the same age/gender.

Wakefield et al. (1998). Introduction (2/2)

Treatment:

  • Measles and/or MMR (measles, mumps, and rubella) vaccines at the age of 12-16 month;

Outcome:

  • Autism diagnosis [Yes/No] and linguistic disorders in 24 hours to 2 month after vaccination

  • Blood and urine sample tests out of norms at the time of research [3-10 years old];

Wakefield et al. (1998). Findings / Contributions

Vaccinated group (treatment):

  1. in 8/12 children behavioral problems [autism].

  2. intestinal abnormalities and chronic inflammation;

  3. urine tests are significantly different from “control” group;

Counter factual (12 children from the population with the same age/gender):

  1. no disorders.

  2. no abnormalities or inflammation;

  3. good tests;

  • Contributes with a theoretical mechanism of the consequences of the MMR vaccination.

Wakefield et al. (1998). Conclusions / Impact:

  1. Conclusion:

    • Mumps or MMR vaccination causes autism.
  2. Societal impact

What is wrong with Wakefield et al. (1998) ?

  • Any guesses?

  • Let us use the whiteboard…

  • By the end of this lecture, we should (ideally) be able to reason about this!

Organization

Course structure (1/4)

In presence

  • Every Wednesday 14:00 - 18:00, Room: Senckenbergstr. 03, 216 (Ze-PC2)

Course structure (2/4)

Online resources:

Course structure (3/4)

  • Lectures in person

    • Slides on Ilias.
  • Exercises (in class or at home)

    • Sometimes have pre requisites (watch a video, read a paper)

    • Sometimes require preparation in advance;

    • Sometimes are also pre-recorded.

Course structure (4/4)

Examination:

  • 60% written exam (90 minutes in the time of examination session)

  • 40% practical homework.

    • 2 short individual assignments (20% + 20%).

    • Students are expected to develop econometric analysis in R and submit it’s results (and code).

    • Homework build on the materials form the class and demonstrate ability to perform selected econometric analysis independently.
