Chapter 1, 2, 7, 8
Introduction to the Welfare State and the Health Care Market
Causality: i.e., relationship between health and SES, impact of policy changes on numerous outcome measures,
the impact of education on wages etc.
Difference between causality and correlation
• Correlation = do observations with higher X also have higher Y? > does not imply
causation!
• Reverse causality = Y could causality affect X;
• Confounding factors = other factors causally affecting both X and Y (= variable
bias);
• I.e., what is the causal effect of health on income?
o Reverse causality = income affects health;
o Confounding factors = education affects both health and income.
Various ways of estimating causal effects
• RCT: to ensure that any observed difference is due to treatment.
o Random assign different health levels to individuals:
§ Any confounders should have similar impact on treated and non-treated individuals;
§ Can check differences in observable characteristics;
§ Reverse causality also ruled out due to randomization;
§ But feasibility? In some cases, yes, in this example no!
• Difference-in-difference: use a control group as counterfactual;
o Assume a new type of medication comes available for a disease: improvement in health level
for patients;
o Medication only available for young individuals: use old individuals as control group:
§ Test using pre-trends;
§ Control for (constant) pre-treatment differences due to differences in for example the
level of health;
§ Control for time effects that affect both groups: Recessions etc.
• Regression discontinuity: use strict thresholds in which the variable of interst 'jumps' to estimate Local
Average Treatment Effect (LATE):
o Sharp: probability of treatment increases from 0 to 1;
o Fuzzy: probability of treatment increases;
o Effect of Covid-19 vaccination on income:
§ Vaccinated and non-vacciated people are different: confounding factors;
§ Income might determine whether you get vaccinated: reverse causality;
§ Assume age threshold for Covid-19 vaccin of 30 years old: individuals aged 29 years
and 364 days not (yet) vaccinated, individuals aged 30 years (possibly) vaccinated;
§ Young individuals will become vaccinated later, so cannot use difference-in-
difference;
§ But individuals below the threshold are very similar to individuals above the age
threshold, so we can compare around the threshold.
• Instrumental variables: use an instrument that shock your variables of
interest, without affecting the confounders or outcome variable directly.
o Estimate the effect of the instrument on the variable of interest;
o Estimate the effect of the change in variable of interest due to the
IV, on the outcome Y.
• Always test your confounders.
