offer a clear introduction into the differences between experiments, controlled experiments, and randomized controlled experiments.
It's enough to remember the experiments that Russian scientist Pavlov did with the dogs and everything becomes clear to us.
For example, psychologists tend to move beyond simple experiments by focusing on mediators and moderators(Baron and Kenny 1986).
governments- can increasingly systematically intervene in people's lives in order to create randomized controlled experiments.
Often natural experiments are the best way to estimate cause-and-effect relationships in settings where it is not ethical or practical to run randomized controlled experiments.
But, if you don't work at a tech company you might think that you can't run digital experiments. Fortunately, that's wrong;
this enables researchers to run experiments that were impossible in the past.
Then, I will use it to further discuss natural experiments like the one by Angrist(1990) on the effect of military service on earnings.
For an example of how these ethical frameworks can be applied to field experiments in develop economics, see Baele(2013).
Note that this approach to designing enjoyable experiments echoes some of the themes in Chapter 3 regarding designing more enjoyable surveys
Clinical experiments observed that the drug caused deaths in juvenile mice with ages that are equivalent to below 6 years in humans.
Most analog age experiments involve a small number of participants that are treated as interchangeable“widgets” because little about them is known pre-treatment.
While digital field experiments offer many possibilities,
Researchers running massive online experiments often justify the importance of small estimated treatment effects by saying that these small effects can become important when applied to many people.
A further idea related to informed consent that has been proposed is to build a panel of people who agree to be in online experiments(Crawford 2014).
These experiments are part of a long tradition of experiments in political science on efforts to encourage voting(Green and Gerber 2015).
Social experiments are experiments where the treatment is some social policy that can only be implemented by a government.
Further, field experiments are sufficiently expensive that it would be infeasible to run enough of them up to cover the whole parameter space of products and auction types.
Manzi(2012) provides a fascinating and readable introduction to the philosophical and statistical underpinnings of randomized controlled experiments.
Yet, field experiments to study discrimination have been performed in at least 117 studies in 17 countries(Riach and Rich 2002; Rich 2014).
