This approach is called natural experiments.
Like natural experiments, matching is a design that also benefits from big data sources.
Two approaches that especially benefit from the digital age are matching and natural experiments.
For more on how natural experiments can be very tricky to interpret, see Sekhon and Titiunik(2012).
Fair comparisons cancome from either randomized controlled experiments or natural experiments.
In practice, the confidence we have in natural experiments frequently hinges on the plausibility of this“as-if” random claim.
Two approaches that especiallybenefit from big data sources are natural experiments and matching.
With natural experiments researchers have less control over things like recruitment of participants, randomization, and the nature of the treatment.
In practice, researchers use two different strategies for finding natural experiments, both of which can be fruitful.
I will use it to further discuss natural experiments like the one by Angrist(1990) on the effect of military service on earnings.
The growth of always-on, big data systems increases ourability to effectively use two existing methods: natural experiments and matching.
Then, I will use it to further discuss natural experiments like the one by Angrist(1990) on the effect of military service on earnings.
Two features of big data sources- their always-on nature and their size-greatly enhances our ability to learn from natural experiments when they occur.
One of clearest examples of the strategy of using natural experiments comes from the research of Angrist(1990) that measures the effect of military services on earnings.
The concept of fair comparisons that motivated the desires to doexperiments also underlies the two alternative approaches: natural experiments and matching.
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. .
For machine learning approaches that attempt to automatically discover natural experiments inside of big data sources, see Jensen et al.
The key difference between natural experiments and matching is that in natural experiments the researcher knows the process through which treatment was assigned and believes it to be random.
In conclusion, estimating causal effects from non-experimental data is difficult,but approaches such as natural experiments and statistical adjustments(e.g., matching) can be used.
As described in Chapter 2, natural experiments are situations where something happens in the world that approximates the random assignment of treatments(e.g., a lottery to decide who will be drafted into the military).
In chapter 4, I will describe how randomized controlled experiments can help researchers make causal estimates, and here I will describehow researchers can take advantage of natural experiments, such as the draft lottery.
Deaton(2010) and Heckman and Urzúa(2010) argue that focusing on natural experiments can lead researchers to focus on estimating unimportant causal effects;

Random event+ always-on data system= natural experiment.
We had a little natural experiment.
(2014) were exploiting whatcould be called an Emotional Contagion natural experiment.
For example, rather than running an experiment, the researchers could have exploited a natural experiment.
