A natural experiment is an empirical study in which individuals (or clusters of individuals) are exposed to the experimental and control conditions that are determined by nature or by other factors outside the control of the investigators. The process governing the exposures arguably resembles random assignment. Comparison Randomized controlled experiment 1.Response of subjects assigned to treatment compared to response of subjects assigned to control 2.Assignment of subjects to groups is done using a randomization device 3.Treatment is under the control of a researcher Natural experiment 1.Response of subjects assigned to treatment compared to response of subjects assigned to control … ["A natural experiment is a type of experiment conducted in the environment of the participants where the independent variable is not manipulated by the researcher but occurs naturally."] Introduction.
