Evaluating outcomes between the states, the analysis discovered that employment at quick meals eating places was not affected by a rise in New Jersey’s minimal wage.
Mr. Angrist and Mr. Imbens have contributed to the best way researchers take into consideration and analyze pure experiments.
They confirmed that it’s doable to establish a transparent impact from an intervention in folks’s habits — like a subsidy which may encourage folks to experience bicycles to work — even when a researcher can not management who takes half within the experiment, and even when the impression varies throughout people. The pair additionally got here up with a clear framework for such analysis that has elevated belief in it.
