A commonly held view is that laboratory experiments provide researchers with more “control” than natural field … experiments, and that this advantage is to be balanced against the disadvantage that laboratory experiments are less generalizable …. This paper presents a simple model that explores circumstances under which natural field experiments provide researchers …
