FIELD EXPERIMENTS AND CONTROL

Glenn Harrison

A chapter in Field Experiments in Economics, 2005, pp 17-50 from Emerald Group Publishing Limited

Abstract: If we are to examine the role of “controls” in different experimental settings, it is appropriate that the word be defined carefully. TheOxford English Dictionary(Second Edition) defines the verb “control” in the following manner: “To exercise restraint or direction upon the free action of; to hold sway over, exercise power or authority over; to dominate, command.” So the word means something more active and interventionist than is suggested by it’s colloquial clinical usage. Control can include such mundane things as ensuring sterile equipment in a chemistry lab, to restrain the free flow of germs and unwanted particles that might contaminate some test.
