Unfulfilled Promise: Laboratory experiments in public management research

Abstract: We make the case for increased laboratory experimentation in public management research. Laboratory experiments can generate useful knowledge, particularly in testing causal relationships among constructs of interest. The challenge in this regard is one of identifying the appropriate role for experiments in a greater knowledge production enterprise. Although laboratory experiments are underutilized, they have proffered important knowledge contributions to the field, especially in areas of decision-making and, increasingly, motivation. Because practical problems may pose a greater obstacle to laboratory experimentation in public management than epistemological issues, we address external validity and the cost of conducting laboratory experiments before concluding with suggestions for future research.
