Opportunity Costs: Further Evidence Through an Experimental Replication.

The article refers to Becker, Ronen, and Sorter (1974), or BRS, and reports on a replication study at the University of Colorado, which focused on the use of opportunity-cost information in the managerial decision-making process. Participants in the BRS study had to choose one of two investment projects, which were classified in four categories: equal margin-equal revenue (EMER); equal margin-unequal revenue (EMUR); unequal margin-equal revenue (UMER); and unequal margin-unequal revenue (UMUR). The three-stage laboratory study included a redesign of the BRS experiment and three experimental choices. Chi-square analysis is mentioned, as well as equations for normal approximation to binomial distribution and for population proportion. Results from the replication study differed from BRS.
