Behavioral economic analyses recently have been extended to alcohol drinking among college students. The current study used a hypothetical alcohol purchase task (APT) to assess the effects of academic constraints (next-day class time and next-day class requirement) on alcohol demand among college students. Participants were asked to read a description of a drinking scenario and indicate how many standard drinks they would consume at a variety of prices. In Experiment 1, 164 participants (71% female) were randomly assigned to one of three "academic constraint" conditions, for which the scenario included a next-day class that differed by scheduled time (8:30 a.m., 10:00 a.m., or 12:30 p.m.), or a control condition (no next-day class). Exponential demand analyses revealed that participants in all three of the academic constraint conditions reported fewer drinks consumed and displayed lower "essential value" of alcohol, or greater sensitivity to price increases, compared with the no-constraint control. In Experiment 2, 66 participants (80.3% female) were randomly divided into four groups and received one of four versions of the APT, manipulated to examine class time and class requirement (8:30 a.m. class, 8:30 a.m. exam, 12:30 p.m. class, 12:30 p.m. exam). Exponential demand analyses revealed that the essential value of alcohol was lower for the two 8:30 a.m. conditions compared with the 12:30 p.m. conditions and was lowest for participants in the 8:30 a.m. exam condition compared with the other three. These results suggest that academic requirements may reduce alcohol demand among college students.
Behavioral economic principles have been useful for addressing strategies to reduce alcohol consumption among college students. For example, academic variables (such as class schedule or academic rigor) have been found to affect alcohol demand assessed with a hypothetical alcohol purchase task (APT). The present studies used the APT to address the effects of 2 academic variables: next-day course level (no class, introductory level or upper level) and class size (no class, 30-student or 12-student). In each of 2 experiments, undergraduate participants read a description of a drinking context (either a no-class control version or 1 of the academic constraint conditions) and were asked to indicate how many drinks they would purchase at a variety of prices. Hursh and Silberberg's (2008) exponential demand equation was used to determine intensity and elasticity of demand, and Hursh and Roma's (2015) essential value (EV) parameter was calculated to assess essential value. In both experiments, a next-day class reduced alcohol demand, and alcohol consumption decreased as drink price increased. The presence of a smaller next-day class reduced alcohol demand compared with a larger next-day class; however, course level did not differentially affect alcohol demand. These results suggest that smaller next-day classes may reduce alcohol demand among college students and also provide initial evidence for the reliability of EV across studies.
