15 pages, Increasing popularity of economic experiments for policy impact analysis has led to an on-going debate about the suitability of students to substitute professionals as experimental subjects. To date, subject pool effects in agricultural and resource economics experiments have not been sufficiently studied. In order to identify differences and similarities between students and non-students, we carry out an experiment in the form of a multi-period business management game that is adapted to an agri-environmental context. We compare the compliance behaviour of German agricultural students and German farmers with regard to water protection rules and analyse their responses to two different green nudge interventions. The experimental results reveal that the direction of the response to the policy treatments is similar. Even unexpected behaviour could be reproduced by the student sample. Nevertheless, the magnitude of the treatment effects differed between the two samples. This implies that experimenters in the field of agricultural and resource economics could use the subject pool of students to analyse the direction of nudge policies. If predictions should be made about the magnitude effects, we suggest using a professional subject pool.

As with all issues, messaging has the potential to influence and change an individual’s attitude. Through the lens of social judgment theory, this quasi-experimental study investigated the influence of an evidence-based message on millennial agricultural students’ attitudes towards genetically modified foods and crops, while taking into account participants’ ego-involvements for the issue. Sixty-nine undergraduate students in the College of Agriculture participated in this study – comprised of a pre-test and post-test questionnaire with an evidence-based message intervention between.
The major finding from this study was that for the issue of genetically modified foods, millennial agricultural students’ with high ego-involvement are capable of attitude change and moving their anchor points in the direction of viewing genetically modified foods and crops less favorably than prior to the evidence-based message intervention. This result was unexpected, but important. Another key finding is that the majority of millennial agricultural students reported holding favorable attitudes towards genetically modified foods. In regards to the risks of genetically modified foods, the majority of participants disagreed that there is any risk associated with eating genetically modified foods and were neutral towards any environmental risks of genetically modified crops. This study also investigated the role of ego-involvement and the widths of the latitudes of acceptance, noncommitment, and rejection. While there was a trend for the latitude of acceptance to increase and for the latitude of rejection to decrease for both the high and low ego-involvement groups, these findings were insignificant.
Overall, this study’s findings provides great insight to science communicators who are messaging with the goal of influencing attitude change. Utilizing key elements of science communication including, weight of evidence reporting, weight of experts reporting, reinforcement of self-identity, credibility, valence, and framing theory, it is possible to influence attitude change, at least for millennial agricultural students with high ego-involvement for the issue of genetically modified foods. Future research should expand to include other segments of the population, as well as other science issues.
Evidence from a longitudinal study stuggests that many agricultural college students lack opinions on soil and water conservation issues. The data also sugges that encounters with conservation issues in the classroom and elsewhere encourage students, especially those with less direct agricultural experience, to learn about and form opinions on conservation.
