Comparing Compliance Behaviour of Students and Farmers. An Extra-laboratory Experiment in the Context of Agri-environmental Nudges in Germany

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.     

Displaying expected values in risk elicitation tasks: the effect of information in experimental risk research

We investigate the influence of providing expected lottery results to experiment participants in two common risk attitude elicitation tasks. In a between-subject design, either the Holt and Laury task or the Eckel and Grossman task is carried out by a sample of 208 students. We find no significant effect of shown expected values on the risk attitude measured by the tasks. This result even holds true if we divide the experiment participants into specific sub-groups, i.e. female and male, or lower numeracy and higher numeracy participants. Furthermore, comprehension and processing time are not significantly influenced by presented expected values. Therefore, we conclude that providing information on expected values does not influence decision-making in tasks involving risk. This result indicates the robustness of elicited risk attitudes to variation in common experimental methods, and demonstrates that more information could be provided without creating bias in the results.     

Personalized charity advertising. Can personalized prosocial messages promote empathy,attitude change,and helping intentions toward stigmatized social groups?

This study examines the role of personalized charity advertising in promoting empathy, attitude change, and helping intentions toward stigmatized social groups. Based on theories of message involvement, empathy, and reactance, we predicted that higher levels of involvement elicited by a personalized charity advertisement would reinforce empathy and prosocial outcomes. An online experiment was conducted using a personalized and a nonpersonalized version of a charity advertisement for a campaign soliciting donations of winter coats for homeless people. As expected, structural equation modeling revealed a positive indirect effect of personalization on prosocial outcomes (attitudes and behavioural intentions toward homeless people, and willingness to donate to the campaign) that was mediated by involvement and empathy. However, in addition to promoting involvement and empathy, personalization also led to heightened reactance, which detracted from the positive effects. Theoretical as well as practical implications of the findings for personalized charity advertising are discussed.

ASYMMETRY OF CUSTOMER LOSS AND RECOVERY UNDER ENDOGENOUS PARTNERSHIPS: THEORY AND EVIDENCE*

This article is inspired by real‐world phenomena that firms lose customers based on imprecise information and take a long time to recover. If consumers are playing an ordinary repeated game with fixed partners, there is no clear reason why recovery happens slowly. However, if consumers are playing an endogenously repeated game, a class of simple efficient equilibria exhibits the asymmetry of fast loss and slow recovery of customers after a bad signal. Exit is systematic, but formation of a new partnership is random. We also give empirical evidence of our equilibria at an individual‐firm level.
