    We investigate the feasibility of inferring economic choices from simple biometric non-choice data. We employ a machine learning approach to assess whether biometric data acquired during sleep, naturally occurring daily chores and participation in an experi-ment can reveal preferences for competitive and team-based compensation schemes. We find that biometric data acquired using wearable devices enable equally accurate out-of-sample prediction for compensation-scheme choice as gender and performance. Our re-sults demonstrate the feasibility of inferring economic choices from simple biometric data without observing past decisions. However, we find that biometric data recorded in nat-urally occurring environments during daily chores and sleep add little value to out-of-sample predictions. (c) 2021 The Authors.

    Pragmatics and Beyond New Series
    This chapter explores the potential existence of interactional reciprocity in human–dog interactions by analyzing experimental data on situations where dog owners fail to produce reciprocally modified actions for two minutes. We found that their dogs soon realized the strangeness of the situation. While they pursued missing feedback with touch, gaze and vocalizations, they also addressed other humans and requested their attention. Therefore, the dogs oriented to the lack of reciprocity and attempted to repair it. We demonstrate that interactional reciprocity in human–dog interactions can be breached, thus proving its existence. Moreover, we show that it also returned when the experiment ended. The findings are compared with mother–infant experiments where evidence of interactional reciprocity has also been found.

    In this paper we conduct a within-subjects experiment in which teenagers go over 256 gambles with real money gains and losses. For each risky gamble they choose whether to participate in it, or pass. Prior to this main experiment subjects identify specific songs belonging to their favorite musical genre, as well as songs representing a style they dislike.In the main experiment we vary the music playing in the background, so that each subject hears some of their favorite music, and some disliked music, alternating in blocks of 16 gambles. We find that favorite music increases risk-taking (‘risk on’), and disliked music suppresses risk-taking (‘risk off’), compared to a baseline of no music. Literature in psychology proposes several mechanisms by which mood affects risk-taking, but none of them fully explain the results in our setting. The results are, however, consistent with the economics notion of preference complementarity, extended to the domain of risk preference. The preference structure implied by our results is more complex than previously thought, yet realistic, and consistent with recent theoretical models. More generally, this mechanism offers a potential explanation to why risk-taking is known to change over time and across contexts.
