Stochastic Choice and Preferences for Randomization

Abstract: We conduct an experiment in which subjects face the same questions repeated multiple times, with repetitions of two types: (1) following the literature, the repetitions are distant from each other; (2) in a novel treatment, the repetitions are in a row, and subjects are told that the questions will be repeated. We find that a large majority of subjects exhibit stochastic choice in both cases. We discuss the implications for models of stochastic choice.

“…2 The pattern of stochastic choice was first reported in Tversky (1969). A large literature followed: focusing on choices between risky gambles (as in our model), see Camerer (1989), Starmer and Sugden (1989), Hey and Orme (1994), Ballinger and Wilcox (1997), Hey (2001), Regenwetter et al (2011), Regenwetter and Davis-Stober (2012), and Agranov and Ortoleva (2017).…”

“…Recent experimental evidence supports the interpretation of stochastic choice as deliberate. Agranov and Ortoleva (2017) show how subjects give different answers also when the same question is asked three times in a row and subjects are aware of the repetition; they seem to explicitly choose to report different answers. 5 Dwenger et al (2016) find that a large fraction of subjects choose lotteries between available allocations, indicating an explicit preference for randomization.…”

“…Instead, in these situations, one could evaluate certainty equivalents for single decisions in isolation (again, see Harrison et al [11] for an example of this). Although I discuss the Baseline and Alternative models as prescribing deterministic choices if the probabilistic component of choice is removed, this framework can include models that permit deliberate randomization (e.g., Agranov and Ortoleva [16]). For example, if the alternative model prescribed deliberate randomization, then this would be reflected in ρ V i (the alternative type's action space would have to be changed to probabilities over the experiments actions, rather than the actions themselves).…”

“…Figure 6, shows the rationalizable opportunity cost of subjects being the alternative type and making probabilistic choices. While these costs, had the BP rule prescribed many different actions to the AP rule, could be in the £15-35 range, 16 in fact the BP decision rule incurs an opportunity cost of less than £4 for all subjects. That is, relative to the range of certainty equivalents that subjects could achieve, the BP rule appears to have a small total rationalizable opportunity cost.…”
