{% Risk averse for gains, risk seeking for losses: find the predictions of prospect theory for below-target banks confirmed for data from 142 banks.
P. 86, “Theoretically, if the utility functions of bank managers do contain convex segments below target, models of the banking firm that assume universal risk aversion or risk neutrality are improperly specified. The results of this study suggest that the concepts of target outcome and distance below target should be incorporated into models that rely on risk preference assumptions. The target return is the point of inflection of the utility function and outcomes below target may induce significantly different levels of risk tolerance. Furthermore, the distance below target can affect the degree of change in risk tolerance. It is clear that models of the banking firm may be at best imprecise without considering the possibility of convex segments of the utility function below target.”

{% For subjective probabilities, makes the well known distinction between balance and weight. Then there is a third dimension, specificity. It apparently means something like whether all pieces of info that led to the probability assessment supported that probability assessment, or if some pieces supported higher probability assessments and others supported lower ones. Probably similar to expert aggregation where a difference is made between imprecise and conflicting expert judgments. In the author’s approach if no probability measure is known then it must be a set of probability measures (as with people who always exclusively think in terms of sets of priors). Then specificity for some event is maximal if all probability measures in the set of priors assign the same probability to that event. I do not really see that this would be a new dimension apart from balance and weight.
The paper assumes that if your credal state is not reflected by one probability measure, then it is by a set of probability measures. (I did not see it refer to higher-order beliefs with 2nd-order probabilities over those probability measures.) It does not look much into alternatives. P. 154 claims to show that it can only be this. The paper also takes Bayesianism not to assume completeness of preference and, hence, not one unique probability measure (§2 l. 2).
The paper uses the term bias not in the sense of mistake, but in the sense of subjective info.

{% Application of ambiguity theory;
Assume repeated decisions at time points 1, 2, …, where at each time point the smooth model of KMM holds, and a recursive model is used. They emphasize that they get a clear separation between risk attitude (vNM utility), ambiguity (the 2nd order probability distribution of the smooth model), ambiguity aversion (through the second-order utility function of the smooth model), and intertemporal preference. Many models in the literature are special cases of their general setup. They take a tractable version of their model and use it to analyze dynamic asset-price phenomena, where they can accommodate many phenomena. A problem may be that the model is very general.
P. 560 top cites puzzles in asset markets/macroeconomics.
P. 561 Footnote 3 cites ambiguity/robustness for finance.

{% PT, applications, loss aversion; Presented in Chantilly, 1997; Consider data of 10 years of horse race betting in UK. Note that this concerns a population that is more risk seeking than average. So, for instance, the certainty effect typically should not be expected to occur; it indeed didn’t.
They observe what the betting odds are for many races. This and the results of the races is the only data they use, and they do not use data about the stakes bet on various horses. They assume one representative agent, and assume that the betting odds are such that the agent is indifferent between all horses. This follows from market equilibrium: if one horse was better, betting on it would increase and, hence, its prices. From this assumption alone (their Eq. 1), they can derive both the probabilities of horses winning and the (risk-)preference functional of the bettors. It works as follows. First, for each preference functional given, the indifference between all horses gives n1 equations, enough to get the n probabilities (that add to 1). Then, for each preference functional, a proper scoring rule is calculated relative to the actual winning horses. Finally, the preference functional is chosen with the best scoring rule.
Find that RDU does not improve on EU, but PT does. They cannot incorporate loss aversion (utility more steep for losses than for gains) because the data do not permit. The better performance of PT results from different probability weighting for gains than for losses.
Weighted utility does not seem to fit the data well (p. 528).
The data do not suggest inverse-S. PT estimations suggest convex (pessimistic) w for gains, concave for losses (also pessimistic, because of dual integration for losses that PT does). For losses they seem to find risk aversion, for gains a little risk seeking. This is contrary to the common empirical findings although their footnote 17 suggests that it is in agreement with common findings. This population of betters can obviously not be expected to agree with general findings. %}

The authors consider probability weighting but it is not clear if for three-outcome prospects as considered in their experiment they do rank-dependent or separate outcome transformation. They do not seem to consider loss aversion, only different utility and probability weighting for losses, only mentioning once that they find no “discrete loss aversion” (p. 624 just above Conclusion) without specifying what it means. They measure risk aversion as preference for increasing variance.
