{% In his JET 2009 paper he took discounting model with time-dependent utility. Here he takes outcome-dependent discounting. This is, of course, very unidentifiable, where we can always redefine a new outcome-dependent discount function as simply the product of utility and discounting, with then utility constant 1. He then observes that timed outcomes (only at one time point a nonzero outcome) do not identify discounting. Even if discounting is outcome independent, so not dependent, then such a multiplicative representation indeed gives the utility and discount functions up to a joint power only, leaving power unidentifiable. Standard measurement theorems show that with more than one nonzero outcome, the power and the whole model become identifiable. The author shows how we can derive functional equations from preference, basically by translating into present value. He uses a variation of the Thomsen axiom to get discounting outcome-independent. %}

{% Information Technology (IT) project escalation can result from the deaf effect: if the decision maker fails to heed risk warnings communicated by others. This paper investigates how the MRR (messenger (= auditor)-receiver-relation) impacts the deaf effect. If the messenger is collaborative then the deaf effect is smaller than if she is an opponent. They test such things in experiments. I wonder if this could be corrected for trust and selective-reporting-by-the-messenger. For prospect theory, their hypothesis H3a matters. It predicts that the influence of MRR on the deaf effect is weaker for losses than for gains. The idea is that losses give more risk seeking and, hence, more willingness to pursue. I wonder how it is in not considering risk seeking/aversion, but the CHANGE of risk seeking/aversion. Even one level more, the deaf effect itself already is not about the absolute level of risk seeking, but about a CHANGE in risk seeking.

{% probability elicitation: applied to experimental economics; proper scoring rules-correction: elicit subjective probabilities of beliefs about opponents’ strategy choices in a 2 by 2 game. They also estimate such probabilities based on (recency-overweighted) observed choice frequencies of opponent’s choices (fictitious-play beliefs). The subjective probability expressed by a player better predicts his strategy choice than the other probability. Although the authors emphasize this finding much, it is in fact trivial! The subjective probabilities, depicted for instance in Figure 2 on p. 980, are too extreme and variable (and remain so, see top of p. 981), and often are 0 or 1. This suggests that subjects took these as proxies/justifications of what their own strategy choices would be (as per the referee’s/editor’s suggestion in footnote 20 on p. 986), and did not understand the proper scoring rules.
The subjective probability judgments predict the opponent’s strategy choices worse than the observed-frequency estimations (§3.1.3 at pp. 985 ff) according to Brier scores. The linear distance, advanced by the authors in defense of subjective probabilities at the end of §3.1.3, is not proper and should not be considered. For instance, it favors always estimating a probability as 1 as soon as the true probability exceeds 0.5 and, thus, favors extreme judgments rather than true judgments. %}

{% dynamic consistency; Paper deals with sophisticated choice and naive choice, so it does not consider resolute choice and assumes that dynamic consistency in the strong sense is violated. It assumes constant zero discounting with one exception: the presence, the current period, receives higher weight (present-biased preference). It assumes that one action has to be chosen only one time (e.g. write a report), yielding a cost at some later time and a reward at some, possibly different, later time. §IV considers what the authors call welfare considerations, meaning the undiscounted total utility. This terminology suggests that the authors view zero discounting as normative, an assumption to which I am sympathetic.
For costs, sophistication counters the overweighting of the presence which is always good from the zero-discounting normative perspective (Proposition 3). For current reward, sophistication can do anything, also exacerbate the present-bias (Example 2). E.g. the sophisticated person foresees that he will exhibit presence-bias in the future and therefore consume “too” soon, which decrease in future utility is just enough to make him completely give in to current presence-bias and consume immediately. He thereby lowers the normative undiscounted total utility. %}

{% In a careful experiment, ambiguity is generated by balls falling through an irregular Galton box, just created by volunteer students hammering nails in it not knowing for what purpose. This box was used to determine the composition of Ellsberg urns. It is called mechanical ambiguity because it results from a process with no deliberate human beings involved (probably meant: human beings who can rig the urn), and the experimenters not able to know. They compare with ambiguity that is generated by a human being which they call strategic (probably having in mind that this can involve rigging the urn and, hence, they do not control for suspicion and do not allow subjects to choose the color to bet on; suspicion under ambiguity), finding a null hypothesis of no difference (the choice percentages of 37.7% and 45.5% are not significantly different in a between-subject treatment of 53 subjects versus 121 subjects, suffering from the small power of between-subjects designs).
Each subject did only one choice, so as to have no income effects and no need for RIS (which is especially problematic for ambiguity because the risk involved in RIS interferes with ambiguity). The authors also correct for indifference, by letting the ambiguous option being slightly better (to be sure that unambiguous option chosen is really ambiguity aversion) and in another choice situation letting it be slightly worse (to be sure that ambiguous option chosen is really ambiguity seeking). They find some 40% ambiguity aversion but 25% ambiguity seeking (ambiguity seeking). The authors review many studies, showing that their finding is consistent with other findings. They find a null hypothesis of mechanical ambiguity being similar to strategic (human-generated) ambiguity. %}
