Expected Utility without Continuity: A Comment on Delbaen, Drapeau, and Kupper (2011)
This paper presents preference axiomatizations of expected utility for nonsimple lotteries while avoiding continuity constraints. We use results by Fishburn (1975), Wakker (1993), and Kopylov (2010) to generalize results by Delbaen, Drapeau, and Kupper (2011). We explain the logical relations between these contributions for risk versus uncertainty, and for finite versus countable additivity, in...
متن کاملComment on Yuan Et Al
It has come to our attention that the work of Yuan et al. [1] is being represented as definitive regarding the existence of a particular nonstrange, isoscalar, spin three dibaryon, d * , which we [2] , among others [3, 4, 5, 6, 8] , have proposed exists. We therefore wish to comment on this paper and its relation to ours and those of others. In our work [2] , the d * dibaryon is constructed in ...
متن کاملTime Continuity and Nonadditive Expected Utility
Assume that a decision maker assesses the worth of the lottery Xn for each n. Assume also that for each n, Xn is preferred to Y . Now, consider the situation where Xn converges, in some sense, to the lottery X. If X is preferred to Y , then the preference order is referred to as time continuous (Gilboa [7]). Information consisting of probabilities of some (but maybe not all) events induces an i...
متن کاملComment on study by Backman et al
BfArM acknowledges the submission of the manuscript by Backman et al. (2005) concerning the occurrence of breast cancer associated with Mirena use. The manuscript was scheduled for publication in October 2005 and meanwhile has been published (Backman T. et al. Use of the Levonorgestrel-releasing intrauterine system and breast cancer. Obstet and Gynecol 2005;106:813-7). Unfortunately, the study ...
متن کاملComment on Article by Celeux Et Al
The authors point to several problems occurring if DIC = 2D(θ) − D(θ) is applied to missing data models: (i) the focus of the model depends on whether the missing data z are considered as observations or as parameters or integrated out; (ii) the parameter θ may be non-identifiable; (iii) θ can be a poor estimator of θ. They then investigate modifications of DIC mainly based on estimates other t...
