These considerations add to thecontroversy of the normative justification of transitivity andcompleteness as rationality requirements. “People do andshould act as problem solvers, not maximizers, because they havemany different and incommensurable … goals to achieve”(Kranz 1991, 34). Relata of combinative preferences typically are not specified enoughto be mutually exclusive. To say that one prefers having a dog overhaving a cat does neglect the possibility that one may have both at thesame time. Depending on how one interprets it, the preferenceexpression may say very different things.

1 Choice functions and their properties

Externalinfluence models attempt to establish general links between externalevents and agents’ preference formations. They include, for example,social imitation (Leibenstein 1950), parental influence(Cavalli-Sforza 1973), habit formation (Pollack 1976), or the effectof production patterns on consumption (Duesenberry 1949). Internalcoherence models take certain external influences as given, and modelthe preference change as an accommodation of these externalinfluences.

1. Each partner may have a different approach to decision making (e.g., one more deliberative, the other more intuitive) with such discrepancies having implications for dyadic processes, decision quality, and satisfaction with the outcome.
2. For instance, recall that whendeciding between two risky options you should, according toSavage’s version of the theory, ignore the states of the worldwhere the two options result in the same outcome.
3. Then since \(p\cup q\) iscompatible with the truth of either the more or the less desirable ofthe two, \(p\cup q\)’s desirability should fall strictly betweenthat of \(p\) and that of \(q\).
4. Therefore, Humeans conclude,preferences can only be criticised if they areextrinsic—i.e.
5. When the above holds, we say that there is an expected utilityfunction that represents the agent’s preferences; in otherwords, the agent can be represented as maximising expectedutility.

Then, however, it would be sensible fori1 and i2 to form instead acoalition in favour of B. Futurepreferences may differ from present preferences because their relata(or the agent’s beliefs about the relata) have changed. They mayfurther differ because the agent’s subjective evaluation of the relatahas changed. Last, even if future preferences do not differ frompresent preferences on these two accounts, future preferences maydiffer because they are formed from another point of view than presentpreferences are. But even if preferences cannot be directly manipulated by volition,insight into the inappropriateness of a preference may motivateengaging in (non-rational) processes or putting oneself in particularcircumstances thatfacilitate preference change.

Research on aging and decision making posits that while cognitive ability declines in older age, interpersonal resources, especially the ability to use affective information and regulate emotions in decision making, are maintained (Peters et al., 2007). The ability to deal with interpersonal challenges (including the emotions that may arise) is particularly important to consider in the context of dyadic decision making, where couples are regulating their own emotions together with their partner (Berg, Wiebe, & Butner, 2010).

Modeling human behaviour

Consequently, these authors take the formal relations presented in this section as the determinants of the ontological question what preferences are. Furthermore, they also reject the interpretation of preferences as causes of choice, instead insisting that they only capture choice patterns (Binmore 2008, 19–22). The most convenient way to represent problems with multiple preferenceaspects is to introduce a vector \(\langle \succcurlyeq_1 ,\ldots,\succcurlyeq_n \rangle\) whose elements are the preference relationswe have to take into account. For simplicity, we can assume that allthese preferences are complete (or we can treat incompleteness asindifference).

As discussed in section 3.1, for situations that specify choices overall subsets (up to three elements) of the alternative set, WARP alsoensures that the relation ≽C is transitive. For practical purposes, however, this method is notvery helpful, as the space of prices and goods bundles is verylarge. Social scientists do not have the resources to observe agents’choices from all relevant preference sets. If they want toderive a transitive preference relation from a choice function notdefined over all subsets (up to three elements), then they have torestrict themselves to consider only choices that satisfy thestrong axiom of revealed preferences (SARP).

Debates internal to the field have tended to focus on complex nuances of the formal theory as well as the suitability of associating consistency of choice with choices characterized by narrow self-interest. Whereas the former is previously touched on, the latter attempt, for example, is what are the seven internal control procedures in accounting to determine if altruistic behaviour can be consistent with rational choice. Researchers generally agree that altruistic preferences could be readily encompassed within rational choice theory, but this leaves open the question of whether a satisfactory concept of altruism can be reduced to agents’ preferences over outcomes. Rational choice theory, school of thought based on the assumption that individuals choose a course of action that is most in line with their personal preferences. Rational choice theory increasingly is applied to other areas as well, including evolutionary theory, political science, and warfare. The Allais paradox, discussed in Section2.3 above, is a classic example where the aforementionedseparability fails.

Regret has been studied in the medical decision-making literature, measuring individuals’ satisfaction with their chosen medical treatment. In the couple context, regrets versus satisfaction about the decision may be negotiated and discussed, with the possibility that such post-decision processes guide future dyadic processes. For instance, when couples are satisfied with a decision outcome, they are less likely to use coercive strategies in subsequent decision-making scenarios (Su, Fern, & Ye, 2003). The repeated nature of both everyday consumer decisions and more consequential financial and medical decisions highlights the importance of understanding the ways in which are deferred income taxes operating assets individuals within couples navigate the decision-making process and the temporal relations among specific decisions.

In this section, we overview the investigated consequences of patient involvement as reported in the literature. We identify three types of investigated effects – health outcomes, patient satisfaction, and health care costs. Empowerment can be described as a state of mind in which individuals or groups gain control over certain aspects of their lives by initiating an active and participatory role. In some cases, empowerment is described as external support provided to enable individuals.

In 1938 hesuggested to “start anew … dropping off the last vestigesof the utility analysis” (1938, pp. 61–62). Preferenceswere supposed to be defined in terms of choice, thus eliminatingreference to mental states altogether. Although this approach was highly influential atthe time, economists have largely not followed Samuelson in thisradical proposal (Hausman 2012), and it might indeed be the case thatSamuelson himself later changed his mind (Hands 2014). With theincreasing convergence of (parts of) economics and psychology, theordinal psychological interpretation of preferences appears tocurrently dominate in these disciplines.
