Like other mathematically intensive sciences, economics is becoming increasingly computerized. Despite the extent of the computation, however, there is very little true simulation. Simple computation is a form of theory articulation, whereas true simulation is analogous to an experimental procedure. Successful computation is faithful to an underlying mathematical model, whereas successful simulation directly mimics a process or a system. The computer is seen as a legitimate tool in economics only when traditional analytical solutions cannot be derived, i.e., only as a (...) purely computational aid. We argue that true simulation is seldom practiced because it does not fit the conception of understanding inherent in mainstream economics. According to this conception, understanding is constituted by analytical derivation from a set of fundamental economic axioms. We articulate this conception using the concept of economists' perfect model. Since the deductive links between the assumptions and the consequences are not transparent in ‘bottom‐up’ generative microsimulations, microsimulations cannot correspond to the perfect model and economists do not therefore consider them viable candidates for generating theories that enhance economic understanding.

Kirjasymposio Eerik Lagerspetzin Social Choice and Democratic Values – kirjasta. Kenneth Arrowia seuraten Lagerspetz pitää sosiaalisen valinnan teorian suurimpana vahvuutena sitä, että sen tuloksia voidaan käyttää monissa erilaisissa yhteyksissä. Minä taas pidän teorian suurimpana heikkoutena sen vaikeutta: tutkijat eivät ole päässeet yhteisymmärrykseen erityisesti ns. epärelevanttien vaihtoehtojen riippumattomuusehdon tulkinnasta ja muotoilusta. Lagerspetz hyväksyy kirjassaan nähdäkseni seuraavat väitteet: kaikki demokraattiset äänestyssäännöt rikkovat riippumattomuusehtoa, mutta että tuo ehto on silti normatiivisesti perusteltu. Arrow’n ehdot ovat intuitiivisesti ottaen hyväksyttävissä. Koska riippumattomuusehdon rikkoutumisesta seuraa strategista äänestämistä (...) ja strateginen äänestäminen on normatiivisesti katsottuna ei-toivottavaa tai jopa moraalisesti kyseenalaista, strategisen äänestämisen poissulkeminen olisi paras mahdollinen argumentti riippumattomuusehdon puolesta. Lisäksi säännöt jotka toteuttavat riippumattomuusehdon ovat immuuneja strategiselle käyttäytymiselle. Hyvin toimiva äänestyssääntö luo puhtaasti mekaanisen yhteyden yksilöiden mielipiteiden ja kollektiivisen valinnan välille. Tämän kirjoituksen ensisijainen tavoite on kumota jokainen edellisessä kappaleessa esitetty väite. (shrink)

Machery et al. presented data suggesting the existence of cross-cultural variation in judgments about the reference of proper names. In this paper, we examine a previously overlooked confound in the subsequent studies that attempt to replicate the results of Machery et al. using East Asian languages. Machery et al. and Sytsma et al. claim that they have successfully replicated the original finding with probes written in Chinese and Japanese, respectively. These studies, however, crucially rely on uses of articleless, ‘bare noun (...) phrases’ in Chinese and Japanese, which according to the linguistic literature are known to be multiply ambiguous. We argue that it becomes questionable whether the extant studies using East Asian languages revealed genuine cross-cultural variation when the probes are reevaluated based on a proper linguistic understanding of Chinese and Japanese bare noun phrases and English definite descriptions. We also present two experiments on native Japanese speakers that controlled the use of ambiguous bare noun phrases, the results of which suggest that the judgments of Japanese speakers concerning the reference of proper names may not diverge from those of English speakers.

Arrow's Independence of Irrelevant Alternatives (IIA) has been under criticism for decades for not taking account of preference intensities. Computer-simulation results by Aki Lehtinen concerning strategic voting under various voting rules show that this intensity argument does not need to rest on mere intuition. Voters may express intensities by voting strategically, and that this has beneficial aggregate-level consequences: utilitarian efficiency is higher if voters engage in strategic behaviour than if they always vote sincerely. Strategic voting is thus unambiguously beneficial under (...) a utilitarian evaluation of outcomes. What has been considered the main argument for IIA turns out to be one against it. This paper assesses the implications of these results for interpretations of Arrow's theorem and the Gibbard-Satterthwaite theorem in a discussion on the methodological and philosophical arguments concerning preference intensities and IIA.

Tyler Burge's theory of proper names is being revived with the help of Generative Grammar. The complex syntax of DPs appears to encourage the Burgean analysis of proper names which attributes complex semantic structures to the uses of proper names. I will argue, however, that the Millian view of proper names which hypothesizes simple semantics for names is also compatible with the complex syntactic structures. In order to defend this thesis, I will show that Paul Elbourne's implementation of Burge's insight (...) is no better than the Millian semantics of proper names. (shrink)

Derivational robustness may increase the degree to which various pieces of evidence indirectly confirm a robust result. There are two ways in which this increase may come about. First, if one can show that a result is robust, and that the various individual models used to derive it also have other confirmed results, these other results may indirectly confirm the robust result. Confirmation derives from the fact that data not known to bear on a result are shown to be relevant (...) when it is shown to be robust. Second, robustness may increase the degree to which the robust result is indirectly confirmed if it increases the weight with which existing evidence indirectly confirms it. This may happen when it strengthens the connection between the core and the robust result by showing that auxiliaries are not responsible for the result. (shrink)

The most common argument against the use of rational choice models outside economics is that they make unrealistic assumptions about individual behavior. We argue that whether the falsity of assumptions matters in a given model depends on which factors are explanatorily relevant. Since the explanatory factors may vary from application to application, effective criticism of economic model building should be based on model-specific arguments showing how the result really depends on the false assumptions. However, some modeling results in imperialistic applications (...) are relatively robust with respect to unrealistic assumptions. Key Words: unrealistic assumptions • economics imperialism • rational choice • as if • robustness. (shrink)

This paper provides a conceptual framework that allows for distinguishing between different kinds of generalisation and applicability. It is argued that generalising models may bring epistemic benefits. They do so if they show that restrictive and unrealistic assumptions do not threaten the credibility of results derived from models. There are two different notions of applicability, generic and specific, which give rise to three different kinds of generalizations. Only generalising a result brings epistemic benefits concerning the truth of model components or (...) results. Abstracting the model and applying the model into new systems are not intrinsically epistemically beneficial in this way. The Dixit-Stiglitz model of monopolistic competition is used as an illustration. (shrink)

Robustness may increase the degree to which the robust result is indirectly confirmed if it is shown to depend on confirmed rather than disconfirmed assumptions. Although increasing the weight with which existing evidence indirectly confirms it in such a case, robustness may also be irrelevant for confirmation, or may even disconfirm. Whether or not it confirms depends on the available data and on what other results have already been established.

Mental imagery of movement is a potentially valuable rehabilitation task, but its therapeutic efficacy may depend on the specific cognitive strategy employed. Individuals use two main strategies to perform the hand mental rotation task, which involves determining whether a visual image depicts a left or right hand. One is the motor imagery strategy, which involves mentally simulating one’s own hand movements. In this case, task performance as measured by response time is subject to a medial–lateral effect wherein the RT is (...) reduced when the fingertips are directed medially, presumably as the actual motion would be easier. The other strategy is to employ visual imagery, which involves mentally rotating the picture and is not subject to this medial–lateral effect. The rehabilitative benefits of the HMRT are thought to depend on the MI strategy, so it is essential to examine the effects of individual factors such as age, image perspective, and innate ability on the strategy adopted. When presented with pictures of the palm, all subjects in the current study used the MI strategy, regardless of age and ability. In contrast, when subjects were presented with pictures of the back of the hand, the VI strategy predominated among the young age group regardless of performance, while the strategy used by middle-age and elderly groups depended on performance ability. In the middle-age and elderly groups, the VI approach predominated in those with high performance skill, whereas the MI strategy predominated among those with low performance skill. Thus, higher-skill middle-aged and elderly individuals may not necessarily form a motion image during the HMRT, potentially limiting rehabilitation efficacy. (shrink)

Using Harvey Sacks’s concept of membership categorization devices, this article examines the help-search sequences in which Japanese rehabilitation team members use a set of categories to locate the availability of stroke family caregivers. Specifically, based on an analysis of audiovisual data from rehabilitation team conferences in Japan, the article illustrates the ways in which participants at the meetings: evaluate the expectable behaviors of various category incumbents; classify which category of person is proper to turn to for help; and arrive at (...) the conclusion that no one is available, and so the patient must be institutionalized. Analysis shows that participants routinely choose co-resident family members to fulfill the caregiver position. However, the position is not guaranteed unless the selected incumbent can satisfy additional criteria, especially physical strength and time availability. By exploring the ways in which participants use categories to negotiate discharge destinations, the article adds to Sacks’s analysis by illustrating methodical activities for deciding whether someone is unavailable to help. Moreover, it considers the applicability of Sacks’s notion of MCDs to Japanese data. (shrink)

Despite increasing interests and urgent needs for quality end-of-life care, there is no exact definition of what is the interval referred to as end of life or what end-of-life care is. The purpose of this article is to report our examination of terms related to end-of-life care and define end-of-life care from nursing ethics perspectives. Current terms related to end-of-life care, such as terminal care, hospice care, and palliative care, are based on a medical model and are restrictive in terms (...) of diagnosis and prognosis. Using codes of ethics for nurses as a framework, we attempt to identify people to whom nurses are responsible to provide end-of-life care and develop a definition of end-of-life care that is more inclusive and applicable to a broader range of people who would benefit from end-of-life care by nurses and other health-care providers.

This study investigates rehabilitation team members’ interactive accomplishments of their domains of work and responsibility in rehabilitation team conferences in Japan. A combination of membership categorization analysis and sequential analysis is adopted to systematically illustrate the situated productions of professional sense-making practices. Analysis focuses on the segment in which a physician asks a series of questions regarding a patient’s functional status and disability coded in the functional assessment record (FAR). A close examination of data shows that a physician does not (...) always choose a respondent with his or her gaze when asking a question because s/he is continuously reading the FAR displayed on a computer screen. Despite this, a physician’s mention of a topic generates a professional’s domain of work and responsibility in a local division of labor which is used by members to assume who the relevant categorial respondent is. Further, members demonstrate these assumptions by shifting their gazes toward the computer screen, back to the document on the desk, and turning toward co-participants, thus embodying professional roles and responsibilities in situ. This study utilizes the analyst’s ethnographic understanding of the routines and division of labor at the rehabilitation ward as a resource to explicate professional sense-making practices, thus utilizing Garfinkel’s ethnomethodological studies of work. Together with sequential and categorial resources offered by Sacks, this study elucidates inferences and normative expectations which rehabilitation team members bring together to reproduce the endogenous logic of rehabilitation culture in actual occasions of the institutional life.

This paper studies the welfare consequences of strategic voting in two commonly used parliamentary agendas by comparing the average utilities obtained in simulated voting under two behavioural assumptions: expected utility maximising behaviour and sincere behaviour. The average utility obtained in simulations is higher with expected utility maximising behaviour than with sincere voting behaviour under a broad range of assumptions. Strategic voting increases welfare particularly if the distribution of preference intensities correlates with voter types.

All economic models involve abstractions and idealisations. Economic theory itself does not tell which idealizations are truly fatal or harmful for the result and which are not. This is why much of what is seen as theoretical contribution in economics is constituted by deriving familiar results from different modelling assumptions. If a modelling result is robust with respect to particular modelling assumptions, the empirical falsity of these particular assumptions does not provide grounds for criticizing the result. In this paper we (...) demonstrate how derivational robustness analysis does carry epistemic weight and answer criticism concerning its non-empirical nature and the problematic form of the required independence of the ways of derivation. The epistemic rationale and importance of robustness analysis also challenge some common conceptions of the role of theory in economics. (shrink)

This chapter presents two cross-linguistic studies of knowledge-how attributions that compare English and Japanese speakers. The first study investigates the felicity judgements of ordinary people about knowledge-how sentences, where we find a large difference in judgements about the sentences in which a person lacks an ability to perform a certain action but is nevertheless attributed the relevant knowledge of how to perform that action. The second study investigates the frequency of the natural occurrences of knowing-how constructions in English and Japanese (...) through Google search and corpora, where we find virtually no natural occurrence of Japanese knowing-how constructions. These results suggest that the attribution of knowledge-how in Japanese is radically different from the English counterpart in that it neither requires nor is required by the relevant physical ability. We then explore the philosophical implications of these radical differences in the use of knowing-how constructions between English and Japanese speakers for the debate between intellectualism and anti-intellectualism. One such implication is that English “know how” sentences themselves may not delineate a philosophically significant category of knowledge. (shrink)

It is argued in this paper that amalgamating confirmation from various sources is relevantly different from social-choice contexts, and that proving an impossibility theorem for aggregating confirmation measures directs attention to irrelevant issues.

Among Japanese nurses ethics is perceived as being distant and unrelated to their practice, although this is filled with ethical concerns and the making of ethical decisions. The reasons for this dissociation are the primacy of western values in modern Japanese health care systems and the suppression of Japanese nurses’ indigenous ethical values because of domination by western ethics. A hermeneutic study was conducted to listen to the ethical voices of Japanese nurses. Seven ethical concerns were revealed. Although some of (...) these concerns may seem to share similar values with western ethical principles, the basis for the concerns was unique and rooted in the Japanese cultural value system. The meanings of each concern are explicated in conjunction with related background meanings. Listening and trying to understand these nurses’ voices in their own context suggests a way of bridging the gap between abstract and universal ethics and practical and local ethics. (shrink)

We claim that the process of theoretical model refinement in economics is best characterised as robustness analysis: the systematic examination of the robustness of modelling results with respect to particular modelling assumptions. We argue that this practise has epistemic value by extending William Wimsatt's account of robustness analysis as triangulation via independent means of determination. For economists robustness analysis is a crucial methodological strategy because their models are often based on idealisations and abstractions, and it is usually difficult to tell (...) which idealisations are truly harmful.

This paper provides a philosophical critique of social choice theory insofar as it deals with the normative evaluation of voting and voting rules. I will argue that the very method of evaluating voting rules in terms of whether they satisfy various conditions is deeply problematic because introducing strategic behaviour leads to a violation of any condition that makes a difference between voting rules. I also argue that it is legitimate to make interpersonal comparisons of utilities in voting theory. Combining a (...) realistic account of voters’ behaviour with a utilitarian evaluation of the outcomes then leads to the judgment that strategic voting is beneficial. If it is, then Arrow's theorem does not have far-reaching consequences for democracy because one of its conditions is not normatively acceptable. (shrink)

The functional independence measure is a clinical scale which is used to evaluate the amount of assistance disabled persons need to conduct their daily living activities. Drawing on 65 video-recorded rehabilitation team meetings and medical records collected from a Japanese hospital, this article utilizes ethnomethodology and conversation analysis to uncover how Japanese rehabilitation team members use the FIM to track changes in the functional status of patients and decide the length of stay in ongoing interactional sequences. Analysis shows that a (...) series of the FIM scores assembled and arranged in situ provide a sequential framework for members to understand the progress of rehabilitation and predict the plateau phase. Moreover, a particular expert is asked about patients’ capacity for further improvements and his or her opinions are treated as a basis for clinical decisions. In this way, diagnostic and clinical decision-making is produced through the ongoing collaborative work of various specialists. (shrink)
