We argue that in extensive decision problems (extensive games with a single player) with imperfect recall care must be taken in interpreting information sets and strategies. Alternative interpretations allow for different kinds of analysis. We address the following issues: 1. randomization at information sets; 2. consistent beliefs; 3. time consistency of optimal plans; 4. the multiselves approach to decision making. We illustrate our discussion through an example that we call the ‘‘paradox of the absentminded driver.’’ Journal of Economic Literature Classification (...) Numbers: C7, D0. 1997 Academic Press.

This paper studies a decision maker who tackles a choice problem by selecting a subset of (at most) two alternatives which he will consider further in the second stage of his deliberation. We focus on the first stage where he chooses the delebration set. We axiomatize three types of procedures: (i) The top two: the decision maker has in mind an ordering and chooses the two maximal alternatives. (ii) The two extremes: the decision maker has in mind an ordering and (...) chooses the maximal and the minimal alternatives. (iii) The top and the top: the decision maker has in mind two orderings and he chooses the maximal elements. (shrink)

Lecture audiences and students were asked to respond to virtual decision and game situations at gametheory.tau.ac.il. Several thousand observations were collected and the response time for each answer was recorded. There were significant differences in response time across responses. It is suggested that choices made instinctively, that is, on the basis of an emotional response, require less response time than choices that require the use of cognitive reasoning.

A speaker wishes to persuade a listener to accept a certain request. The conditions under which the request is justified, from the listener’s point of view, depend on the values of two aspects. The values of the aspects are known only to the speaker and the listener can check the value of at most one. A mechanism specifies a set of messages that the speaker can send and a rule that determines the listener’s response, namely, which aspect he checks and (...) whether he accepts or rejects the speaker’s request. We study mechanisms that maximize the probability that the listener accepts the request when it is justified and rejects the request when it is unjustified, given that the speaker maximizes the probability that his request is accepted. We show that a simple optimal mechanism exists and can be found by solving a linear programming problem in which the set of constraints is derived from what we call the L-principle. (shrink)

How do modal expressions determine which possibilities they range over? According to the Modal Anchor Hypothesis (Kratzer in _The language-cognition interface: Actes du 19_ _e_ _congrès international des linguistes_, Libraire Droz, Genève, 179–199, 2013 ), modal expressions determine their domain of quantification from particulars (events, situations, or individuals). This paper presents novel evidence for this hypothesis, focusing on a class of Spanish relative clauses that host verbs inflected in the subjunctive. Subjunctive in Romance is standardly taken to be licensed only (...) in a subset of intensional contexts. However, in our relative clauses, subjunctive is exceptionally licensed in extensional contexts. At the same time, the interpretation of these relative clauses still involves modality, a type of modality that targets the goals of the agent of the main event. We argue that the pattern displayed by these relative clauses follows straightforwardly if subjunctive is associated with a modal operator that, like modal indefinites (Alonso-Ovalle and Menéndez-Benito in _Journal of Semantics_ 35(1):1–41, 2017 ), can project its domain from a volitional event. Overall, our proposal supports the event-based analysis of mood (Kratzer in Evidential mood in attitude and speech reports. Talk delivered at the 1st Syncart Workshop, Siena, July 13, 2016 ; Portner and Rubinstein in _Natural Language Semantics_ 28:343–393, 2020 ) and extends its application beyond attitudinal and modal complements.

For me, economics is a collection of ideas and conventions which economists accept and use to reason with. Namely, it is a culture. Behavioral economics represents a transformation of that culture. Nonetheless, as pointed out by Camerer and Loewenstein (2003), its methods are pretty much the same as those introduced by the Game Theory revolution. At the core of most models in Behavioral Economics there are still agents who maximize a preference relation over some space of consequences and the solution (...) in most cases still involves standard equilibrium concepts. However, the behavioral economists are not committed to what is usually referred to as rational motivations. An economic fable (or a model as we would call it) that has at its core fairness, envy, present-bias and the like is by now not only permitted but even preferred. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Elliot Rubinstein BUÑUEL'S WORLD, OR THE WORLD AND BUNUEL* THE line OF descent from Surrealist cinema to chosiste fiction—the line which all the remarks that follow are meant at least to trace—is, if not direct, surely collateral. But the genealogy is so complex as to resist detailing in a brief paper. What I offer may be taken for preliminaries, observations on the cinema of Bunuel prompted in large (...) part by a rereading of Robbe-Grillet's For a New Novel. ' The world of any Bunuel film is first of all, in William S. Pechter's phrase, the worst of all possible.2 But the phrase misleads, implying that better worlds are imaginable, let alone photographable, let alone otherwise available. Neithersexual fascination {L'Aged' or, El [ This Strange Passion], Ensayo de un crimen [The Criminal Life ofArchibaldo de la Cruz], Abismos de pasión [Wuthering Heights], Diary ofa Chambermaid, Belle de Jour) nor faith (Nazartn, Robinson Crusoe, Vindiana, The Milky Way), nor any other agency of spiritual transcendence delivers us to a world fit for human habitation. Trailing clouds, but not of glory, do we come, and beneath these clouds we proceed to make fools and martyrs and killers of one another, of ourselves. Unhappily, such views, seized upon as novelties, leave Buñuel at the mercy of some of the most sophomoric adulators ever to hound a major artist. Happily, Buñuel's vision justifies his views; happily, his career transcends his vision. His particular achievement is the sheer variety of worlds he has discovered or reanimated, none quite like *This article, and the one by Stanley Cavell which follows it, grew out of remarks presented at the annual convention of the Modern Language Association, December 30, 1977. The title of the symposium was "Chosisme and the Cinema: the Perception of Physical Reality in Cinema and Literature." 237 238Philosophy and Literature another except in the way it is seen—and each the worst of all possible. The world of Nazartn appears, on the relentlessly gray surface of its film stock, the most conventional in any of Buñuel's works. (I am not thinking of, for one must try to think as little as possible of, some of the potboilers Buñuel had to produce during his Mexican captivity of the late 1940s and 1950s.) Its story of a persecuted priest is left to progress without worrisome spatial or temporal discontinuities. The myth on which its story feeds, explicit in the title, is the most familiar of all, and the inescapable implications of the Quixote and of Dostoyevsky 's tale of the Grand Inquisitor further cater to our certainty of the correctness of our responses. The sole plainly Surreal moment occurs when the picture of Jesus on the priest's wall explodes into a wicked Bosch-like grin, but the image is subjective, "psychological," reflecting the delirium of a wounded prostitute whom the priest is sequestering, and seen only by her. Emotional valences are respected: there is nothing perplexing about the characters' reactions and interplayings. And things are in their place. Such an account of Nazartn recalls Robbe-Grillet's account of Balzacian fiction: All the technical elements of narrative—systematic use of the past tense and the third person, unconditional adoption of chronological development, linear plots, regular trajectory of the passions, impulses of each episode toward a conclusion, etc.—everything tended to impose the image of a stable, coherent, continuous, unequivocal, decipherable universe. Since the intelligibility of the world was not even questioned, to tell a story did not raise a problem. The style of the novel could be innocent, (p. 32) I trust there is no reason to belabor the frailness (I mean with respect to any reading of Balzac) of an argument that pushes to that last sentence. Still, the point is plain enough, and, in its way, and, in its limits, true enough. Because Nazarin (based, by the way, on a novel of Galdós) tells a story in an age when "To tell a story has become strictly impossible" (p. 33) it cannot lay claim to a place in the realm of New Narrative. But there is more to Nazarin than... (shrink)

Sophisticated Marxists have always been aware of the important contributions to literary criticism of Marx, Engels, Trotsky and Gramsci. Yet, except for Lukács, there has been almost no discussion of Lenin's great interest in literature. This paper glances at some of the contemporary evidence of Lenin's concern with the classic Russian novelists — especially Tolstoy, to whom he devoted four essays (his only works of formal literary criticism). Lenin placed great emphasis from the earliest days of the revolution on building (...) a popular library system and on publishing good fiction cheaply. He also had an informed interest in language and was a life-long opponent of literary censorship. In this connection, his struggle against the sectarianism of the Proletkult movement is recorded.

Economists generally associate the redistribution of resources with the apparatus of taxes and transfer payments. Such redistributions are done by the power of the authorities. However, resources are redistributed by other means as well. People give away income in a variety of ways, deliberate and unintentional. In this paper, agents transfer consumption goods in return for a good which lacks material qualities and affects their preferences because it has “value”. An example of a real life commodity without intrinsic value is (...) diamonds. The standard consumption value of a diamond is low, especially as artificial diamonds look the same as real ones to the naked eye. Many luxury goods such as art pieces have similar characteristics. Owning a house in a “rich” area could have extra benefits in consumption and, yet, one important motivation is simply to live in an expensive neighborhood. By holding such a good an agent refrains from acquiring resources that he could consume and, thus, frees resources for other agents. Our thinking on this issue originates from a naive question. Why are wealthy people striving to be wealthier? It is quite absurd to think that rich people wish to increase the consumption of standard goods as assumed in the classical consumer model. Indeed, by acquiring an expensive diamond or an original piece of art, a consumer demonstrates his avoidance of consumption. We construct and analyse an elementary competitive equilibrium model in which the value of “useless” jewels enter the preferences of consumers. We show that if jewels are scarce, they can trade at a positive price despite having no intrinsic utility. Under fairly natural assumptions, a positive price equilibrium redistributes consumption from the rich to the poor. Thus, the model demonstrates the common wisdom that the existence of luxury goods can have a positive effect on income distribution. This paper is mainly expository. The idea of consumption goods lacking intrinsic value and of prices entering directly the utility functions is not original.. (shrink)

The present research is the first part of econometric study of the so called sponsored goods and looks at one of the most common types of such goods namely art products created by theaters, concert organizations and museums. The aim of the paper is to analyse the performance of Russian art organizations to find out to what extend the conditions of their functioning in post Soviet times under the development of market economy, democratization of leisure and changes in consumer preferences (...) influence their economic results. Could Russian theaters, museums and concert organizations be self- sufficient in market economy established in Russian in 1991-2010?The set up task determined the object of the study and the statistical data to be used-40 years time series performance indicators that include equal time intervals-1971-1990 for performing arts organizations and 1991-2010-for theaters, concert organizations and museums. The specifics of calculations presented in the article result from the very approach to the testing of cost disease. Its essence is to reveal the symptoms of this disease in art organizations taken as an element of economy as a whole rather than only as a part of cultural activities. Accordingly a new method of diagnostics of the cost disease is suggested that is based on development of specific indexes measuring the lag of labor productivity, advancing dynamics of wages and priority growth in prices for tickets in relation to the corresponding indexes of macroeconomic dynamics as well as determination of cost disease consequences-the deficit of income of providers of cultural goods. The implementation of such an approach allowed to construct three-dimensional space which coordinates describe the dynamics of performance results of art organizations. (shrink)

I HAVE BEEN PRIVILEGED TO SERVE a society whose guiding principle and raison d’être are to serve the academic interests of its constituency, namely, economic researchers who employ rigorous methodologies. The Society has maintained a consistent range of activities over the years, but this should not deter us from discussing in the future two major questions: Should we remain within the present scope of the Society or rede- fine it to achieve a broader common denominator? Should we restrict ourselves to (...) the traditional functions of publishing the journal, organizing conferences, and conferring honors, or should we expand our activities, especially in light of recent technological advances? 2. NEW JOURNALS I will start with what I think is the most important issue that we currently face, namely whether to establish two or three additional journals that would publish worthy papers that have been rejected from Econometrica due to overspecialization. The idea is that authors would be allowed to request the transfer of referee reports from the main journal to the somewhat more specialized journals. This would speed up the process and allow for more efficient use of the scarce refereeing resources available to Econometrica. Such an idea was suggested in 2002 in the report of the Committee for Electronic Issues and received mixed reactions. A new committee will make its recommendations about the desirability of such an initiative at the upcoming meeting of the Executive Committee. I very much hope that, in spite of the reservations, the Econometric Society will take up the challenge. This would be a major step in the current campaign to exclude commercialism from publishing and would be a groundbreaking innovation in the publication procedures currently employed in economics. The choice of the domains for the “baby Econometrica” will also delineate the Society’s boundaries. (shrink)

Web scraping involves using computer programs for automated extraction and organization of data from the Web for the purpose of further data analysis and use. It is frequently used by commercial companies, but also has become a valuable tool in epidemiological research and public health planning. In this paper, we explore ethical issues in a project that “scrapes” public websites of U.S. county jails as part of an effort to develop a comprehensive database to enhance HIV surveillance and improve continuity (...) of care for incarcerated populations. We argue that the well-known framework of Emanuel et al. provides only partial ethical guidance for the activities we describe, which lie at a complex intersection of public health research and public health practice. We suggest some ethical considerations from the ethics of public health practice to help fill gaps in this relatively unexplored area. (shrink)

The article examines a number of methodological and conceptual features in the philosophical work of S.L. Rubinstein of the early (Marburg) period. It is assumed that the copies of Rubinstein’s doctoral inaugural dissertation available at the university of Marburg (Germany) and it the private archive of K.A. Abulkhanova represents two parts of one research, which understated expect in it’s first part (the text submitted for defense) an interpretation and criticism of Hegel’s absolute rationalism, and in the second part (...) an exposition of the author’s own concept. It is proved that Rubinstein overcomes the logical limitation the Hegelian philosophical absolutization – the opposition of being and consciousness, the author fuses object and subject in a single being as a domain of accommodation of both, the construction of the internal consistent picture of being as the actual being of a leaving subject.

Among the hidden treasures squirreled away in the archives of Israel’s National Library lies a fragmented correspondence that sheds new light on the afterlife of a project that was long deemed the farewell gift to the German language and culture from the remnants of its Jewry. It is an exchange of letters between two scholars, whose interest in the German rendition of the Bible occupied them for many years, first in Germany, and later in the land where Hebrew was vernacular (...) and where one might think there would no longer be a need for translations of the Bible; particularly not into a language that aroused considerable aversion in the aftermath of the war. And yet, the 1963–64 exchange between the two Jerusalemites, the Vienna-born and Frankfurt-crowned philosopher, theologian, and translator Martin Buber and the Riga-born, Berlin- and Marburg-educated biblical scholar Nechama Leibowitz tells a different story. It shows they both believed the project that began under the title Die Schrift, zu verdeutschen unternommen should be revised once again, after its completion so as to underline its ongoing relevance for present and future readings of the Bible tout court, in German and Hebrew speaking lands alike.

Western feminists, physicians, and ethicists condemn the traditional genital surgeries performed on women in some non‐Western cultures.

A speaker wishes to persuade a listener to take a certain action. The conditions under which the request is justified, from the listener’s point of view, depend on the state of the world, which is known only to the speaker. Each state is characterized by a set of statements from which the speaker chooses. A persuasion rule specifies which statements the listener finds persuasive. We study persuasion rules that maximize the probability that the listener accepts the request if and only (...) if it is justified, given that the speaker maximizes the probability that his request is accepted. We prove that there always exists a persuasion rule involving no randomization and that all optimal persuasion rules are ex-post optimal. We relate our analysis to the field of pragmatics. (shrink)

We suggest an equilibrium concept for a strategic model with a large number of players in which each player observes the actions of only a small number of the other players. The concept fits well situations in which each player treats his sample as a prediction of the distribution of actions in the entire population, and responds optimally to this prediction. We apply the concept to a strategic voting model and investigate the conditions under which a centrist candidate can win (...) the popular vote although his strength in the population is smaller than the strengths of the right and left candidates.  2003 Elsevier Inc.

Eye tracking is used to investigate human choice procedures. We infer from eye movement patterns in choice problems where the deliberation process is clear to deliberations in problems of choice between two lotteries. The results indicate that participants tend to compare prizes and probabilities separately. The data provide little support for the hypothesis that decision makers use an expected utility type of calculation exclusively. This is particularly true when the calculations involved in comparing the lotteries are complicated.

Despite its widespread existence, the adaptive role of aneuploidy (the abnormal state of having an unequal number of different chromosomes) has been a subject of debate. Cellular aneuploidy has been associated with enhanced resistance to stress, whereas on the organismal level it is detrimental to multicellular species. Certain aneuploid karyotypes are deleterious for specific environments, but karyotype diversity in a population potentiates adaptive evolution. To reconcile these paradoxical observations, this review distinguishes the role of aneuploidy in cellular versus organismal evolution. (...) Further, it proposes a population genetics perspective to examine the behavior of aneuploidy on a populational versus individual level. By altering the copy number of a significant portion of the genome, aneuploidy introduces large phenotypic leaps that enable small cell populations to explore a wide phenotypic landscape, from which adaptive traits can be selected. The production of chromosome number variation can be further increased by stress‐ or mutation‐induced chromosomal instability, fueling rapid cellular adaptation. (shrink)

We show that for solvable games, the calculation of the strategies which survive iterative elimination of dominated strategies in normal games is equivalent to the calculation of the backward induction outcome of some extensive game. However, whereas the normal game form does not provide information on how to carry out the elimination, the corresponding extensive game does. As a by-product, we conclude that implementation using a subgame perfect equilibrium of an extensive game with perfect information is equivalent to implementation through (...) a solution concept which we call guided iteratively elimination of dominated strategies which requires a uniform order of elimination.

A number of experts receive noisy signals regarding a desirable public decision. The public target is to make the best possible decision on the basis of all the information held by the experts.

In the second, each expert is also driven by a private motive: to have his recommendation accepted. We show that in the (...) first culture, every mechanism will have an equilibrium which does not achieve the public target, whereas the second culture gives rise to a mechanism whose unique equilibrium outcome does achieve the public target.

Influenza mandates in health care institutions are recommended by professional associations as an effective way to prevent the contraction of influenza by patients from health care workers.

This article examines this legal framework and draws important lessons from this litigation for health care institutions. (...)

This paper is an examination of some modelling problems regarding imperfect recall within the model of extensive games. It is argued that, if the assumption of perfect recall is violated, care must be taken in interpreting the main elements of the model. Interpretations that are inconsequential under perfect recall have important implications in the analysis of games with imperfect recall.

Neuroeconomics is examined critically using data on the response times of subjects who were asked to express their preferences in the context of the Allais Paradox. Different patterns of choice are found among the fast and slow responders. This suggests that we try to identify types of economic agents by the time they take to make their choices. Nevertheless, it is argued that it is far from clear if and how neuroeconomics will change economics.

The dilemma of responding to evidence: Should our models be judged according to experimental results? The dilemma of modelless regularities: Should models provide the hypothesis (...) for testing or are they simply exercises in logic that have no use in identifying regularities?

This article aims to support a proposal by Sloman that certain modal expressions, in particular, ought, in fact have a more pronounced comparative backbone than others . The connection between ‘ought’ and ‘better’ is supported by linguistic data and a proposal is advanced for modeling ideals in a way that makes room for non-comparative, strong, priority-type (...) necessity.

We develop a framework for modeling choice in the presence of framing effects. An extended choice function assigns a chosen element to every pair (A, f ) where A is a set of alternatives and f is a frame. A frame includes observable information that is irrelevant in the rational assessment of the alternatives, but nonetheless affects choice. We relate the new framework to the classical model of choice correspondence. Conditions are identified under which there exists either a transitive or (...) a transitive and complete binary relation R such that an alternative x is chosen in some (A, f ) iff x is R-maximal in the set A. We then demonstrate that the framework of choice correspondence misses information, which is essential to economic modeling and which is incorporated in the extended choice function. (shrink)
