Implementation of the Walrasian correspondence without continuous,convex, and ordered preferences

This paper consideres the problem of designing better mechanisms whose Nash allocations coincide with constrained Walrasian allocations for non-neoclassical economies under the minimal possible assumptions. We show that no assumprions on preferences are needed for feasible and continuous implementation of the constrained Walraisan correspondence. Further, under the monotonicity assumption, we present a mechanism that is completely feasible and continuous. Hence, no continuity and convexity assumptions on preferences are required, and preferences may be nontotal or nontransitive. Thus, this paper gives a somewhat positive answer to the question raised in the literature by showing that, even for non-neoclassical economies, there are incentive-compatible, privacy preserving, and well-behaved mechanisms which yield Pareto-efficient and individually rational allocations at Nash equilibria.I wish to thank J. S. Chipman, J. Jordan, M. Richter, H. Weinberger, the editor, and two anonymous referees for useful comments and suggestions. I am particularly thankful to L. Hurwicz who stimulated my interest in this problem and provided detailed comments and suggestions.     

Vicissitudes of the sacred

Conclusions Since the late 1960s and early 1970s, American sociologists have been made increasingly aware, mostly by Marxist and phenomenological critics, of the latent moral or practical implications of what often purports to be objectively impersonal scientific theories. Whereas Goffman's imaginative writing style and intensely personal observational technique never allowed him to be easily placed in the camp of the positivist objectivists, the profound moral issues and assumptions of his work, as Friedson's statement implied, never fully appeared in a clear light either, probably because of Goffman's strategic decision to accommodate his moral insights somewhat to the positivist intellectual milieu of the 1950s. The present analysis reveals, however, that, even more than allowing tacit moral assumptions to operate in the back-ground of his work, Goffman focussed centrally on an investigation of the various levels of moral understanding, a project for which he used the Book of Job as his signpost. Goffman's inquiry, it should be emphasized, was not conducted through an external observation of other people's consciousness but rather by means of an intensely personal reflection upon the governing frames of his own consciousness as it looked out upon the everyday social world. What we have chronicled in this essay is the dramatic evolution of Goffman's own moral consciousness, not the moral understandings of the subjects of his studies, the latter, of course, changing as Goffman's own moral understandings evolved. exact nature and purpose of his moral investigation. As we have seen, an ongoing reference for Goffman's moral inquiry was not a rationalist philosophical treatise, but rather one of the most poetic and profound narratives of the Bible, a work in which the radical mystery and transcendence of the Sacred, beyond all structures of nature, society, and the human ego, are asserted. The symbolic and narrative features of the Job text accord well with its emphasis on the mystery of Being, whose fundamental depth and power could not easily be compressed within the outlines of abstract rationalist propositions. Goffman, likewise, combines a final emphasis on the mystery of Being, beyond all finite frames and fabrications, with a pervasively symbolic and narrative style in his writing. In directing our attention toward the ultimate mystery of Being, of which finite frames provide only a tentative revelation, Goffman mounts an additional critique of Durkheim, not only for naively assuming that sacred representations must always reflect the social rather than the individual inclinations of human nature, but also for assuming that the social dimension of homo duplex alone serves as the ultimate and final reference for sacred forms. Much like contemporary existentialists who emphasize human finitude and the mystery of Being, Goffman uses Job's increasingly open psyche as his basis for understanding that beyond nature, beyond society, and beyond the individual lies a mystery of Being that continually surpasses, indeed itself engenders the ever-changing outlines of these other finite structures of existence. In the end, Goffman is perhaps more mythmaker than moralist, a religious poet who, for an age in which the traditional symbols of Being have been displaced by new cognitive forms, particularly those of science, magically transformed contemporary scientific language into archetypal symbols of the Sacred. Goffman's task was extremely difficult, one that would have strained the intellectual ingenuity and linguistic resources of a less talented man, namely the task of conveying to large numbers of relatively unprepared, deeply preoccupied and increasingly self-absorbed moderns a message about a completely unfashionable, economically useless and essentially ego-threatening mystery. Let us hope the large silence that now exists in his absence will not be filled by words less meaningful than his own.     

A quantitative theory of preferences: Some results on transition functions

We investigate a general theory of combining individual preferences into collective choice. The preferences are treated quantitatively, by means of preference functions (a,b), where 0(a,b) expresses the degree of preference of a to b. A transition function is a function (x,y) which computes (a,c) from (a,b) and (b,c), namely (a,c)=((a,b),(b,c)). We prove that given certain (reasonable) conditions on how individual preferences are aggregated, there is only one transition function that satisfies these conditions, namely the function (x,y)=x·y (multiplication of odds). We also formulate a property of transition functions called invariance, and prove that there is no invariant transition function; this impossibility theorem shows limitations of the quantitative method.Research supported in part by the National Science Foundation.     

Strong equilibrium outcomes of voting games ¶are the generalized Condorcet winners

We consider voting games induced by anonymous and top-unanimous social choice functions. The class of such social choice functions is quite broad, including every t-refinement of the Plurality Rule, Plurality with a Runoff, the Majoritarian Compromise and the Single Transferable Vote, i.e., any selection from either of these social choice rules which is obtained via tie-breaking among candidates according to any total order t on the set of alternatives. As announced in our title, the strong equilibrium outcomes of the voting games determined by such social choice functions turn out to be nothing but generalized Condorcet winners, namely the (n,q)-Condorcet winners. In the case of social choice functions (such as those just listed) which are furthermore top-majoritarian, they coincide with the classical Condorcet winners.The non-alphabetic ordering of names has a reason deserving to be explained. Murat R. Sertel, this man from the Bosphorus whose contributions put Turkey on the academic map of Economic Theory, passed away on January 25, 2003, while this paper was in print. His untimely death was met with deep sorrow by his colleagues, friends and students all over the world. Murat R. Sertel was one of the forerunners of the Age of Economic Design. He was a genuine scholar, brilliant intellectual, excellent teacher, beloved friend, a wonderful company, a devoted son and an affectionate father. May he rest in peace.¶The authors thank Semih Koray, Ipek Sanver, Fuad Aleskerov, Ahmet Alkan, Hakan Inal, Hervé Moulin, Bezalel Peleg, Robert Wilson, Muhamet Yldz and two anonymous referees for their helpful comments.

How epoch making are high technologies? The case of biotechnology

This paper is a commentary on the current tendency among sociologists to embrace the notion that high technologies will be revolutionary or epoch making. The implicit neo-Schumpeterian logic of these claims is detailed, and a preliminary framework for empirical examination is developed for the case of biotechnology. Available evidence suggests that biotechnology, because it will be applied primarily in declining sectors of the economy and is mainly a substitution technology, is unlikely to be an epoch-making technical form. The implications of these observations for sociological reasoning about new technologies and technological change are discussed.     

Why and how East Germans rebelled

Conclusion Attempts to explain the East German uprising are particularly significant because it was probably the most important event in the collapse of European communism. The building of the Berlin Wall was the symbol of the Cold War division between Eastern and Western Europe and its fall led to the reunification of Germany and marked the end of this European partition. Elizabeth Pond has written: When the Berlin Wall fell, the crash obliterated a country, an empire, and an era. There are several obstacles to adequate explanation, however. The reasons why East Germans rebelled cannot be separated from the end of communism in Europe. The GDR was imprisoned within the socialist bloc (similar to the way the SED locked up its own people). Rebellion could only (successfully) occur when Soviet domination had eased. The popular rebellion in East Germany was precipitated by a wave of exit unleashed by reform communists in Hungary who had eliminated border controls. The Wall was opened from outside before it was pulled down from within.Even when confined to the protests within the GDR, that is to the second stage of the revolt, the main causes of the uprising have often been misunderstood. The would-be exiters were an important part of voice and often prompted the activities of the pro-GDR opposition. Loyal voice did play a significant role in calling for and speaking at anti-regime rallies. But these oppositionists did not mobilize the population themselves. Mass exodus, and political reform elsewhere in Eastern Europe, had set off the revolt by giving many East Germans a new found sense of political efficacy that led them to act spontaneously. Without private advantages and aware of the personal risks, millions of ordinary citizens went onto the streets because they felt a collective sense of obligation to do so.The key to understanding how East Germans rebelled, that is, to explaining the distinctiveness of the revolt, is the ex-GDR's lack of national identity. While the Polish and Hungarian leaderships could initiate democratization and hope to protect some of their interests under postcommunist rule, the SED risked losing its state as well. Hirschman underestimates the GDR leadership's dilemma when he argues that the extinction of the German Democratic Republic can be seen as the ultimate penalty for the long suppression of exit and voice (p. 200). The GDR could only survive by preventing its citizens from leaving for the bigger, richer, and more democratic state in a divided nation. East Germany was inconceivable as a liberal state. Reform efforts always literally ran into the Wall.Not only does the lack of national identity explain the hardline nature of the regime, it also illuminates the revisionism of the opposition. It is only an apparent paradox that in a state without legitimacy the loyalty among the GDR intellegentsia was particularly intense. The same matter-of-fact nationalism that made many East Germans feel a part of the Federal Republic (of which they were, by nature of the West German Grundgesetz, virtual citizens), tied artists, writers, and oppositionists alike to the ideal of the better German state. They felt that the evils of German nationalism could best be preempted by socialism, which offered a clear anti-fascist position and justified the continued existence of the GDR. East Germans had to rebel against an unrelenting SED and then abandoned the pro-GDR opposition's hope for a rejuvenation of East Germany. Continued emigration and mounting protest doomed efforts to reform the regime and rescue the state. Elections had to be moved up from May to March 1990 to head off pending economic and political disaster. West German parties, which supported GDR affiliates, and Western politicians, who were well known and often better liked than their East German counterparts, played a dominant role in the campaign. The vote brought a conservative coalition to power that had promised the fastest and marginalized the two major opponents of immediate unity: the reformed communists (PDS) and the opposition alliance (Bündnis 90). Democratic transition had become part of German unification.

Yes-no voting

Yes-No (Y-N) voting is a voting method for choosing a governing coalition in a parliament after the seating of its members. Each member can designate a party to be Y (it must be included in the governing coalition), N (it must be excluded from the governing coalition), or neither (it may be either in or out of the governing coalition). The majority coalition acceptable to the most voters, because it includes all parties that these voters designate Y and no parties that they designate N, is given the first opportunity to form a government. Possible combinations of majority coalitions that a member might vote for are derived, including ones based on consistent and interval voting strategies. Examples illustrate a number of different phenomena, such as when a rational voter might not be loyal to his or her party by designating it Y.     

Explaining risky choices without assuming preferences

Economic theories of choice under uncertainty assume that agents act as if they have preferences which govern their choices between risky options. Theories differ as to the exact specification of the preference structure, but it is common to assume that preferences are complete and satisfy certain consistency requirements such as transitivity and monotonicity. In this paper, it is argued that there may be reason to doubt whether individuals act as if they have complete and consistent preferences over risky actions. Instead it is suggested that individuals should be thought of as actively constructing preferences through a process which I call rationalisation. It is then argued that rationalisation provides a basis for understanding certain experimentally observed anomalies which appear quite at odds with conventional theory.     

Triangular empathy: “The other” in psychotherapy with individuals

This paper seeks to explore triangular dimensions in individual psychotherapy. In addition to serving as the dyadic object of transference projection and/or as selfobject for a person in psychotherapy, the therapist may be called upon to help the patient work on relationships with certain early, important people or their representations and on the interplay between such relationships and the therapeutic one, that is, in a triangular configuration. Because patients' attempts to introduce others into individual psychotherapy are sometimes experienced by therapists as resistant rather than as integral to the therapeutic process, I propose an empathic reconsideration of such patient efforts to get us to help with the complicated dimensions of human relatedness.     

The Impact of Assessment Procedures on the Relationship between Paper and Pencil and Behavioral Indicators of Social Skill

This study investigated the relationship between paper and pencil measures and molecular behavioral indicators of social skills in three widely used assessment options. A total of 221 students engaged in either a get acquainted or role play interaction, in which they were given instructions and knew they were being observed. A third group engaged in a waiting period interaction, in which they were given no instructions to interact and had no knowledge of being observed. Results showed that subjects in the get acquainted and role play situations scored higher on several measures of social skills than those in the waiting period situation. In addition, there was most variability in the measures of social skills in the waiting period situation. In general, trait measures exhibited poor correspondence with behavioral measures of social skills in all situations. However, state paper and pencil measures of social skills exhibited strong correspondence with behaviors in the waiting period, but not in the get acquainted or role play situations. Implications for the assessment of social communication skills through commonly used assessment procedures are discussed.     

“Come, Join Our Family”: Discipline and Integration in Corporate Organizational Culture

This article critically examines primaryprocesses and effects of the so-called neworganizational culture that is organized on theprinciples and practices of Total Quality Management(and its variations) and increasingly practiced incorporate organizations in the 1990s. The paperspecifically analyzes the effects of the organizationalcultural practices of family and"team" on the employee and discusses their role incorporate discipline, integration, and control. Data aredrawn from field research conducted in a largemultinational corporation and the analyses andinterpretive propositions are informed by a critical socialpsychoanalytic perspective. The paper disputes theconventional view that the practices of the "newculture" and its purported reform of thehierarchical, specialized, conflict-ridden workplaces oftraditional industrial organizationsempower employees and providemeaningful relationships in the workplace.It is argued, on the contrary, that these new designer culturalpractices serve as processes of regulation, discipline,and control of employee subject selves.     

When All That Is Solid Melts Into Language: Judith Butler and the Question of Matter

Judith Butler's analysis of corporeal matters offers an exemplary account of the hidden political agenda within the very grain of representation and discourse. This essay, however, argues that language and its political implications are even more complex and curious than Butler concedes. The author contests the conflation of writing with Culture, as if Culture is the constitutive and enclosed space of productivity and transformation. She argues that the question of Nature has not been provoked in Butler's analysis but answered and dismissed much too quickly. The author extends the problematic of writing to biology and suggests that Nature is literate.     

Viewing Telephone Therapy Through the Lens of Attachment Theory and Infant Research

This article discusses the use of the telephone for psychotherapy and applies basic tenets of attachment theory and research on infant development to understand the therapy process. Clinical case examples of four models of attachment (secure, insecure ambivalent, insecure avoidant, disorganized) illustrate diverse patient capacities to use the telephone during a planned 10-week break from ongoing, in-person treatment. It is suggested that telephone therapy may be variously effective based on the attachment system that becomes activated due to the separation, and patients with insecure avoidant or disorganized attachment patterns may have more difficulty managing the alternative treatment modality.     

A Cultural Perspective on the Study of Chinese Adolescent Development

This paper argues that the dominant Western construction of adolescent development which defines adolescence as an individuation process with the primary theme of developing an autonomous self is alien to the Chinese cultural system. In contrast to the Western conception of an autonomous self based on separation from others and self-other differentiation, the Chinese conception of self is more complicated. Based on the Chinese-West differences, the paper argues that the borrowed Western concept of self and the Western models do not appear to fit Chinese adolescents' experience. A concept of self-in-relational-network is therefore proposed for understanding the unique developmental processes and outcomes of Chinese adolescents.     

Fairness,the veil of ignorance and social choice

A point of departure for this study is the recognition that various individuals may have different opinions about the exact form a social welfare function should have. To obtain some kind of amalgamation of differing individual social preferences, a modified version of the Rawlsian veil of ignorance is used and a definition of social efficiency suggested and analysed. A socially efficient state is defined by means of endogenous and individual veils of ignorance and, in addition, the Pareto principle. Efficiency may be described as a situation where individuals with similar social preferences constitute subsocieties in an optimal manner. Furthermore, a state is fair if it is (socially) efficient and equitable. An extension of the concept of fairness, called weak fairness, is also suggested. The analysis in this study does not presuppose any objective interpersonally comparable measure of utility.I would like to thank Professor Gevers, editor of this journal, and two anonymous referees for valuable comments on this paper.

Play grounds

The author discusses the ambience presented by casinos to their customers. He explores the issues of space as an attraction to people being brought into casinos for the purpose of play and the compatibility of the casino's internal design with the concept of welcoming space and its degree of legibility: how well a first time visitor can read the activities and opportunities within its spaces.     

The direct social preference relation in the theory of public expenditure

It is shown that if there is a finite number of private goods, a single public good, and the individual preferences satisfy certain monotonicity and separability conditions then there is a unique and complete social preference relation defined on the set of allocations by the requirement that the relation is individualistic in terms of the individual ordinal preferences. This relation, called the direct social preference relation, is derived without imposing interpersonal welfare comparisons and all its ordinal properties are inherited directly from those of the individual preferences. However, an allocation which is maximal in terms of the direct social preference relation on the set of feasible allocations is in general not Pareto optimal and the relation may therefore not be suitable as a guide to optimizing social choice.This version of the paper has benefitted from J. Weymark's insightful and detailed comments. In addition, valuable suggestions have been received from G. C. Archibald, C. Blackorby, D. Donaldson and D. Primont.

The “Homo Sapien Genetic Survival Trait”

An explanation was sought for the reason that minorities immigrating to the USA have difficulty getting along with each other or with the majority. Worldwide an explanation was sought for the reason that nations that break up, break up along ethnic group or cultural lines. The answer for both questions appears to be an assumed survival mutation early in the development of Homo sapien to create a Genetic Survival Trait. This requires most Tribal members, as defined here, to give their primary allegiance to their Tribe and not to the USA, and to support a drive for Tribal independence. Recommendations are made for developing improved training methods in the USA to reduce this problem.     

Paradigm Warriors: Regress and Progress in the Study of Contentious Politics

Paradigm warfare is a well-worn way of engaging in the polemics of research, but it frequently reduces paradigms to caricatures and turns complex reports of empirical research into cartoons. This is illustrated by two one-sided accounts of the Chiapas rebellion: one based on a simplistic political opportunity cartoon and the other on a foreshortened culturalist one. Reducing the many-sided (and in some ways ambiguous) approaches of the political process model to a supposedly hegemonic paradigm neglects many substantive contributions and cuts with too broad a stroke at social movements while ignoring the many-branched contributions of research and theory on contentious politics.     

Sexual mate-swapping: A comparison of “normal” and “clinical” populations

While the results of research by sociologists and psychologists indicate that sexual mate-swapping is not a pathological behavior, psychodynamic considerations suggest that mate-swappers may have had difficulty adequately completing the developmental tasks of adolescence. Large scale surveys support this speculation in that mateswappers recall more unhappy childhood experiences and extremes of either parental overprotectiveness or neglect than do matched populations of non-mate-swappers. The researcher hypothesized that mate-swapping may represent an attempted solution to long standing individual and/or marital problems resulting from these earlier difficulties. An exploratory study of six mate-swapping couples in marital therapy supported the researcher's speculation that mate-swapping among a client population should be viewed from both a sociological and psychodynamic perspective. Further studies are needed to ascertain to what extent individual personality factors influence the choice of mate-swapping among the general, non-client population.
