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.     

The Effect of a Family Policy Reform on Mother’s Pay: A Natural Experiment Approach

All parents in Norway with children aged one to three, who do not attend publicly subsidised day care, are entitled to a cash-for-care (CFC) subsidy. Studies have shown that the reform has reduced mothers labour supply. In this paper we analyse wage effects of the reform. We put forward a framework for evaluating reforms when reforms are uniformly and equally accessible nation-wide. First, running a simple Difference in differences (DD) analysis, results suggest that the CFC reform has reduced the mothers wages. However, after controlling for the age of the child effect, by running a triple difference approach, we no longer find any evidence of negative wage effects.This revised version was published online in May 2005 with corrections to the authors name and to the heading of table A2.     

Muddying the Waters Does Not Have to Entail Erosion: Ecological Feminist Concerns with Purity

Ecofeminists call attention to the associations that have been made between woman and nature, which can operate as a source of both subjugation and resistance, exploitation, and inspiration. This paper expands upon feminist critiques of purity by phrasing these concerns in an ecological feminist perspective. This theoretical exercise of problematizing the ideal of purity sheds light upon the intersections of human and nonhuman oppression. Preservationist work has tended to employ the logic of purity by focusing on protection of the purity of the wild regions of the earth from the polluting forces of humanity. However, such approaches retain the troublesome nature/culture dualism. The author illustrates how attempts to fragment and radically separate people from the environment can prove to be highly dangerous. She connects the theoretical resistance to purity to the important activist work that is being done to expose environmental racism. Finally, she discusses how muddying the waters and resisting the logic of purity can offer a promising approach to pressing problems revolving around the intersections of human and nonhuman oppression.     

Choice,freedom, and freedom of choice

This paper argues in favour of a distinction between freedom and freedom of choice – a distinction that economists and political philosophers have so far either ignored or drawn wrongly. Drawing the distinction correctly may help to resolve a number of disputes in contemporary political philosophy and non-welfarist normative economics regarding the so-called preference-based account of freedom and the relevance, to judgements about freedom, of degrees of similarity between agents options. The paper begins by setting out three much discussed axioms for the measurement of freedom (of choice?) originally put forward by Pattanaik and Xu. It is suggested that the problems these axioms give rise to can be solved by distinguishing correctly between freedom and freedom of choice. The paper then sets out definitions of freedom, choice and freedom of choice, justifying these in philosophical terms and arguing their superiority to alternative definitions. Finally, on the basis of these definitions and with reference to Pattanaik and Xus axioms, it is shown that an agent can enjoy freedom without enjoying freedom of choice, and that she can enjoy an increase in one of these without enjoying an increase in the other.

Head movement during listening turns in conversation

In five subjects, head movement during conversation was monitored by polarised light goniometry, and recorded alongside speech and a signal proportional to peak amplitude of sound waves (peak loudness). Kinematic properties of listeners' head movements, such as amplitude, frequency and cyclicity, differentiated various conversational functions. That is, they were function-specific: symmetrical, cyclic movements were employed to signal yes, no or equivalents; linear, wide movements anticipated claims for speaking; narrow linear movements occurred in phase with stressed syllables in the other's speech (ynchrony movements); and wide, linear movements occurred during pauses in the other's speech. That, it is argued, bears upon the relation between thesignalling of communicative intentions and the synchronisation of interactional rhythm. Thus, the former appears to determine the timing and tempo of responses such as yes and no, while the latter determines the regulation of synchrony movements. The manner in which these factors interact in other conversational functions and their theoretical implications are discussed.     

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.     

Non-welfaristic theories of justice: Is “the intersection approach” a solution to the indexing impasse?

Rawls (1971, 1993) suggests that a primary goods index should be the basis for interpersonal comparisons in a theory of justice, but it is well known that in general this approach is not compatible with the Pareto principle. This is the indexing impasse. Sen (1985, 1991) argues that this is partly due to the fact that the approach does not take note of the citizens orderings of these bundles of valuable objects. He suggests an intersection approach, which is an incomplete approach to interpersonal comparisons based on judgements that are shared implications of the relevant set of weighting schemes. In this paper, we show that the intersection approach does not provide any solution to the indexing impasse. Unless the individuals have identical preferences, the intersection approach is incompatible with the Pareto principle. This paper originates from the second chapter of Brun (1998). An earlier version was presented at a conference on Non Welfaristic Issues in Normative Economics at the University of Caen in June 1999, and we should like to thank the participants at the conference for their discussion of the paper. Moreover, we are grateful to Geir B.Asheim, Alexander Cappelen, Kåre P.

The coming revolution of biotechnology: A critique of Buttel

Frederick Buttel was one of the pioneers in studying the social impacts of biotechnology, claiming originally that it will involve profound changes in social structure. Recently Buttel turned around his argument proposing that, rather than revolutionary, biotechnology is more a substitutionist technological form to be applied to declining sectors of the economy than an epoch-making technology. This paper provides both external and internal critiques of Buttel's new position based on the concept of the third technological revolution, looking at the impact of new technologies as a global and interrelated phenomenon, and not on an individual case-by-case basis. The concluding section suggests the necessity of bringing into the analysis those living in the Third World: 60% of this population lives from agriculture and will be affected by the deployment of agricultural biotechnologies, whether through substitutionism or through totally new products.     

Assessing success and decisiveness in voting situations

In this paper we propose a simple model for measuring success or decisiveness in voting situations. For an assessment of these features two inputs are claimed to be necessary: the voting rule and the voters behavior. The voting rule specifies when a proposal is to be accepted or rejected depending on the resulting vote configuration. Voting behavior is summarized by a distribution of probability over the vote configurations. This basic model provides a clear common conceptual basis for reinterpreting different power indices and some related game theoretic notions coherently from a unified point of view.The authors would like to thank to M.

The Ethnographic Turn: Fact,Fashion, or Fiction?

Commentators have suggested that a qualitative turn occurred in the social sciences in the last couple of decades of the twentieth century. We examine evidence on publication patterns, finding that the ethnographic turn consisted more of a proliferation of specialty journals than increased publication in mainstream sociology journals. This difference is important because it moves methodological debate inside the community of qualitative scholars, changing the focus from a contrast between qualitative and quantitative methods to questions about the relative merits of different styles of ethnographic work. Thus far, our data suggest, the main effect of the ethnographic turn may have been to institutionalize a set of labels rather than a set of practices.     

Addiction to fruit machines: A preliminary study among young males

Although most sources treat gambling as an adult phenomenon, adolescent gambling is more widespread than is generally recognized, and in some cases may even be pathological. This paper outlines a preliminary study of eight adolescents addicted to playing and gambling on coin-in-the-slot machines (more commonly known as fruit machines). Factors involved in the onset of fruit machine playing are examined along with their alternative gambling activities and associated problems. The role of skill and excitement components in persistent playing are also discussed.The author would like to thank the United Kingdom Economic and Social Research Council for funding this work through a research studentship.     

Brief Communications: Treating Problem Gamblers: A Residential Therapy Approach

The Gordon House Association (GHA) is the UK's only specialist and dedicated residential facility for problem gamblers. This paper describes the GHA therapeutic programme which is centred round a nine-month period of residency. Progression through the programme is described by overviewing each of the phases. These are initial assessment and five distinct phases comprising coping with today (Phase One), coping with yesterday (Phase Two), coping with change (Phase Three), coping with tomorrow (Phase Four), and coping on my own (Phase Five). These phases are themselves underpinned within the GHA core therapeutic approach which is also described.     

Qualitative immediacy and the communicative act

Qualitative immediacy (also termed quality in its philosophical sense and esthetic quality) is of fundamental importance within the pragmatic conception of meaning as interpretive act, and yet it has been virtually ignored by social scientists. The concept is traced through its foundations in Peirce's philosophy, its development in Dewey's theory of esthetic experience, and its relation to the general pragmatic conception of the self. The importance of the I in Mead's view of the self is seen as similar to Firstness in Peirce and esthetic experience in Dewey. Those turning to qualitative approaches ought to consider qualitative immediacy as a genuine addition to our understanding of human communication.I am grateful for helpful comments from Milton Singer, Kevin McMurtrey, Benjamin Lee, and Thomas Buckley, and for an opportunity to discuss this paper in the seminar on dialogue at the Center for Psychosocial Studies, Chicago.

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.     

Nonbinary social choice for economic environments

Assume a finite integer l2 and a social choice correspondence mapping each (p, Z) into a nonempty subset (p, Z) of Z, where p is a profile of individual preferences and Z is a set of outcomes of cardinality l or more. Suppose that satisfies Arrow's choice axiom, independence of infeasible alternatives, and the Pareto criterion. If the preference domain is the family of profiles of classical economic preferences over the space of allocations of public goods, then is dictatorial.I am grateful for some especially helpful comments by Jerry Kelly, John Weymark, and two anonymous referees.

Non-government development organisations and the grassroots in Peru

This paper examines the long-term grassroots empowerment strategies endorsed by non-governmental development organisations (NGDOs) in Lima, Peru and their application in concrete development programmes. An examination of NGDO literature and projects permits the synthesis of three ideal-typical empowerment strategies (Neo-Marxist, Neo-Anarchist, Coalition-Building). These strategies are described and compared, especially with respect to their diverging conceptions on processes of botton-up development, the characterisation of grassroots mobilisation and the role of the state and political parties. These differences, however, tend to be compromised once actual advocacy work with the grassroots is contemplated, when development projects have to deal with the micro-mobilisation patterns of the poor and the political conjuncture. Several interpretations of the contradiction between idealtypical strategies and actual advocacy tactics are discussed, concluding that such contradictions are inherent to any political process based on grassroots empowerment and a bottom-up agenda.     

On Being a White Person of Color: Using Autoethnography to Understand Puerto Ricans' Racialization

This article uses autoethnography to make larger conceptual/theoretical points about racial/ethnic identity categories for Puerto Ricans in the United States. I utilize Puerto Rican-ness to illustrate the limitations of U.S. race and ethnic constructs by furthering racialization analyses with seemingly contradictory categories such as white and people of color. I contrast personal experiences to those of racial/ethnic classificatory systems, the American imagery of Puerto Ricans, and simplistic, political identifications. Travel, colonial relations, intra-ethnic coalitional possibilities, and second-class citizenship are all aspects that expand on the notion of racialization as classically utilized in sociology and the social sciences. Although this is not a comparative study, I present differences between racial formation systems in Puerto Rico and the U.S. in order to make these points.     

Only sane: Autistic barriers in “boring” patients

This paper addresses needs of patients whom Winnicott called boring. Although often functioning well in the work world, they lack a rich inner life and a capacity for intimacy. Thus, psychotherapy is particularly problematic for them. To develop a model for working with this group of patients, the authors elaborate the concept of autistic barriers from British object relations theory, and suggest a changing role for the therapist in four successive phases of the treatment.     

“Marrying off” children as a developmental stage

Conclusion Marrying off the children is an important developmental stage in adulthood. Part of the very long and complex stage described by Erik Erikson as Generativity vs. Stagnation, this stage, like many earlier life stages, can be understood to give rise to a normative adult crisis that is destabilizing and anxiety-provoking. The marriage of one's offspring requires an ongoing transformation of parental narcissism, part of a developmental process that is intrinsic to parenthood. Issues of selfesteem are revived and reworked during this period. Traditional theory looks to oedipal rivalry or drive conflict of some kind to explain the anxiety at this time. An expanded understanding of narcissism, provided by Kohut and Elson has given us a broader view of these phenomena.The experience of hurt and sadness at a time when there is reason to celebrate can be a profoundly lonely and bewildering experience. As informed clinicians we can alleviate some of the loneliness and guilt about these feelings by understanding the challenge to the self that the marriage of adult children may represent.     

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.
