A note on selecting maximals in finite spaces
Given a choice problem, the maximization rule may select many alternatives. In such
cases, it is common practice to interpret that the final choice will end up being made by
some random procedure, assigning to any maximal alternative the same probability of
being chosen. However, there may be reasons based on the same original preferences
for which it is suitable to select certain maximal alternatives over others. This paper
introduces two choice criteria induced by the original preferences such that maximizing
with respect to each of them may give a finer selection of alternatives than maximizing
with respect to the original preferences. Those criteria are built by means of several
preference relations induced by the original preferences, namely, two (weak) dominance
relations, two indirect preference relations and the dominance relations defined with the
help of those indirect preferences. It is remarkable that as the original preferences
approach being complete and transitive, those criteria become both simpler and closer to
such preferences. In particular, they coincide with the original preferences when these
are complete and transitive, in which case they provide the same solution as those
preference
A non-proposition-wise variant of majority voting for aggregating judgments
Majority voting is commonly used in aggregating judgments. The literature to date on judgment
aggregation (JA) has focused primarily on proposition-wise majority voting (PMV). Given a set of issues
on which a group is trying to make collective judgments, PMV aggregates individual judgments issue by
issue, and satisfies a salient property of JA rules—independence. This paper introduces a variant of
majority voting called holistic majority voting (HMV). This new variant also meets the condition of
independence. However, instead of aggregating judgments issue by issue, it aggregates individual
judgments en bloc. A salient and straightforward feature of HMV is that it guarantees the logical
consistency of the propositions expressing collective judgments, provided that the individual points of
view are consistent. This feature contrasts with the known inability of PMV to guarantee the consistency
of the collective outcome. Analogously, while PMV may present a set of judgments that have been
rejected by everyone in the group as collectively accepted, the collective judgments returned by HMV
have been accepted by a majority of individuals in the group and, therefore, rejected by a minority of
them at most. In addition, HMV satisfies a large set of appealing properties, as PMV also does. However,
HMV may not return any complete proposition expressing the judgments of the group on all the issues at
stake, even in cases where PMV does. Moreover, demanding completeness from HMV leads to
impossibility results similar to the known impossibilities on PMV and on proposition-wise JA rules in
genera
Building and Using Models as Examples
Sometimes, theoreticians explicitly state that they consider their models as examples. When this is not the case, it is fairly common for theoreticians to attribute to their models the characteristics and objectives of illustrative examples. However, this way of understanding models has not received enough attention in the methodological literature focused on economics. Given that didactic examples and their properties are extremely familiar in practice, considering theoretical models as examples can offer a useful perspective on models and their properties. On the basis of both explanatory and exemplifying role played by the deductive arguments by which results are proved, the paper emphasizes also the importance of understanding in theoretical work, the analogical and tentative character of the application of models, the central role played by the above mentioned arguments in such application, the didactic function of theory, and the transmision of plausibility from those arguments to the results obtained.models; examples; explanatory arguments; theoretical understanding; analogical application
A pooling approach to judgment aggregation
The literature has focused on a particular way of aggregating judgments: Given a set of yes or no
questions or issues, the individuals’ judgments are then aggregated separately, issue by issue.
Applied in this way, the majority method does not guarantee the logical consistency of the set of
judgments obtained. This fact has been the focus of critiques of the majority method and similar
procedures. This paper focuses on another way of aggregating judgments. The main difference is
that aggregation is made en bloc on all the issues at stake. The main consequence is that the
majority method applied in this way does always guarantee the logical consistency of the
collective judgments. Since it satisfies a large set of attractive properties, it should provide the
basis for more positive assessment if applied using the proposed pooling approach than if used
separately. The paper extends the analysis to the pooling supermajority and plurality rules, with
similar result
Papernomics. Sciences as Games and Means of Censorship / Papernomics. Ciencias y juegos como medios de censura
Las revistas son básicamente el único canal a través del cual los científicos pueden dar a conocer el resultado de su investigación a sus colegas. Las revistas científicas seleccionan la información que publican y garantizan su calidad por medio de un procedimiento de censura por pares de doble ciego. Si, por un lado, este procedimiento parece lógico como método para incluir un estudio en un campo científico consolidado, también es verdad que puede funcionar como mecanismo de censura. La idea de que los trabajos no incluidos en una publicación estándar carecen a priori de prácticamente ningún valor es la base de la carrera académica. Partiendo de este principio se ha construido entre los investigadores un sistema jerárquico de clasificación. La base de este currículum científico es la métrica de la vanidad.Palabras claveRevistas científicas, currículum, censura. AbstractThe journals are basically the only channel through the scientists can make the result of their research known to their colleagues. Scientific journals select the information they publish and guarantee its quality by means of a double blind procedure of censorship by peers. If on the one hand this procedure seems logical as a method for including a study within a consolidated scientific field, it is also true that it can function as a mechanism for censorship. The idea that the works not included in a standard publication lack a priori of practically any value is the basis of the career of academic scholars. Starting with this principle, a hierarchical system of scientific ranking has been built among researchers. The basis of his scientific curriculum is the metric of vanity.Key WordsScientific journals, curriculum, censorship
"Flatus vocis". Genealogía de una palabra sin sentido: patrimonio
En este trabajo se analiza la génesis de la palabra “patrimonio”, tal
y como se utiliza actualmente en el Mundo Occidental. Se concluye que
puede haber dos modelos de “cultura” (término que cae en desuso, al ser
sustituido por la palabra “patrimonio”), aquél en que ésta se compone de una
serie de obras de diferentes tipos que cada sociedad integra en su sistema
de valores morales y políticos. Y, en segundo lugar, otro modelo de cultura
en el que esas obras quedan descontextualizadas y pasan a ser exportables
e incluso adquiribles comercialmente. Éste sería el modelo actual, en el que
la palabra “patrimonio” sustituye al antiguo término “cultura” y en el que
ese término pasa a designar un supuesto conjunto de bienes destinados al
consumo turístico.In this work an analysis is made of the word “heritage”, as it is
now used in the West World. The conclusion is that there are possibly two
models of “culture” (term fallen into disuse being replaced by the word
“heritage”), one in which this is composed of a series of works of different
kind that each society incorporates into its system of moral and political
values. And secondly, another model of culture in which those works
are descontextualized and become exportable and even commercially
acquirable. This would be the present model, where the word “heritage”
replaces the old term “culture” and where that term stands for a supposed
set of goods intended for the tourist use
Protection of traditional knowledge from an economics perspective
El artículo se centra en la propuesta de protección de los conocimientos tradicionales
(CCTT) plasmada en los documentos elaborados por la secretaría del Comité Intergubernamental
sobre Propiedad Intelectual y Recursos Genéticos, Conocimientos Tradicionales y Folclore, de la
Organización Mundial de la Propiedad Intelectual. En un primer momento, se destacan los rasgos
de esa propuesta de protección que pueden resultar más determinantes desde el punto de vista
económico. En segundo lugar, se analiza cómo pueden desarrollarse los distintos tipos de
intercambios bajo esa protección. Respecto de los intercambios en los que la transferencia
de conocimientos desempeña un papel destacado, el artículo subraya los problemas de
asimetrías informativas que pueden operar en contra de los intereses de las comunidades.
De donde se desprende que puede ser muy conveniente por lo general que las comunidades
cuenten con algún apoyo externo, preferentemente público. Respecto de los intercambios de
productos derivados de los CCTT se argumenta que otras medidas de desarrollo más directas
que la protección pueden ser más efectivas. Y se subraya la ayuda que los signos distintivos
como las marcas colectivas, las denominaciones de origen protegidas y las indicaciones
geográficas protegidas pueden prestar. En una sección posterior, se compara, contraponiéndolas,
la orientación y justificación de la protección propuesta en la documentación mencionada con
la visión que la Economía del Bienestar ofrece de la propiedad intelectual e industrial. El
artículo finaliza sugiriendo que, no obstante lo anterior, el proceso de internacionalización del
sistema de la propiedad intelectual e industrial puede justificar, por razones de reciprocidad,
medidas o sistemas de protección de los CCTTThis article focuses on the proposal of the protection of traditional knowledge expressed in
documents prepared by the Intergovernmental Committee on Intellectual Property and Genetic
Resources, Traditional Knowledge and Folklore, of the World Intellectual Property Organisation.
Firstly, the characteristics of this protection proposal that could result in more determining
factors from an economics point of view are highlighted. Secondly, an analysis is made of how
the different types of exchanges covered by this protection may be developed. As regards the
exchanges in which the transfer of knowledge plays an important role, the article underlines
the problems of informational asymmetry that can work against the interests of the community.
From where it emerges that it may be generally more advisable that the communities have
some external, preferably public, support. As regards exchanges of products arising from
traditional knowledge, it is argued that the protection may be more effective by other more
direct means. The help of distinctive signs, such as collective marks, is underlined, as well as
protected denominations of origin, and protected geographic indications that may be used. In a
later section, a comparison is made by contrasting the orientation and justification of the
protection proposal in the previously mentioned documents with the justifi cation that Welfare
Economics offers to intellectual and industrial property. The article ends by suggesting that,
notwithstanding the aforementioned, the internationalisation process of the intellectual and
industrial property may justify, for reasons of reciprocity, measures or protection of traditional knowledgeEste trabajo ha sido realizado en el marco del proyecto FONCICYT 95255, titulado ‘Conservación, desarrollo, aprovechamiento social y protección de los conocimientos y recursos tradicionales en Méxic
