Julio Dávila 《Economic Theory》1997,10(3):483-495
Summary. In this paper, I study the existence of Sunspot Equilibria in a general framework whose dynamics allow for the presence of
predetermined variables in the system. The main motivation for this research comes from the fact that previous studies did
not allow for such predetermined variables which, nevertheless, appear quite naturally in economic models. I show, for a non-negligible
subset of dynamics with predetermined variables verifying usual assumptions, the existence of Stationary Sunspot Equilibria
fluctuating between an arbitrary finite number of states arbitrarily close to a steady state.

Michel Bélanger 《Journal of Consumer Policy》1989,12(3):333-342
Today, international health law and international consumer law are developing in the same direction and with much interaction. But the developments are not uniform. As international health law takes consumer protection into account, it tends to increase the gap between a Western international law and a Third World international law, and to emphasize the negative harmonization approach towards international health protection.Another problem concerns the unification of the rules of international health law and those of international consumer law. This problem is particularly difficult to solve, as the rules of international consumer law themselves are still far from being unified.

Internationales Gesundheitsrecht und Verbraucherautonomie
Zusammenfassung Internationales Gesundheitsrecht und internationales Verbraucherrecht entwickeln sich heute in gleicher Richtung, obwohl sie anderen Quellen entspringen. Die wechselseitige Durchdringung nimmt zu, auch wenn die Enwicklung nicht einheitlich vor sich geht. Je mehr das internationale Gesundheitsrecht den Verbraucherschutz in sich aufnimmt, destomehr trennt es sich in ein Recht für entwickelte Staaten und ein solches für Dritte Welt-Länder. Ein vorwiegend negativ-abwehrender Zugang herrscht vor.Ein anderes Problem beinhaltet die Harmonisierung der Regeln des internationalen Gesundheits- und des internationalen Verbraucherrechts. Dies ist schon deshalb schwer erreichbar, weil das Verbraucherrecht selbst nicht einheitlich vorgeht. Die Probleme verschärfen sich, wenn man — ohne eine internationale Verbraucherinstitution wie die WHO — eine gemeinsame positive Gesundheitspolitik für Verbraucher erreichen will.

In search of the meaning of entrepreneurship 总被引:9,自引:0,他引:9
This paper is an attempt to build a bridge between the popular and the academic usage of the terms entrepreneur and entrepreneurship, and to identify the raw materials needed to construct an interpretive framework capable of illuminating the nature of entrepreneurship and its role in economic theory. We review briefly the contributions made to this topic by Cantillon, Schumpeter, Schultz and Kirzner. We advance a synthetic definition of the entrepreneur as someone who specializes in taking responsibility for and making judgemental decisions that affect the location, the form, and the use of goods, resources, or institutions. We then conclude with some observations on the basic choice confronting economics regarding the place of entrepreneurship in economic analysis. 相似文献

We examine the two traditions of content analysis: the first in which one substitutes words of a text with categories, and the second in which one looks for clusters of words that may refer to a theme. In the first tradition, preexisting dictionary categories give meaning to the words; in the second, meaning comes after the fact. Preexisting dictionary categories (the substitution model) are calibrated instruments applied within experimental designs that leave no space for doubt; meanwhile, the ability of the correlational model to conjure up complex themes from fragments of a text yields no unique solution. These differences have bearings on the production of new social knowledge. We expound on the epistemological foundations of the two traditions of interpretation and draw from them decision rules upon which one may rely for choosing among appropriate content-analytic tactics. Two reasons make this essay timely and critical: (1) the increasing variety of new content-analyticsoftware for particular purposes and (2) the almost exclusive focusing on software and technology at the expense of adjusting the choice of the software to the nature of the text. Two studies, one in historiometry, the other in autobiography, illustrate the liabilities and benefits of the two models of content analysis. 相似文献

There is general agreement that attitudes towards the entrepreneur, entrepreneurial activity, and its social function are determinant factors for university students to decide an entrepreneurial career.This empirical study aims at assessing and comparing the attitudes of university students towards entrepreneurship and enterprise formation in Catalonia and Puerto Rico, using a sample of 837 and 435 students, respectively.Results reveal a positive entrepreneur’s image. Both samples have a favorable perception of desirability of new venture creation, although the perception of feasibility is by far not so positive and only a small percentage has the firm intention to create a new company. 相似文献

This research proposes an approach to measure hospital performance based on a generalization of Banker and Morey (1986) and Førsund (1996). This approach considers quasi-fixed inputs explicitly, calculates their implicit cost, and quantifies returns to scale. The performance measure is decomposed into allocative and technical inefficiencies. Based on a very complete data set of Québec hospitals, we find that significant inefficiencies of up to 17% ($700 CAN million) could have been saved through improved performance. Postestimation analyses that include qualitative measures of care suggest that differences in performance are attributable to differences in management or unobservable quality of care rather than patient case mix. 相似文献

J. Castellano-Paulis A. Hernández-Mendo Verónica Morales-Sánchez M. T. Anguera-Argilaga 《Quality and Quantity》2007,41(1):93-104
We present a probabilistic model based on the one developed by Hernández Mendo and Anguera (Revista de Psicologíca Social,
16(1), 71–93, 2001). Here we have tried to break down the interaction contexts that the opposing teams are able to generate
and transform during the game. We are aware that a given player or team does not produce consistent behaviour in similar situations.
However, a degree of uncertainty is assumed to exist regarding whether the results obtained are a specific function of the
analysis used. In order to carry out this research a category system which optimized that used in the previous model was developed.
This system should enable the interaction between teams to be observed within the actual play of a soccer game. A lag sequential
analysis was performed on the basis of a coding of the behavioural flow. After describing the behavioural patterns obtained
a probabilistic model of the development of play in soccer is proposed. 相似文献

This paper presents a logit model for dating business-cycle turning points. The regressors are monthly series from the Business
Cycle Indicators database of the Conference Board. Dividing the sample period into a subset for model initialization (1959∶9–1970∶12)
and a subset for testing (1971∶1–2003∶12) yields a chronology that is nearly identical to that established by the National
Bureau of Economic Research (NBER). However, the recognition lag is less than four months, in contrast to an average of more
than eleven months for the official chronology. (JEL E320)

This work draws on consumer and psychology research to explain sociocognitive aspects of product-market dynamics at a higher
level of specificity than prior research. The authors extend the field’s understanding of market-shaping shared knowledge
through a theory-informed discussion of how shared product knowledge comes to exist and how it changes as product markets
develop. They define shared knowledge as the aspects of product representations that are common across the minds of market
actors, making it possible for them to understand one another. The authors also discuss ways to track shared knowledge content
that is expressed in market narratives. As the characteristics of shared knowledge are explained and linked to stages of product-market
development, the authors develop a set of researchable propositions to guide future research. The theoretical arguments and
propositions in this article complement extant marketing strategy research by integrating individual-level consumer theory
with market evolution models.
