Limited Attention as a Scarce Resource in Information-Rich Economies
Get PDFThis article uses basic facts from the psychology of attention to show how the limited attention of consumers affects economic competition. The article determines endogenously whether an economy is information rich or information poor. A conventional economic equilibrium results if subjects have spare attention capacity. At the positive level, the respective impacts of advances in information technology, international integration and the media on equilibrium diversity and level of attention-seeking activities are shown. At the normative level, the issues of welfare, efficiency and optimal policy interventions are addressed. Copyright � The Author(s). Journal compilation � Royal Economic Society 2008.
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
On understanding economic reality at the beginning of the twenty-first century: an essay in remembrance of Professor Laski
No full textEconomic objects are objects which are produced by employing inputs and valued by applying a valuation procedure. In a market economy the valuation is performed by the price mechanism. Ideally market prices reflect the scarcity values corresponding to individual preferences. This article argues that new technologies and business models call the separation of production and valuation into question and thereby challenge the theoretical foundation of the market economy. In particular the finance and data industry turns beliefs and preferences from exogenous individual characteristics into produced objects. As a result, at the beginning of the twenty-first century economic activity shifts from the production of objects to the production of values and prices. The paper adopts a classical perspective and uses the production and reproduction scheme to outline a model of the smart economy. A smart economy is an Internet-based economy which employs (artificially intelligent) robots to produce sensor-enabled objects via which the behavior of consumers can be tracked and directed. The robots are owned by capital-owners who employ agents for developing the robots, designing data-based devices and business models, managing them, and financing them. The owners and their agents employ workers to complement robots and to provide personal services. The paper proposes investing more into the production and reproduction of consumer sovereignty, active citizenship, and the res publica, in order to avoid a dystopic brave new world. The author sketches an agenda for the maintenance and renewal of the institutions of a free and democratic society by confronting the smart economy with core concepts of European enlightenment: secularization, constitution and rule of law, separation of powers, nation state, education, and market order
In search of economic reality under the veil of financial markets
Get PDFThis paper presents a general equilibrium model with technological uncertainty, financial markets and imperfect information. The future consists of uncertain environments that are more or less clearly distinguishable (measurable). This limits the possibilities of specialization and diversification. Households have no direct information about the productivity of risky technologies. They rely on the information conveyed by the set of financial products provided by the financial sector, the pay-off promises of the products and their prices. Unreliable information-processing by financial markets leads to deception of households. As a result, extending the space spanned by financial products is not unambiguously good. This suggests a policy rule which ties financial innovations to the experience base of the economy
