Cost raising strategies in a symmetric, dynamic duopoly
No full textThis paper provides a characterisation of the set of dynamic models in which symmetric duopolists have incentives to raise their common cost. The dynamic analysis has two advantages over existing static models. First, it avoids conceptual weaknesses, allowing conjectures to be derived endogenously rather than imposed. Secondly, it extends the conditions (restrictive in static models) under which symmetric cost raising is profitable. The model is illustrated by standard examples from industrial organisation (quantity and price adjustment, and learning-by-doing)
Compatibility between differentiated networks
No full textThis paper develops a generalised model of network competition when consumers vary in their preferences for network size and location, and networks are vertically and horizontally differentiated. The effect of compatibility on the degree of competition between the networks is analysed. Two effects are identified as central to determining networks' incentives towards compatibility. Compatibility decreases vertical differentiation (and hence increases competition); but it also decreases the importance of market share (and so decreases competition). Which effect dominates depends on the relative importance of horizontal and vertical aspects in consumers' utilities. When network size is a relatively important factor in consumers' utilities, neither the larger nor smaller network in the unique asymmetric equilibrium wishes to be compatible. When horizontal aspects are important, both networks wish to be compatible. For intermediate cases, the larger network does not wish to be compatible, in contrast to the smaller network. The model may explain the dynamics of network industries, particularly interconnection agreements between Internet service providers
The effects of uncertainty on optimal consumption
No full textWhen marginal utility is convex and there is pure labour income uncertainty, certain results are well-known. Asset return uncertainty is often assumed to have qualitatively similar effects; see e.g. Skinner (1988). We show that this assumption is not correct. Asset return uncertainty gives rise to an additional term in the Euler equation, which by introducing a role for current cash-in-hand, may work in the opposite direction to the precautionary motive, leading to ambiguity in the slope of the expected consumption time profile. We present a linearised version of the Euler equation, and an associated closed form solution, in order to provide intuition for these results. Numerical analysis indicates that the approximation is reasonable for empirically plausible estimates of the variances of the underlying disturbances
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
