Mixed Motives of Simultaneous-move Games in a Mixed Duopoly: Comments and Erratum
Get PDFIf the public and private firm have mixed motives about payoff in a simultaneous-move game, Choi (2006) analyzes that the resulting equilibrium turns out to be an inefficient level with the monopoly of private firm even if there are Nash equilibria. However, we find that if we use equilibrium profit, we would have solved its unique Nash equilibrium that both firms aim to maximize the relative payoffs.Mixed Duopoly
Cournot-Bertrand competition in a unionized mixed duopoly
Get PDFWe investigate a differentiated mixed duopoly in which private and public firms can choose to strategically set prices or quantities by facing a union bargaining process. For the case of a unionized mixed duopoly, only public firm is able to choose a type of contract based on the degree of substitutability in the equilibrium. Focusing on the case of substitute goods, we show that Bertrand (respectively, Cournot) competition entails higher social welfare than Cournot (respectively, Bertrand) competition if the degree of substitutability is relatively
small (respectively, large). Thus, there are multiple Nash equilibria in the contract stage of the game. As a result, Singh and Vives' ranking of social welfare is reversed in a range of substitution values for which it is a dominant strategy for public firm to choose either quantity or price contracts
Privatization, Government's Preference and Unionization Structure: A Mixed Oligopoly Approach
Get PDFBy introducing the government's preference for tax revenues into the theoretical framework of unionized mixed oligopolies, this study investigates the efficiency of privatization. The results show that (i) regardless of the government's preference for tax revenues, its incentive to privatize a public firm depends on the number of the private firms and (ii) social welfare can decrease with an increase in the number of firms depending on the level of government's preference for tax revenue. Moreover, if the number of private firms and the government's preference for tax revenue are sufficiently small, then social welfare under a unionized privatized oligopoly is greater than under a unionized mixed oligopoly while the government has an incentive not to privatize the public firm, and vice versa if only the number of firms is sufficiently large
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
Mixed Motives of Simultaneous-move Games in a Mixed Duopoly
Get PDFThis paper investigates the simultaneous-move games in a mixed duopoly where firms are maximizers of either profits or relative profits. Contrary to previous results, if each firm has mixed motives about payoff in a simultaneous-move game, a private firm monopolizes whereas the public firm produces nothing.
Conformism, peer pressure and adverse selection
No full textTo examine the effects of peer pressure in adverse selection problem, we define a peer pressure function that represents the psychological costs and incorporate it into the agent's utility function. Based on these assumptions, the efficient agent who has conformity preference produces less outputs than the first-best level, while the inefficient agent produces more than the second-best level of standard adverse selection output when the agents feel peer pressure among themselves. Although the production gap between the utility functions under peer pressure narrows, the gap of the ex post information rent goes wider as the information rent of efficient agents increases. Our theoretical results are consistent with some empirical/experimental findings.
Cournot and Bertrand competition with asymmetric costs in a mixed duopoly
Get PDFWe investigate a differentiated mixed duopoly in which private and public firms can choose to strategically set prices or quantities when the public firm is less efficient than the private firm. Thus, regardless of whether the goods are substitutes or complements, if the degree of public firm's inefficiency is sufficiently small, there exists a dominant strategy for both public and private firms that choose Bertrand competition, while there exists a dominant strategy only for the private firm that chooses Bertrand competition if the degree of inefficiency is sufficiently large. Consequently, we show that regardless of the nature of goods, (i) social welfare under Bertrand competition is determined in equilibrium, if the degree of public firm's inefficiency is sufficiently small; and (ii) if the degree of its inefficiency is sufficiently large, social welfare under which the private firm sets its price and the public firm sets its quantity is determined in equilibrium. Moreover, the ranking of a private firm's profit is not reversed.Inefficiency, Cournot-Bertrand Competition, Mixed Duopoly
