Multiple Equilibria in the Welfare State
Full text linkExcess distortions in the welfare state might be the consequence of the government's lack of ability to commit not to help "unlucky" agents. Incentive considerations that are crucial in standard insurance in the presence of moral hazard, plays no role in this case. As a consequence, the government might provide too much insurance. Still, equilibria with incomplete insurance and above-minimum effort might arise. Two possible reasons for multiple equilibria are explored in the paper, namely that marginal utility of consumption is positively associated with effort and that economic policy is costly. It is shown that the equilibria can be Pareto rankable. Borrowing analytical tools from recent developments in dynamic games (Matsui and Matsuyama, 1995), stability conditions of different equilibria are analyzed.
Survey Evidence on Wage Rigidity: Sweden in the 1990s
Full text linkWe present the results from a repeat survey on wage rigidity in a sample of 159 Swedish firms, conducted during a prolonged period of very high unemployment and very low inflation. We document the virtual absence of wage cuts, and trace this pervasive nominal rigidity to a set of interacting factors, including the legal status of the wage contract, the structure of bargaining institutions, and the design of social insurance. But employees’ concerns about fairness and relative wages also appear to play an important role. In addition, we report new results on underbidding, efficiency wage mechanisms, and unemployment persistence.Nominal wage rigidity; Panel data; Recession; Effort models; Unemployment persistence
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
