Racial beliefs, location and the causes of crime
No full textThe aim of this paper is to show that both location and stereotype racial beliefs matter for explaining the high criminality rate among blacks in cities. In our model, blacks and whites are identical in all respects. However, if, for no economic but for extrinsic reasons, every-body (including blacks) believes that blacks are more criminals than whites, then we show that blacks (for rational reasons) become more criminals than whites, earn lower wages and reside in ghettos located far away from legal activities. There is a vicious circle in which blacks cannot escape because both location and labor market outcomes re-inforce each other to imply high crime rates among blacks living in cities. In this context, we show that a transportation policy that subsidizes the ‘access’ to legal activities for blacks can lead to a sharp decrease in their crime rate
Beyond the Melting Pot: Cultural Transmission, Marriage, and the Evolution of Ethnic and Religious Traits
No full textThis paper presents an economic analysis of the intergenerational transmission of ethnic and religious traits through family socialization and marital segregation decisions. Frequency of intragroup marriage (homogamy), as well as socialization rates of religious and ethnic groups, depend on the group's share of the population: minority groups search more intensely for homogamous mates, and spend more resources to socialize their offspring. This pattern generally induces a dynamics of the distribution of ethnic and religious traits which converges to a culturally heterogeneous stationary population. Existing empirical evidence bearing directly and indirectly on the implications of the model is discussed
A model of cultural transmission, voting and political ideology
No full textIn this paper, we present a model of cultural transmission of preferences on goods, some of which are provided publicly through simple majority voting. We emphasize the existence of a two-way causality between socialization decisions and political outcomes. This generates the possibility of indeterminacies and multiple self-fulfilling equilibrium paths in cultural change and politics. We provide then a rationale for ideologies and collective socialization institutions as coordination mechanisms allowing cultural groups to preserve or shift political power in favor of their preference profile in the long run
On the cultural transmission of preferences for social status
No full textWe study the formation of preferences for ‘social status' as the result of intergenerational transmission of cultural traits. We characterize the behavior of parents with preferences for status in terms of socialization of their children to this particular cultural trait. We show that degenerate distributions of the population (whereby agents have either all status preferences or all non-status preferences) are dynamically unstable. Moreover, under some conditions, there exists a unique stationary distribution which is non-degenerate (in which both status and non-status preferences co-exist in the population), and this distribution is locally stable. Finally, we study the dependence of the stable stationary distribution of status preferences on institutional, technological and policy parameters which affect agents' economic conditions
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
