European industrial districts: Influence of geographic concentration on performance of the firm

This paper reviews ideas and insights from recent firm strategy literature. We argue that these perspectives can be usefully extended to explain the competitive advantage of the industrial district. Most of the empirical studies seeking evidence of the competitive advantage of the industrial district consisted of case studies. This paper attempts to offer a measurement of the performance of industrial district firms on a comparative basis by using the case of the Spanish ceramic tile industry.     

Not in the eyes of the beholder: envy among Bolivian migrants in Spain

This article explores a culturally sensitive topic, envy, among Bolivian migrants in Spain. Following a constructivist approach to emotions, we examine discourses of envy, as they are shaped by the cultural contexts in which they emerge. Our study uses a sample of 30 transnational households and multi-sited ethnography to illustrate the ways emotions and their effects on sociality serve as a mechanism of social control, especially when the boundaries of such a community have been stretched transnationally. Envy is an important component of a belief system central to understanding the emergence, or lack thereof, of trust and solidarity among migrants and can shape the types of social relations and conflicts between migrants and non-migrant households back in Bolivia. These conflicts have been exacerbated by economic instability, high unemployment rates and precarious wages especially for the undocumented migrant community in Spain.     

ON THE POSSIBILITY OF INFORMATIONALLY EFFICIENT MARKETS

This paper presents conditions for a resolution of the Grossman–Stiglitz paradox of informationally efficient markets. We display a market with asymmetric information where a privately revealing equilibrium obtains in a competitive framework and where incentives to acquire information are preserved as long as the correlation in traders’ valuations is not too large. The equilibrium is efficient, and the problems associated with fully revealing rational expectations equilibria are precluded without resorting necessarily to noise traders. The robustness of the results to general information structures is established and the effect of market power is examined in a large market approximation to the competitive economy. The model is applied to explain changes in bidding behavior in central bank liquidity auctions in the crisis period. (JEL: D82, D84, G14, E59)     

Modeling the impact of social discrimination on the physical and mental health of Portuguese gay,lesbian and bisexual people

Background: Despite growing acceptance of same-sex sexuality in Portugal, identity development of lesbian, gay and bisexual (LGB) individuals is still restricted by negative societal attitudes, which maintain the experience of stigmatization and discrimination. The purpose of this study is to document the frequency of discriminatory events experienced by sexual minorities and their association with indicators of physical and mental health in Portugal. Methods: A total of 610 LGB participants completed an online survey (mean age?=?34.48, SD?=?11.54). Most participants were single and self-identified as gay (73.8%). The survey included five categories of survey items: demographic information, social support, physical health, mental health, and discrimination experiences. Results: Physical and mental health results revealed that bisexual people were more likely to report higher levels of psychological distress than gay men. Overall, between one-fifth and one-fourth of the participants in this sample frequently felt the need to hide their sexual orientation to prevent discrimination experiences across the different settings. Regarding actual discrimination experiences, close to 20% reported having suffered from verbal abuse, followed by close to 10% who suffered from written threats, harassment, and physical threats. A hierarchical multiple regression analysis was performed to assess the effects of anticipated and actual discrimination on mental health. Possible confounding variables were added in the first block – age, sexual orientation, being in a relationship, body mass index, and HIV status. Anticipated and actual discrimination experiences were added in the second block. The first block of the analysis explained 6% of the overall variance, while the second block – discrimination experiences – explained an additional 17%. Conclusion: Portuguese culture and stigma/discrimination create discriminatory experiences which impact LGB people's health. Unless policies are changed to allow for the acceptance of LGB people, they will continue to experience violence and discrimination as a result of homophobia.     

Hyperconsciousness of Race and Its Negation: The Dialectic of White Supremacy in Brazil

Brazilian social relations—their practices and their representations—are marked by a hyperconsciousness of race. Such hyperconsciousness, while symptomatic of how Brazilians classify and position themselves in the life world, is manifested by the often vehement negation of the importance of race. This negation forcefully suggests that race is neither an analytical and morally valid tool, nor plays a central role in determining Brazilian social hierarchies. The hyperconsciousness/negation of race dialectic allows us to understand how a system that is on the surface devoid of racial awareness is in reality deeply immersed in racialized understandings of the social world. To approach the hyperconsciousness/negation of race conundrum, I review pertinent Brazilian and United States bibliography focusing on problems associated with the racial democracy myth, and utilize ethnographic data and interpret newspapers articles reporting on one of the many events of police corruption and brutality in Rio de Janeiro.     

A Bayesian cluster analysis of election results

A Bayesian cluster analysis for the results of an election based on multinomial mixture models is proposed. The number of clusters is chosen based on the careful comparison of the results with predictive simulations from the models, and by checking whether models capture most of the spatial dependence in the results. By implementing the analysis on five recent elections in Barcelona, the reader is walked through the choice of the best statistics and graphical displays to help chose a model and present the results. Even though the models do not use any information about the location of the areas in which the results are broken into, in the example they uncover a four-cluster structure with a strong spatial dependence, that is very stable over time and relates to the demographic composition.     

Networks Matter: Male Mexican Migrants’ Use of Hospitals

Using the behavioral model for health care use and unique data from the Mexican migration project, we explore the factors associated with hospital use among Mexican male migrants to the US. Twenty-eight percent of the respondents reported receiving healthcare from a hospital. In addition to established enabling factors of time in the US and English language ability, this research points to the importance of family social networks as enabling hospital health care use among migrants. Migrants with more ties to family members with migration experience have an increased likelihood of using emergency room healthcare. The research adds to the body of literature by providing evidence that ties to individuals with US migration experience increases migrants’ probability of accessing healthcare at hospitals.     

Gini Index Decomposition for the Case of Two Subgroups

In the framework of inequality measures decompositions, this article introduces an immediate and straightforward simplification for the Gini index when a population is divided in two subgroups. Since one of the key points in inequality analysis is represented by the role of overlapping units, a simulation study is developed in order to analyze the effects of the overlapping component on inequality decomposition. Simple expressions for the measurement of either overlapping component and inequality between are derived, which allow to correctly evaluate and compare the effects of different factors on total inequality.
