DOES FINANCE ALTER THE RELATION BETWEEN INEQUALITY AND GROWTH?

This paper introduces a model in which greater inequality reduces growth in economies with low levels of financial development but that this effect is attenuated in economies with more developed systems. The model also predicts that individuals in economies with developed financial markets have a higher tolerance to inequality. Using a panel dataset that covers a large number of countries, this paper shows empirical evidence that is consistent with the main predictions of the model. Overall, this paper's major findings highlight that some of the pernicious effects of inequality can be attenuated by improving access to credit. (JEL D3, E6, P1, O4, I2)     

Conservation Management of EU Priority Habitats after Collapse of Traditional Pastoralism: Navigating Socioecological Transitions in Mountain Rangeland

Agricultural abandonment is a major driver of change in rural landscapes. Assumed to provide beneficial results to the environment and the conservation of biota, rural abandonment triggers landscape and biotic homogenization and loss of valuable species and habitats. This article focuses on the ecological effects and conservation challenges of shifts in extensive grazing regimes on marginal pastureland of Mediterranean mountains. We conceptualize a navigated socioecological transition toward conservation‐oriented management after the collapse of historical land systems. The article provides examples from the LIFE+ project “Higro,” developed in mountainous protected areas in Portugal, of how management for conservation could sustain disturbance‐dependent habitats. We argue that actively and regularly managing large habitat areas should be envisaged as a short‐term approach to limit the immediate effects of rural abandonment. A gradual integration of conservation targets with other activities in changing rural economies is necessary to foster long‐term conservation of species and habitats, building on the link between conservation‐oriented habitat management and ecosystem services in rural landscapes. Conservation goals should run alongside recovery of social systems and innovation applied to traditional sources of income. This parallel development would contribute to building up social‐ecological resilience by maintaining a diversity of social and ecological capital in rural areas.     

Conflicto,Identificacion y Poder en la Influencia Minoritaria

En 6 condiciones experimentales se presenta a los sujetos un texto minoritario extremamente favorable al aborto, siendo evaluada la influencia en una dimensión directa (actitud frente al aborto) y en una dimensión indirecta (actitud frente a la contracepción). En tres condiciones se introduce una pequeña amenaza y en las otras tres una fuerte amenaza que implica un fuerte costo social simbólico en caso de un eventual acuerdo con la minoría. En cada caso, o bien no se explica ninguna identificación (condiciones control) o bien se lleva a los sujetos a percibirse identificados ya a la Iglesia ya a la minoría. Los resultados principales muestran que a) en las condiciones sin identificación explícita, la minoría obtiene el efecto de conversión esperado por el modelo de la influencia minoritaria, en el caso de que el costo social es elevado; b) por el contrario, en caso de identificación explícita con la minoría el costo social disminuye tanto la influencia indirecta como la directa, lo que aboga en defensa del modelo del poder; c) en las condiciones en las que los sujetos son identificados con la Iglesia aparece un curioso efecto: cuanto mayor es el costo social más se acercan los sujetos a la minoría. Dado que las explicaciones divergen según la interpretación que los autores dan de este efecto paradójico y del conjunto de los resultados, se presentan dos interpretaciones complementarias, incluso aunque se contradigan entre ellas.     

Qui donnera effet à la convention du travail maritime de l'OIT, 2006?

La convention du travail maritime, 2006, qui entrera en vigueur le 20 août 2013, regroupe des dizaines de normes de l'OIT adoptées depuis les années 1920. Elle a été décrite comme le «quatrième pilier» de la réglementation internationale maritime, aux côtés de trois grandes conventions de l'OMI sur la sécurité en mer et la prévention de la pollution marine. Selon les auteurs, le défi consistera à l'appliquer au moyen des mécanismes réglementaires existants, soit la mise en ?uvre par l'Etat du pavillon et le contrôle par l'Etat du port. Techniquement, la responsabilité repose sur les premiers, mais la prolifération des pavillons de complaisance donne à penser que ces derniers joueront également un rôle crucial, tout comme, dans ces deux cas, la formation des inspecteurs.     

LATIN AMERICAN IMMIGRATION TO SPAIN

On the whole, Latin American migration currently represents the highest percentage of migration into the Spanish state. This situation results from a series of factors, combined in both the points of origin and destination, and relating to the economic policies of the emitting and receiving countries within the framework of globalization. However, despite the way in which the phenomenon is portrayed by politicians and the media, this predominance is not due exclusively to the historical and cultural ties between Latin America and Spain, but rather to the implementation of a complex series of legal measures which contribute to the constant renewal of national collectives at the service of the labour markets in search of the desired ‘flexibility’ based on ethnic and gender segmentation of migrant workers.     

A modified DEA model to estimate the importance of objectives with an application to agricultural economics

This paper demonstrates a connection between data envelopment analysis (DEA) and a non-interactive elicitation method to estimate the weights of objectives for decision-makers in a multiple attribute approach. This connection gives rise to a modified DEA model that allows us to estimate not only efficiency measures but also preference weights by radially projecting each unit onto a linear combination of the elements of the payoff matrix (which is obtained by standard multicriteria methods). For users of multiple attribute decision analysis the basic contribution of this paper is a new interpretation in terms of efficiency of the non-interactive methodology employed to estimate weights in a multicriteria approach. We also propose a modified procedure to calculate an efficient payoff matrix and a procedure to estimate weights through a radial projection rather than a distance minimization. For DEA users, we provide a modified DEA procedure to calculate preference weights and efficiency measures that does not depend on any observations in the dataset. This methodology has been applied to an agricultural case study in Spain.     

Ecological,Groundwater, and Human Health Risk Assessment in a Mining Region of Nicaragua

The objective of the present study was to integrate the relative risk from mercury exposure to stream biota, groundwater, and humans in the Río Artiguas (Sucio) river basin, Nicaragua, where local gold mining occurs. A hazard quotient was used as a common exchange rate in probabilistic estimations of exposure and effects by means of Monte Carlo simulations. The endpoint for stream organisms was the lethal no‐observed‐effect concentration (NOECs), for groundwater the WHO guideline and the inhibitory Hg concentrations in bacteria (IC), and for humans the tolerable daily intake (TDI) and the benchmark dose level with an uncertainty factor of 10 (BMDLs_0.1). Macroinvertebrates and fish in the contaminated river are faced with a higher risk to suffer from exposure to Hg than humans eating contaminated fish and bacteria living in the groundwater. The river sediment is the most hazardous source for the macroinvertebrates, and macroinvertebrates make up the highest risk for fish. The distribution of body concentrations of Hg in fish in the mining areas of the basin may exceed the distribution of endpoint values with close to 100% probability. Similarly, the Hg concentration in cord blood of humans feeding on fish from the river was predicted to exceed the BMDLs_0.1 with about 10% probability. Most of the risk to the groundwater quality is confined to the vicinity of the gold refining plants and along the river, with a probability of about 20% to exceed the guideline value.     

THE PRIVATE AND FISCAL RETURNS TO SCHOOLING IN THE EUROPEAN UNION

We present estimates of the private and fiscal returns to schooling in 14 European Union countries. Estimates of the private returns to post‐compulsory formal education take into account the effects of schooling on wages and employment probabilities and allow for academic failure rates, the direct and opportunity costs of education, and the impact of personal taxes, social security contributions, and unemployment and pension benefits on lifetime earnings. Estimates of fiscal returns capture the long‐term effects of a marginal increase in average educational attainment on public finances under conditions that approximate general equilibrium.

Macroeconomic Determinants of Equilibrium Unemployment Insurance

This paper proposes a new modeling strategy as regards the definition of an optimal level of unemployment benefits. While the traditional methodology privileges labor market equilibrium to derive optimal employment, wage and unemployment benefit levels, we present a model in which the optimal level of unemployment benefits is a function of the government’s macroeconomic objectives in terms of inflation and output fluctuations. In a second stage, the model allows for the investigation of unemployment insurance effects on labor market equilibrium.     

Deviance Residuals for an Angular Response

This paper discusses deviance residual approximations in von Mises regression models. By using a relationship between the von Mises and the wrapped normal distributions, the paper shows that the deviance component of the von Mises distribution is approximately a linear function of the standard normal distribution. Two standardized forms are proposed for the deviance residual, and a simulation study is performed to compare the approximation of the proposed residuals to the standard normal distribution. An illustrative example is given.
