The dynamics of remittance behaviour among Senegalese men and women in Spain

This article explores the conditions under which Senegalese immigrants in Spain send remittances home, beginning with the premise that remittances are intertwined with migration histories and migrants’ incorporation into host societies. Given the strong gender norms in Senegal, we perform separate analyses for men and women. We use a longitudinal approach to analyse how remittance behaviour is affected by immigrants’ characteristics, their economic integration, and their ties to origin and destination. Our data come from the MAFE and MESE surveys, which were implemented in 2008 and 2011, respectively. The results indicate that remitters constitute a clear majority among Senegalese immigrants in Spain. The Kaplan–Meier analysis shows that they rarely stop remitting once they start doing so, and the multivariate analysis reveals a strong positive association between employment and remittance sending. Although most coefficients in the full model are similar for men and women, some important differences emerge as well.     

DISENFRANCHISEMENT IN LINGUISTICALLY DIVERSE SOCIETIES: THE CASE OF THE EUROPEAN UNION

We consider a linguistically diversified society and examine the notion of language disenfranchisement when some individuals are denied the full access to documents and political process in their native tongues. To calculate the disenfranchisement indices we use the Dyen percentage cognate matrix of linguistic distances between Indo‐European languages and apply survey and population data on language proficiency in the European Union. We then determine optimal sets of official languages that depend on society's sensitivity against disenfranchisement and comprehensiveness of the chosen language regime. We also discuss the language situation in the European Union after its last enlargement. (JEL: D70, O52, Z13)     

An Experiment on Rational Insurance Decisions

We describe the results of an experiment on decision making in an insurance context. The experiment was designed to test for the underlying rationality of insurance consumers, where rationality is understood in usual economic terms. In particular, using expected utility as the preference function, we test for positive marginal utility, risk aversion, and decreasing absolute risk aversion, all of which are normal postulates for any microeconomic decision context under uncertainty or risk. We find that there the discrepancy from rational decision making increases with the sophistication of the rationality criteria, that irrationality concerning fair premium contracts is uncharacteristically high, and that the slope of absolute risk aversion seems to depend on the format of the insurance contract. This revised version was published online in June 2006 with corrections to the Cover Date.     

Convergence criteria for interval-valued inequality indices

In this paper we introduce an interval-valued inequality index for random intervals based on a convex function. We show that if this function does not grow faster than x ^p , then the inequality index is continuous on the space of random intervals with finite p-th moment. A bound for the distance between the inequality indices of two random intervals is also constructed. An example is presented to motivate and illustrate the developments in this paper.     

Automatic Specification Testing for Vector Autoregressions and Multivariate Nonlinear Time Series Models

This article introduces an automatic test for the correct specification of a vector autoregression (VAR) model. The proposed test statistic is a Portmanteau statistic with an automatic selection of the order of the residual serial correlation tested. The test presents several attractive characteristics: simplicity, robustness, and high power in finite samples. The test is simple to implement since the researcher does not need to specify the order of the autocorrelation tested and the proposed critical values are simple to approximate, without resorting to bootstrap procedures. In addition, the test is robust to the presence of conditional heteroscedasticity of unknown form and accounts for estimation uncertainty without requiring the computation of large-dimensional inverses of near-to-singularity covariance matrices. The basic methodology is extended to general nonlinear multivariate time series models. Simulations show that the proposed test presents higher power than the existing ones for models commonly employed in empirical macroeconomics and empirical finance. Finally, the test is applied to the classical bivariate VAR model for GNP (gross national product) and unemployment of Blanchard and Quah (1989 Blanchard, O. and Quah, D. 1989. “The Dynamic Effects of Aggregate Demand and Supply Disturbances,”. The American Economic Review, 79: 655–673. [Web of Science ®] , [Google Scholar]) and Evans (1989 Evans, G. W. 1989. “Output and Unemployment Dynamics in the United States: 1950–1985,”.

Expanding economic protection to the elderly in Latin America

This article addresses the reforms introduced in Latin American pension systems that had the aim of increasing coverage beyond formal‐sector workers. For this purpose, fourteen representative regional experiences are analysed using a taxonomy based on features of the cases examined in terms of design, implementation and results. The findings show that, although the reforms share the goal of expanding coverage, there are significant differences deriving from the context in which they were originally designed, their goals, and the capacity available to implement them. The results are not homogeneous, and it is possible to identify some aspects in which policy decisions can lead to better or worse results.     

Do healthy diets in Europe matter to the environment? A quantitative analysis

Final consumption of food products figures amongst the strongest contributors to negative environmental impacts in Europe, with the production of beef and pork at agricultural level being the main responsible part of the food supply chain. This article analyses quantitatively the environmental impact of changing European diets. The environmental impact of European consumption is determined with an environmental extended input-output analysis, supplemented by a partial equilibrium model reflecting changes of the agricultural sector to modified diets. It results that agricultural production does not decrease significantly in reaction to reduced food consumption, due to a changed trade balance and substitution effects.     

Coalitional Interval Games for Strategic Games in Which Players Cooperate

We propose a method to associate a coalitional interval game with each strategic game. The method is based on the lower and upper values of finite two-person zero-sum games. Associating with a strategic game a coalitional interval game we avoid having to take either a pessimistic or an optimistic approach to the problem. The paper makes two contributions to the literature: It provides a theoretical foundation for the study of coalitional interval games and it also provides, studies, and characterizes a natural method of associating coalitional interval games with strategic games.      

Analysis of the response structure to a set of questions with large number of scale points: a new combined metric and categorical approach

In the field of social sciences, certain tasks, such as the identification of typologies and the characterization of groups of individuals according to a set of questions, tend to pose a challenge for researchers. Further complications arise if the chosen rating scale is from 0 to 10, since the responses can be treated either as metric or categorical variables. This paper shows that neither treatment is able on its own to capture all the inherent properties of this type of data, and goes on to propose a bicriteria clustering approach, which captures both perspectives and enables the simultaneous analysis of mixed data using multiple tables.
