Redistribution, selection, and trade
2017
Abstract This paper examines the distributional effects of international trade in a general equilibrium model with heterogeneous agents and a welfare state redistributing income. The redistribution scheme is financed by a progressive income tax and gives the same absolute transfer to all individuals. Ceteris paribus, international trade leads to an increase in income per capita but also to higher income inequality on two fronts. Inter-group inequality between managers and workers increases, and intra-group inequality within the group of managers goes up as well. We show that for a given tax rate, there is an endogenous increase in the size of the welfare state that works against the increas…
Job Mobility and Sorting: Theory and Evidence
2019
Abstract Motivated by the canonical (random) on-the-job search model, I measure a person’s ability to sort into higher ranked jobs by the risk ratio of job-to-job transitions to transitions into unemployment. I show that this measure possesses various desirable features. Making use of the Survey of Income and Program Participation (SIPP), I study the relation between human capital and the risk ratio of job-to-job transitions to transitions into unemployment. Formal education tends to be positively associated with this risk ratio. General experience and occupational tenure have a pronounced negative correlation with both job-to-job transitions and transitions into unemployment, leaving the r…
Assessing the performance of the Latin American and Caribbean banking industry: Are domestic and foreign banks so different?
2015
AbstractThis paper studies the relative performance of domestic and foreign banks in the Latin American and Caribbean banking industry. Data Envelopment Analysis is used to compute technical efficiency scores for the years 2001 and 2013. Our main contribution is twofold. On the one hand, we assess performance at the level of the management of specific production factors. On the other hand, we distinguish program efficiency from managerial efficiency, which allows us to evaluate whether the differences in technical efficiency between national and foreign banks are due to the use of different technologies (program efficiency) or, conversely, differences in the managerial capacities of manager…
A naïve approach to speed up portfolio optimization problem using a multiobjective genetic algorithm
2012
a b s t r a c t Genetic algorithms (GAs) are appropriate when investors have the objective of obtaining mean-variance (VaR) efficient frontier as minimising VaR leads to non-convex and non-differential risk-return optimisation problems. However GAs are a time-consuming optimisation technique. In this paper, we propose to use a naive approach consisting of using samples split by quartile of risk to obtain complete efficient frontiers in a reasonable computation time. Our results show that using reduced problems which only consider a quartile of the assets allow us to explore the efficient frontier for a large range of risk values. In particular, the third quartile allows us to obtain efficie…
Bioenergy chain building: a collective action perspective
2014
Depletion of natural resources has become a key issue on the European policy agenda. Bottom-up measures have emerged in several countries with a view to promoting awareness campaigns and environmental sustainability, with the agenda set by individuals who start up collective initiatives at the local level. Such collective action provides an incentive to free-ride on the contribution of others. Social norms and the consequent behavior of individuals involved in collective action assume a key role in ensuring sustainable use of a public good, achieving significant, long-lasting success. The present study aims to ascertain which determinants most affect farmers’ willingness to contribute to co…
INSTRUMENTOS DE PROMOCIÓN DE LOS VINOS EN LOS RESTAURANTES DE ALTO NIVEL
2009
RESUMENEn los últimos años, la comercialización de vinos está adquiriendo un peso creciente en los establecimientos de restauración. El aumento en la complejidad de la oferta de vinos determina que la elección del consumidor esté condicionada por la oferta presente en la carta y por la influencia del personal de sala. El objetivo del presente trabajo es identificar y caracterizar los instrumentos relevantes de promoción de los vinos que utilizan los restaurantes, en función de la presencia de personal formado en vinos. Como resultado de un estudio realizado para una muestra de restaurantes de alto nivel, observamos que el contenido y el diseño de la carta de vinos se encuentran en gran medi…
LA ESTRATEGIA DE OUTSOURCING INTERNACIONAL EN ESPAÑA: UNA APROXIMACIÓN A LOS SECTORES MANUFACTUREROS TRADICIONALES
2009
RESUMENEn los últimos años el uso por parte de las empresas de la estrategia de outsourcing en sus dos vertientes (nacional e internacional)1 está siendo una práctica habitual en los países desarrollados, especialmente en los sectores manufactureros tradicionales. Dado el desarrollo experimentado y las implicaciones técnico-productivas y sociales que se derivan de su implementación, en este trabajo analizamos cuál ha sido la tendencia de esa estrategia en estos sectores durante el periodo 1985-2004 y contrastamos qué relación existe entre ésta y dos de sus principales factores determinantes: el tamaño y la experiencia internacional. De los resultados más generales se desprende que el outsou…
Nature in malls: Effects of a natural environment on the cognitive image, emotional response, and behaviors of visitors
2019
This study aims to assess the role of a natural environment and its effects on the following components of attitudes: cognitive image, affective response, and behavioral intentions. Using a survey conducted among 292 mall visitors, this study also examines how the perception of the atmosphere in a mall can indirectly affect behavioral intentions. The findings confirm that the components of cognitive image, namely, appealingly design features, may positively influence affective responses at malls. Affective response also positively impacts the behavioral intention of a mall visitor. Affective response features were found to be more powerful than the cognitive image and natural atmosphere att…
Climate change, ethics and sustainability: An innovative approach
2018
Our goal in this article is the analysis of the state of affairs, regarding the phenomenon of climate change and its impact in different areas. We synthesize the various approaches available in the scientific debate on this subject, mainly the one that affirms the existence of global warming and the current approach, which denies it. Beyond the controversy, what seems to be evident is that there is a multifactorial causality in a phenomenon that affects anthropogenic factors a well. Since some environmentalisms exclude the human being in their consideration of the ecosystem, and if they do, they accommodate man in their approaches always as a variable that distorts and deteriorates the envi…
International trade and migrant networks: Is It really about qualifications?
2014
Personal characteristics of migrants could help to strengthen the impact of migrant networks on bilateral trade. While most of the attention has been focused on immigrants' educational attainment, this paper focuses on the relevance of the tasks carried out by migrants. Our empirical results confirm that the existence of a large number of foreign-born workers with managerial duties is critical to explain the reduction of transaction costs caused by migrant networks.
