El análisis por envoltura de datos (DEA) convencional considera el proceso productivo como una caja negra, esto es, como un proceso único que realiza la transformación de las entradas en salidas. Existen, sin embargo, enfoques DEA que abren esa caja y distinguen dentro de la misma diferentes subprocesos, cada uno con sus propias entradas y…
Abstract: In participatory budgeting, citizens are invited to vote on different projects. Those with the most votes are chosen and implemented. The voting rules used in practice are usually based on single winner elections. A shortcoming of using these rules is that they do not take into account the costs of the projects, although those…
Algunas de las escalas cualitativas utilizadas por diferentes instituciones y organismos no son uniformes: los agentes pueden percibir que la proximidad psicológica entre cada par de términos consecutivos de la escala no sea idéntica. En esta charla se abordan las escalas cualitativas no uniformes a través de la noción de medida de proximidad ordinal y…
We estimate Okun’s relationship for four European countries (France, Germany, the Netherlands and Spain) with a nonparametric procedure, without imposing a previous specific functional form. We apply the non parametric MARS methodology that endogenously detects multiple thresholds and therefore is able to identify multiple possible regimes. In addition, we control for the Euro area crisis…
Presentamos un método para estimar de manera indirecta las cantidades transportadas de ciertos productos entre dos regiones en aquellos casos en los que solamente están disponibles los datos de la suma de sus flujos. Este método se basa en la aplicación de un modelo gravitacional clásico introducido en un problema de optimización. El objetivo de…
The relocation of production and exports from the North to the South has been a central feature of economic globalization. Using data on approximately 5,000 products, this paper describes this process over the 1996-2014 period and assesses its impact on cross-country growth. Although increased competition from lower income countries tended to have a significant negative…
Abstract: This paper investigates the dynamics, propagation and drivers of macroeconomic volatility from a global perspective. A hierarchical volatility factor model is designed to estimate and decompose the time-varying volatility of output growth across countries into global, regional, and idiosyncratic components. We find that the global volatility component has been systematically declining over time, which is…
Abstract: Examining the determinants of qualification and skills mismatches has become a recurrent theme in the literature. Educational mismatches have serious consequences for individuals and can seriously hamper wages, job satisfaction and labour market prospects. These effects can be drammatical among immigrants, since they add up to an already disadvantaged position in the labour market….
Abstract: Convenient scheduling, characterized by adequate flight frequency, is the main quality attribute for airline services. However, the effect of airline alliances on this important dimension of service quality has received almost no attention in the literature. This paper fills this gap by providing such an analysis in a model where flight frequency affects schedule…
Abstract: Este trabajo analiza la evolución y los determinantes de la desigualdad salarial mensual y horaria en España desde 1995 a 2014 utilizando los datos de la Encuesta Cuatrienal de Estructura Salarial. El aumento de la jornada a tiempo parcial es la variable clave que explica el distinto comportamiento observado en ambas. La primera aumenta…
