22 p, 305.8 KB Exploring the sources of earnings transmission in spain / Cervini-Plá, María (Universitat Autònoma de Barcelona. Departament d'Economia Aplicada)
Este trabajo explora los mecanismos que hay detrás de la movilidad intergeneracional de ingresos en España mediante tres ejercicios: el cálculo de matrices de transición, la descomposición de las elasticidades y la estimación de regresiones por cuantiles. [...]
This paper explores the mechanisms behind the intergenerational earnings mobility in Spain by means of three exercises: calculating the transition matrix, decomposing the sources of earnings elasticity and estimating quantile regressions. [...]

20 p, 583.3 KB Exponentiated power Maxwell distribution with quantile regression and applications / Gallardo, Diego (Universidad de Atacama, Copiapó (Xile). Departamento de Matemática) ; Gómez, Yolanda (Universidad de Atacama, Copiapó (Xile). Departamento de Matemática) ; Segovia, Francisco A. (Universidad de Atacama, Copiapó (Xile). Departamento de Matemática)
In this paper we introduce an extension of the power Maxwell distribution. We also discuss a reparametrized version of this model applied to quantile regression. Some properties of the model and estimation based on the maximum likelihood estimation method are studied. [...]

18 p, 719.2 KB Median bilinear models in presence of extreme values / Santolino, Miguel (Universitat de Barcelona. Departament d'Econometria)
Bilinear regression models involving a nonlinear interaction term are applied in many fields (e. g. , Goodman's RC model, Lee-Carter mortality model or CAPM financial model). In many of these contexts data often exhibit extreme values. [...]

20 p, 452.1 KB Discrete generalized half-normal distribution and its applications in quantile regression / Gallardo, Diego (Universidad de Atacama, Copiapó (Xile). Departamento de Matemática) ; Gómez-Déniz, Emilio (Universidad de Las Palmas de Gran Canaria. Departamento de Métodos Cuantitativos en Economía y Gestión) ; Gómez, Héctor W. (Universidad de Antofagasta (Xile). Departamento de Matemáticas)
A new discrete two-parameter distribution is introduced by discretizing a generalized half-normal distribution. The model is useful for fitting overdispersed as well as underdispersed data. The failure function can be decreasing, bathtub shaped or increasing. [...]

14 p, 1.6 MB Flexible quantile regression models : application to the study of the purple sea urchin / Martínez-Silva, Isabel (Universidade de Santiago de Compostela. Departamento de Estatística) ; Roca-Pardiñas, Javier (Universidade de Vigo. Departamento de Estatística e Investigación Operativa) ; Lustres-Pérez, Vicente (Universidade de Santiago de Compostela. Departamento de Zooloxía e Antropoloxía Física) ; Lorenzo-Arribas, Altea (Universidade de Santiago de Compostela. Departamento de Estatística) ; Cadarso-Suárez, Carmen (Universidade de Santiago de Compostela. Departamento de Estatística)
In many applications, it is often of interest to assess the possible relationships between covariates and quantiles of a response variable through a regression model. In some instances, the effects of continuous covariates on the outcome are highly nonlinear. [...]

48 p, 492.8 KB Innovation, public support and productivity in Colombia / Busom i Piquer, Isabel ; Vélez-Ospina, Jorge Andrés
We investigate the association between perceived barriers to innovation and the allocation of public support for innovation in manufacturing and service industries in Colombia, as well as the potential heterogeneity of returns to innovation across the firm-level productivity distribution. [...]

17 p, 529.7 KB Innovation sources and productivity : a quantile regression analysis / Segarra Blasco, Agustí, 1958- (Universitat Rovira i Virgili. Departament d'Economia) ; Xarxa de Referència en Economia Aplicada (XREAP)
This paper explores the effects of two main sources of innovation -intramural and external R&D- on the productivity level in a sample of 3,267 Catalan firms. The data set used is based on the official innovation survey of Catalonia which was a part of the Spanish sample of CIS4, covering the years 2002-2004. [...]
