Seminario 17/18: M.M. Sánchez de la Vega (U. Murcia) – Estimation of Gross Value Added, Spatial Dependence and Panel Data: Evidence in Municipalities of Region of Murcia Case

municipios3

The aim of this work is to propose a statistical methodology in order to estimate the macromagnitud Gross Value Added per capita (GVApc) in the local geographical area. The procedure proposed consists of estimating a panel model which includes Griffith’s spatial filtering (1996, 2000) to capture the spatial dependence in the whole analyzed period. The…

Seminario 17/15: Magdalena Kapelko (Wroclaw University of Economics) – Measuring Productivity Change Accounting for Adjustment Costs: Evidence from the Food Industry in the European Union

productivity

Abstract This paper extends the measurement of dynamic productivity change over time to provide its full decomposition into economically meaningful components in the Data Envelopment Analysis framework. The dynamic approach accounts for dynamics of production decisions via adjustment costs and is visualized as a dynamic Luenberger productivity change indicator. The paper also estimates the dynamic…

Seminario 17/15: Small-scale fisheries in Brazil: a not-so-invisible problem

Brazil is proportionally a relatively unimportant player in the world fisheries scenario. However, small-scale fisheries (SSF) specifically are crucial for local livelihoods and the food security of millions of people, both on the coast and inland. Such fisheries provide more than 50% of the total Brazilian catches, suggesting that they can be highly impacting on…

Seminario 17/01: – Jose G. Clavel (U. Murcia)- Total Information Analysis: Representation of Categorical Data Through Clusters

clusters

Abstract: Due to the presence of duality, cluster analysis has been proposed to analyze Total Information Analysis super distance matrix instead of a row-column joint graph. But the same duality causes that the traditional methods of clustering are not always capable to produce meaningful results. In this paper following Nishisato (2014), the clustering with p-percentile…

Seminario 16/08: – Mohammed Dore (U. Brock)- Spain in the Euro Area: Causal consequences leading to multiple desequilibria.

map-europe-spain

We consider quarterly data of the Spanish economy from 1987 to 2013 to establish causal interconnections in a model free manner, using symbolic dynamics and permutation entropy (PE) and establish the exogeneity of adoption of the Euro (in Jan 1999) as the governing mechanism that leads to the key causal impacts on (1) interest rates,…

27 Noviembre: Seminario 2015/27 – M.M. Sánchez de la Vega (U. Murcia) – El rechazo al fraude fiscal en España: Antes y después de la Gran crisis

fraude fiscal

Abstract This paper analyzes the rejection of tax fraud in Spain before and after the Great Depression and studies the role of certain determinants of two categories: internal or individual, and contextual, social or institutional. We use a logit model obtaining that the rejection of tax evasion depends positively on individual variables such as age…

13 Noviembre: Seminario 2015/25 – M.V. Caballero (U. Murcia) – Gráficos de Recurrencia Simbólicos

grafcaosliue0

Abstract Análogamente a como los gráficos de recurrencia permiten visualizar la correlación integral de una serie temporal, definimos la herramienta gráfica para la correlación integral simbólica de una serie vectorial, son los gráficos de recurrencia simbólicos y gráficos de recurrencia simbólicos coloreados.Estos gráficos informan sobre la estructura de la serie como se ilustrara con distintos…

30 Octubre: Seminario 2015/22 – M. I. González-Martínez (U. Murcia) – Nonconstant reputation effect in a dynamic tourism demand model for Spain

spain_tourism

Abstract Following the ideas of the Tourism Area Life Cycle (TALC) theory, we propose a dynamic econometric model for tourism demand where the reputation effect (the effect of the lagged demand on the current tourism demand) is not constant, but dependent on congestion. We test the model using panel data from Spanish regions during the…

Seminario 15/11: J. Sánchez-Campillo (U. Granada) – ¿En los centros privados se inflan las calificaciones de los estudiantes?

calificacionesfinales

Abstract Over ninety percent of the students taking the Spanish university admissions test (PAU) in recent years have passed on their first try. However, many public university degree programmes require high grades of their applicants. This requirement was reinforced in 2010 with the approval of the new PAU, which introduced a set of voluntary tests,…

Seminario 14/30: M.V. Caballero (UMU) – Symbolic Correlation Integral. Getting Rid of the Proximity Parameter

MVictoria

Abstract In this paper we introduce the symbolic correlation integral SC(m), which avoids the noisy parameter ” of the classical correlation integral defined by Grassberger-Procaccia. Moreover we provide the asymptotic distribution of SC(m) under the null of i.i.d. With a MonteCarlo simulation we show the size and the power performance of the new test under…
