Type of judge and decisions in dismissal cases: An analysis of Labour Courts in Spain
El objetivo de este artículo es profundizar en la relación existente entre las decisiones judiciales de lo social en España en los casos de despido y los costes asociados a la extinción de los contratos laborales. Primero justificamos que los cambios en la probabilidad de que un juez falle a favor de un trabajador afectan a los costes de despido del empleador. En segundo lugar, examinamos cómo difiere dicha probabilidad cuando el juez es titular o sustituto. Se observa una mayor dispersión en la resolución de los casos de los jueces sustitutos, y un significativo repunte en los años de crisis económica de los fallos judiciales a favor del trabajador al considerar los jueces titulares, siendo este más débil en los casos de los sustitutosThe aim of this paper is to examine in detail the relationship between the decisionsof the Spanish labour courts regarding dismissal, and the costs associated with the terminationof employment contracts. We explain the changes in the probability that a judge ruling infavour of a worker affects the effective firing costs that the employer faces. We also examine how this probability differs depending on whether the judge is in charge of the court or is asubstitute. There is a greater dispersion in the resolution of cases when there are substitute judges, with a significant rise, during the economic crisis, of court decisions in favour of theworkers with permanent judges, which is less so with substitute judge
Estromatolitos pelágicos fosfatados relacionados con discontinuidades estratigráficas en el Cretácico del Penibético (provincia de Málaga)
En relación con discontinuidades estratigráficas en el Cretácico del Penibético se encuentran estromatolitos pelágicos fosfatados, constituidos por apatito criptocristalino (3 al 45 %). Muestran dos tipos de morfologías: a.- Oncoides en el seno de sedimentos. b.- Recubrimientos de superficies de paleokarst con morfología nodular, LLM o laminar. Son estructuras organosedimentarias constituidas por asoci aciones simbióticas de bacterias y foraminíferos encostrantes que se formaron en un alto fondo marino, en medio reductor, a profundidades próximas al nivel de mínimo contenido en oxígeno y en una zona afectada por corrientes ascendente
Natural and cyclical unemployment: a stochastic frontier decomposition and economic policy implications
The main goal of the present work is to split effective unemployment into two components, one dealing with the natural rate of unemployment, and another with cyclical unemployment. With this purpose in mind, an estimation of stochastic cost frontiers is performed where natural unemployment is identified as a lower limit and cyclical unemployment as the deviation of effective unemployment with regard to that limit. To achieve this purpose, information is used from the 17 autonomous communities in Spain over the period spanning 1982 to 2013. Results evidence a greater importance of the natural component as the principal determinant of effective unemployment at a regional scale. The latter part of the work compares stochastic frontier estimations to those obtained when applying univariate filters, which are in widespread use in economic literature. The main conclusion to emerge is that the proposed decomposition modifies the weight distribution amongst the various types of unemployment, increasing the importance of cyclical unemployment. This finding has significant implications for economic policy, such as the existence of a greater margin for aggregate demand policies in order to reduce cyclical unemployment, particularly during growth periods
A composed error model decomposition and spatial analysis of local unemployment
The differences in the regional unemployment rates, as well as their formation mechanism and persistence, have given rise to a great number of papers in the last decades. This work contributes to that strand of literature from two different perspectives. In the first part of our work, we follow the methodological proposal established by Hofler and Murphy (1989) and Aysun et al. (2014). We make use of an estimation of a stochastic cost frontier to breakdown the Spanish provincial effective unemployment (NUTS-3) in two different components: first one associated with aggregate supply side factors, and the other one more related to the aggregate demand side factors. The second part of our research analyzes the existence of spatial dependence patterns among the Spanish provinces in the effective unemployment and in both above mentioned components. The decomposition performed in the first part of our research will let us know the margin that the policymakers have when they deal with unemployment reductions by means of aggregate supply and aggregate demand policies. Finally, the spatial analysis of the unemployment rates amongst the Spanish provinces can potentially have also significant implications from an economic policy viewpoint since we find that there are common formation patterns or clusters of unemployment
Labor supply and the business cycle: The “Bandwagon Worker Effect”
The relationship between the labor force participation and the business cycle has become a topic in the economic literature. However, few studies have considered whether the cyclical sensitivity of the labor force participation is influenced by “social effects”. In this paper, we construct a theoretical model to develop the “Added Worker Effect” and the “Discouraged Worker Effect”, and we integrate the “social effects”, coining a new concept, the Bandwagon Worker Effect (BWE). To estimate the cyclical sensitivity of the labor force participation, we employ a panel dataset of fifty Spanish provinces for the period 1977–2015. Finally, we use spatial econometrics techniques to test the existence of the BWE in the local labor markets in Spain. Our results reveal that there exists a positive spatial dependence in the cyclical sensitivity of the labor force participation that decreases as we fix a laxer neighborhood criterion, which verifies the existence of the BWE. From the perspective of economic policy, our work confirms that “social effects” play a key role at the time of determining the economic dynamics of the territories

New Insights on Peniche Basin (West Iberian Margin) Crustal Structure Based on Gravity Data Interpretation
A gravimetric study has been carried out over a sector of the West Iberian Margin (WIM), constrained by well and seismic data. The analytic development was made through three main stages: the processing of different gravity datasets, the production of gravity anomaly maps and 2,5D models using the processed data, and the geophysical interpretation of maps and models. The final results of the interpretation achieved, allowed the determination of crustal structure and its variation/complexity along the WIM. The main obtained results concern the pre-saline infilling and the deep structure of the margin, which vary related to the location of first-order oblique fractures
First detection of the 448 GHz H2O transition in space
We present the first detection of the ortho-H2O 4_23-3_30 transition at 448
GHz in space. We observed this transition in the local (z = 0.010) luminous
infrared (IR) galaxy ESO 320-G030 (IRAS F11506-3851) using the Atacama Large
Millimeter/submillimeter Array (ALMA). The water 4_23-3_30 emission, which
originates in the highly obscured nucleus of this galaxy, is spatially resolved
over a region of ~65 pc in diameter and shows a regular rotation pattern
compatible with the global molecular and ionized gas kinematics. The line
profile is symmetric and well fitted by a Gaussian with an integrated flux of
37.0 +- 0.7 Jy km s-1 . Models predict this water transition as a potential
collisionally excited maser transition. On the contrary, in this galaxy, we
find that the 4_23-3_30 emission is primarily excited by the intense far-IR
radiation field present in its nucleus. According to our modeling, this
transition is a probe of deeply buried galaxy nuclei thanks to the high dust
optical depths (tau_100{\mu}m > 1, N_H > 1e24 cm-2) required to efficiently
excite it.Comment: Accepted for publication in A&A Letters; 4 pages, 5 figure
