Computing Markov-Perfect Optimal Policies in Business-Cycle Models

Time-inconsistency is an essential feature of many policy problems (Kydland and Prescott, 1977). This paper presents and compares three methods for computing Markov-perfect optimal policies in stochastic nonlinear business cycle models. The methods considered include value function iteration, generalized Euler-equations, and parameterized shadow prices. In the context of a business cycle model in which a scal authority chooses government spending and income taxation optimally, while lacking the ability to commit, we show that the solutions obtained using value function iteration and generalized Euler equations are somewhat more accurate than that obtained using parameterized shadow prices. Among these three methods, we show that value function iteration can be applied easily, even to environments that include a risk-sensitive scal authority and/or inequality constraints on government spending. We show that the risk-sensitive scal authority lowers government spending and income-taxation, reducing the disincentive households face to accumulate wealth.

Health at a glance: Europe 2012.

This second edition of Health at a Glance: Europe presents a set of key indicators of health and health systems in 35 European countries, including the 27 European Union member states, 5 candidate countries and 3 EFTA countries. The selection of indicators is based largely on the European Community Health Indicators (ECHI) shortlist, a list of indicators that has been developed by the European Commission to guide the development and reporting of health statistics. It is complemented by additional indicators on health expenditure and quality of care, building on the OECD expertise in these areas. Contents: Introduction 12 Chapter 1. Health status 15 1.1.

Additional information on demographic and economic context 143 Most European countries have reduced tobacco consumption via public awareness campaigns, advertising bans and increased taxation. The percentage of adults who smoke daily is below 15% in Sweden and Iceland, from over 30% in 1980. At the other end of the scale, over 30% of adults in Greece smoke daily. Smoking rates continue to be high in Bulgaria, Ireland and Latvia (Figure 2.5.1). Alcohol consumption has also fallen in many European countries. Curbs on advertising, sales restrictions and taxation have all proven to be effective measures. Traditional wine-producing countries, such as France, Italy and Spain, have seen consumption per capita fall substantially since 1980. Alcohol consumption per adult rose significantly in a number of countries, including Cyprus, Finland and Ireland (Figure 2.6.1).This resource was contributed by The National Documentation Centre on Drug Use.

Experiències catalanes, angleses i irlandeses en el millorament de l’accès a l’habitatge

El Grup de Recerca d´Accés a l´Habitatge de la Universitat Rovira i Virgili ha portat a terme durant l´any 2011 una sèrie d´activitats gràcies a l´ajuda concedida per la convocatòria de l´AGAUR PBR-DGR 2010, que ha donat suport al Grup tant de forma directa (per exemple, en viatges i dietes) com indirecta (gràcies a l´ajuda prestada per la Sra. Helaine Cristina Madeira Santos, becària de suport al Grup de Recerca, que ha portat a terme tasques de coordinació i investigació). Així, el Grup ha portat a terme tasques d´investigació (per exemple, la signatura d´un Conveni amb l’Agència de l’Habitatge de Catalunya amb la finalitat de portar a terme en el termini de 3 anys l’elaboració d´un marc legislatiu sobre les tinences intermitges en el Dret català); tasques de formació (gràcies a la participació en Congressos i Jornades); esta coordinant una xarxa sobre grups d´habitatge (per exemple, mitjançant un Congrés internacional sobre habitatge celebrat a Granada); ha publicat llibres i articles científics (per exemple, la publicació dels treballs presentats en les III Jornades Internacionals de Housing de 2010); i finalment cal destacar que l´activitat del Grup ha tingut un gran impacte en els mitjans de comunicació. Tot aquest treball ha permès al Grup arribar a unes conclusions sobre el status quo de l´habitatge a Espanya, per exemple les mancances del mercat d´habitatge en propietat i en lloguer i els aspectes que cal reformar quant al règim tributari i processal d´aquestes formes de tinença immobiliària. La principal conclusió, però, és la necessitat de regular noves formes d´entendre la tinença de la terra tot seguint els models ja presents en altres països europeus (principalment, Anglaterra i Irlanda), com la propietat compartida i la propietat temporal, figures en les quals està aprofundint actualment el Grup de recerca.

Una reflexión sobre la impronta romana del 'beneficio de separación de patrimonios' en el Código Civil catalán

The roman institution of the separatio bonorum is a pretorian remedy that relies on the principle of equity, created as to protect the deceased creditors and/or legatees. It provides them a"benefit" in the case of selling the goods of the heir-deubtor, enabling them to separate and reserve for themselves that whole patrimonium, as to avoid that by the act of selling, the heirs creditors could go to it; and like this they maintain intact their guarantee, which relies on the whole goods and assets left by the deceased. The separation of patrimonies implied the existence of 2 different groups of goods: that of the heirs" and that one of the deceased, which are not the same in legal terms, in spite of having a common owner at this point, the heir. This institution was regulated in the 6th title of the 42nd book of the Digesto, and in the 72th title, 7th book of the Justinean Code, and its interest is really high due to its material complexity and its procedure. The aim of this work is to analyze the institution of the separatio bonorum in Roman Law, and its importance in the same figure, actually regulated in the 4th book of the Catalan civil code.

La Novela 53, 6 y sus precedentes inmediatos

Por ser la cuarta vidual, como corroboran las Nov. 53, 6; 74, 5 y 117, 5, una figura vinculada tanto al Derecho de familia, en concreto, a la denominada, en doctrina, cuarta marital o uxoria en su acepción penal, pues en ésta encuentra una parte importante de sus raíces, como al Derecho sucesorio; su historia y fines se entenderán mejor si se integra en la evolución de ambos sistemas. Lo dicho justifica, a mi juicio, el interés de un estudio que, como éste, se centre, por una parte, en la institución que fue el precedente histórico inmediato de la cuarta vidual y, por otra, en el análisis de la Novela que, por primera vez, reguló el derecho a la cuarta en favor del cónyuge viudo, esto es, la 53, 6.

Genotyping microarray for CSNB-associated genes.

PURPOSE: Congenital stationary night blindness (CSNB) is a clinically and genetically heterogeneous retinal disease. Although electroretinographic (ERG) measurements can discriminate clinical subgroups, the identification of the underlying genetic defects has been complicated for CSNB because of genetic heterogeneity, the uncertainty about the mode of inheritance, and time-consuming and costly mutation scanning and direct sequencing approaches. METHODS: To overcome these challenges and to generate a time- and cost-efficient mutation screening tool, the authors developed a CSNB genotyping microarray with arrayed primer extension (APEX) technology. To cover as many mutations as possible, a comprehensive literature search was performed, and DNA samples from a cohort of patients with CSNB were first sequenced directly in known CSNB genes. Subsequently, oligonucleotides were designed representing 126 sequence variations in RHO, CABP4, CACNA1F, CACNA2D4, GNAT1, GRM6, NYX, PDE6B, and SAG and spotted on the chip. RESULTS: Direct sequencing of genes known to be associated with CSNB in the study cohort revealed 21 mutations (12 novel and 9 previously reported). The resultant microarray containing oligonucleotides, which allow to detect 126 known and novel mutations, was 100% effective in determining the expected sequence changes in all known samples assessed. In addition, investigation of 34 patients with CSNB who were previously not genotyped revealed sequence variants in 18%, of which 15% are thought to be disease-causing mutations. CONCLUSIONS: This relatively inexpensive first-pass genetic testing device for patients with a diagnosis of CSNB will improve molecular diagnostics and genetic counseling of patients and their families and gives the opportunity to analyze whether, for example, more progressive disorders such as cone or cone-rod dystrophies underlie the same gene defects.

Epidemiology of cleft palate in Europe: implications for genetic research.

OBJECTIVE: To describe the epidemiology of cleft palate (CP) in Europe. DESIGN AND SETTING: A descriptive epidemiological study on 3852 cases of CP, identified (1980 through 1996) from more than 6 million births from the EUROCAT network of 30 registers in 16 European countries. RESULTS: Significant differences in prevalence in Europe between registries and within countries were observed. A total of 2112 (54.8%) CP cases occurred as isolated, 694 (18.0%) were associated with other defects such as multiple congenital anomalies, and 1046 (27.2%) were in recognized conditions. The study confirmed the tendency toward female prevalence (sex ratio [SR] = 0.83), particularly among isolated cases (SR = 0.78) even if SR inversion is reported in some registries. A specific association with neural tube defects (NTDs) in some registers is reported. CONCLUSION: The differences identified in Europe (prevalence, sex, associated anomalies) can be only partially explained by methodological reasons because a common methodology was shared among all registries for case ascertainment and collection, and CP is an easy detectable condition with few induced abortions. The complex model of inheritance and the frequently conflicting results in different populations on the role of genes that constitute risk factors suggest the presence of real biological differences. The association of CP/NTD in an area with a high prevalence of NTDs can identify a group of conditions that can be considered etiologically homogeneous. The epidemiological evaluation can guide genetic research to specify the role of etiological factors in each different population

Mutations in DNAH5 account for only 15% of a non-preselected cohort of patients with primary ciliary dyskinesia.

BACKGROUND: Primary ciliary dyskinesia (PCD) is characterised by recurrent infections of the upper respiratory airways (nose, bronchi, and frontal sinuses) and randomisation of left-right body asymmetry. To date, PCD is mainly described with autosomal recessive inheritance and mutations have been found in five genes: the dynein arm protein subunits DNAI1, DNAH5 and DNAH11, the kinase TXNDC3, and the X-linked retinitis pigmentosa GTPase regulator RPGR. METHODS: We screened 89 unrelated individuals with PCD for mutations in the coding and splice site regions of the gene DNAH5 by denaturing high performance liquid chromatography (DHPLC) and sequencing. Patients were mainly of European origin and were recruited without any phenotypic preselection. RESULTS: We identified 18 novel (nonsense, splicing, small deletion and missense) and six previously described mutations. Interestingly, these DNAH5 mutations were mainly associated with outer + inner dyneins arm ultrastructural defects (50%). CONCLUSION: Overall, mutations on both alleles of DNAH5 were identified in 15% of our clinically heterogeneous cohort of patients. Although genetic alterations remain to be identified in most patients, DNAH5 is to date the main PCD gene.

Bienestar social e impuesto sobre la renta

El presente artículo pretende ampliar el modelo original de SANDMO (Journal of Public Economics, 1981 , Vol. 16), relativo a evasión e imposición óptima, en dos direcciones. De un lado, haciendo extensivo el marco de preferencias redistributivas hacia otros objetivos sociales distintos del utilitarista; asimismo, permitiendo el que los sujetos no defraudadores puedan diferir entre sí, de acuerdo con la bibliografía más corriente sobre el tema, por razón de la capacidad productiva que posean en el mercado de trabajo. Dichas modificaciones, además de deslindar los aspectos de aversión al riesgo de lo que propiamente es el grado de concavidad de la función de bienestar, facilitan una más completa descripción del modo como operan los factores que inciden en la conducta del contribuyente.

Mutations in LONP1, a mitochondrial matrix protease, cause CODAS syndrome.

Cerebral, ocular, dental, auricular, skeletal anomalies (CODAS) syndrome (MIM 600373) was first described and named by Shehib et al, in 1991 in a single patient. The anomalies referred to in the acronym are as follows: cerebral-developmental delay, ocular-cataracts, dental-aberrant cusp morphology and delayed eruption, auricular-malformations of the external ear, and skeletal-spondyloepiphyseal dysplasia. This distinctive constellation of anatomical findings should allow easy recognition but despite this only four apparently sporadic patients have been reported in the last 20 years indicating that the full phenotype is indeed very rare with perhaps milder or a typical presentations that are allelic but without sufficient phenotypic resemblance to permit clinical diagnosis. We performed exome sequencing in three patients (an isolated case and a brother and sister sib pair) with classical features of CODAS. Sanger sequencing was used to confirm results as well as for mutation discovery in a further four unrelated patients ascertained via their skeletal features. Compound heterozygous or homozygous mutations in LONP1 were found in all (8 separate mutations; 6 missense, 1 nonsense, 1 small in-frame deletion) thus establishing the genetic basis of CODAS and the pattern of inheritance (autosomal recessive). LONP1 encodes an enzyme of bacterial ancestry that participates in protein turnover within the mitochondrial matrix. The mutations cluster at the ATP-binding and proteolytic domains of the enzyme. Biallelic inheritance and clustering of mutations confirm dysfunction of LONP1 activity as the molecular basis of CODAS but the pathogenesis remains to be explored.

Analysis of the mitochondrial DNA of Schizophrenia patients by next generation sequencing

Mitochondrial DNA (mtDNA), a maternally inherited 16.6-Kb molecule crucial for energy production, is implicated in numerous human traits and disorders. It has been hypothesized that the presence of mutations in the mtDNA may contribute to the complex genetic basis of schizophreniadisease, due to the evidence of maternal inheritance and the presence of schizophrenia symptoms in patients affected of a mitochondrial disorder related to a mtDNA mutation. The present project aims to study the association of variants of mitochondrial DNA (mtDNA), and an increased risk of schizophrenia in a cohort of patients and controls from the same population. The entire mtDNA of 55 schizophrenia patients with an apparent maternal transmission of the disease and 38 controls was sequenced by Next Generation Sequencing (Ion Torrent PGM, Life Technologies) and compared to the reference sequence. The current method for establishing mtDNA haplotypes is Sanger sequencing, which is laborious, timeconsuming, and expensive. With the emergence of Next Generation Sequencing technologies, this sequencing process can be much more quickly and cost-efficiently. We have identified 14 variants that have not been previously reported. Two of them were missense variants: MTATP6 p.V113M and MTND5 p.F334L ,and also three variants encoding rRNA and one variant encoding tRNA. Not significant differences have been found in the number of variants between the two groups. We found that the sequence alignment algorithm employed to align NGS reads played a significant role in the analysis of the data and the resulting mtDNA haplotypes. Further development of the bioinformatics analysis and annotation step would be desirable to facilitate the application of NGS in mtDNA analysis.

Al ser el Impuesto sobre Sucesiones un tributo generacional su importe -que no su devengo- es fácilmente previsible y susceptible de una favorable planificación. Ciertamente, la divina providencia puede frustrar de forma sorprendente -si es que alguien puede sorprenderse de que la vida esté sujeta a caducidad- la más alambicada de las planificaciones fiscales de la sucesión. Pero es igualmente irrefutable que se tiene toda la vida por delante para programar un relevo generacional en la titularidad del patrimonio lo más liviano posible, en términos tributarios.
