Minimum consumption and transitional dynamics in wealth distribution

This paper investigates the evolution of wealth distribution in a one sector growth model along its transition path. A key feature of the model is that a household's consumption cannot fall below a positive level each period. This requirement introduces a positive association between the intertemporal elasticity of substitution and household wealth. Households only differ in their initial holdings of capital. The model is calibrated to match some key statistics of the US economy. The level of inequality in the wealth distribution of our artificial economy has a n inverted Ushape. The level of wealth inequality and its evolution resembles that of the US economy. However, our model illustrates that the existence of a Kuznets curve is very sensitive tothe sources of growth: whether it is driven by productivity growth or capital accumulation. Additionally, our model predicts an upsurge in wealth inequality following the productivity slowdown in the 1970's

A photometric comprehensive study of circumnuclear star forming rings: the sample

We present photometry in U, B, V, R and I continuum bands and in H$\alpha$ and H$\beta$ emission lines for a sample of 336 circumnuclear star forming regions (CNSFR) located in early type spiral galaxies with different levels of activity in their nuclei. They are nearby galaxies, with distances less than 100 Mpc, 60\% of which are considered as interacting objects. This survey of 20 nuclear rings aims to provide insight into their star formation properties as age, stellar population and star formation rate. Extinction corrected H$\alpha$ luminosities range from $1.3\times 10^{38}$ to $4\times 10^{41} erg s^{-1}$, with most of the regions showing values between 39.5 $\leq log L(H\alpha) \leq$ 40, which implies masses for the ionizing clusters higher than $2\times 10^{5} M_\odot$. H$\alpha$ and H$\beta$ images have allowed us to obtain an accurate measure of extinction. We have found an average value of A$_V$ = 1.85 magnitudes. (U-B) colour follows a two maximum distribution around (U-B)$\simeq$ -0.7, and -0.3; (R-I) also presents a bimodal behaviour, with maximum values of 0.6 and 0.9. Reddest (U-B) and (R-I) regions appear in non-interacting galaxies. Reddest (R-I) regions lie in strongly barred galaxies. For a significant number of HII regions the observed colours and equivalent widths are not well reproduced by single burst evolutionary theoretical models.Comment: Accepted for publication in MNRAS.

Microcréditos: España y Bolivia

En el presente trabajo se va a hacer una comparación de la evolución de los microcréditos en dos países totalmente diferentes por la situación en la que se encuentran, ya que el primero es un país desarrollado como es el caso de España y el segundo en vías de desarrollo que es Bolivia. Se va a mostrar cómo han evolucionado los microcréditos en sus inicios y quienes fueron los responsables de fomentarlos tanto en España como en Bolivia. El sistema financiero tradicional no concedía financiación a las personas con bajos recursos porque no podían ofrecer garantías o avales, además de tener un alto riesgo de impago, por lo que se crearon estos instrumentos financieros para poder ayudar a las personas que necesitaban conseguir financiación, porque antes de la difusión de estos servicios estas personas estaban marginadas por el sistema financiero. Todo esto fue posible por medio de instituciones, organizaciones y entidades mediante programas sociales que incluían los microcréditosIn the present work, a comparison of the evolution of microcredits will be made of two totally different countries because of the situation in which they find themselves, since the first one is a developed country, as is the case of Spain and the second is developing, which is Bolivia. It will show how microcredits have evolved in their beginnings and who were responsible for promoting them both in Spain and Bolivia. The traditional financial system did not grant financing to people with low resources because they could not offer guarantees or guarantees, besides having a high risk of default, so these financial instruments were created in order to help people who needed to get financing, because before the diffusion of these services these people were marginalized by the financial system. All this was possible through institutions, organizations and entities through social programs that included microcreditsDepartamento de Economía Financiera y ContabilidadGrado en Administración y Dirección de Empresa

Asturias' agriculture crisis in the 18th century. An approximation to its study

El cereal fue el alimento básico que permitió subsistir a la sociedad del Antiguo Régimen, por lo que su abasto fue una de las principales tareas, tanto del gobierno central, como una preocupación constante de los gobiernos locales, y en última instancia de las oligarquías municipales. En este breve estudio, nos centramos en las principales crisis agrarias acaecidas en la Asturias del siglo XVII y, más concretamente, en las que afectaron más de cerca a la capital del Principado, Oviedo. Tras un siglo XVI plagado de problemas de abastecimiento, dada la poca productividad de los cereales tradicionales en la región, el siglo XVII parece dar un respiro al cabildo municipal. A pesar de ello, la geografía específica asturiana, y las cíclicas climatologías desfavorables -periodos de gran humedad seguidos de sequías- perjudicó en no pocas ocasiones al territorio ástur.The supply of bread was very important for the survival of people of the Ancien Regime. It involved, for municipal politicians of that age, a great effort to prevent that the agrarian crisises could lead to demographical crisises, which could reduce the number of people in the city, and it would cause social disturbances. In this article, we make an outline of the most important agrarian crisises (that there were in Asturias) in the 17th century, although we centre on the city of Oviedo. These crisises were mainly bad weather, which ocasionaly was very rainy or very dry, so that municipal politicians had to buy cereals outside Asturias to provide bread to the city. In spite of, some years were good and there was not shortage of cereals in the Asturias at that time which could sell outside

Tributación por utilización de dominio publico local de las empresas suministradoras de servicios en red

El objeto de este trabajo es el análisis de la reforma del marco tributario local aplicable a las empresas suministradoras de servicios en red por el pago de la tasa por ocupación de dominio público local, tras los cambios tecnológicos y regulatorios que han posibilitado la transición de un mercado de monopolio a la competencia
