Mortgage defaults
We incorporate house price risk and mortgages into a standard incomplete market (SIM) model. We calibrate the model to match U.S. data and we show that the model also ac- counts for non-targeted features of the data such as the distribution of down payments, the life-cycle profile of home ownership, and the mortgage default rate. In addition, we show that the average coefficients that measure the agents' ability to self-insure against income shocks are similar to those of a SIM model without housing (as presented by Kaplan and Violante, 2010). However, incorporating housing increases the values of these coefficient for younger agents, which narrows the gap between the SIM model's implications and the data. The response of consumption to house price shocks is minimal. We also study the effects of default prevention policies. Introducing a minimum down payment requirement of 15% reduces defaults on mortgages by 30%, reduces the home ownership rate up to only 0.2 percentage points (if the aggregate house price level does not adjust), and may cause house prices to decline up to 0.7% (if home ownership does not adjust). Garnishing defaulters' income in excess of 43% of median consumption for one year produces a similar decline in defaults; but, since it reduces the median equilibrium down payment from 19% to 9%, it boosts home ownership up to 4.3 percentage points (if the aggregate house price level does not adjust) and may increase house prices up to 16.1% (if home ownership does not adjust). The introduction of minimum down payments or income garnishment benefit a majority of the population.Mortgage loans ; Default (Finance)
Sampling Theorem and Discrete Fourier Transform on the Hyperboloid
Using Coherent-State (CS) techniques, we prove a sampling theorem for
holomorphic functions on the hyperboloid (or its stereographic projection onto
the open unit disk ), seen as a homogeneous space of the
pseudo-unitary group SU(1,1). We provide a reconstruction formula for
bandlimited functions, through a sinc-type kernel, and a discrete Fourier
transform from samples properly chosen. We also study the case of
undersampling of band-unlimited functions and the conditions under which a
partial reconstruction from samples is still possible and the accuracy of
the approximation, which tends to be exact in the limit .Comment: 22 pages, 2 figures. Final version published in J. Fourier Anal. App

Towards the implementation of a preference-and uncertain-aware solver using answer set programming
Logic programs with possibilistic ordered disjunction (or LPPODs) are a recently defined logic-programming framework based on logic programs with ordered disjunction and possibilistic logic. The framework inherits the properties of such formalisms and merging them, it supports a reasoning which is nonmonotonic, preference-and uncertain-aware. The LPPODs syntax allows to specify 1) preferences in a qualitative way, and 2) necessity values about the certainty of program clauses. As a result at semantic level, preferences and necessity values can be used to specify an order among program solutions. This class of program therefore fits well in the representation of decision problems where a best option has to be chosen taking into account both preferences and necessity measures about information. In this paper we study the computation and the complexity of the LPPODs semantics and we describe the algorithm for its implementation following on Answer Set Programming approach. We describe some decision scenarios where the solver can be used to choose the best solutions by checking whether an outcome is possibilistically preferred over another considering preferences and uncertainty at the same time.Postprint (published version

Plan de negocios para montaje de una planta de producción de arneses de uso automotriz Arneses Automotrices del Ecuador
The business plan proposes the creation of a production of automotive harnesses to provide companies that assemble vehicles locally. The developed plan consider the reality of the automotive environment in Ecuador, where government regulations require a change in the productive matrix, promoting the development and production of goods and services in the country. Additionally regulations limiting the import of vehicles and parts for local assembly, it is required by COMEX. (Comité de Comercio Exterior)
The business is consider a volume of 42500 units assembled annually, regulated by COMEX. The volume in cash market value exceeds 1.86 million US dollars, with a discount rate of 19.34%, the balance point in the first year is 15,265 units produced, and requires an initial investment of 24.000.000 de dólares en un año, considerando el abastecimiento para el ensamblaje de automóviles, camionetas (Pick Up) y SUV´s.
El proyecto tiene una Valor Presente Neto de 1.535.000 dólares.
Como se puede ver el proyecto bajo las condiciones y premisas presentadas en rentable, siendo una oportunidad de inversión
Contextualització, definició i caracterÃstiques de la gimnà stica aquà tica
L’anà lisi de l’evolució de les prà ctiques fÃsiques de lleure en la nostra societat, ens revela que les activitats aquà tiques de condicionament fÃsic saludable, mitjançant la música i la recreació, es consoliden de manera important. Aquestes propostes, a causa de nous plantejaments conceptuals i de formes d’actuació de l’actual societat, s’entenen de manera eclèctica, tot superant les limitacions que aportaven d’altres models tradicionals. En conseqüència, ha sorgit una à mplia varietat d’opcions d’exercitació que necessiten ser situades, definides i delimitades amb precisió per garantir que l’avenç quantitatiu esmentat també ho sigui a nivell qualitatiu, de tal manera que es pugui tutelar adequadament aquest procès emergent
Bolivia landlocked; a long search for solutions
La falta de salida al mar de Bolivia, supone un inmenso desafÃo y una desventaja notable para esta nación en diferentes sentidos. A más de un siglo de perder su soberanÃa al mar, en la Guerra del PacÃfico, se siguen presentando polémicas entre las naciones latinoamericanas en torno a este tema, que ponen en riesgo la estabilidad y el equilibrio regional que se ha mantenido durante años. El actual momento de esta situación está marcado por la demanda de Bolivia ante la Corte Internacional de Justicia (CIJ) de la Haya, lo cual ha tensionado sus relaciones con Chile y nos lleva a plantear la hipótesis que en un corto plazo Bolivia no obtendrá salida al mar producto de un tratado bilateral que le conceda esta posibilidad, por razones que se explicarán más adelante.Lack of landlocked Bolivia is a huge challenge and a significant disadvantage to this nation in different ways. More than a century to lose this power in the Pacific War, there continue to be controversial among Latin American nations on this issue, which endanger the stability and regional balance that has been maintained for years at risk. The current time of this situation is marked by the demand for Bolivia before the International Court of Justice (ICJ) in The Haya, which has strained relations with Chile and leads us to hypothesize that in a short term Bolivia will not get out sea product of a bilateral treaty to provide this opportunity for reasons that will be explained later.Pregrad
Contextualización, definición y caracterÃsticas de la gimnasia acuática
El análisis de la evolución de las prácticas fÃsicas de ocio en nuestra sociedad, nos revela que las actividades acuáticas de acondicionamiento fÃsico saludable a través de la música y la recreación se consolidan de manera importante. Tales propuestas, debido a nuevos planteamientos conceptuales y modos de actuación de la actual sociedad, se entienden de manera ecléctica, superando las limitaciones que aportaban otros modelos tradicionales. En consecuencia, ha surgido una amplia variedad de opciones de ejercitación que necesitan ser ubicadas, definidas y delimitadas con precisión para garantizar que dicho avance cuantitativo también lo sea a nivel cualitativo, de tal forma que se pueda tutelar adecuadamente este emergente proceso
