An estimation of the wage curve for Uruguay

This paper analyzes the existence of a wage curve in Uruguay. We run several models using data for the period 1986-2005. We use two different proxies of the wage and we estimate both microdata and cell-mean regressions. Besides, we run the model for the whole sample and for groups of individuals disaggregated by level of education, gender, age and occupation. The results are consistent with the range of values found in similar studies for other countries. We find a negative relation between unemployment and wages. Specifically, we obtain an elasticity of -0.09. We find a higher elasticity for the youth, women and less educated workers. We also obtain difference results when disaggregating by occupation and formality. The results suggest that an increase of unemployment pushes up informality and self-employment which lead to a depression of earnings in these sectors. Thus, informality and self-employment would act as a buffer for unemployed formal wage earners.wage curve, unemployment

Ulam's method for Lasota-Yorke maps with holes

Ulam's method is a rigorous numerical scheme for approximating invariant densities of dynamical systems. The phase space is partitioned into connected sets and an inter-set transition matrix is computed from the dynamics; an approximate invariant density is read off as the leading left eigenvector of this matrix. When a hole in phase space is introduced, one instead searches for \emph{conditional} invariant densities and their associated escape rates. For Lasota-Yorke maps with holes we prove that a simple adaptation of the standard Ulam scheme provides convergent sequences of escape rates (from the leading eigenvalue), conditional invariant densities (from the corresponding left eigenvector), and quasi-conformal measures (from the corresponding right eigenvector). We also immediately obtain a convergent sequence for the invariant measure supported on the survivor set. Our approach allows us to consider relatively large holes. We illustrate the approach with several families of examples, including a class of Lorenz maps.Comment: 20 pages, 6 figures, added section on Lorenz-like map

Técnicas de reprodução humana assistida heterólogas: o direito de conhecer as origens. Legislação versus subjetividade?

Las técnicas de reproducción humana asistida, y en particular las heterólogas, plantean una serie de problemas que se ubican en el cruce tripartito de la ciencia, el derecho y la subjetividad. En este artículo investigamos la relación entre la legislación recientemente aprobada en Argentina respecto del anonimato relativo del donante y las respuestas de los usuarios de técnicas heterólogas —en este caso, la ovodonación—, en cuanto al derecho a conocer el origen genético. Analizamos el dilema entre el texto de la ley, que propicia la comunicación del origen genético al nacido mediante dichas técnicas, y los factores subjetivos que gravitan en la decisión de dar a conocer la información o guardar el secreto. En consecuencia, planteamos que la revelación del origen genético constituye una decisión ética que requiere asumir una responsabilidad subjetiva. Para abordar una problemática de tal complejidad ponemos a dialogar los datos relevados por dos estudios empíricos, con aportes teóricos tomados del Derecho, la bioética narrativa, la antropología y el psicoanálisis.Assisted reproduction techniques, in particular of heterologous type, open a variety of issues in the intersection of science, rights and subjectivity. In this paper we focus on the relation between the recently approved Argentinian legislation and the responses given by users of heterologous techniques —in this case, oocyte donation— with regard to the right to know the genetic origin. We analyse the dilemma between the law, which promotes the communication of the genetic origin to the subject born by such techniques, and the subjective factors that gravitate in the decision either to disclose the information, or keep it as a secret. Consequently, we argue that the disclosure of the genetic origin is an ethical decision, which requires the assumption of subjective responsibility. To deal with such a complex issue, we cross the data obtained in two empirical studies with theoretical contributions from legal studies, narrative bioethics, anthropology and psychoanalysis.As técnicas de reprodução humana assistida, e em particular as heterólogas, apresentam uma série de problemas que se localizam no cruzamento tripartite da ciência, do direito e da subjetividade.
