description: El objetivo de este documento es presentar una descripción de la relación de Estado y Mercado en los autores clásicos. En general, hay un acuerdo en la importancia que tiene el mercado para el funcionamiento de la economía. Sin embargo, la metáfora de la mano invisible o del laissez-faire ha llevado a minimizar la importancia que autores como Adam Smith y David Ricardo le otorgaron al Estado en sus escritos. Frente a esto, es importante resaltar la relación entre Estado y Mercado en los autores que estuvieron en el inicio de la Economía Política.
Information externalities and export trade duration at the firm level

description: Recent empirical work emphasizes the importance of the extensive margin of trade (new exporters, new export activities) for long run export growth. In this context, understanding the determinants of duration of new exporters is key for underpinning the dynamics of exports growth. As new exporters tend to show low survival rates, identifying the determinants of export duration is highly relevant for academic and policy purposes. In this paper, we explore whether information externalities arising from different levels of spatial interaction allow new exporters to increase the duration of their trade activities. For this, we use transaction level data on Colombian exports between 2004 and 2011. Results show that export networks, understood as the agglomeration of exporting firms at different spatial levels, reduce the risk of dropping out from exporting and that this effect is stronger the more similar are export activities carried out by firms
Health care network formation and policyholders' welfare
Creators: name: Bourgeon, Jean-Marc

Publisher: name: Universidad del Rosario
Year: 2022

description: We develop a model in which two insurers and two health care providers compete for a fixed mass of policyholders. Insurers compete in premium and offer coverage against financial consequences of health risk. They have the possibility to sign agreements with providers to establish a health care network. Providers, partially altruistic, are horizontally differentiated with respect to their physical address. They choose the health care quality and compete in price. First, we show that policyholders are better off under a competition between conventional insurance rather than under a competition between integrated insurers (Managed Care Organizations). Second, we reveal that the competition between a conventional insurer and a Managed Care Organization (MCO) leads to a similar equilibrium than the competition between two MCOs characterized by a different objective i.e. private versus mutual. Third, we point out that the ex ante providers’ horizontal differentiation leads to an exclusionary equilibrium in which both insurers select one distinct provider. This result is in sharp contrast with frameworks that introduce the concept of option value to model the (ex post) horizontal differentiation between providers.

Acción colectiva y políticas públicas

Publisher: name: Universidad del Rosario
Year: 2022

description: El presente documento hace una revisión de la literatura reciente (últimos 15 años) que vincula la acción colectiva con las políticas públicas. En particular se observan dos tendencias, de un lado, la defensa a la lógica de la acción colectiva señalando el tipo de incentivos que se deben crear para propiciar la cooperación y eventualmente tener resultados de políticas públicas, y aquellos que piensan que la acción colectiva depende de elementos psicológicos y sociales que no siempre garantizan una cooperación constante y que dificultan predecir lo que puede suceder en términos de políticas públicas. Al final se concluye que, si bien la lógica de la acción colectiva contribuye al análisis de las políticas públicas, aún falta un mejor entendimiento de las razones que motivan o frenan la cooperación y la manera como esta se construye en función de un problema colectivo que se puede o no convertirse en una política pública.

El ejercicio se realiza desde dos perspectivas: una nacional, partiendo de resultados previos de DANE (2011) que relaciona información de la muestra cocensal 2005 con información catastral a nivel nacional; y una segunda toma al Distrito Capital aparte, utilizando directamente el avalúo catastral como variable básica de clasificación. Se explora adicionalmente la posibilidad de obtener un número de estratos óptimo de manera endógena, que resulta en esta oportunidad en nueve grupos.

Does the unemployment benefit institution affect the productivity of workers? evidence from a field experiment
Creators: name: Dalton, Patricio
name: Blanco, Mariana

Publisher: name: Universidad del Rosario

description: We investigate whether and how the type of unemployment benefit institution affects productivity. We designed a field experiment to compare workers’ productivity under a welfare system, where the unemployed receive an unconditional monetary transfer, with their productivity under a workfare system, where the transfer is received conditional on the unemployed spending some time on ancillary activities. First, we find that having an unemployment benefit institution, regardless of whether it makes transfers conditional or unconditional, increases workers’ productivity. Second, we find that productivity is higher under Welfare than under Workfare. Becoming unemployed under Welfare comes at the psychological cost of a drop in self-esteem, presumably due to the shame or stigma associated with receiving an unconditional unemployment benefit. We document the empirical relevance of precisely this channel. The differences we observe in productivity suggest that this psychological cost acts as an extra nonmonetary incentive for workers under Welfare to put a higher effort in their work.

Gender differences on sexual behavior and school inputs : evidence from Bogota

Publisher: name: Universidad del Rosario
Year: 2015

description: This paper explores the correlation between school factors and the differentiated results on sexual behavior between boys and girls in Bogota. A school stratified propensity score matching was per-formed to match each boy of the sample with the most similar girls in individual, household and school characteristics. A regression analysis was performed to estimate the correlation between school factors and the main outcomes, namely sexual status, condom use in last intercourse, teenage childbearing and age at first intercourse. Boys - in relation to girls - begin earlier their sexual life, report larger use of condom and lower incidence of teenage childbearing. These differences are correlated with sex education at school, and teacher’s characteristics age, education level and pedagogy degree. The results suggest that the content of sex education that is delivered to girls at school is not complete or accurate and that teachers play a key role to reduce this gender bias

description: El desarrollo del mercado financiero en Colombia, ha hecho que la integración con los merados financieros internacionales sea cada vez más evidente. Es por esto que el estudio del grado de relación de nuestras tasas de interés con las tasas de interés de las tasas internacionales, cobra relevancia. Este estudio, busca evidencia sobre el cumplimiento de la hipótesis de paridad descubierta de intereses y la hipótesis de expectativas racionales, a través del uso de las curvas cero cupón de Colombia y Estados Unidos, siguiendo la metodología derivada del estudio de Bekaert (2002). Se encuentra que el cumplimiento de ambas hipótesis, simultáneamente, no es un hecho común entre los diferenciales de tasas de Colombia y Estados Unidos. Además, en algunos casos, se encuentra que las hipótesis no se cumplen entre las tasas de interés de la misma nacionalidad.
Empowering IDP with SMS: a randomized controlled trial in Bogotá

description: We carried out a randomized controlled trial in Bogotá, the recipient of Colombia´s highest number of internally displaced people (IDP), to assess whether the use of SMS to communicate eligibility to social benefits fosters the welfare of victimized internal refugees. Only a fraction of IDP are elegible to benefits. We inform eligibility via SMS to a random half of IDP-households who are, and estimate the Local Average Treatment Effect of the text message on the knowledge of the benefits available tothe displaced population. We show that while on the average treated households know their rights better than controls, a more disaggregate analysis suggest that there is variation of awareness across benefits. The intervention was overall successful in empowering IDP and the use of SMS should be widened as a social policy instrument. However our results suggest that text messages should be complemented with other communication strategies, yet to be evaluated.
El lado oscuro de la equidad: violencia y equidad en el desempeño escolar

Year: 2014

description: La literatura empírica sobre el impacto de los conflictos violentos en variables educativas se ha enfocado en el impacto de la violencia sobre la acumulación de capital humano, dejando de lado otras variables relevantes como la equidad educativa. Usando la implementación empírica de Ferreira y Gignoux (2011) del marco conceptual de igualdad de oportunidades de Roemer (1998), este trabajo estima el impacto de la intensidad del conflicto armado sobre la equidad educativa en Colombia medida a través del desempeño escolar en las pruebas Saber 11 para el periodo 1997-2010. Para resolver sesgos potenciales por simultaneidad o por variable omitida se utilizan las capturas de homicidas por parte de la fuerza pública como fuente de variación exógena de la violencia en una estimación de variables instrumentales. Los resultados apuntan a que el conflicto aumenta la equidad de oportunidades en los logros educativos. Al aumentar las tasas de deserción escolar, el conflicto genera una selección positiva en términos de habilidad y esfuerzo para la fracción de estudiantes que el sistema retiene. Esto sugiere que hay que tener cautela al interpretar patrones de equidad en educación basada en resultados en lugar de procesos.

Genetic testing with primary prevention and moral hazard
Creators: name: De Donder, Philippe
name: Bardey, David
Publisher: name: Universidad del Rosario
Year: 2022

description: We develop a model where a free genetic test reveals whether the individual tested has a low or high probability of developing a disease. A costly prevention effort allows high-risk agents to decrease the probability of developing the disease. Agents are not obliged to take the test, but must disclose its results to insurers. Insurers offer separating contracts which take into account the individual risk, so that taking the test is associated to a discrimination risk. We study the individual decisions to take the test and to undertake the prevention effort as a function of the effort cost and of its e¢ ciency. We obtain that, if effort is observable by insurers, agents undertake the test only if the effort cost is neither too large nor too low. If the effort cost is not observable by insurers, they face a moral hazard problem which induces them to under-provide insurance. We obtain the counterintuitive result that moral hazard increases the value of the test if the effort cost is low enough. Also, agents may perform the test for lower levels of prevention e¢ ciency when effort is not observable
Is it always good to let universities select their students?

description: We undertake a first step to investigating a reform that has been applied in numerous universities across Europe: the right to select students. We ask to what extent this right will increase the efficiency of the university. While it seems evident that giving universities the right to select students that match best with the human capital of professors should increase efficiency measures in the productivities of students in the labor market, we point to a potentially negative efect. We argue that allowing universities to select the students they prefer can reduce the incentives of the universities to improve the human capital of their professors.
Is there a motherhood penalty? decomposing the family wage gap in Colombia
Creators: name: Zuluaga, Blanca
name: Gamboa Niño, Luis Fernando
Publisher: name: Universidad del Rosario
Year: 2011

description: The aim of this paper is to provide an estimation and decomposition of the motherhood wage penalty in Colombia. Our empirical strategy was based on the matching procedure designed by Ñopo (The Review of Economics and Statistics, 90(2), 290–299, 2008a ) for the case of gender wage gaps. This is an alternative procedure to the well-known Blinder–Oaxaca decomposition method. Using the cross-sectional data of the Colombian Living Standard Survey, the wage gap was decomposed into four components, according to the characteristics of mothers and non-mothers. Three of the components are explained by differences in observable characteristics of women, while the other is the unexplained part of the gap. We found that mothers earn, on average, 1.73 % less than their counterparts without children and that this gap slightly decreased when the group included older women. It is observed from the results that, once schooling was included as a matching variable, the unexplained part of the gap considerably decreased and became non-significant. Thus, we did not find evidence of wage discrimination against mothers in the Colombian labor market. Copyright Springer Science+Business Media New York 2013

Gender differences in time allocation of poor children in Colombia
Creators: name: Gallego, Juan M.
name: Sepulveda, Carlos E.
Publisher: name: Universidad del Rosario
Year: 2022

description: This paper studies the effect of credit constraints and constraints on transfers between parents and children, on differences in labor and schooling across children within the same household, with an application to gender. When families are unconstrained in these respects, differences in labor supply or education are driven by differences in wages or returns to education. If the family faces an imperfect capital market, the labor supply of each child is inefficient, but differences across children are still driven by comparative advantage. However, if interfamily transfers are constrained so that parents cannot offset inequality between their children, they will favor the human capital accumulation of the more disadvantaged child -generally the one who works more as a child. We use our theory to examine the gender gap in child labor. Using a sample of poor families in Colombia, we conform our predictions among rural households, although this is less clear for urban households. The gender gap is largely explained by the wage gap between girls and boys. Moreover, families with the potential to make capital transfers to adult children (e.g. those with large animals), can compensate adult sons for their greater child labor and reduced educational attainment. In such families, as predicted, the male/female labor gap is greater.

description: This paper provides new evidence on the effect of pupil’s self-motivation and academic assets allocation on the academic achievement in sciences across countries. By using the Programme for International Student Assessment 2006 (PISA 2006) test we find that both explanatory variables have a positive effect on student’s performance. Self-motivation is measured through an instrument that allows us to avoid possible endogeneity problems. Quantile regression is used for analyzing the existence of different estimated coefficients over the distribution. It is found that both variables have different effect on academic performance depending on the pupil’s score. These findings support the importance of designing focalized programs for different populations, especially in terms of access to information and communication technologies such as internet.

description: This paper presents evidence of the effect of the recent phases of the business cycle in Spain and United States, proxied by their respective unemployment rates, on the labor market of Colombian cities with high migration tradition. These countries are the main destination for labor Colombian migrants. Using information from the household survey between 2006 and 2011 for urban areas in Colombia and a differences-in-differences approach we find that unemployment rates of those countries negatively affect the probability and the amount of remittances received by Colombian households living in areas with high and moderate migration tradition. At a second stage we provide evidence that unemployment rates of those countries positively affect the labor force participation decisions in Colombian regions with the highest migration tradition.

description: La medición de la desigualdad de oportunidades con las bases de PISA implican varias limitaciones: (i) la muestra sólo representa una fracción limitada de las cohortes de jóvenes de 15 años en los países en desarrollo y (ii) estas fracciones no son uniformes entre países ni entre periodos. Lo anterior genera dudas sobre la confiabilidad de estas mediciones cuando se usan para comparaciones internacionales: mayor equidad puede ser resultado de una muestra más restringida y más homogénea. A diferencia de enfoques previos basados en reconstrucción de las muestras, el enfoque del documento consiste en proveer un índice bidimensional que incluye logro y acceso como dimensiones del índice. Se utilizan varios métodos de agregación y se observan cambios considerables en los rankings de (in) equidad de oportunidades cuando solo se observa el logro y cuando se observan ambas dimensiones en las pruebas de PISA 2006/2009. Finalmente se propone una generalización del enfoque permitiendo otras dimensiones adicionales y otros pesos utilizados en la agregación.
Factor shares at the sector level, Colombia 1990-2005

Year: 2022

description: In general, empirical studies on economics rely on the assumption of constant capital share of income both at the aggregate level and at the sector level. However, there is no empirical evidence supporting the constancy of capital share at the sector level. In this paper, using Colombian data, we measure capital share for 48 sectors during the period 1990-2005. We also explore the relation between capital's share and factor prices and the behavior of capital share during the business cycle. The main results are the following: (i) capital share is not constant but, rather, has an increasing trend; (ii) capital shares growth rates positively correlate with sector value-added growth; (iii) the capital shares behave pro-cyclically; and (iv) there is a positive correlation between capital shares and real wages and a negative correlation between capital shares and interest rates. These results suggest that the usual assumption of constant factor shares is not accurate.
Factor saving innovations and factor income shares
Creators: name: Zuleta, Hernando
Publisher: name: Universidad del Rosario
Year: 2022

description: We present an endogenous growth model where innovations are factor saving. Technologies can be changed paying a cost and technological change takes place only if the benefits are larger than the costs. Since the gains derived from factor saving innovations depend on factor abundance, biased innovations respond to changes in factors supply. Therefore, as an economy becomes more capital abundant agents try to use capital more intensively. Consequently, (a) the elasticity of output with respect to reproducible factors depends on the capital abundance of the economy and (b) the income share of reproducible factors increases as the economy grows. Another insight of the model is that in some economies the production function converges to an AK in the long run, while in others long-run growth is zero

description: In this paper we reviewed the models of volatility for a group of five Latin American countries, mainly motivated by the recent periods of financial turbulence. Our results based on high frequency data suggest that Dynamic multivariate models are more powerful to study the volatilities of asset returns than Constant Conditional Correlation models. For the group of countries included, we identified that domestic volatilities of asset markets have been increasing; but the co-volatility of the region is still moderate.

description: La reforma colombiana al sistema de salud (Ley 100 de 1993) estableció, como estrategia para facilitar el acceso, la universalidad de un seguro de salud que se adquiere mediante la cotización en el régimen contributivo o mediante la afiliación gratuita al régimen subsidiado, con la meta de cubrir a toda la población con un plan de beneficios único que comprende servicios de todos los niveles de atención. En el documento se analizan los principales hechos estilizados de la reforma en cuanto a cobertura del seguro y acceso y, mediante modelos logit, se estiman los determinantes de la afiliación y del acceso, con datos de las encuestas de calidad de vida de 1997 y 2003. Se destaca que la cobertura pasó del 20% de la población en 1993 al 60% en 2004, aunque parece imposible alcanzar la universalidad; la estructura y evolución de la cobertura muestran que los dos regímenes son complementarios, de modo que mientras el contributivo tiene mayor presencia en las ciudades y entre la población con empleo formal, el subsidiado tiene mayor peso entre la población rural y con bajos niveles de ingresos; por otra parte, el seguro tiene ventajas para la población subsidiada, con una mayor probabilidad de utilización de servicios, aunque el plan es inferior al del contributivo y existen barreras para el acceso.
Information provision in procurement auctions

Publisher: name: Universidad del Rosario
Year: 2022

description: We analyze the optimal provision of information in a procurement auction with horizontally differentiated goods. The buyer has private information about her preferred location on the product space and has access to a costless communication device. A seller who pays the entry cost may submit a bid comprising a location and a minimum price. We characterize the optimal information structure and show that the buyer prefers to attract only two bids. Further, additional sellers are inefficient since they reduce total and consumer surplus, gross of entry costs. We show that the buyer will not find it optimal to send public information to all sellers. On the other hand, she may profit from setting a minimum price and that a severe hold-up problem arises if she lacks commitment to set up the rules of the auction ex-ante.
If factor shares are not constant then we have a measurment problem. can we solve it?
Creators: name: Zuleta, Hernando
Publisher: name: Universidad del Rosario
Year: 2009

description: Recent evidence show that factor shares, if properly measured, are far from constant. Moreover, the shares of natural resources and raw labor seem to be negatively correlated with income per capita while the share of human and physical capital is positively correlated with income per capita. Now, if factor shares are not constant then (i) growth accounting exercises rely on a false assumption and (ii) there is a measurement problem. The effect that changes in factor shares have on output depend on the relative abundance of factors and, for this reason, it is necessary to have correct measures. We propose an empirical methodology to solve the measurement issue and estimate TFP growth.

description: Este documento hace un diagnostico multidimensional de las brechas regionales que existen en Colombia a nivel departamental y de su persistencia en el tiempo. Así mismo se estudian las causas de la inequidad regional. La evidencia presentada sugiere que las diferencias institucionales de largo plazo explican las desigualdades regionales actuales. Para el diagnóstico se utiliza un conjunto amplio de variables socioeconómicas incluyendo variables de ingreso y actividad económica, variables de capital humano, medidas de pobreza y desigualdad, variables de comportamiento político, variables de aislamiento geográfico, y variables de esfuerzo o dependencia fiscal. El documento también revisa algunas experiencias internacionales exitosas en la disminución de brechas regionales y plantea algunas sugerencias de política pública para el caso colombiano.

description: El análisis de la dimensión de riesgo en el estudio del desempleo, complementa el estudio de aspectos como su tipología, la importancia de la intermediación laboral o la vulnerabilidad de ciertos grupos. En este sentido, la tasa de incidencia representa un indicador compuesto que tiene en cuenta el volumen de desempleados y la persistencia en este estado mediante la incorporación de la duración media del desempleo. El análisis de la tasa de incidencia permite caracterizar de manera más completa a quienes tienen una mayor probabilidad de entrar en el desempleo o permanecer en esta situación. . Se encuentra que en Colombia existen diferencias significativas entre la tasa de desempleo y la tasa de incidencia, lo que implica que la situación del mercado de trabajo no sólo se explica por el efecto que los choques económicos tienen sobre la composición de la oferta y demanda de trabajo sino también por los fenómenos de duración en los diferentes estados laborales. Estos eventos se pueden considerar igualmente importantes para explicar la dinámica de corto y mediano plazo del mercado laboral.

description: La literatura sobre la calidad de la educación ha prestado poca atención al papel que tienen las bibliotecas públicas dentro de los determinantes del desempeño educativo. Las bibliotecas públicas son activos externos al colegio y al hogar del estudiante, pero hacen parte del entorno social que les rodea. La puesta en marcha a finales de 2001 de tres bibliotecas de gran tamaño en Bogotá, conocidas como megabibliotecas, nos permite analizar el impacto de estas iniciativas sobre la calidad de la educación en los colegios aledaños. Dicho impacto se daría a través de mecanismos adicionales a la simple reducción de costos al acceso a la información: las bibliotecas renovaron el espacio público mediante la generación de espacios agradables y amigables hacia la educación, además ofrecen regularmente actividades lúdicas dirigidas a las habitantes del sector. Aprovechando la distancia del plantel educativo a la biblioteca como una aproximación al costo de acceso a la misma, utilizando para ello Diferencia en Diferencias junto a la descomposición Blinder Oaxaca. Encontramos que las mismas parecen no tener un impacto significativo sobre el desempeño académico general en los exámenes oficiales SABER 11 durante los años posteriores a su implementación. Se recomienda analizar programas específicos que aprovechen las bibliotecas para actividades escolares y otras posibles variables de impacto como actitudes hacia el estudio y aspiraciones a la educación superior.

description: آموزش و پرورش یکی از بزرگترین نهادهایی است که در هر کشوری توجه ویژه ای به آن می شود. توجه به آموزش و پرورش از آن جهت است که هم می تواند باعث توسعه و پیشرفت و هم باعث نابودی یک کشور شود. برای همین معمولا سیستم آموزشی هر جامعه ای سعی دارد تا بهترین برنامه ریزی را برای آینده ترسیم کنند. یکی از انواع برنامه ریزی که در حرکت رو به جلوی سازمان و ترسیم وضع موجود برای رسیدن به وضع مطلوب را در نظر دارد برنامه ریزی راهبردی می باشد. با توجه به اهمیت و ضرورت تدوین برنامه ریزی راهبردی در سازمان در این تحقیق بر آن شدیم تا با روش تحلیلی- توصیفی به بررسی نقش برنامه ریزی راهبردی در آموزش و پرورش بپردازیم

description: The use of video as a teaching resource stimulates the construction of new knowledge. Although this resource exists in several
genres and media, the experience of professionals that use this resource in class is not appreciated. Furthermore, online spaces
guiding and supporting the appropriate use of this practice are unavailable. In the online learning field, a proposal has emerged
for a repository of short videos aimed at instructing how to use them as a teaching resource in order to stimulate the exchange of
ideas and experience (fostering and creating knowledge) in the teaching-learning process, which serves as a resource for professionals
in the construction of MOOCs (Massive Open Online Courses). A three-stage architecture is methodologically proposed:
identification/recognition, dissemination and collaboration in the use of videos as a teaching resource supported by an extensive
exploratory research, based on existing educational technologies and technological trends for higher education. And this leads to
the creation of a repository of Informational Content Recovery in Videos (RECIF), a virtual space for the exchange of experience
through videos. We conclude that through methodologies that facilitate the development of innovative processes and products,
it is possible to create spaces for virtual or face-to-face motivational classes (MOOCs) thereby completing an interactive and collaborative
learning toward stimulation of creativity and dynamism.

description: Objectives: Knowing the results of microbiological tests of urine samples of patients from the Rehabilitation Unit of
a regional hospital, including local data of antibiotic susceptibility.
Material and methods: We analyzed the database of the Microbiology Laboratory of the Hospital Universitario
Virgen de las Nieves with microbiological studies conducted urine samples during 2012. We investigated the etiology
and antimicrobial susceptibility of uropathogens frequently present in 143 urine samples. The 9066 survey results
voiding urine mean in Primary Care study subjects were used as controls.
Results: The 50% of neurological patients had positive urine cultures, versus 23% of controls. E. coli was the most
frequently isolated organism group neurological patients, as in the controls. Resistance studies in E. coli showed high
rates of resistance to ampicillin, cotrimoxazole, ciprofloxacin and amoxicillin with clavulanic acid.
Conclusions: E. coli is the most frequently isolated microorganism in both groups of patients studied. The antibiotic
resistance of microorganisms from the two groups have different patterns, being globally less to fosfomycin.

description: El uso de vídeos como recurso didáctico estimula la construcción de nuevo conocimiento. A pesar de la existencia de este recurso en diversos géneros y medios, no se valora la experiencia de los profesionales que lo aprovechan en clase y además no se cuenta con espacios online que orienten y apoyen el uso apropiado de esta práctica. En el ámbito del aprendizaje online, surge la propuesta
de un repositorio de vídeos de corta duración, con el objetivo de orientar acerca de su uso como recurso didáctico, a fin de incentivar un intercambio de ideas y experiencias (fomentar y crear conocimiento), en el proceso enseñanza-aprendizaje, sirviendo esto como recurso para profesionales en la construcción de los MOOC (Massive Open Online Courses). Metodológica -
mente se propone una arquitectura en tres etapas: identificación/reconocimiento, diseminación y colaboración, para el uso de
vídeos como recurso didáctico, sustentándose en una extensa investigación exploratoria, basándose en las tecnologías educativas existentes y tendencias tecnológicas para la educación superior. El resultado es la creación de un repositorio de Recuperación de Contenido de Información en Vídeos (RECIF), un espacio virtual de intercambio de experiencias por medio de vídeos. Se concluye
que por medio de metodologías que faciliten el desarrollo de procesos y productos innovadores, se pueden crear espacios de clases motivadoras, virtuales o presenciales, que completen un aprendizaje interactivo y colaborativo, estimulando la creatividad y el dinamismo.
Labor's shares - aggregate and industry: accounting for both in a model of unbalanced growth with induced innovation

description: The relative stability of aggregate labor's share constitutes one of the greatmacroeconomic ratios. However, relative stability at the aggregate level masks theunbalanced nature of industry labor's shares – the Kuznets stylized facts underlie those of Kaldor. We present a two-sector – one labor-only and the other using both capital andlabor – model of unbalanced economic development with induced innovation that canrationalize these phenomena as well as several other empirical regularities of actualeconomies. Specifically, the model features (i) one sector (goods production)becoming increasingly capital-intensive over time; (ii) an increasing relative price andshare in total output of the labor-only sector (services); and (iii) diverging sectorallabor's shares despite (iii) an aggregate labor's share that converges from above to a value between 0 and unity. Furthermore, the model (iv) supports either a neoclassical steadystate or long-run endogenous growth, giving it the potential to account for a wide range of real world development experiences.
Loan sales under asymmetric information

description: Loans are illiquid assets that can be sold in a secondary market even that buyers have no certainty about their quality. I study a model in which a lender has access to new investment opportunities when all her assets are illiquid. To raise funds, the lender may either borrow using her assets as collateral, or she can sell them in a secondary market. Given asymmetric information about assets quality, the lender cannot recover the total value of her assets. There is then a role for the government to correct the information problem using fiscal tools.
