Factor saving innovations and factor income shares

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

Revisiting the Relationship between Income Distribution and Economic Growth

La mayoría de los modelos que exploran la relación entre la desigualdad en la distribución del ingreso y el crecimiento económico, postulan la existencia de una correlación negativa entre las dos que es generada a través de diferentes mecanismos. Paralelamente a los modelos teóricos, un número importante de estudios empíricos han tratado de evaluar esta relación. De este esfuerzo ha surgido un consenso amplio que valida la existencia de dicha relación negativa. No obstante, estudios recientes basados en el uso de datos de panel han producido el resultado contrario, documentando la presencia de una relación positiva entre desigualdad y crecimiento. El examen del debate generado a partir de estos resultados, así como el trabajo empírico adelantado en este estudio, indican que las estimaciones obtenidas en diversos trabajos pueden no ser tan robustas como se creía En consecuencia, se sugiere que la realización de estudios de caso por país puede ser una mejor vía para explorar este tema.

Essays on International trade and economic growth

At present, we are witnessing globalization as a truly worldwide phenomenon. Trade agreements among differing countries, a reduction in trade costs, the mobility of production factors, the free flow of information and so on are all proof of the present day era of globalization. Countries are trading with one another more and more every day and the effects of international trade on economies represent a central discussion in all economic spheres. In spite of increasing trade around the world and the promotion of globalization by multilateral organisms such as WTO and IMF, the effects of international trade are not yet clear. Economics literature concerning the effects of international trade on economic growth and welfare remains ambiguous in terms of both theoretical models and empirical research. The present thesis tries to contribute to the theoretical debate surrounding the effects of dynamic international trade, focusing in particular on the implications for economic growth, welfare and changes in the preferences of individuals.

Etnic discrimination and income in San Andrés Island, Colombia

This document examines, bases on the analysis of observable characteristics, if an income gapexists between the raizal population and non raizal population of San Andres Island. For thispurpose, the information of the SISBEN II survey for the year 2004, compelled by the NationalPlanning Department (DNP, Spanish acronym) is used. The methodological strategy uses quantileregressions to determine the existence of pay gaps throughout the distribution of income. Theresults suggest that being raizal has a negative impact on income for the lower quantiles. However,this difference vanishes as income increases, becoming positive at higher levels.

Involvement in environmental causes, does the joint effect between subjective income and the performance of the country matter?

Previous research has shown that richer people are more likely to engage in an environmentalcause. We extend it by considering the joint effect between subjective income and a set of macroeconomicvariables. For doing so, we employ the fifth wave of the World Values Survey (WVS).This study provides clear evidence that even when both factors matter, people´s attitudes cruciallydepend on the interaction effect. Hence, those measures that affect the characteristics of thecountry would also change the disposition to be involved.

Subsurface drip irrigation emitter spacing effects on soil water redistribution, corn yield and water productivity

Emitter spacings of 0.3 to 0.6 m are commonly used for subsurface drip irrigation (SDI) of corn on the deep, silt loam soils of the U.S. Great Plains. Subsurface drip irrigation emitter spacings of 0.3, 0.6, 0.9 and 1.2 m were examined for the resulting differences in soil water redistribution, corn grain yield, yield components, seasonal water use, and water productivity in a 4‐year field study (2005 through 2008) at the Kansas State University Northwest Research‐Extension Center, Colby, Kansas. The results indicate that there is increased preferential water movement along the dripline (parallel) as compared to perpendicular to the dripline and that this phenomenon partially compensates for wider emitter spacings in terms of soil water redistribution. Corn yield and water productivity (WP) were not significantly affected by the emitter spacing with application of a full irrigation regime

Estratègies de finançament dels municipis turístics i competitivitat: el cas dels municipis catalans

La problemàtica del finançament dels municipis turístics és un assumpte present en el món local des de fa anys, tot i que no ha trobat una adequada resposta. Aquest treball pretén avaluar si les finances locals representen un problema per l'activitat turística i quines serien les possibles solucions. L'estudi de les característiques dels municipis turístics permet constatar les importants repercussions sobre el territori que comporta la gran concentració geogràfica del turisme, com el ràpid creixement demogràfic d'aquest municipis i un important augment dels habitatges. Dels resultats de la investigació es desprèn que els municipis turístics no tenen ni unes despeses, ni uns ingressos per càpita superiors als dels no turístics. Conseqüentment, tampoc presenten problemes de dèficit especials. El que es produeix és una redistribució interna de la despesa en perjudici de la despesa amb una baixa vinculació amb el turisme, que bàsicament té per destinatària la població resident

Implications for early interventionists: Cross-cultural and low-income family differences

This study examined the existing literature on current early intervention processes for children who are deaf or hard of hearing who are from low-income or minority families. The review of literature includes a framework of understanding the dynamics of low-income households and cultural differences among African Americans, Latin Americans, and American Indians.

Hacia la definición de una línea de codicia: aportes conceptuales y empíricos sobre América Latina y Ecuador (Tema Central)

Este ensayo propone la línea de codicia para controlar el máximo nivel de consumo ética y económicamente aceptable, sobre el cual una redistribución parcial de los ingresos individuales puede eliminar la pobreza y restituir la economía hasta sus límites sustentables. El crecimiento económico actual permite superar varias veces las necesidades fundamentales de la población, sin embargo, la enorme inequidad social impide que al menos el 40% de la humanidad satisfaga sus necesidades humanas básicas, mientras que, el consumo suntuario absorbe una parte significativa del producto mundial y el tamaño de la economía ha superado la capacidad de reposición del planeta. La línea de codicia puede ser constante en un contexto histórico nacional definido, pero es variable a escalas temporales y regionales más amplias, su nivel es menor a mayor inequidad o pobreza, y a mayor actividad económica globalmente insustentable, finalmente, aumenta conforme la economía crece dentro de límites sustentables y equitativos.
