Abstract This paper studies the evolution of the monetary policy transmission mechanisms in the US after the financial crisis and the extraordinary monetary stimulus applied since 2008. The implementation of a modified Dynamic Factor Model allows the identification of two different structural scenarios based on the information contained in a large dataset of 110 variables….
Brazil is proportionally a relatively unimportant player in the world fisheries scenario. However, small-scale fisheries (SSF) specifically are crucial for local livelihoods and the food security of millions of people, both on the coast and inland. Such fisheries provide more than 50% of the total Brazilian catches, suggesting that they can be highly impacting on…
Abstract In a two-sector economy, we consider the endogenous determination of the level of competition in the imperfectly competitive sector, under democratic, non-manipulated voting. In the context of the Salop’s (1979) circular model, we identify conditions such that besides a competitive equilibrium (with most voters choosing the efficient level of transport cost), a “populist” equilibrium…
Abstract What are the implications of legal rules for growth and business expansion? This question has been at the center of the rich literature that explores the link between legal institutions and economic performance. While the scholarship has provided insights on the differential experience of countries which developed their own legal systems and those that…
Abstract During the last years, interest on hybrid metaheuristics has risen considerably in the field of optimization and machine learning. The best results found for many optimization problems in science and industry are obtained by hybrid optimization algorithms. Combinations of optimization tools such as metaheuristics, mathematical programming, constraint programming and machine learning, have provided very…
Abstract An effective climate agreement is urgently required, yet conflict between parties prevails over cooperation. Thanks to advances in science it is now possible to quantify the global carbon budget, the amount of available cumulative CO2 emissions before crossing the 2oC threshold (Meinshausen et al., 2009). Countries carbon claims, however, exceed this. Historically such situations have been tackled…
Resumen El trabajo examina la evolución de la “desigualdad nutricional” a largo plazo en Argentina. Definimos la “desigualdad nutricional” como las diferencias inter-personales al acceso a la nutrición y la salud en primera infancia. Este ensayo presenta los resultados de varias muestras de población (reclutas y presos) de diversas regiones de la Argentina. La pregunta…
Abstract Much biodiversity is found in farm land. However, there is usually a trade-off between farm land productivity and sustainability of natural resources. Biodiversity conservation in agricultural land usually requires to carry on a series of conservationist practices that are costly. Therefore, farmer’s participation in conservationist programs requires economic incentives. Our goal is to identify…
Abstract In the current presentation, I intend to extend the developments in Kruger, Ngai & Théra, SIAM J. Optim. 20(6), 3280-3296 (2010) and, more precisely, to characterize, in the Banach space setting, the stability of the local and global error bound property of inequalities determined by proper lower semicontinuous under data perturbations. I will propose…
Abstract: By using robustness methods we design HCRs that explicitly include scientific uncertainty. Under scientific uncertainty –when the perceived model can be generated by a nearby operating model– robust HCRs are designed assuming that the (inferred) operating model is more persistent than the perceived model. As a result, a robust HCR has a steeper ratio…
