Optimal policym heterogeneity and limited commitment

Bauducco, Sofia 03 July 2009 (has links)
Esta tesis contribuye a la literatura de política fiscal y monetaria óptima. Primero analizo cómo el resultado de tasas impositivas suaves, que habitualmente se obtiene en modelos de política fiscal óptima, se ve alterado en un contexto de división internacional de riesgo con compromiso parcial. Encuentro que la presencia de compromiso parcial altera significativamente la dinámica de las variables fiscales, con respecto al caso de compromiso total. La volatilidad de la tasa impositiva aumenta. En segundo lugar, estudio la política fiscal y monetaria en un modelo con shocks idiosincráticos no asegurables a la productividad laboral. Encuentro que, cuando el gobierno es utilitarista, la autoridad monetaria fija la tasa de interés nominal a cero. Los efectos agregados de bienestar son pequeños, mientras que los efectos individuales son grandes. Los beneficiarios de la inflación son agentes pobres con baja productividad, mientras que los agentes de clase media y alta siempre son perdedores. / This thesis contributes to the literature on optimal fiscal and monetary policy. First, I analyze how the tax-smoothing result obtained in models of optimal fiscal policy is altered in a context of international risk sharing with limited commitment. I find that the presence of limited commitment alters substantially the dynamics of the fiscal variables with respect to the full commitment case. In particular, the volatility of the tax rate increases. Second, I study the optimal monetary and fiscal policy mix in a model in which agents are subject to idiosyncratic uninsurable shocks to their labor productivity. I find that, for a utilitarian government, the monetary policy-maker sets nominal interest rates to zero. Although the aggregate welfare costs of inflation are small, individual costs and benefits are large. Net winners from inflation are poor, less productive agents, while middle-class and rich households are always net losers.
