This paper presents the state of art in optimal fiscal policy, focusing on the more promising research lines in this topic. In particular, we show the main results on how the government must implement optimal fiscal policy in different frameworks: from static to dynamic stochastic settings and,...

We show that in a simple growth model, where public consumption enters the utility function, and under constant returns to scale in production, the competitive equilibrium can be undetermined. Indeterminacy of equilibria arises for plausible values of the elasticity of intertemporal substitution...

En este trabajo se presenta el estado actual de conocimiento del problema de la política fiscal óptima, así como hacia dónde se dirigen las líneas de investigación en este área. En particular se describen los principales resultados derivados de cómo un gobierno debería ejecutar la...
