This paper contains an analysis of incomplete market models with finitely but arbitrarily many heterogeneous agents. We discuss the mathematical foundation for equilibrium conditions which leads to two findings. First, we establish existence of equilibria for small and large risks. Second, we...

This paper uses a standard New Keynesian model to analyze the effects and implementation of various monetary policy frameworks in the presence of a low natural rate of interest and a lower bound on interest rates. Under a standard inflation-targeting approach, inflation expectations will be...
