Newkeynesian models for monetary policy analysis under sticky prices

In literature, several works are focused on monetary policy models whose aim is the analysis of the stability of systems where private sector expectations are involved. The macroeconomic context is represented by a forward-looking model, derived from a dynamic stochastic general equilibrium framework where the agents behave optimally. The largest part of these models are presented as a simplified version of a more general context, obtained by log-linearizing the equilibrium relations in order to study small fluctuations around the steady-state. This book, departing from this starting point, tries to go beyond the log-linearized model, providing a nonlinear framework in order to establish the conditions for a unique path converging to the steady-state stationary solution, either the so called determinacy.
