There is by now a large consensus in modern monetary policy. This consensus has been built upon a dynamic general equilibrium model of optimal monetary policy as developed by, e.g., Goodfriend and King (1997), Clarida et al. (1999), Svensson (1999) and Woodford (2003). In this paper we extend...

In a series of papers, Benhabib, Schmitt-Grohé and Uribe (2001a, 2001b, 2001c, 2002 and 2004) have shown that active interest rules may lead to very unexpected consequences: indeterminacy, deflation traps, large cyclical instability, and can even lead to chaotic dynamics under standard sets of...

We explore the dynamic behavior of a New Keynesian monetary policy problem with expectations formed, partially, under adaptive learning. We consider two alternative cases: on the first setting, the private economy has the ability to predict rationally real economic conditions (the output gap)...

Until very recently, the pervasive existence of models exhibiting well-defined backward dynamics but ill-defined forward dynamics in economics and finance has apparently posed no serious obstacles to the analysis of their dynamics and stability, despite the problems that may arise from possible...

The New Keynesian model has recently been subject to two serious criticisms: the model cannot produce plausible inflation and output dynamics following a monetary shock, and the stability of its dynamics suffers from indeterminacy. The procedures that have been proposed to eliminate these two...

We show that very complicated dynamics arising, e.g. from an overlapping generations model (OLG) with production and an endogenous intertemporal decision between labour and leisure, which produces hyperchaos (both eigenvalues with modulus higher than 1), can in fact be controlled or managed with...

The main aim of this paper is to analyse the dynamics of nonlinear discrete-time maps generated by duopoly games with heterogeneous and quadratic cost functions, in which players do not form expetations about the rival’s actions accordingto the ratioal expectations hypothesis. We discusse here...

In this paper we apply the techniques of symbolic dynamics and chaos control to the analysis of a labor market model which shows chaotic behavior and large volatility in employment flows. The possibility that chaotic dynamics may arise in modern labor markets had been totally strange to...

This paper analyzes the dynamic properties of a standard New Keynesian monetary policy model when private agents expectations are assumed to be formed under a learning mechanism. As pointed out in the literature, learning with decreasing gain estimators tends to lead to convergence to the...
