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)...

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...

This paper examines the use of exclusive dealing agreements to prevent the entry of rival firms. An exclusive dealing agreement is a contract between a buyer and a seller where the buyer commits to buy a good exclusively from the seller. One main concern of the literature is to explain how an...

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...

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...

This paper examines and compares the impact on growth of government’s funding national R&D or providing a tax rate reduction for foreign investment in R&D. In an innovationbased model we show the relation between the costs of these two policies. One meaningful policy implication of our results...

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...

Czech Republic, Hungary, and Poland are set to join the European and Monetary Union (EMU) in the near future. This paper offers a framework for the quantitative evaluation of the economic costs of joining the EMU. Using an open economy dynamic general equilibrium model with sticky prices, we...

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 with sticky prices a la Calvo and forward looking behavior. In this paper we extend this standard model by introducing nonlinearity into...
