Models dealing with monetary policy are generally based on microfoundations that characterize the behaviour of representative agents (households and firms). To explain the representative consumer behaviour, it is generally assumed a utility function in which the intertemporal elasticity of...

This paper shows that the evolutionary process of spatial agglomeration in multi-regional core-periphery models can be explained analytically by a much simpler method than the continuous space approach of Krugman (1996). The proposed method overcomes the limitations of Turing's approach which...

We provide an analytical approach that facilitates understanding the bifurcation mechanism of a wide class of economic models involving spatial agglomeration of economic activities. The proposed method overcomes the limitations of the Turing (1952) approach that has been used to analyze the...

This article analyses the dynamics of an overlapping generations economy (Diamond, 1965) with pay-as-you-go financed public pensions and myopic expectations. It is shown that large PAYG pensions triggers economic fluctuations depending on the mutual relationship between technology and preference...

We explore bifurcation phenomena in the open-economy New Keynesian model developed by Clarida, Gali and Gertler (2002). We find that the open economy framework can bring about more complex dynamics, along with a wider variety of qualitative behaviors and policy responses. Introducing parameters...
