The motivation of this paper is to understand the effects of coupling a macroeconomic model of inflation rate dynamics, relying on an aggregate expectation, to a heterogeneous expectations framework. A standard model composed of Okun's law, an expectations-augmented Phillips curve and an...

In this paper we integrate heterogeneous inflation expectations into a simple monetary model. Guided by empirical evidence we assume that boundedly rational agents, selecting between extrapolative and regressive forecasting rules to predict the future inflation rate, prefer rules that have...

This paper describes an application of recently developed qualitative reasoning techniques to complex, socio-economic allocation problems. We explain why we believe traditional optimization methods are inappropriate and how qualitative reasoning could overcome some of these shortcomings. A case...

In this application of an overlapping generations model the effects of a pay-as-you-go retirement scheme on the optimal savings rate, magnitude and stability of the equilibrium capital per capita level are established through the assumptions of explicit, well-behaved utility and production...

The paper formulates the fertility choice of a representative working woman in the context of a two-period OLG model. The starting point is a young working woman faced with the dilemma of having to simultaneous rear children and participate in the labor force. Discrete variable equivalents of...

We show that carefully designed central bank interventions may have a similar (stabilizing) effect on foreign exchange dynamics as transaction taxes. Transaction taxes seek to curb speculative activity. If speculators consist of chartists and fundamentalists  --  as indicated by...
