Earlier studies of the seigniorage inflation model have found that the high-inflation steady state is not stable under adaptive learning. We reconsider this issue and analyze the full set of solutions for the linearized model. Our main focus is on stationary hyperinflationary paths near the...

An economy exhibits structural heterogeneity when the forecasts of different agents have different effects on the determination of aggregate variables. Various forms of structural heterogeneity can arise and we study the important case of economies in which agents' behavior depends on forecasts...

We develop a monetary model with flexible supply of labor, cash in advance constraints and government spending financed by seignorage. This model has two regimes. One regime is conventional with two steady states. The other regime has a unique steady state which can be determinate or...

We consider the stability under adaptive learning of the complete set of solutions to the basic linear forward looking model in which the current value of the state variable depends linearly on the (subjectively) expected value of the state next period and the coefficient of the expected state...

We examine the nonlinear one-step forward-looking model, in which the current state is a function of the (subjective) expected value of a nonlinear function of the state next period. Stationary Markov Sunspot Equilibria (SSEs) are known to exist near an indeterminate steady state, i.e. when the...

This paper discusses the concept of path dependence in macrodynamics, and identifies practical difficulties associated with building path-dependent macrodynamic models of the sort that Keynesians and Schumpeterians regard as necessary for the successful study of long-term growth and development....

We construct a multi-agent system (MAS) model of cyclical growth in which aggregate fluctuations result from variations in activity at firm level. The latter, in turn, result from changes in “animal spirits” or the state of long run expectations (SOLE) and their effect on firms’ investment...

This paper contributes to the debate about whether or not inflation targeting is compatible with Post Keynesian economics. It does so by developing a model that takes into account the potentially inflationary consequences of interest rate manipulations. Evaluations of the macroeconomic...

Throughout his career, Malcolm Sawyer has both encouraged and contributed to the development of a Kaleckian alternative to conventional macroeconomic theory. In the spirit of this endeavour, we construct a Keynes-Kalecki model of cyclical growth with agent-based features. Our model is driven by...

We develop a neo-Kaleckian growth model that emphasizes the importance of consumption behavior. In our model, workers first make consumption decisions based on their gross income, and then treat debt servicing commitments as a substitute for saving. Workers' borrowing is induced by their desire...
