This paper proposes conditions for the existence and uniqueness of solutions to systems of linear differential or algebraic equations with delays or advances, in which some variables may be non-predetermined. These conditions represent the counterpart to the Blanchard and Kahn conditions for the...

This paper demonstates the existence of a finite set of equilibria in the case of the indeterminacy of linear rational expectations models. The number of equilibria corresponds to the number of ways to select n eigenvectors among a larger set of eigenvectors related to stable eigenvalues. A...

In this paper, several flaws of the basic no-capital/labor-only New Keynesian model are discussed. Some flaws were left undiscovered because mass of varieties n in Dixit-Stiglitz aggregator is often considered as not affecting overall outcomes. Only when n=1 would ordinary results of the basic...

In these notes I go over some basic aspects of the analysis of business cycles and aggregate fluctuations from a dynamic stochastic general equilibrium (DSGE) perspective. I build a cannonical DSGE model with a small number of representative agents and a large set of distortionnary wedges...

This paper develops a non-equilibrium dynamic model (NEDyM) with Keynesian features (it allows for a disequilibrium between output and demand and it considers a constant marginal propensity to consume), but where production is undertaken under plain neoclassical conditions (a constant returns to...

The paper demonstrates possibilities of both convergence to the steady state and emergence of stable growth cycles around it in a simple macrodynamic model of debt-financed investment-led growth. The growth cycles are robust and are generated endogenously, either due to the existence of a...

This paper demonstrates the diverse dynamical possibilities arising out of a simple macroeconomic model of debt-financed investment-led growth in the presence of interest rate rules. We show possibilities of convergence to steady state, growth cycles around it as well as various complex...
