We consider the stability under adaptive learning of the complete set of solutions to the model when . In addition to the fundamentals solution, the literature describes both finite-state Markov sunspot solutions, satisfying a resonant frequency condition, and autoregressive solutions depending...

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...

Equilibrium models with heterogeneous agents and aggregate uncertainty are difficult to analyze since policy functions and market prices depend on the cross-sectional distribution over agents' state variables which is generally a high-dimensional object. This paper develops and applies a general...

We describe and compare the experiences of academic exclusion of Alexander Del Mar, J.A. Hobson, and Gordon Tullock. While aspects of the circumstances differed, a common element was academic exclusion because of challenges to mainstream views. Alexander Del Mar, J.A. Hobson, and Gordon Tullock...

Fiscal consolidation literature often neglects that there are economies with a sizable underground sector and that most of time it is accounted in GDP statistics. This produces non negligible effects on fiscal multipliers. This paper explores a fiscal consolidation plan calling for a downsizing...

This paper investigates the effects of uncertainty on the macro economy by replicating its micro effects on individual subjective beliefs. In our model, the representative household has smooth ambiguity preferences and is uncertain about which scenario the economy will be in the next period:...

Properties of dynamic stochastic general equilibrium models can be revealed by either using numerical solutions or qualitative analysis. Very precise and intuition-building results are obtained by working with models which provide closed-form solutions. Closed-form solutions are known for a...

I distinguish two types of macroeconomic models. The first type are top-down models in which some or all agents are capable of understanding the whole picture and use this superior information to determine their optimal plans. The second type are bottom-up models in which all agents experience...

We describe an algorithm that is able to compute the solution of a singular linear difference system under rational expectations. The algorithm uses the Generalized Schur Factorization and is illustrated by a simple example. -- stochastic dynamic general equilibrium ; linear solution methods ;...
