We assess the usefulness of stochastic redistribution among a continuum of risk-averse agents with quasilinear utilities in labor. Agents differ according to their consumption tastes, which remain private information. We identify circumstances where stochastic redistribution is socially...

This paper studies relationships between the local determinacy of a stationary equilibrium in the perfect foresight dynamics, and its local stability in dynamics arising from econometric learning procedures. There is no clear links in linear scalar economieds where agents forecast only one...

This paper studies the relationships between determinacy and stability under recurdive learning of rational expectations equilibria. The analysis is carried out within a non-stochastic linear temporary general equilibrium framework with predetermined variables (or memory). Determinacy of the...

This paper analyses an example of nonstationary stochastic endogenous fluctuations. It studies the existence of Markovian sunspot equilibria on the rates of growth in a linear one step forward looking economy with one predetermined variable. It is shown that asymptotically stable stochastic...

Bubble solutions of rational expectations models are identified by extra components that arise in addition to market fundamentals. In general there still exist many equilibrium paths relying on a minimal set of state variables, i.e., along which the number of lags that influence the current...

This paper studies relationships between the determinacy of a stationary equilibrium in the perfect foresight dynamics, and its local stability in dynamics arising from econometric learning procedures. There is no clear links in linear scalar economies where agents forecast only one perods...

Consider a simple general equilibrium economy with one representative consumer, a single competitive firm and the government. Suppose that the government has to finance public expenditures using linear consumption taxes and/or a lump-sum tax on profits redistributed to the consumer. We show...

In a second best environment, the optimal policy choice sometimes follows the first best rules. This note lays down the information structure and separability assumptions under which this property holds in a variety of setups.
