This paper analyses the effects of transitory increases in government spending when public debt is used as liquidity by the private sector. Aggregate shocks are introduced into an incomplete-market economy where heterogenous, infitely-lived households face occasionally binding borrowing...

This paper uses a stylised asset-pricing model to show that sunspots may cause asset returns to be predictable, a widely documented feature of many speculative markets. This result parallels and extends previous works showing that sunspots render asset prices excessively volatile.

This paper analyses the dynamic implications of an asset-pricing model with incomplete participation due to entry costs. It is shown that heterogeneity in entry costs can lead to the existence of multiple stochastic sunspot equilibria, whereby the number of agents in the market and asset prices...

Financial crisis are often associated with an endogenous credit reversal fol- lowed by a fall in asset prices and failures of financial institutions. To account for this sequence of events, this paper constructs a model where the excess risk-taking of portfolio investors leads to a bubble in...

This paper analyses the effects of money shocks on macroeconomic aggregates in a tractable flexible-price, incomplete-markets environment that generates persistent wealth inequalities amongst agents. In this framework, current inflation redistribute wealth from the cash-rich employed to the...

This paper analyses the e¤ects of money shocks on macroeconomic aggregates within a flexible price, incomplete markets environment that generates persistent wealth inequalities amongst agents. In this framework, unexpected money shocks redistribute wealth from the cash-rich employed to the...

This paper analyses the dynamics and welfare properties of a simple AK endogenous growth model with intersectoral capital externalities. When externalities are sufficiently large, the model generates multiple growth trajectories all convergingtowards the (unique) balanced growth path. Solving...
