In his seminal paper of 1928, Ramsey conjectured that if agents discounted the future differently, in the long run all agents except the most patient would live at the subsistence level. The validity of this conjecture was investigated in different environments. In particular, it has been...

This paper studies the constrained efficient intergovernmental transfer contract between the central government and the states in a federal economy. We consider an environment with moral hazard, incomplete enforceability, and date-0 negotiation costs. The interaction of moral hazard and...

This paper analyzes the dynamic properties of portfolios that sustain dynamically complete markets equilibrium when agents have heterogeneous priors. We argue that the conventional wisdom that belief heterogeneity generates continuous trade and significant fluctuations in individual portfolios...

We first study growth and risk sharing in a stochastic growth model with preference shocks and two risk-averse agents. In periods in which one of the agents needs extra consumption (insurance), it is socially optimal to reduce the consumption of the other agent (redistribution) and also to...

This paper provides an estimation of the size of income and demand automatic stabilizers in a representative sample of Latin American and Caribbean (LAC) countries. The authors find that when a negative unemployment shock hits the economy, the size of income and demand automatic stabilizers...
