We study the infinite horizon model of household portfolio choice under liquidity constraints and revisit the portfolio specialization puzzle for impatient consumers with access to riskless and risky assets. We consider a labour income process that allows us to decompose the consumption and...

The paper develops two economic grounds for gradualism in the context of the Russian move towards a market economy: one for the support of output through subsidies, another for similar support through credit. The first argument relates to the usual case for softening the blow to a sector hit by...

International financial integration allows countries to become net creditors or net debtors with respect to the rest of the world. In this Paper, we show that a small set of fundamentals shifts in relative output levels, the stock of public debt and demographic factors can do much to explain the...

Consumption is striking back. Some recent evidence indicates that the well-known asset pricing puzzles generated by the difficulties of matching fluctuations in asset prices with high frequency fluctuations in consumption might be solved by considering consumption in the long-run. A first strand...

This Paper compares the dynamic impact of fiscal policy on macroeconomic variables implied by a large class of general equilibrium models with the empirical results from an identified vector autoregression. In the data we find that positive innovations in government spending are followed by...

This Paper studies a general equilibrium economy in which agents have the ability to invest in a risky technology. The investment risk cannot be fully insured with optimal contracts because shocks are private information. We show that the presence of investment risks leads to under-accumulation...

Despite being the standard growth model for several decades, little is actually known analytically about the dynamic properties of the neoclassical Ramsey-Cass-Koopmans growth model. This paper derives analytically the properties of the endogenous saving rate when technology takes the Constant...

In dynamic stochastic welfare comparisons, a failure clearly to distinguish between risk aversion and intertemporal substitutability can result in misleading assessments of the impact of risk aversion on the welfare costs of consumption-risk changes. The problem arises in any setting in which...

This paper is an attempt to provide an updated assessment of what we know and what do not know about the impact of monetary policy on the economy and what implications follow for the conduct of monetary policy in today's world. Firstly, we discuss the conditions under which monetary policy can...
