Small firms encounter difficulties in raising external finance owing to greater information problems. For small innovative firms, whose activity is more difficult to evaluate, the cost of external finance could be even higher. This paper examines special features of the financial structure of...

I show how cyclical aggregate shocks can stimulate structural reallocation activities, which in turn amplify the effect of the shock. I emphasize the informational aspects related to restructuring activities and their potential interplay with aggregate shocks. Building on work by Caplin and...

This paper builds a dynamic model of the information flow between partially informed financial institutions and a public agency. The financial institutions decide how to allocate their portfolio between a risk-free technology with a known payoff and a risky technology whose payoff is unknown....

Under the assumption of bounded rationality, economic agents learn from their past mistaken predictions by combining new and old information to form new beliefs. The purpose of this paper is to examine how the policy-maker, by affecting private agents' learning process, determines the speed at...

We study the impact of the publication of central banks� macroeconomic projections on the dynamic properties of an economy where (i) private agents have incomplete information and form their expectations using recursive learning algorithms; (ii) the short-term nominal interest rate is set...

We study an endowment economy with complete markets and heterogeneous agents who do not have rational expectations, but form their beliefs using adaptive learning algorithms that may differ from one individual to another. We show that market completeness allows agents to smooth consumption...

We derive the optimal fiscal policy for a government that is committed to honoring its debt but faces investors which fear a sovereign default. We assume that investors are able to learn from new evidence, as in Marcet and Sargent (1989), so that they can gradually correct their overly...

We study firms� incentives to acquire costly information in booms and recessions to understand the role of endogenous information in explaining business cycles. We find that when the economy has been in a recession in the previous period, and firms enter the current period with a...

We analyse a simplified New-Keynesian model with an unobserved aggregate cost-push shock in which firms and the central bank have different information about the shock. We consider a linear policy rule where a pure inflation targeting central bank decides how much to react to the shock given its...
