We characterise optimal fiscal policies when the government has access to consumption taxation but cannot credibly commit to future policies, in a calibrated Real Business Cycle model of the United States economy. Contrary to the case where only labour and capital income are taxed, the optimal...

In the typical model of risk sharing with limited commitment (e.g. Kocherlakota, 1996) agents do not have access to any technology transferring resources intertemporally. In our model, agents have a private (non-contractible and/or non-observable) saving technology. We first show that, under...

This paper studies the role of preference and income risk heterogeneity when risk sharing is partial due to limited commitment. I estimate the dynamic contract determining self-enforcing insurance transfers in a structural manner, and allow the coefficient of relative risk aversion and...

We extend the model of risk sharing with limited commitment (Kocherlakota, 1996) by introducing both a public and a private (non-contractible and/or non-observable) storage technology. Positive public storage relaxes future participation constraints and may hence improve risk sharing, contrary...

We study Ramsey monetary and fiscal policy in a small scale New Keynesian<br/>model where government spending has intrinsic value, public debt is<br/>state-noncontingent and the fiscal authority is constrained by using<br/>distortive taxation. We show that Ramsey policy is remarkably altered when<br/>consumption...

t has been shown that under perfect competition and a Cobb-Douglas production function, a basic real business cycle model may exhibit indeterminacy and sunspots fluctuations when income tax rates are determined by a balanced-budget rule. This paper introduces in an otherwise standard real...

We study the normative implications of a New Keynesian model featuring intersectoral trade of intermediate goods between two sectors that produce durables and non-durables. The interplay between durability and sectoral production linkages fundamentally alters the intersectoral stabilization...

This paper contributes to a recent debate about the structural and institutional<br/>conditions under which discretionary monetary policy-making may be superior to<br/>timeless perspective. To this end, we formulate an input-output economy in which firms technology employs both labor and intermediate...
