We characterise optimal tax policies when the government has access to consumption taxation and cannot credibly commit to future policies. We consider a neoclassical economy where factor income taxation is distortionary within the period, due to endogenous labour and capital utilisation and...

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...

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...

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...

While consumption habits have been utilised as a means of generating a hump shaped output response to monetary policy shocks in sticky-price New Keynesian economies, there is relatively little analysis of the impact of habits (particularly, external habits) on optimal policy. In this paper we...
