A financial stability fund set by a union of sovereign countries (e.g. the European Stability Mechanism), can improve countries's ability to borrow and lend, and to share risks, with respect to debt financing. Efficiency gains arise from the ability of the fund to offer long-term financial...

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...

is monotone in output. We also investigate a few possibilities of relaxing these requirements.

Several frictions might prevent (or make undesirable) the full taxation of savings. Due to international capital mobility, for instance, the government may not have perfect control over agent's saving and consumption decisions. We show in this paper that a restricted ability to tax savings has...

In a model with capital accumulation, aggregate risk and competitive intermediaries, Abraham and Carceles-Poveda (2006) show that the constrained efficient allocations can be decentralized as a competitive equilibrium with endogenous borrowing limits if one also imposes an upper limit on the...

We study the extent to which self-referential adaptive learning can explain stylized asset pricing facts in a general equilibrium framework. In particular, we analyze the effects of recursive least squares and constant gain algorithms in a production economy and a Lucas type endowment economy....

Several frictions restrict the government's ability to tax assets. First of all, it is very costly to monitor trades on international asset markets. Moreover, agents can resort to non-observable low-return assets such as cash, gold or foreign currencies if taxes on observable assets become too...
