In this paper we study the impact of moral hazard in labor contracts on the cross-sectional wage distribution, in particular, its effect on the extent of residual wage inequality. The tool of our analysis is a search model with job-to-job mobility and firm competition for workers. In our...

We provide a characterization of the optimal UI scheme in the presence of layoff risk and hidden wealth. The optimal transfer scheme we propose is such that unemployed agents are liquidity constrained and re-employment taxes are independent of previous employment history. Past history is however...

In this paper we analyze analytically, quantitatively, and empirically a framework where labor supply has three distinct roles. First, as usual, it increases contemporaneous earnings. Second, because of incomplete asset markets, it provides some partial insurance for idiosyncratic labor...

This paper applies the insights of the literature on idiosyncratic shocks to inividual labor productivity to the dynamics of plant-level total factor productivity. Recent work in I.O. has emphasized the importance of firm- and plant-level heterogeneity in total factor productivity. Most of the...

The present project introduces the possibility of default on the trading contracts in an infinite horizon incomplete markets model, relaxing the usual assumption made in the literature with respect to the trading limits, which are chosen to be fixed or independent of the characteristics of the...

In environments where agents face uninsurable idiosyncratic income shocks, it is well-known that progressive taxation can potentially provide extra insurance and may, hence, improve welfare. However, if taxes distort individual incentives or cannot be conditioned on all relevant individual...

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...

This paper studies different income tax reforms in an infinite horizon economy with a progressive labor income tax code, incomplete markets an endogenous borrowing constraints on capital holdings. In particular, it assumes that households can break their trading arrangements by going into...
