This paper studies the optimal redistribution of income inequality caused by the presence of search and matching frictions in the labor market. We study this problem in the context of a directed search model of the labor market populated by homogeneous workers and heterogeneous firms. The...

This paper studies the optimal redistribution of income inequality in a model with search and matching frictions in the labor market. We study this problem in the context of a directed search model of the labor market populated by homogeneous workers and heterogeneous firms. The optimal...

This paper studies the optimal redistribution of income inequality caused by the presence of search and matching frictions in the labor market. We study this problem in the context of a directed search model of the labor market populated by homogenous workers and heterogeneous firms. The optimal...

In this paper, we generalize the notion of Pareto-efficiency to make it applicable to environments with endogenous populations. Two efficiency concepts are proposed, P-efficiency and A-efficiency. The two concepts differ in how they treat people who are not born. We show how these concepts...

In this paper, we study optimal design of taxes and debt in the medium term in presence of domestic inequality and lack of commitment. We study an OLG economy in which individuals work and save for retirement when young. Government of the small open economy provides transfers to both the young...

This paper studies a Diamond–Dybvig model of providing insurance against unobservable liquidity shocks in the presence of unobservable trades. We show that competitive equilibria are inefficient. A social planner finds it beneficial to introduce a wedge between the interest rate implicit...

We develop a general method to study the effects of non-linear taxation in dynamic settings using variational arguments. We first derive general theoretical formulas that characterize the welfare effects of local tax reforms and, in particular, the optimal tax system, potentially restricted...

updated as a function of the labor income and the previous balance.

We analytically and quantitatively examine a prominent justifi…cation for capital income taxation: goods preferred by those with high ability ought to be taxed. We study an environment where commodity taxes are allowed to be nonlinear functions of income and consumption and …find that, when...

This paper derives novel formulas for the welfare gains of any tax reform around initial (optimal or suboptimal) dynamic tax systems. We use a perturbation-based method to express these formulas in terms of easily interpretable and empirically estimable parameters: elasticities of income and...
