The authors consider a transitory demographic shock that affects negatively the financing of retirement pensions-that is, workers either would have to pay more or retirees would receive less. In contrast to the existing literature, the authors endogenously determine optimal policies rather than...

In this paper we show that the generational accounting framework used in macroeconomics to measure tax incidence can, in some cases, yield inaccurate measurements of the tax burden across age cohorts. This result is very important for policy evaluation, because it shows that the selection of tax...

We develop a model for analyzing the sovereign debt crises of 2010 and 2011 in such European countries as Greece, Ireland, and Portugal. The government sets its expenditure-debt policy optimally given a fixed probability of a recovery in fiscal revenues. In doing so, the government can optimally...

The choice of the intertemporal discount rate affects the measurement of the tax burden of different age cohorts. Small changes in the discount rate affect not only the magnitude of the measured changes, but also the ranking of policies using that metric. The authors illustrate this problem in...

In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ permanently with respect to their ability to generate income. The welfare criterion we employ is...

This paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labor productivity risk gives rise to a nontrivial income and wealth distribution. A progressive tax system serves as a partial substitute...
