TL;DR: In this article, the authors studied the growth, welfare and efficiency consequences of the recent introduction of tax-favored retirement accounts in Germany in a general equilibrium overlapping generations model with idiosyncratic lifespan and labor income uncertainty, and showed that special provisions could be very effective in raising the participation of low-income households despite their low budgetary cost.

TL;DR: In this article, the authors simulate corporate tax reform in a single good, five-region (U.S., Europe, Japan, China, India) model, featuring skilled and unskilled labor, detailed region-specific demographics and fiscal policies.

TL;DR: In this paper, tax-favored retirement accounts are evaluated in a general-equilibrium overlapping-generations economy with idiosyncratic income risk and borrowing constraints, and it is shown that withdrawal penalties and tax-exempted accounts have positive growth and distributional implications.

TL;DR: In this paper, the authors examine the micro-and macroeconomic effects of generational policies using closed and open general equilibrium dynamic life-cycle models, and illustrate the broad array of demographic, economic, and policy issues that can be simultaneously incorporated within today's computable models of economic growth.
