National saving rates differ enormously across developed countries. But these differences obscure a common trend, namely a dramatic decline over time. France and Italy, for example, saved over 17 percent of national income in 1970, but less than 7 percent in 2006. Japan saved 30 percent in 1970,...

Recent evaluations of traditional microfinance loans have found no significant impacts on borrower incomes or productive activities. We examine whether this can be remedied by (a) modifying loan features to facilitate financing of working capital needs of farmers, and (b) delegating selection of...

This paper questions the widely accepted view that deficits have real effects in the life cycle model. Standard analyses of deficits within life cycle models treat the government as a dictatorial entity that can effect any intergenerational redistribution it desires. In contrast, this paper...

The precautionary motive for saving is an important issue that is receiving increasing attention. Part of the motivation for this interest stems from the post war coincidence of two trends, one a decline in the U.S. rate of saving and the other an increase in insurance of various types,...

This paper discusses recent neoclassical analyses of taxation and savings.Contrary to the popular view that fiscal policy has highly ambiguous impacts on savings, neoclassical models admit a host of policies with clear and potentially quite powerful affects on the accumulation of wealth.The...

This paper discusses conceptual problems of distinguishing "expenditure" policy from "tax" policy and "deficit" policy. The paper argues that each of these concepts is ill-defined and does not provide a useful basis for examining the government" underlying fiscal policies. The fundamentals of...

Generational policy is a fundamental aspect of a nation's fiscal affairs. The policy involves redistributing resources across generations and allocating to particular generations the burden of paying the government's bills. This chapter of the second edition of The Handbook of Public Economics...

Almost two decades have passed since the development of the prototype of the Auerbach-Kotlikoff dynamic life-cycle simulation model. The model has been used to examine a host of policies, including tax reform, tax cuts, investment incentives, tax progressivity, expansion of social security,...

This paper studies the macroeconomic and efficiency effects of privatizing social security. It does so by simulating alternative privatization schemes using the Auerbach-Kotlikoff Dynamic Life-Cycle Model. The simulations indicate three things. First, privatizing social security can generate...

This paper uses the Auerbach-Kotlikoff Dynamic Life-Cycle Model (AK Model) to examine the macroeconomic and efficiency effects of privatizing social security, and a simple privatization proposal, the Personal Security System, to discuss other issues associated with privatization. According to...
