October 2018Overcoming Wealth Inequality by Capital Taxes that Finance Public Investment
with Linus Mattauch, David Klenert, Joseph E. Stiglitz: w25126
Wealth inequality is rising in rich countries. Capital taxation used simply to finance redistribution may not be able to counteract this trend, but can increased public investment financed by higher capital taxes? We examine how such a policy affects the distribution of wealth in a setting with distinct wealth groups: dynastic savers and life-cycle savers. Our main finding is that public investment financed through capital taxes always decreases wealth inequality when the elasticity of substitution between capital and labor is moderately high. Indeed, for all elasticities of substitution greater than a threshold value, at high enough capital tax rates, dynastic savers disappear in the long run. Below these rates, both types of households co-exist in equilibrium with life-cycle savers gaini...
December 2012Risk Management and Climate Change
with Howard Kunreuther, Geoffrey Heal, Myles Allen, Christopher B. Field, Gary Yohe: w18607
The selection of climate policies should be an exercise in risk management reflecting the many relevant sources of uncertainty. Studies of climate change and its impacts rarely yield consensus on the distribution of exposure, vulnerability, or possible outcomes. Hence policy analysis cannot effectively evaluate alternatives using standard approaches such as expected utility theory and benefit-cost analysis. This Perspective highlights the value of robust decision-making tools designed for situations, such as evaluating climate policies, where generally agreed-upon probability distributions are not available and stakeholders differ in their degree of risk tolerance. This broader risk management approach enables one to examine a range of possible outcomes and the uncertainty surrounding the...
