March 2011The Possibilities For Global Poverty Reduction Using Revenues From Global Carbon Pricing
with Xiaojun Shi, John Whalley: w16878
Global carbon pricing can yield revenues which are large enough to create significant global pro-poor redistributive opportunities. We analyze alternative multidecade growth trajectories for major global economies with carbon tax rates designed to stabilize emissions in the presence of both continued country growth and autonomous energy use efficiency improvement. In our central case analysis, revenues from globally internalizing carbon pricing rise to 7% and then fall to 5% of gross world product. High growth in India and China is the major equalizing force globally over time, but the incremental redistributive effects that can be achieved using global carbon pricing revenues are large both in absolute and relative terms. Revenues from carbon pricing depend on growth and energy efficiency...

November 2009The Level and Distribution of Global Household Wealth
with Susanna Sandström, Anthony B. Shorrocks, Edward N. Wolff: w15508
We estimate the level and distribution of global household wealth. The levels of assets and debts for 39 countries are measured using household balance sheet and survey data centred on the year 2000. The determinants of mean financial assets, non-financial assets, and liabilities are studied empirically, and the results used to estimate average wealth holdings for countries lacking direct evidence. Data on the pattern of household distribution of wealth are assembled for 20 countries, which together account for 59 per cent of the global population and 75 per cent of global wealth. The observed relation between wealth and income distribution in these 20 countries allows estimates of wealth inequality to be produced for many other nations. Combining the figures for individual countries revea...

March 1989Taxes and Capital Formation: How Important is Human Capital?
with John Whalley: w2899
This paper explores how explicit incorporation of human capital affects dynamic general equilibrium analysis of the effects of taxes on capital formation and welfare in a life-cycle growth model. In contrast to the results of partial equilibrium analysis, we find that estimates of the full dynamic welfare costs of capital income taxes are little affected by incorporating human capital. While the short-run impact effects of replacing income taxes with wage or consumption taxes are significantly affected by endogenizing human capital, these effects are short-lived. In the long-run the rate of return on non-human capital falls to approximately its initial net of tax level, and steady-state human capital investment plans are therefore little affected by the tax changes. Although incorporating ...
