The limitations of decentralized world redistribution: An optimal taxation approach

A centralized scheme of world redistribution that maximizes a border-neutral social welfare function, subject to the disincentive effects it would create, generates a drastic reduction in world consumption inequality, dropping the Gini coefficient from 0.69 to 0.25. In contrast, an optimal decentralized (i.e., with no cross-country transfers) redistribution has a miniscule effect on world income inequality. Thus, the traditional public finance concern about the excess burden of redistribution cannot explain why there is so little world redistribution.Actual foreign aid is vastly lower than the transfers under the simulated world income tax, suggesting that voluntary world transfers - subject to a free-rider problem - produces an outcome that is consistent with rich countries such as the United States either placing a much lower value on the welfare of foreigners, or else expecting that a very significant fraction of cross-border transfers is wasted. The product of the welfare weight and one minus the share of transfers that are wasted constitutes the implicit weight that the United States assigns to foreigners. We calculate that value to be as low as 1/2000 of the value put on the welfare of an American, suggesting that U.S. policy is consistent with social preferences that place essentially no value on the welfare of the citizens of the poorest countries, or that implicitly assumes that essentially all transfers are wasted.     

GROWTH AND CONVERGENCE: A SOCIAL WELFARE FRAMEWORK

This paper proposes a social welfare framework in which to analyze the relationships between growth, trends in inequality, mobility, and social welfare. An application of the framework to worldwide and regional data on per capita GDP suggests a lack of convergence at the world level, opposite trends in convergence in various regions of the world, and a fairly low level of mobility or re-ranking between countries over time.     

Using the Capital Assets Pricing Model for risk management—A tool for multinational corporation managers

In this article, using a theoretical model and empirical analysis, we show how multinational corporations (MNCs) can utilize the fundamentals of the Capital Assets Pricing Model (CAPM) to formulate a strategic risk management in a global economy. We show that MNCs with branches all over the world, specifically those that specialize in nontradable goods (e.g., McDonald's), should consider each country's beta as the appropriate measure of the relevant risk attached to the location in the country. Finally, using data from the most recent world economic crisis (the subprime crisis), we show that during a world economic crisis the loss of growth will be significantly higher in countries with higher betas, and lower in those with lower betas. © 2011 Wiley Periodicals, Inc.
