Relative Wealth, Consumption Taxation, and Economic Growth

Abstract

This paper examines the role of the relative wealth-induced status motive in affecting the neutrality of consumption taxation in an optimizing growth model. It is found that a key factor determining the validity of the neutrality of consumption taxation in both the level sense and the growth rate sense is the desire for relative wealth-induced social status. When individuals care about their relative wealth, a rise in consumption tax enhances the steady-state level of capital stock and consumption. Furthermore, if the production function takes a linear technology form as the engine of sustained growth, then increases in consumption taxation raise the economy's long-run growth rate. In addition, an optimal consumption tax policy provides full subsidies to consumption so as to induce the economy to achieve the social optimum and the optimal growth rate.
