This paper explores the propositions that, income inequality is relatively stable within countries; and that it varies significantly among countries. A new and expanded data set provides broad support for both propositions. Drawing on a political economy and capital market imperfection arguments...

This paper extends an otherwise standard one-sector neoclassical growth model by postulating that the depreciation rate of physical capital depends on the agent's efforts on maintenance and repairs. Specifically, we introduce endogenous depreciation into the standard optimal growth model via two...

While this paper emphasizes the analytical ambiguity of the relationship between savings and income inequality, the empirical examination renders weak support for a negative association between them. However, this relationship is not very robust. Subsamples of OECD countries and Asian countries...

In a recent paper [Luo, Smith, and Zou (2009)] we showed that the spirit of capitalism could in theory resolve the two fundamental anomalies of modern consumption theory, excess sensitivity and excess smoothness. However, that basic model could not plausibly explain the empirical magnitude of...

The optimal inflation tax is reexamined in the framework of dynamic second best economy populated by individuals with inflation aversion. A simple formula for the optimal inflation rate is derived. Different from the literature, it is shown that if the marginal excess burden of other distorting...

This paper surveys the literature and assesses the magnitude, persistence, and depth of poverty and inequality in Sub-Saharan Africa using empirical analysis. Our analysis explores linkages between three key facts about development in Sub-Saharan Africa: poor economic growth, poor performance in...

This paper aims to enhance the understanding of provincial tax performance in China, paying special attention to the recent fiscal reforms in the 1980s and in 1994. Using provincial panel data for the period 1986-2004, our analysis consists of two steps. First, a combined fixed time effects and...

The authors develop a simple analytical framework that shows how the composition of public spending affects economic growth. Distinguishing between productive and unproductive government spending (that which complements private sector productivity and that which does not), they show that...
