Abstract:
I review the literature on the effects of inequality on growth and development in the developing world. Two stylized facts emerge from empirical studies: inequality is more likely to harm growth in countries at low levels of income (below about $3200 per capita in 2000 dollars); and it is at high levels of inequality (at or above a Gini coefficient of .45) that a negative association emerges. Between 15 and 40 percent of the developing world's population lives in countries with these characteristics, depending on the inclusion of China, whose level of inequality has recently been measured at almost .45. Theory and evidence suggest that high inequality affects growth: (1) through interaction with incomplete and underdeveloped markets for capital and information; (2) by discouraging the evolution of the economic and political institutions associated with accountable government (which in turn enable a market environment conducive to investment and growth); and (3) by undermining the civic and social life that sustains effective collective decision-making.

12. Stormy Days on an Open Field: Asymmetries in the Global Economy

Abstract:
Openness is not necessarily good for the poor. Reducing trade protection has not brought growth to today's poorest countries, and open capital markets have not been good for the poorest households in emerging market economies. In this paper I present evidence on these two points. First, countries highly dependent on primary exports two decades ago, despite their substantial engagement in trade and a marked decline in their tariff rates in the 1990s, have failed to grow. Second, within high-debt emerging market economies the financial crises of the last decade, whether induced by domestic policy problems or global contagion, have been especially costly for the poor (in welfare terms if not in terms of absolute income losses). I discuss the asymmetries in the global economy that help explain why countries and people cannot always compete on equal terms on the “level playing field” of the global economy.
