"Is inequality largely the result of the Industrial Revolution? Or, were pre-industrial incomes and life expectancies as unequal as they are today? For want of sufficient data, these questions have not yet been answered. This paper infers inequality for 14 ancient, pre-industrial societies using...

Klaus Deininger and Lyn Squire have recently produced an inequality data base for a panel of countries from the 1960s to the 1990s. We use these data to decompose the sources of inequality into three central parts: the demographic or cohort size effect; the so-called Kuznets Curve or demand...

The world has seen two globalization booms over the past two centuries, and one bust. The first global century ended with World War I and the second started at the end of World War II, while the years in between were ones of anti-global backlash. This lecture reports what we know about the...

The world economy has become more unequal over the last two centuries. Since within- country inequality exhibits no ubiquitous trend, it follows that virtually all of the observed rise in world income inequality has been driven by widening gaps between nations, while almost none of it has driven...

If we have learned anything from the recent outpouring of empirical growth equations is that life is far too complex to expect unconditional' convergence among all countries and at" all times. This fact motivates two questions. First, why has it taken economists so long to learn" the same lesson...

The late 19th and the late 20th century shared more than simply globalization and convergence. Globalization also seems to have had the same impact on income distribution: in the late 19th century, inequality rose in rich countries and fell in poor countries; according to Adrian Wood, the same...
