"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...

This paper uses a new database to establish two findings covering the first globalization boom before World War I, the second since World War II, and the autarkic interlude in between. First, there is strong evidence supporting a Tariff-Growth Paradox: protection was associated with fast growth...

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...

Debate over trends in the terms of trade between primary commodities and manufactures, their causes and their impact has dominated the literature for more than a century. Classical economists claimed that the terms of trade of primary commodities should improve since land and natural resources...

This paper documents the size and timing of the world inter-continental trade boom following the great voyages in the 1490s of Columbus, da Gama and their followers. Indeed, a trade boom followed over the subsequent three centuries. But what was its cause? The conventional wisdom in the world...

A Third World data base documenting commodity and factor prices 1870-1940 has been collected, yielding annual time series on wage/rental ratios, land/labor ratios, the terms of trade, and other explanatory variables for: Argentina, Burma, Egypt, Japan, Korea, the Punjab, Taiwan, Thailand and...

Some world historians attach globalization big bang' significance to 1492 (Christopher Colombus stumbles on the Americas in search of spices) and 1498 (Vasco da Gama makes an end run around Africa and snatches monopoly rents away from the Arab and Venetian spice traders). Such scholars are on...

There are two contrasting views of pre-19th century trade and globalization. First, there are the world history scholars like Andre Gunder Frank who attach globalization 'big bang' significance to the dates 1492 (Christopher Colombus stumbles on the Americas in search of spices) and 1498 (Vasco...

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...

This paper uses a new pre-1940 Third World data base documenting real wages and relative factor prices to explore their determinants. There are three possibilities: external price shocks, factor endowment changes, and technological change. As the paper's title suggests, technological change is...
