The results of new direct price level comparisons across 146 countries in 2005 have led to large revisions of PPP (purchasing power parity) exchanges rates, particularly for China and India. The recalculation of international and global inequalities, using the new PPPs, shows that inequalities...

The authors develop and implement a method for measuring the frequency of changes in power among distinct leaders and ideologically distinct parties that is comparable across political systems. The authors find that more frequent alternation in power is associated with the emergence of better...

The paper presents a nontechnical summary of the current state of debate on the measurement and implications of global inequality (inequality between citizens of the world). It discusses the relationship between globalization and global inequality. And it shows why global inequality matters and...

The effect of the distribution of political rights on income inequality has been studied both theoretically and empirically. This paper reviews the existing literature and, in particular, the available empirical evidence. Our reading of the literature suggests that formal exclusion from the...

We would expect that the process of globalization between 1870 and 1914 and subsequent disintegration of the world economy during the interwar period would have led first to income convergence and then to income divergence between the participating countries. But in fact we find stronger...

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...

Suppose that all people in the world are allocated only two characteristics: country where they live and social class within that country. Assume further that there is no migration. We show that 90 percent of variability in people’s global income position (percentile in world income...

Using for the first time survey data from 26 post-Communist countries, covering the period 1990-2005, the paper examines correlates of unprecedented increases in inequality registered by most of these economies. We find that, after controlling for country-fixed effects and type of survey used,...

Eastern Europe experienced an economic crisis between 1978 and 1987. Declining income led to substantial increases in poverty rates in Poland and Yugoslavia, while poverty in Hungary remained at about the same level as before the crisis. In all three countries urban poverty increased, as the...

Many economists dismiss the relevance of inequality (if everybody's income goes up, who cares if inequality is up too?), and argue that only poverty alleviation should matter. This note shows that we all do care about inequality, and to hold that we should be concerned with poverty solely and...
