In the last decades, inequality of opportunity has been extensively studied by economists on the assumption that, in addition to being normatively undesirable, it can be related to low potential for growth. This paper evaluates inequality of opportunity and the different sources of unequal...

This paper provides new empirical insights on the joint distribution of consumption, income, and wealth in three of the poorest countries in the world ? Malawi, Tanzania, and Uganda ? all located in Sub-Saharan Africa (SSA). The first finding is that while income inequality is similar to that of...

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 proposes a methodology to approximate individual income distribution dynamics using only time series data on aggregate moments of the income distribution. Under the assumption that individual incomes follow a lognormal autoregressive process, this paper shows that the evolution over...

Expectations of future socioeconomic mobility are an important determinant of cur- rent policy preferences. But how may these expectations be formed? Using Life in Transition survey data for a large set of transition economies and several Western European countries, this paper examines the link...

The main goal of this paper is to document and analyze the long-term evolution of inequality of opportunity and thus extend the recent empirical literature, which is mainly concerned with its measurement at a specific point in time. Using repeated cross-section surveys for five European...

The adoption of the shared prosperity goal by the World Bank in 2013 and Sustainable Development Goal 10, on inequality, by the United Nations in 2015 should strengthen the focus of development interventions and cooperation on the income growth of the bottom 40 percent of the income distribution...
