At its Spring Meeting, the Development Committee endorsed the eradication of poverty and the promotion of shared prosperity as the twin goals of the World Bank Group mission. What development agenda is implied by these goals? What are the key elements of a development policy framework that should inform WBG strategy to achieve these goals?
Economic growth has been central to the progress achieved in reducing poverty and boosting the incomes of the bottom segments of the population. The change in poverty can be decomposed into the growth of average incomes and the change in inequality. Cross-country analysis shows that, in the medium- to long-term, upwards of 70 percent of the variation in poverty can be attributed to economic growth. Similarly, the rise in the incomes of the bottom 40 percent of the population can be decomposed into the change in the income per capita of the country and the change in the share of total income that is received by the bottom 40 percent. A review of the data for changes in the income per capita of the bottom 40 percent over the past two decades reveals that, in most cases, overall economic growth played the predominant role.
