Many low-income countries, such as Haiti, have high ambitions and socioeconomic needs to achieve substantial income growth, especially for the poorest income quintiles. This situation raises the question of policy prioritization, which is often difficult to address, since reliable...

This paper revisits four recent cross-country empirical studies on the effects of inequality on growth. All four studies report strongly significant negative effects, using the popular system generalized method of moments estimator that is frequently used in cross-country growth empirics. This...

The impacts of climate change on poverty depend on the magnitude of climate change, but also on demographic and socioeconomic trends. An analysis of hundreds of baseline scenarios for future economic development in the absence of climate change in 92 countries shows that the drivers of poverty...

One of the two goals of the World Bank Group's new strategy is to promote shared prosperity, defined as the income growth of the bottom 40 percent of the population. The simple monitoring indicator then is the income per capita of the bottom 40 percent of the population. The growth of this...

Among the conclusions the authors reach about malnutrition rates, among different economic groups: 1) inequalities in malnutrition almost disfavor the poor; 2) it's not just that the poor have higher rates of malnutrition. The rate of malnutrition declines continuously with rising living...

"Shared prosperity" has become a common phrase in the development policy discourse. This short paper provides its most widely used operational definition -- the growth rate in the average income of the poorest 40 percent of a country's population -- and describes its origins. The paper discusses...

In the standard model of corruption, the rich are more likely to pay bribes for their children's education, reflecting higher ability to pay. This prediction is, however, driven by the assumption that the probability of punishment for bribe-taking is invariant across households. In many...

The paper argues that there is a greater commonality of approach between the National Innovation Systems approach and mainstream economic analysis than is often asserted, and that a better dialogue between the two could strengthen both perspectives. To this end, the paper uses an off-the-shelf...

"Informality" is a term used to describe the collection of firms, workers, and activities that operate outside the legal and regulatory systems. It is widespread in the majority of developing countries--in a typical developing economy, the informal sector produces about 35 percent of gross...

Major resource discoveries have transformed growth prospects for many low-income countries. However, the sharp downturn in commodity prices in recent years is affecting resource investment in these countries, and may delay the development of recent discoveries into production. This study...
