Changing population age structures are shaping the trajectories of development in many countries, bringing opportunities and challenges. While aging has been a matter of concern for upper-middle and high-income economies, rapid population growth is set to continue in the poorest countries over...

Evidence indicates that trade costs are a much more substantial barrier to trade than tariffs are, especially in Sub-Saharan Africa. This paper decomposes trade costs into: (i) trade facilitation, (ii) non-tariff barriers, and (iii) the costs of business services. The paper assesses the poverty...

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...

This paper investigates the causal consequences of Tropical Storm Agatha (2010) -- the strongest tropical storm everto strike Guatemala since rainfall records have been kept -- on household welfare. The analysis reveals substantial negative effects, particularly among urban households. Per...

Climate change and climate policies will affect poverty reduction efforts through direct and immediate impacts on the poor and by affecting factors that condition poverty reduction, such as economic growth. This paper explores this relation between climate change and policies and poverty...

Empirical evidence indicates that in many developing regions, the extreme poor in more marginal land areas form a "residual" pool of rural labor. Structural transformation in such developing economies depends crucially on labor and land use decisions of these most-vulnerable populations located...

The transformation of India's unorganized sector is important to its modernization, growth, and attainment of regional economic equality. This paper documents several key facts about India's unorganized sector in manufacturing and services. First, the unorganized sector is large, accounting for...

Alternative scenarios are considered for reducing by one billion the number of people living below $1.25 a day. The low-case, "pessimistic," path to that goal would see the developing world outside China returning to its slower pace of growth and poverty reduction of the 1980s and 1990s, though...

The poor in Bangladesh are more likely to belong to households with a larger number of dependents and lower education among household members, be engaged in daily wage labor, own little land, and be less likely to receive remittances. This poverty profile for 2005 is similar to the profile in...

We are not seeing faster progress against poverty amongst the poorest developing countries. Yet this is implied by widely accepted "stylized facts" about the development process. The paper tries to explain what is missing from those stylized facts. Consistently with models of economic growth...
