This paper documents stylized facts on the process of structural transformation around the world and empirically analyzes its determinants using data on real value added by sector of economic activity (agriculture, manufacturing and services) for a panel of 168 countries over the period 1970-2010. The analysis points to large differences in sector shares both across and within regions as well as for countries at similar levels of economic development. Using both linear and quantile regression methods, it finds that a large proportion of the crosscountry variation in sector shares can be accounted for by country characteristics, such as real GDP per capita, demographic structure, and population size. It also finds that policy and insitutional variables, such as product market reforms, openness to trade, human and physical capital, and finance improve the baseline model's ability to account for the variation in sectoral shares across countries.

Estimates of the current and future structure of employment in sub-Saharan Africa (2005-20) are obtained based on household survey estimates for 28 countries and an elasticity-type model that relates employment to economic growth and demographic outcomes. Agriculture still employs the majority of the labor force although workers are shifting slowly out of the sector. Sub-Saharan Africa's projected rapid labor force growth, combined with a low baseline level of private sector wage employment, means that even if sub-Saharan Africa realizes another decade of strong growth, the share of labor force employed in private firms is not expected to rise substantially. Governments need to undertake measures to attract private enterprises that provide wage employment, but they also need to focus on improving productivity in the traditional and informal sectors as these will continue to absorb the majority of the labor force.
