Arturo Herrera: Tell us about some of the report's main findings.
What are the headline numbers on the global public sector workforce?
Zahid Hasnain: Thank you, Arturo. This report draws on more than a decade of data collection through the Bureaucracy Lab, a collaboration between the World Bank Group's Governance and Development Economics teams.
It brings together two main data sources. The first is the Worldwide Bureaucracy Indicators, which draw on labor force surveys covering more than 70 million individual observations across countries, providing data on public sector employment, wages, and workforce characteristics.
The second consists of surveys of public sector employees that examine the human resource management practices that drive productivity. We've conducted these surveys in 30 countries, adding two or three more each year, and they now include roughly 200,000 individual observations.
Together, these datasets provide an unprecedented picture of the global public workforce. One headline finding is that there are approximately 400 million public sector employees worldwide. Another is that, on average, the public sector offers a 20 percent wage premium compared with the private sector.
