Measuring Government Activity The size and the economic significance of the public sector make it a major contributor to economic growth and social welfare. The goods and services government provides its redistributive and regulatory powers and how those are exercised affect the way business is conducted and people live their lives in every country. Citizens are entitled to understand how government works and how public revenues are used. This book provides a significant contribution to developing a coherent reliable system for data collection and analysis. It summarises the available OECD and other international data on public sector inputs and processes. It also examines the existing internationally comparable data on outputs and outcomes and recommends new approaches to measurement.
