Singapore is often recognised to be one of the most successful economies in the world in terms of its remarkable pace of economic and social transformation. Its success is the result of a judicious blend of markets and government, high quality of governance and the use of public policies that have been coherent, consistent and coordinated.This book showcases the contribution of economics to Singapore's public policymaking. To illustrate the diverse areas that economic analysis has contributed to, this book comprises three sections that span the economic and non-economic policy domains in Singapore. Section I covers economic policies relating to economic growth, trade, investments, productivity, innovation, industrial development, the enterprise landscape and manpower. Section II highlights socioeconomic and security policies, and covers themes such as income inequality and mobility, families, healthcare costs and crime. In Section III, the focus is on infrastructural policies relating to the environment, housing and land transport.This book commemorates the 20th anniversary of the Singapore Government's Economist Service (ES). As the premier service for economists in the Singapore public sector, the ES plays an integral role in supporting evidence-based policymaking through rigorous economic research and analysis of public policies.
