    This module provides an introduction to the relationship between economics and social policy and the way in which economic ideas, approaches and analysis can contribute to policy development. A brief history of economic thought provides a backdrop to the development of welfare economics and debate about the involvement of the state and the market in social welfare and wellbeing. The structure and operation of public expenditure management in the UK is explored, along with an examination of how money is spent across different sectors, services and social groups. Examples of theory, policy and practice are drawn from health economics and other fields.
