Topic Four (1.4): Private Costs and Benefits, Externalities and Social Costs and Benefits

Introduction

In this topic, you will learn how to define negative and positive externalities and how these apply to private costs and benefits, external costs and benefits, and social costs and benefits. You will analyse deadweight losses arising from externalities and will learn how to explain terms such as ‘asymmetric information’ and ‘moral hazard’. Finally, you will be able to evaluate the use of costs and benefits in analysing decisions.
