Unit 1 concerns competitive markets: how they work, and why they fail. This unit examines the market mechanism in the context of various markets. It also analyses the causes of market failure and possible policy remedies. For example, policies for dealing with pollution or monopoly abuse.
Unit 2 considers the measures of macroeconomic performance and instruments of economic policy. The unit deals with issues such as inflation, unemployment, economic growth, and international trade. It also deals with the role of government in managing the economy.
