Economics seeks to understand the functioning of the marketplace and its relevance for firms.

Microeconomics examines consumers, firms and workers within markets, seeking to understand

- why prices change for particular products,

- what influences the costs of firms, and

- what will influence the firm's level of productivity.

Macroeconomics is the examination of the economy as a whole, and, therefore, considers issues such as

- the level of economic activity and growth,

- the level of prices and inflation,

- employment and unemployment, and

- international trade and FDI, Balance of Payment, and exchange rates.
