Explanation:

Labour economics seeks to understand the functioning and dynamics of the markets for wage labour. Labour is a commodity that is supplied by labourers in exchange for a wage paid by demanding firms. Because these labourers exist as parts of a social, institutional, or political system, labour economics is often regarded as a sociology or political science.

Labour markets or job markets function through the interaction of workers and employers. Labour economics looks at the suppliers of labour services (workers) and the demanders of labour services (employers), and attempts to understand the resulting pattern of wages, employment, and income. These patterns exist because each individual in the market is presumed to make rational choices based on the information that they know regarding wage, desire to provide labour, and desire for leisure. Labour markets are normally geographically bounded, but the rise of the internet has brought about a 'planetary labour market' in some sectors.
