Microeconomics practices

Microeconomics is the branch of Economics that analyzes firms, individuals and households’ decision-making processes, behaviors and interactions that affect the allocation of limited resources of the society. In short, it examines the behavior of individual economic units.

In particular, Microeconomics focuses on patterns of supply and demand and the determination of price and output in individual markets. It concerns itself with individual economic activity and decision-making process that eventually determines the relative prices and the distribution of the economy’s output.

With the assumption of rational self-interest, the dynamics of Microeconomics lies in the individual and group choices of the society. Choices typically requires time, effort and information, which are all scarce and valuable.
