What is the difference between macro and micro economics?

Macroeconomics is the study of the performance, behavior, systems, and the decision-making process in a given economy wholly. This study aims to provide a national growth in the economy and maximize the national income. It has most of its topics looking into full employment, equal income distribution, equitable wealth distribution, external balance, and enhancing productivity. Macroeconomics' models need to address the effects of short-term changes in the national income and the determinants of long-term economic growth.

On the other hand, microeconomics entails the economic interactions of a specific individual or a single company. It studies markets, and its primary goal is to study the market and develop product prices that best distribute limited resources among different users. The study covers topics in labor economics, industrial organization, health, law, and urban economics. It assumes that business is rational and that they produce goods that maximize their gains.
