Two Main Branches of Economics and their Utility

Economics is divided into two core facets: macroeconomics and microeconomics, each serving a distinct purpose.

Macroeconomics

This branch meticulously studies the behavior of an entire economy, encompassing markets and large-scale systems. In-depth examination of economy-wide phenomena, including inflation, price levels, economic growth rates, national income, GDP, and shifts in unemployment, form the crux of macroeconomics.

Microeconomics

Focused on individual entities, microeconomics delves into the decisions made by individuals and businesses. The allocation of resources for production, exchange, and consumption is a prime area of study. This branch also investigates prices and production within specific markets, as well as the interplay between different markets. While macroeconomics addresses aggregates, microeconomics hones in on singular market dynamics.

What is Economics?

Economics is the study of scarcity, resource utilization, and response to incentives, or the study of decision-making. It investigates how individuals, businesses, governments, and nations make resource allocation decisions. Economics focuses on human actions, with the assumption that humans act rationally, seeking the highest level of benefit or utility. Labor and trade studies are the foundations of economics. Because there are numerous applications for human labor and numerous methods for acquiring resources, it is the task of economics to determine which methods produce the best results.
