In our daily lives, we face innumerable economic decisions, such as choosing what to buy with available money or what to do during our free time. These topics, which are related to the decisions of individual agents (individuals, families, businesses), are the object of study in an area of economics called microeconomics.


Another area of economics is macroeconomics, which studies the relationship between economic aggregates. Economic aggregates are elements that are made up of the sum of other variables. For instance, the Gross Domestic Product (GDP) is the sum of everything that is produced by each individual and organization within a country. The consumer price index is made up of the average price of numerous products. The aggregate investment is the sum of the expenditures in investment of all businesses and families of a country, etc.

Branches of Economics

Economics, in addition to the two perspectives already covered (macroeconomics and microeconomics), has many other branches, each one specializing in different objects of study. Thus, we have labor economics, which studies the labor market; public finances, which is dedicated to the study of the income and expenditures of the government; international economics, which studies the flow of resources between countries, etc.

The studies conducted by each of these sub-disciplines can take elements from both macroeconomics and microeconomics as well as from other social sciences such as history, psychology, etc., and from exact sciences such as logic and mathematics.
