Answer:
When setting up a business
Step-by-step explanation:
For any business, having as much knowledge as possible about how the economy of the place where the business is based will evolve is essential to decide where to direct its future plans. In addition, the Macroeconomy also tries to anticipate where the international environment is evolving, which is of great importance for all types of businesses, and even more so when SMEs are increasingly involved in the challenge of exporting and have more and more international competition.
Macroeconomics is the branch of Economic Theory that studies the behavior of aggregate variables in a given place, understanding all economic agents as a whole.
Many other branches of Economics study how the decisions of some individuals affect others. For example, the demand decisions of a group of individuals for a good can be studied in order to study later what the demand of the group of consumers would be, by adding up all the demands of the individuals.
This is not the case with macroeconomics. It does not attempt to add up the individual decisions that affect a good, a labor market, or a specific decision where a group of people interact, but studies the economy of a place as a whole. It studies the consumption of all the goods in the economy, the realization of the set of investments, the behavior of its labor markets, etc.
