Macroeconomics approaches the study of economics from the viewpoint of
Macroeconomics can best be described as the
While complex macroeconomic systems have existed in human societies since ancient times, macroeconomics is a relatively new discipline. Until the 1930s, most economic research was mainly concerned with microeconomic phenomena, such as individual customers, businesses, and industries. The prevalent ideology was the classical school of economic thought, which derived its core concepts from Scottish economist Adam Smith’s theory of self-regulating markets. As a result, such economists concluded that macroeconomic events like rising unemployment and recessions were inevitable occurrences that could not be stopped. Market forces would ultimately correct such problems if left alone; therefore, any government interference in the operation of free markets would be unsuccessful at best and disruptive at worst.
In contrast to classical economists’ hands-off strategy, Keynesians argued that governments had a responsibility to tackle recessions. While the business cycle’s ups and downs cannot be entirely prevented, they can be managed with timely intervention. The economy is crippled during global downturns because there is virtually no market for something. When revenues fall, companies continue to lay off more employees, resulting in a further drop in income and demand, resulting in a prolonged recessionary period. Keynesians argued that because the government has leverage over tax revenues, it can create demand simply by increasing spending on goods and services during difficult times.
Macroeconomics is concerned with
By now, it should be obvious that economics encompasses a wide range of topics. Microeconomics is concerned with the behavior of individual actors in the economy, such as families, jobs, and companies, whereas macroeconomics is concerned with the economy as a whole. It focuses on broad issues like productivity, unemployment, inflation, and the trade deficit. Microeconomics and macroeconomics are complementary viewpoints on the overall topic of the economy, not different topics.
The basic truth that underlies the study of economics
Economists also consider two domains. Big-picture macroeconomics is concerned with how the economy as a whole functions. It researches topics like jobs, GDP, and inflation, which are often discussed in the news and in government policy debates. The interaction of supply and demand in individual markets for goods and services is the subject of microeconomics in the small picture.
The topic of macroeconomics is usually a country—how all markets combine to produce large phenomena that economists refer to as aggregate variables. The topic of research in microeconomics is a single market, such as whether price increases in the car or oil industries are motivated by supply or demand shifts. In macroeconomics, the government is a significant subject of research, such as the role it plays in contributing to overall economic growth or combating inflation. Since domestic markets are connected to foreign markets through trade, investment, and capital flows, macroeconomics often extends to the international sphere. Microeconomics, on the other hand, may have an international dimension. Single markets are frequently not limited to a single country; the global petroleum market is a good example.

Macroeconomics is a branch of economics that investigates how an entire economy—the market or other large-scale systems—behaves. Inflation, price levels, rate of economic growth, national income, gross domestic product (GDP), and increases in unemployment are all studied in macroeconomics.
Macroeconomics addresses a number of important issues, including: What causes unemployment? What is the source of inflation? What causes or promotes economic development? Macroeconomics tries to figure out how well an economy is doing, what factors are driving it, and how efficiency can be improved.
