For example, increased inflation (macro effect) would cause the price of raw materials to increase for companies and in turn affect the end product's price charged to the public. Microeconomics takes what is referred to as a bottoms-up approach to analyzing the economy while macroeconomics takes a top-down approach.

Macro Economics means study of economy as whole
Inflation is calculated for the whole country. So the study of inflation is covers under "MACRO ECONOMICS"

Macroeconomics

The study of inflation falls under the field of macroeconomics. Macroeconomics is concerned with the overall behavior and performance of an economy as a whole, including the study of key economic indicators such as inflation, unemployment, GDP growth, and monetary policy.

Definition of Inflation

Inflation refers to the sustained increase in the general price level of goods and services in an economy over a period of time. It is typically measured by the consumer price index (CPI) or the producer price index (PPI). Inflation can erode the purchasing power of money, disrupt economic stability, and impact various aspects of an economy, such as wages, investments, and consumer behavior.

Study of Inflation in Macroeconomics

Macroeconomics focuses on understanding and analyzing the behavior and performance of the entire economy. It examines the factors that contribute to inflation, its impact on different sectors and groups within the economy, and the policy measures that can be taken to control or manage inflation.

Key Areas of Study

Within the study of inflation, macroeconomics covers several key areas:

1. Causes of Inflation: Macroeconomists analyze the various factors that contribute to inflation, such as changes in money supply, aggregate demand, production costs, and expectations. They examine the relationship between these factors and the overall price level in the economy.

2. Types of Inflation: Macroeconomics distinguishes between different types of inflation, such as demand-pull inflation, cost-push inflation, and built-in inflation. It explores the causes and consequences of each type and their implications for economic stability.

3. Effects of Inflation: Macroeconomists study the impact of inflation on different economic variables, such as wages, interest rates, investment, consumption, and savings. They analyze how inflation affects the distribution of income and wealth in society and its implications for social welfare.

4. Inflation Measurement: Macroeconomics develops methodologies and tools for measuring and tracking inflation. This includes the calculation of price indices, inflation rates, and inflation expectations. It also examines the accuracy and reliability of inflation data.

5. Inflation Policy: Macroeconomists evaluate the effectiveness of different policy measures to control or manage inflation. This includes monetary policy tools, such as interest rate adjustments, open market operations, and reserve requirements, as well as fiscal policy measures, such as taxation and government spending.

Conclusion

In summary, the study of inflation is an integral part of macroeconomics. Macroeconomists analyze the causes, effects, measurement, and policy implications of inflation in order to understand its impact on the overall economy and develop strategies for maintaining stable and sustainable economic growth.
