Microeconomics Vs. Macroeconomics
Microeconomics and Macroeconomics are the two major branches of economics. Although these two branches of economics appear to be distinct, they are interdependent and complement one another because they deal with many of the same issues.
What is the Difference between Micro and Macro Economics?
The study of economics at the individual level is known as microeconomics. It is the study of specific markets and economic segments. It examines topics like consumer behaviour, individual labour markets, and firm theory. On the other hand, macroeconomics is the study of the entire economy. Aggregate variables such as aggregate demand, national output, and inflation are examined.
Microeconomics deals with issues such as:
- Individual market supply and demand
- Consumer choices, for example, are an example of individual consumer behaviour.
- Individual labour markets – for example, labour demand and wage determination
- Production and consumption-related externalities. e.g. Externalities: Positive or Negative
Macroeconomics deals with issues such as:
- Monetary and fiscal policy are two aspects of monetary and fiscal policy. What impact, for example, do interest rates have on the entire economy? Inflation and unemployment are caused by a variety of factors. Economic Development and the Production Cycle Globalization and international trade Differences in living standards and economic growth between countries are due to a variety of factors. Borrowing and investment by the government.
- Microeconomics is based on the idea that markets quickly reach equilibrium. The economy may be in a state of disequilibrium (boom or recession) for a longer period in macroeconomics. The fundamental principles of microeconomics are widely accepted. Macroeconomics, on the other hand, is a hot topic. Various schools of macroeconomics offer various explanations (e.g. Keynesian, Monetarist, Austrian, Real Business cycle etc).
- The most significant distinction between microeconomics and macroeconomics is one of scale. However, there are some distinctions.
What are the Similarities between Microeconomics and Macroeconomics?
Although it is convenient to divide economics into two branches – microeconomics and macroeconomics – this division is artificial to some extent.
In macroeconomics, microeconomic principles are applied. When studying the impact of devaluation, you are likely to apply the same economic principles, such as demand elasticity to price changes. Microeconomics has an impact on macroeconomics, and vice versa. A significant increase in oil prices will have a significant impact on cost-push inflation. Technology that lowers costs allows for faster economic growth. There is a blurring of lines. The housing market will experience a microeconomic effect if house prices rise. However, the housing market is so powerful that it could be classified as a macroeconomic variable that influences monetary policy. There have been attempts to predict the impact on the macroeconomy using computer models of household behaviour.
EQUILIBRIUM – DISEQUILIBRIUM
Markets, according to traditional economic analysis, return to equilibrium. When demand grows faster than supply, prices rise, and businesses respond by increasing supply. For a long time, macroeconomic analysis was assumed to behave similarly to microeconomic analysis. There wasn't a separate branch of economics called macroeconomics before the 1930s.
GREAT DEPRESSION AND THE BIRTH OF MACROECONOMICS
The economy in the 1930s was clearly out of balance. Unemployment was high, output was below capacity, and the economy was in a state of disarray. Classical economics lacked an explanation for this dis-equilibrium, which should not exist from a micro perspective.
J.M. Keynes published The General Theory of Employment, Interest, and Money in 1936. This looked into why the depression lasted so long. It looked into why we might be in a state of macroeconomic disequilibrium. For a long time, according to Keynes, we could have a negative output gap (macroeconomic disequilibrium). In other words, market microeconomic principles did not always apply to macroeconomics. Keynes wasn't the only economist who looked into this new field of study. Irving Fisher, for example, looked into the role of debt deflation in explaining the Great Depression. However, Keynes' theory was the most comprehensive and was instrumental in the development of a new branch of macroeconomics. Macroeconomics has existed as a distinct branch of economics since 1936. For issues like inflation, recessions, and economic growth, there have been competing explanations.
