In the time between the publication of Smith’s book and the Great Depression, economists assumed that the study of individual markets would explain the behavior of variables like unemployment and output. The Great Depression puzzled economists, as they could offer no plausible explanation for the extreme market collapse of the 1930s. Smith believed that an invisible hand guides individuals to maximize their well-being and provide the best overall result to society as a whole. The concept essentially began with Adam Smith, a Scottish philosopher regarded as the father of economics, who authored The Wealth of Nations in 1776. In the 1800s, economics was simply the study of how human societies managed the production, distribution, and consumption of goods and services. Since its beginnings in the 1800s, the field of economics has expanded to try to address the complexity of today’s economies and systems. The Great Depression of the 1930s spurred the development of modern macroeconomic theory. Another key research area involves business cycles, an area of macroeconomics that considers variables like employment and national output. This can be modeled as a function of physical capital, human capital, labor force, and technology. One of macroeconomics’ key research areas involves economic growth, which refers to an increase in aggregate production in an economy. Finally, the principle of labor economics attempts to explain the relationship between wages, employment, and income. A third principle involves the costs of production, which ultimately determine the price of goods and services. Another principle involves production theory, which explores how goods and services are created or manufactured. One of the microeconomics’ core principles involves demand, supply, and equilibrium, as they collectively influence prices. Macroeconomics describes relationships among national income, savings, and overall price level. For instance, macroeconomics may analyze how the unemployment rate affects the gross domestic product. Macroeconomics tries to determine the optimal rate of inflation and factors that may stimulate economic growth. The term analyzes entire industries and economics rather than individuals or specific companies. Macroeconomics is the study of the decisions of countries and governments.
Microeconomics has applications in trade, industrial organization and market structure, labor economics, public finance, and welfare economics.
It doesn’t try to explain which actions should take place in a market, but rather the effects of changes in certain conditions. The term also considered taxes, regulations, and government legislation. Microeconomics is the study of individual and business decisions regarding the allocation of resources and prices of goods and services. Microeconomics and macroeconomics are two distinct categories of economics that complement each other.
