Economics is known as common science as it analyzes manufacturing, allocation, and expenditure of merchandise and services. The term ‘Economics’ is derived from an Ancient Greek word, “Oikonomia” which means “management of household and administration, hence, “system of the house”.
However, the contemporary financial models under study have its origin in the financial system of the late 19th century. An empirical approach (as in the case of bodily sciences) was considered essential for the growth and development of contemporary economics.
The sole purpose of Economics is to explain how an economy works and how financial agents correspond and interchange matters. Other than the corporate sector which mainly covers commerce, finance and administration, economic policies are implemented in the fields concerning the civil sector such as teaching, law, government, discipline, religion, communal institutions and war. At the turn of the 21st century, the social sciences were repeatedly influenced by finance, a concept we know as Financial Imperialism.
Economics primarily can be categorized into two as per the size of an economy. The textbook distinction between the two is that Microeconomics examines the performance of essential factors in the financial sector such as entity markets. Macroeconomics, on the other hand, focuses on issues actuating the entire financial sector, including factors like unemployment, price hikes, fiscal growth and policies.
Microeconomics as the name suggest, means “small economics”. This branch of economics is concerned with issues at the individual level. It studies how different entities such as firms, households and individuals working for them interact in the market where goods and services are produced. It mainly concerns with how the production of these goods and services affect the prices and how there is a consequent change in demand and supply. This branch of economics upholds the inter-relation between households and firms as the irreducible factor in the finance sector given certain prerequisites such as scarcity and government rule. There are certain assumptions in this branch. Supply and Demand theory assumes that markets are perfectly competitive and buyers and sellers cannot influence prices. However, this isn’t true. Prices do get influenced due to individual buyers and sellers. Microeconomics aims for balance in the marketplace. For instance, a market might be for manufactured goods, say, fresh callus, or the services of an issue of production, say bricklaying. The theory tries to strike a balance between the price in aggregate demanded by a buyer and price per unit supplied by a seller. It combines these two factors to define how the marketplace may reach a consensus or react to changes in marketplace due to excess of time.
Macroeconomics examines the financial system as a whole to give details of broad aggregates and their connections “top down”, i.e., by means of a cut down form of general-equilibrium theory. Such aggregates include National income and output, Unemployment rate, and Price inflation. They also include sub aggregates such as total expenditure, asset expenses and their mechanism. It also studies effects of financial and fiscal policies.
International economics studies determinants of goods and services flow crossways international limits. It also concerns the dimension and sharing of gains on or after trade. Policy application estimates the belongings of altering tariff rates and deal quotas. International money is a macroeconomic field which looks at the flow of assets across global borders, and the belongings of these actions on exchange tax. Increased trade in merchandise, services and assets among countries is the main effect of modern globalization.
