Economics can be broadly
classified into fundamental economics, macro-economics, micro-economics,
international economics and personal finance economics. These are also
the core ideas that explain the various fields of economics and are
essential for understanding their purpose and application to real-world
situations. Each one of these categories has fundamental concepts that
can help understand economics in all its aspects.
Fundamental Economics
The
key concepts of fundamental economics include decision making and cost
benefit analysis, division of labor and specializations, economic
institutions, economic systems, incentives, money, opportunity cost,
productive resources, productivity, property rights, scarcity, trade
exchange and interdependence. Division of labor means dividing the
workforce into various crafts and professions. Productivity is the
relationship between inputs and outputs and this can be applied to
individual factors of production.
Macro-Economics
Macro-economics
deals principally with the national, regional or global economy at
large and these include aggregate demand and supply, budget deficits and
public debt, business cycles, economic growth, employment and
unemployment, fiscal policy, inflation and GDP. Demand and supply is the
twin driving forces of the market economy. Demand is not limited to
measuring the wants of people but also involves the amount of goods and
services that people are willing to buy. Fiscal policy comprises
government spending and taxation. It also involves any government
assistance to the private sector.
Micro-Economics
Micro-economics
focuses on the decisions and economic behavior of households and
businesses and how these affect the price and therefore, supply and
demand of goods and services. The fundamental concepts of
micro-economics include competition and market structures, consumers,
demand, elasticity of demand, income distribution, market and prices,
profits, price elasticity. Competition leads to efficiency among firms
and enables prices to be low. Competition can be categorized into
perfect and monopolistic competition. Price elasticity can be termed as a
measure of the response that demand has to a change in price.
International Economics
International
economics looks at how the financial dealings among different countries
affect consumers and governing financial institutions. Some basic
concepts here include balance of trade and balance of payments, economic
development, barriers to trade, exchange rates, benefits of trade and
foreign currency markets and trade. The exports of a country minus its
imports would be balance of trade. Balance of payments (BOP) is used by
counties to monitor all international monetary transactions. BOP is
divided into current account, capital account and financial account.
Personal Finance Economics
Personal
finance economics focuses on individuals and families and how they
handle their monetary resources. Key concepts include compound interest,
interest, financial markets, human capital, insurance, money
management, budgeting, risk and return, saving and investing. As per an
economist the meaning of saving would be consuming less in the present
and keeping your resources for future use. Investments are putting your
resources to work in order to earn more from them. This is just a brief
description of some of the fundamental concepts in economics.
