Introduction to
Economics
Economics is the study of how individuals, businesses, and societies make
decisions about the use of scarce resources to meet their needs and wants.
It helps us understand the complex web of interactions that drive our
financial and material well-being.

3 Macro and Micro Perspectives
Economics encompasses both the big picture (macroeconomics)
and the individual choices (microeconomics) that drive the broader
economic system.
Brief History of Economics
1 Opportunity Cost
Opportunity cost is the value of the next best alternative
that you give up when making a choice. In other words, it
represents the benefits you could have gained by choosing
a different option. It's the cost of the foregone opportunity.
2 Supply and Demand
Supply and demand is a basic economic model that explains
how prices are determined in a market. Supply refers to how
much of a product or service is available, while demand
refers to how much people want it. Prices tend to rise when
demand exceeds supply and fall when supply exceeds
demand. The point where supply equals demand is called
the equilibrium price.
3 Modern Economics
The 20th century saw the rise of Keynesian economics,
neoclassical synthesis, and the development of more
sophisticated mathematical and empirical methods.
4 Scarcity
Scarcity refers to the fundamental economic concept
where resources (such as goods, services, time, or
materials) are limited in availability, while human wants and
needs are potentially infinite. This creates a situation where
choices must be made on how to allocate these limited
resources efficiently. In simple terms, scarcity means there
is not enough of something to satisfy everyone's desires.

societies.
Market
Market economics, or a market economy, is an economic system
where decisions about production, distribution, and prices are
determined by the interactions of individuals and businesses in a free
market. Supply and demand drive the economy, and prices are set
based on competition without significant government intervention.
The United States and many other capitalist countries operate under
market economies.

Overview of Trade Theories
1 Comparative Advantage
The idea that countries should specialize in producing
goods and services where they have the lowest opportunity
cost, leading to mutually beneficial trade.
2 Tariffs and Trade Barriers
Governments may impose tariffs or other trade restrictions
to protect domestic industries, but these can also lead to
inefficiencies and higher consumer prices.
3 Free Trade Agreements
International trade agreements that aim to reduce or
eliminate tariffs and other barriers to the free flow of goods,
services, and capital across borders.
Current Economic Issues
Facing the Global Economy
Income Inequality
Current economic issues in income inequality refer to the growing gap
between the rich and the poor, where wealth and income are increasingly
concentrated in the hands of a small portion of the population. This
disparity can lead to reduced social mobility, decreased economic growth,
and greater social tension. Factors contributing to income inequality
include technological advancements, globalization, wage stagnation, and
tax policies that may favor the wealthy. Addressing these issues often
involves debates around policies like progressive taxation, minimum wage
increases, and access to education and healthcare.
Persistent Unemployment
Elevated levels of joblessness, often disproportionately affecting certain
demographic groups or regions.
Climate Change Impacts
The economic costs and disruptions associated with the effects of global
warming, such as natural disasters and shifts in agricultural productivity.
