Supply and demand is the core model of market economics. Demand shows how much consumers want at each price; supply shows how much producers will offer. Together they determine market prices and quantities.

Free trade removes barriers between countries, enabling specialization, lower prices, and economic growth. However, it also creates winners and losers — with potential costs for industries and workers in import-competing sectors.
Microeconomics studies the behavior of individual consumers and firms, while macroeconomics examines the economy as a whole. Both branches are essential for understanding how markets and economies function.
Unemployment is not a single phenomenon — economists distinguish several types, each with different causes and policy responses. The main types are cyclical, structural, frictional, and seasonal unemployment.
Fiscal policy refers to government decisions about spending and taxation to influence economic conditions. Expansionary fiscal policy stimulates growth; contractionary fiscal policy cools an overheating economy.
Monetary policy involves central bank decisions about interest rates and money supply to manage inflation, employment, and economic stability. It is the primary macroeconomic tool used to maintain price stability.
An economic system is the way a society organizes production, distribution, and consumption of goods and services. The four main types are market, command, mixed, and traditional economies, each with distinct characteristics.
Inflation is the sustained increase in the general price level of goods and services over time, reducing the purchasing power of money. Understanding inflation is fundamental to macroeconomics and economic policy.
Inflation can be caused by excess demand (demand-pull), rising production costs (cost-push), or a self-reinforcing wage-price spiral (built-in inflation). Each cause requires different policy responses.
Gross Domestic Product (GDP) is the total monetary value of all goods and services produced within a country in a given period. It is the most widely used measure of an economy's size and performance.
Trade barriers are government-imposed restrictions on the free flow of international trade — including tariffs (import taxes), quotas (volume limits), embargoes (total bans), subsidies, and non-tariff barriers such as regulatory standards — used to protect domestic industries or achieve policy objectives.
Absolute advantage means producing a good using fewer resources than a trading partner. Comparative advantage means producing a good at a lower opportunity cost — and it is this concept, not absolute advantage, that explains why mutually beneficial trade occurs even when one country is more efficient at producing everything.
The balance of trade is the difference between the value of a country's exports and the value of its imports over a given period. A trade surplus occurs when a country exports more than it imports; a trade deficit when it imports more than it exports. It is the largest component of the balance of payments and a key indicator of a country's international economic position.
Comparative advantage is the economic principle that a country (or individual) should specialize in producing goods where its opportunity cost is lowest relative to trading partners, and trade for everything else. Even if one country is more efficient at producing everything, both countries benefit from specialization and exchange — a counterintuitive but powerful insight that underpins the case for international trade.
Comparative advantage explains why countries trade even when one nation can produce all goods more efficiently.
