<p><b>New page</b></p><div>'''Comparative advantage''' is the principle that a country, individual, or firm should specialise in producing the goods and services for which it has the lowest [[opportunity cost]] relative to others, even if it is not the most efficient producer in absolute terms. The theory, first articulated by [[David Ricardo]] in 1817, is one of the most important and counterintuitive results in [[economics]].<ref name="wiki">Wikipedia contributors, "Comparative advantage".</ref><br />

== The principle ==<br />
<br />
The theory of comparative advantage holds that gains from trade arise from differences in the relative costs of production. A country should specialise in goods it produces at a relatively lower opportunity cost and trade for goods it produces at a relatively higher opportunity cost. Because both parties can then consume beyond their own production possibilities, trade is mutually beneficial even when one country is more efficient at producing everything.<ref name="wiki"/><br />

| [[Absolute Advantage]]<br />
| A country can produce a good using fewer resources than another.<br />

| '''Comparative advantage'''<br />
| A country can produce a good at a lower relative (opportunity) cost than another.<br />

<br />
The crucial insight is that trade is driven by comparative advantage, not absolute advantage. A country may have an absolute advantage in all goods yet still benefit from specialising and trading.<ref name="wiki"/><br />
<br />
== Illustration ==<br />
<br />
A classic illustration involves two countries and two goods. Suppose Country A can produce either 10 units of cloth or 5 units of wine with a given set of resources, while Country B can produce either 6 units of cloth or 4 units of wine. Country A has an absolute advantage in cloth and Country B in neither good absolutely, but each has a comparative advantage in one good. By specialising according to comparative advantage and trading, both countries can consume more than they could in isolation.<ref name="wiki"/><br />
<br />
== Significance and limitations ==<br />
<br />
Comparative advantage provides the theoretical foundation for [[free trade]] and for the case against [[trade protectionism]]. However, the theory has limitations: it is a static analysis that ignores adjustment costs, distributional effects, and the possibility of [[market failure]], and it assumes full employment and mobile factors of production within a country. Modern trade theory has extended the concept to account for [[economies of scale]], imperfect competition, and global value chains.<ref name="wiki"/><br />
