Trade, Specialization, and Opportunity Cost

Vocabulary flashcards covering core concepts of trade, specialization, division of knowledge, absolute and comparative advantage, and opportunity cost calculations from the lecture notes.

Division of Knowledge

An economic concept demonstrating that total society-wide knowledge expands when individuals specialize in specific domains rather than each person possessing the exact same limited set of skills.

Cloneia Total Known Facts

$1 \times 10^6$ total distinct facts, calculated because all $1 \times 10^6$ inhabitants know the exact same list of $1 \times 10^6$ facts.

Differentia Total Known Facts

$1 \times 10^{12}$ total distinct facts, calculated because each of its $1 \times 10^6$ inhabitants knows a completely different set of $1 \times 10^6$ facts.

Adam Smith's Sauntering Observation

The principle from The Wealth of Nations stating that switching between different tasks wastes time and reduces productivity because a person saunters a little when turning from one employment to another.

Opportunity Cost (Nikkita's Transmission Repair)

$2$ fuel injectors, which is the alternative output sacrificed per hour when repairing $1$ transmission.

Opportunity Cost (Ruby's Email Responses)

$200$ telephone calls per hour, which is the alternative customer service work foregone when responding to $400$ emails per hour.

Opportunity Cost (Deirdre's Half-Book)

$2.5$ articles, based on the trade-off rate where writing $1$ full book is equivalent to writing $5$ articles in a year.

American vs. Chinese Worker Wage Gap

The pay disparity primarily explained by American workers typically being more productive than Chinese workers.

Julia Child Productivity Factor

High compensation resulting from high overall productivity through media reach, such as reintroducing French cooking to millions of Americans in the 1960s beyond standard kitchen production.

North (International Economics)

A shorthand term referring to the high-tech developed countries of East Asia, North America, and Western Europe.

South (International Economics)

A shorthand term referring to the rest of the world outside the high-tech developed regions.

Absolute Advantage (High-Quality Cars)

Held by the North, requiring only $30\,hours$ to produce one high-quality car compared to $60\,hours$ in the South.

Absolute Advantage (Low-Quality Cars)

Held by the North, requiring only $20\,hours$ to produce one low-quality car compared to $30\,hours$ in the South.

North's Opportunity Cost for High-Quality Cars

$1.5$ low-quality cars, calculated from the ratio of $30\,hours$ to $20\,hours$.

North's Opportunity Cost for Low-Quality Cars

$\frac{2}{3}$ high-quality cars, calculated from the ratio of $20\,hours$ to $30\,hours$.

South's Opportunity Cost for High-Quality Cars

$2$ low-quality cars, calculated from the ratio of $60\,hours$ to $30\,hours$.

South's Opportunity Cost for Low-Quality Cars

$0.5$ high-quality cars, calculated from the ratio of $30\,hours$ to $60\,hours$.

Comparative Advantage in Auto Manufacturing

Held by the North for high-quality cars (opportunity cost of $1.5$ low-quality cars vs. $2$ in the South) and by the South for low-quality cars (opportunity cost of $0.5$ high-quality cars vs. $\frac{2}{3}$ in the North).

Comparative Advantage (The Beatles Drummer Case)

The economic rationale explaining why having Ringo on drums makes sense even if Paul was a better drummer, because Paul's opportunity cost of drumming instead of singing, songwriting, and playing bass was too high.
