that insists on selling more than it buys, hoarding cash under the mattress. It works for a
while, but it can make neighbours resentful and limit variety at home.
2. Absolute Advantage Adam Smith (1776)
The Scene: Adam Smith, in The Wealth of Nations, challenges mercantilism. Core Idea:
Countries should produce what they can make more efficiently than others and trade for
the rest. Example: If India can produce 1,000 kg of tea with the same resources that the UK
uses to produce 500 kg, India has an absolute advantage in tea. Story Angle: Imagine two
friends one bakes better bread, the other brews better coffee. Instead of both trying to
do everything, they specialise and swap. Both end up happier (and better fed).
3. Comparative Advantage David Ricardo (1817)
The Scene: Ricardo takes Smiths idea further. Core Idea: Even if a country is better at
producing everything, it should still specialise in what its relatively best at where it has
the lowest opportunity cost. Example: If the UK is better at making both cloth and wine, but
its advantage in cloth is much greater, it should focus on cloth and trade for wine. Story
Angle: Think of a brilliant surgeon who is also a fast typist. Even though she types faster
than her assistant, its better for her to perform surgeries while the assistant types reports
because her time is more valuable in the operating room.
4. HeckscherOhlin Theory (Early 20th Century)
The Scene: Swedish economists Eli Heckscher and Bertil Ohlin bring in the idea of factor
endowments. Core Idea: Countries export goods that use their abundant resources and
import goods that use their scarce resources. Example: Oil-rich countries export petroleum;
labour-rich countries export textiles. Story Angle: Its like a village where one family has lots
of cows (milk products) and another has fertile orchards (fruits). Naturally, they trade milk
for apples.
5. Leontief Paradox (1950s)
The Scene: Economist Wassily Leontief tests the HeckscherOhlin theory on the US
economy and finds a surprise. Core Idea: The US, rich in capital, was exporting labour-
intensive goods and importing capital-intensive goods the opposite of what the theory
predicted. Story Angle: Its like discovering that the best baker in town is selling sandwiches
while buying bread from others. It made economists rethink assumptions.
6. Product Life Cycle Theory Raymond Vernon (1960s)
The Scene: Post-war America, booming with innovation. Core Idea: New products are
developed in advanced countries, exported when demand grows, and eventually produced
in developing countries as they mature. Stages:
1. Introduction Produced and consumed domestically.
2. Growth Exported to other developed nations.
