Conflict · Increasing returns from scale (Pin factory) leads to monopoly, which means Invisible Hand doesn't work
Invisible Hand requires many competitors in an industry.

Which one of the following ████ ██████████ █████████ ███ ████ █████ ██ ███ ████████

a

Mainstream economists have ██████ ███████ ████ ███████ ██ █████ ███ █████████ ██████████ ██████ ████ ███████████

Actually, P4 tells us that economists had always assumed that returns to scale were generally diminishing. In any case, even if (A) were supported it would be too narrow, as the assumption of economists is just one part of the story underlying how the Pin Factory came into the mainstream of economic thought.

b

The functioning of ███ █████████ ████ ██ ████████ █████████ ███████ ███████████ ███████ ███ ██ █████████ ████ ████████████ ██████

This is too narrow, as the reason the Invisible Hand was accepted is just one part of the story underlying how the Pin Factory came into the mainstream of economic thought.

c

Recent developments in ███████████ ████ ███████ ███ ███ ███████ ██ ██ ███████ ████ ████ ██████████ ████ ███ █████████ █████

The author never indicates that we can now model the Pin Factory “even more rigorously” than the Invisible Hand.

d

Adam Smith was ███ █████ █████████ ██ ██████████ ███ █ ██████ ███████ ███ ██████ ██████████ █████████████ ██ █████ ███ ██████ █████

The main point isn’t about Adam Smith’s understanding about the market economy and self interest. It’s about how the concept of the Pin Factory came into the mainstream of economic thought.

e

Economists have, until ████████ █████████ ██████ ██ ███████ ███ ███ ██████████ ███████ ██ █████ ██████ ██ ████ ███████████

This is the best answer. The “increasing returns to scale” refers to the Pin Factory concept. And the passage discusses how it was only recently that the Pin Factory has emerged in mainstream economic thought.
