Classify the following as a government-enforced barrier to entry, a banker to entry that is not government-enforced, or a situation that does not involve a barrier to entry.
- A patented invention
- A popular but easily copied restaurant recipe
- An industry where economies of scale are very small compared to the size of
demand in the market - A well-established reputation for slashing prices in response to new entry
- A well-respected brand name that has been carefully built up over many years

(a)
The classification of the situation based on the given categories.
Answer to Problem 1SCQ
A patent invention is a government enforced barrier to entry.
