profit driven to zero in a competitive market

No, if profit is close to zero then there would be no point in being in a market. Markets drive profits to the 'standard' risk adjusted ROI for the economy they operate in. In other words if you could run a gas station, a book store, a flower shop, or whatever, then you do whichever one gives the most profits.



If we're going to get into definitions, we can do that.

Since we are discussing economics, I do not feel the need to preface every use of jargon with disclaimers, though I can.

The relevant portion of Wikipedia's entry on (economics jargon) profit: https://en.wikipedia.org/wiki/Profit_%28economics%29#In_comp...

You can confirm this concept in any economics text. (economics jargon) Profit is driven to zero in a (economics jargon) competitive (economics jargon) market.


Economic profit is not the same thing as profit. In a pure economic debate you can drop it, but when talking about specific firms in a general context such as HN you really should clarify.

For everyone else: https://en.wikipedia.org/wiki/Profit_(economics) "Economic profit is similar to accounting profit but smaller because it subtracts off the total opportunity costs (not just the explicit costs, but also the implicit costs) of a venture to an investor.[1] Normal profit refers to zero economic profit.[2] A concept related to economic profit, and sometimes considered synonymous, is that of economic rent."

You can think of Economic profit as the 'standard' ROI you get in a given economy. Hypothetically Economic profit is also being driven to zero in a static economy, but that's a separate and long term thing.

PS: I am just being this clear because general HN readers are likely to miss the distinction.
