Talk:Marginal efficiency of capital

Marginality

It would be nice to find a “reliable source” to explain why this is identified as the marginal efficiency. Any good economist would recognize the reason, but one wants to avoid charges of “original research”, and edit wars between good economists and not-so-good economists.

For now, I have added “Marginalism” to the “See also” section; at least that gives the untutored reader a bit more help in figuring-out the marginality here. —SlamDiego_←T 04:05, 15 February 2009 (UTC)

Not an orphan any more (I think...) added three more links and back links.. Perhaps some don't make absolute sense at first glance but this is a deep and subtle concept and is important.--Oracleofottawa (talk) 03:50, 28 September 2009 (UTC)

Okay, but the link from “Marginal utility” just didn't make good sense. (I began some remarks to your talk page before your note appeared here.) —SlamDiego_←T 04:05, 28 September 2009 (UTC

Thank you again Mr. Slam... But please read the second sentence again s l o w l y..--Oracleofottawa (talk) 04:18, 28 September 2009 (UTC)

I don't need to read slowly. It involved the word “perhaps”, did it not? —SlamDiego_←T 04:20, 28 September 2009 (UTC)

Slam your no Maynard Keynes...--Oracleofottawa (talk) 05:19, 29 September 2009 (UTC)

I don't know anyone who's unhappy about that. (And so much for your previous posturing.) —SlamDiego_←T 05:25, 29 September 2009 (UTC)

Now, as to those “See also” links: While there is some relationship between the MEC and marginal utility, this is simply because there is some relationship between any price and marginal utility. And if that more general relationship didn't hold, so that prices generally were otherwise explained, then the MEC would still be meaningful. We don't link reference to every sort of price to “Marginal utility”. —SlamDiego_←T 05:38, 29 September 2009 (UTC)
