Talk:Agent-based computational economics

Untitled
Agent-Based Computational Economics (ACE) is now an active growing topic area. A Google search (5/1/2007) reveals 251,000 hits for this specific entry (see below). My ACE website happens to be the first entry that comes up under this search, because I have devoted an enormous amount of time to creating a useful resource portal for newcomers to ACE and to agent-based modeling (ABM) in general. Consequently, I would like to be able to point Wikipedia readers interested in learning more about this methodology to this resource site. The entire site is designed for self-study and use by long-distance learners. I am confused and disappointed that Wikipedia would choose to label a reference to such an educational site as "spammming".

 * Hi. If you had prepared correctly when entering the editor community at Wikipedia, you probably wouldn't be as confused as now. This entails a lot of reading about the do's and dont's, and many contributors have fallen at this hurdle.


 * First off, in your mind, please try to separate ACE as a topic or subject, and as an external project resource which you have been heavily involved in. The article cannot serve for both. That would be like saying "My website and the subject matter are one and the same" - your site can only be one example of the subject matter, surely?


 * Basically, your article may pass most Wikipedia guidelines on notability, I wouldn't particularly know. I have no argument there because that is not the issue. However, it is an absolute rule of Wikipedia, with regard to the already-mentioned (on your talk page) conflict of interest guidelines, that persons with a direct interest in the subject of an article should neither create nor edit it. It is deemed impossible for such actions to engender neutral point of view (NPOV) inclusions, another absolute imperative in Wiki articles.


 * For this reason alone, the article Agent-Based Computational Economics cannot exist in its current form. Other editors might be able to give it an NPOV makeover, but this would involve stripping it of all reference to ACE (your vested interest, I have to say), except if a valid external link were to be allowed within the article in the future. Considering that removal of your links from other articles has recently taken place due to conflict of interest or self-promotion concerns (spamming is perhaps too harsh a handle, on reflection) does not bode well in this direction.


 * None of this activity is meant in any way as a slur against your knowledge of the subject or personal integrity. The article contains a particular slant which makes it appear to be a vehicle for throughlinking to ACE (and it's also no reflection on the value or usefulness of your resource as an educational tool).


 * Wikipedia is not many things - it certainly does not exist to guide people to resources such as yours. Sometimes that could be a valid by-product when another properly NPOVed article has good reason to mention your resource within its page.


 * In closing my reply, I have to point out that you appear very proud of your creation at ACE, and probably rightly so. However, it just goes to illustrate that you can't possibly keep a neutral standpoint where it is concerned. I feel that deletion of the article can be the only course.

 * You are right that I had no idea regarding the various restrictions on Wikipedia editing. I should have done my homework.


 * I have now replaced all of my previously given external links with one external link to the homepage of the Society for Computational Economics, an international organization that is a member of the Association of Allied Social Sciences (ASSA).


 * It would certainly seem from other Wikipedia pages that links to major established organizations promoting general well-recognized fields of study are permitted. LT (5/1/07) Tesfatsion 04:49, 2 May 2007 (UTC)


 * The accompanying article has been made NPOV, sufficiently enough for me to withdraw my objections on the grounds of conflict of interest, including threat of speedy deletion. This does not relate to the article's notability; however, I do not feel qualified to assess this field of knowledge, and will leave others to decide on that. I am removing the tags to the article. Good luck. Ref (chew) (do) 05:17, 2 May 2007 (UTC)

A little nudge...
Hi. In the right direction, hopefully. Have tweaked the article to conform to the Manual of Style, created 'lead-in' separated from other headings, formalised References, added stub tag, and other stuff. I'll leave it to you now. Ref (chew) (do) 05:38, 2 May 2007 (UTC)

Marxist Economics
I don't have access to source #17. I did get #18 (at least pre-pub) ... I see no reference to Marxist economics there though. — Preceding unsigned comment added by 74.43.13.138 (talk) 03:46, 6 February 2012 (UTC)

Dr. Gallegati's comment on this article
Dr. Gallegati has reviewed this Wikipedia page, and provided us with the following comments to improve its quality:

"several mistakes: eg, for example in ACE events modeled being driven solely by initial conditions, whether or not equilibria exist or are computationally tractable, and in the modeling facilitation of agent autonomy and learning.[8]

look at WEHIA"

We hope Wikipedians on this talk page can take advantage of these comments and improve the quality of the article accordingly.

Dr. Gallegati has published scholarly research which seems to be relevant to this Wikipedia article:

Dr. Pellizzari's comment on this article
Dr. Pellizzari has reviewed this Wikipedia page, and provided us with the following comments to improve its quality:

"- Move footnote [1] to the previous sentence and remove "As such... it falls in the paradigm of CAS". In particular, ACE models may have agents who reacts to their environment or to the actions of peers but do not necessarily _adapt_ (nternally or externally). In other words, interesting dynamics may arise from the interactions of stubborn but stable agents who sense but do not adapt.  - I would replace "not real people" with "not necessarily representing real people". - Last sentence of paragraph 1, replace with "Such rules are usually simple or based on heuristics but could also be the result of optimization, realized through use of AI methods" - I'm fairly in disagreement with "ACE has a similarity to, and overlap with, game theory as an agent-based method for modeling social interactions."  Players in GT are typically much more rational and forward looking than agents in agent-based models. For example, it is true that Halpern 2008 discusses bounded rationality but only in "terms of agents who have limited computational power": there are many more ways routinely employed in ACE to model agents, who may use cheap heuristics (notice the difference with "limited computational power"), or have limited information or socio-cultural biases or be subject to imitation effects. It's not clear to me how/why all these variants would fit into "limited computational power"

All in all I would remove the whole paragraph "ACE jas a similiarity... autonomy and learning" - in "Example: finance": replace "choose from a set of possible forecasting..." with "choose from a limited set of cognitively simple forecasting...""

We hope Wikipedians on this talk page can take advantage of these comments and improve the quality of the article accordingly.

We believe Dr. Pellizzari has expertise on the topic of this article, since he has published relevant scholarly research:

No mention of Hicks
The first models of economies represented as strands of independent productive processes were established by Hicks long before computers became ubiquitous. The reference is in FCE Mexico books. He should be mentioned as reference is to standard economic theory rather than computing ideas. djb — Preceding unsigned comment added by 108.30.56.204 (talk) 00:02, 25 November 2016 (UTC)
