Here the price history of the comic book is analysed into three markets, that of the new, the collectors\u2019 market, and the investors\u2019. System dynamics is employed to model these markets, and different dynamic hypotheses are employed to distinguish between them in structural, as well as historical, terms. The model is tested against real-world data, and used to identify factors other than supply and demand that are important determinants of goods value. Conclusions are drawn with respect to the more general market for collectables.<\/p>","DOI":"10.4018\/ijsda.2013010103","type":"journal-article","created":{"date-parts":[[2013,4,9]],"date-time":"2013-04-09T15:31:17Z","timestamp":1365521477000},"page":"37-58","source":"Crossref","is-referenced-by-count":9,"title":["A System Dynamics Model of the American Collectable Comic Book Market"],"prefix":"10.4018","volume":"2","author":[{"given":"John","family":"Wyburn","sequence":"first","affiliation":[{"name":"Department of Computing and Mathematical Sciences, University of Glamorgan, Pontypridd, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul Alun","family":"Roach","sequence":"additional","affiliation":[{"name":"Department of Computing and Mathematical Sciences, University of Glamorgan, Pontypridd, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"ijsda.2013010103-0","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-6288.1983.tb00146.x"},{"key":"ijsda.2013010103-1","author":"J.Bails","year":"1965","journal-title":"The guidebook to comics fandom"},{"key":"ijsda.2013010103-2","first-page":"381","article-title":"The American comic book: 1929-present, a concise history of the field as of 2009","author":"R.
