The main hypotheses were: (a) potential sellers will underestimate information's value compared to that of material goods; (b) when potential buyers' involvement is high (that is high investment and high risk), sellers will demand even lower prices for information; (c) some important current functions and meanings of information are not assimilated in social representations of information; (d) by contrast, participants must overvalue the remuneration of professionals producing pure information (invention) compared to those who apply this information to produce material goods. An experimental study confirmed hypotheses (a) and (b). A second study to investigate the structure of information's social representations showed that the representation's central core is mainly composed of categories referring to traditional media, functions and technologies; contemporary functions and technologies are less frequent or absent. A third experimental study confirmed hypothesis (d).<\/jats:p>","DOI":"10.1177\/0165551508094936","type":"journal-article","created":{"date-parts":[[2008,11,21]],"date-time":"2008-11-21T20:56:08Z","timestamp":1227300968000},"page":"153-164","source":"Crossref","is-referenced-by-count":1,"title":["Valuing and representing information: the paradox of undervaluing information and overvaluing information producers"],"prefix":"10.1177","volume":"35","author":[{"given":"Maria","family":"Sakalaki","sequence":"first","affiliation":[{"name":"Department of Psychology, Panteion University of Social and Political Sciences, Athens, Greece,"}]},{"given":"Smaragda","family":"Kazi","sequence":"additional","affiliation":[{"name":"Department of Psychology, Panteion University of Social and Political Sciences, Athens, Greece"}]}],"member":"179","published-online":{"date-parts":[[2008,11,21]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/0268-4012(91)90006-X"},{"key":"atypb2","volume-title":"Pouvoir, information, \u00e9conomie","author":"Y.
