The Competition Commission has refused permission for Van Schaik to purchase Juta as it would lessen competition in the academic book market.
Van Schaik Publishers forms part of the Times Media Group, whereas Juta Bookshops is a division of Juta & Company.
The statement issued by the commission on Wednesday said the merger, while small, was not subject to compulsory notification but that the parties had voluntarily notified the commission of the transaction.
A questionnaire was submitted by the commission to students at the University of Stellenbosch, University of Cape Town, University of Johannesburg, Tshwane University of Technology Main and Arcadia Campus to determine the impact of the merger to competition in the sector.
The commission concluded that Van Schaik would obtain market power which would be detrimental to students by reducing choice and resulting in higher prices for academic books. – Sapa.
