The retail sector has not yet reached a unified stance on the impact of e-commerce, it emerged at the last edition of the Mapic real estate fair in Cannes last week. 'Retailers and developers seem to be divided on their approach to online shopping,' commented François Ortalo-Magné, Director of Wisconsin School of Business Global Real Estate. 'Everyone knows that online will have a role to play in the retail process but there seems to be no real agreement on what role and what strategy to invent,' he noted.
