This e-book aims to examine a number of policy tools that support public involvement and enhance public-private partnering in next generation infrastructures, tools which are generally overlooked. The papers in this issue explore the main domains where these complementary actions might take place. They encompass policies directed to the demand and supply sides of the market, information society and industrial innovation policies, additional measures that can be taken by local and regional public administrations and new policy tools to foster user empowerment.
