The role of public and private institutions in the world of art, their influence on the market, the international acquisition and sales circuits in which they move, the different agents involved in the management of funds and the criteria followed at the moment of selecting works to bring cohesion to a collection are the main subjects that will be analysed. Carlos Urroz, Director of Arco and Liber; María García - Yelo, Director of the Modern and Contemporary Art Department of Christie's; and Antonio Montes, collector will participate.
