«[In] the face of crisis, we felt abandoned by conventional tools. [...] The key lesson [...] is the danger of relying on a single tool, methodology or paradigm. The atomistic, optimising agents underlying existing models do not capture behavior during a crisis period. Agent-based modelling [...] allows for more complex interactions between agents. [...] we need to better integrate the crucial role played by the financial system into our macroscopic models.» Jean-Claude Trichet, Ancien président de la BCE, 18 Novembre 2010.
«Although this crisis in economics is a threat for some, for others it is an opportunity – an opportunity to make a great leap forward, as Keynes did in the 1930s. For the students in this room, there is the chance to rethink economics with as clean a sheet of paper as you are ever likely to find. That is perhaps why the numbers of students applying to study economics has shot up over recent years. This is one of the silver linings of the crisis. No discipline could ask for a better endowment.» Andrew G Haldane, économiste en chef de la Banque d’Angleterre, The dappled world, GLS Shackle Biennial Memorial Lecture 10 November 2016.
