Today we have new tools based on computation. From them, we can get much richer and dynamic models that don’t require the simplified reductive assumptions of traditional economics. After the Global Financial Crisis there are paradigm shifts towards behavioral economics, psychology and complexity theory. Nobel prizes have been accredited to behavioral economists. Nobody believes in equilibrium, rational agents, perfect information and uncertainty reduced to a simple probability distribution anymore. Turner, Picketty and Stiglitz among others are fierce critiques of the standard economic models.
