"The recent enphasis in Performativity of modern Finance is misleading. In a recent book of Donald Mckenzie ( An engine. Not a Camera ) to which I refered in yesterday´s article in EXPANSION, he defends the idea that modern Finance, the one that drifts away from Business towards Economics, is performative in the sense that it is not like any other piece of economic theory, which is limited to represent the world, but rather constructs the world."
