Risco, incerteza e expectativa na dinâmica dos eventos de uma economia capitalista na perspectiva de Keynes e Knight

Abstract

The main objective of this article is to discuss under the aegis of the concepts of risk, uncertainty and expectation, the dynamics of economic events and how they influence their behavior, based on this conception by John Maynard Keynes and Frank Hyneman Knight. The main conclusion is that the phenomenon of economic crises is historically inseparable from the capitalist economy. Thus, it is undeniable that the concept of risk and uncertainty is observed by the economy and that, even when the economic agents act rationally when faced with ex ante decision-making in an environment of uncertainty, the economy will still be susceptible to the (negative) effects of a crisis, since a state of euphoria, coupled with the irrational conduct of the economic agents, may provoke a situation of economic, financial, political and social instability as a an ex post result.
