Classical thought originating in the 18th century, reprinted by several authors after the Keynesian revolution started in the second quarter of the 20th century.

«The motto for the elaboration of this text was related to the fact that, in our view, there is evidence that the world economic and financial model continues under the aegis of a paradigm that does not seem to have adherence to the reality that societies experience today . In light of the knowledge that we have today, the continuation of the compartmentalization of scientific knowledge used for the reflection and execution of the model used in the economic and financial management of societies becomes unsustainable. To this end, we will make use of the knowledge developed by neuroscience and behavioral economics.

As we will explore, this paradigm is supported, in its genesis, in classical thought originating in the 18th century, re-imagined by several authors in the post-Keynesian revolution that began in the second quarter of the 20th century. We will emphasize from this thought that the individual is considered to be an omniscient being, perhaps in rational terms, omnipotent, leading to the so-called Homo Economicus.

To this end, it is of interest, in the first instance, to try to understand classical thinking in its original form and later, in its more recent versions, in opposition to the Keynesian perspective of investment and, therefore, of the causes inherent to the decisions taken by the individual and what their consequences are. impacts on the crisis we are now experiencing. We will conclude with the theme of the efficiency of financial markets, as well as the role that the deregulation of the banking sector had in the crisis we are currently experiencing.” in Abstract
