ABSTRACT
The critical analysis compares the two economic approaches regarding human reality: first, a summary of the theoretical differences between the approaches, and second, a summary of the methodological differences, developing these in the particular case of the explanation of prices. Using praxeology and starting from Ludwig Von Mises' work, Israel Kirzner has established the lines along which to develop the concept the key concept of entrepreneurship. Gary Stanley Becker reduces economic behaviour to operating with elements that homo economicus can manage. Every action, whether it is social interaction or a market exchange, is carried out within some social institutions. The social institutions constitute the framework that sustains the social ‘edifice’. In praxeology, competition is a dynamic process of discovery: the discovery of the means and ends in the whole scope of application of entrepreneurship which, in other words, is the human world. Mises deals with causality from the point of view of praxeology.
