The concept of creative destruction was popularised by Joseph Schumpeter and assumes that the economy is in a equilibrium. The “entrepreneur,” therefore, is an unbalancing factor that, through innovation, displaces the winners of the prevailing situation until then, generating a new equilibrium. This notion was criticized by other economists such as Friedrich Hayek and Israel Kirzner, who saw that the entrepreneur, far from being a disequilibrating factor, obtained its benefits by identifying the points of disequilibrium of a system and arbitrating between them.
The concept of “creative destruction,” on the other hand, focuses on businesses that go to waste from the irruption of the entrepreneur. This emphasis allows us to understand why there will be those who see with fear or disgust the very idea of innovation. In contrast, Hayek and Kirzner emphasize the benefits of the new equilibrium: greater efficiency in the allocation of resources and, consequently, a greater generation of wealth. The notion of Schumpeter allows us to explain why many oppose innovation, that of Hayek and Kirzner gives us reasons to move forward with it. Strictly speaking, in order for innovation not to cause damage at the aggregate level, it must satisfy the Kaldor-Hicks criterion, that is, the gains from innovation must be so high as to allow a hypothetical compensation to the ones who lost the new distribution of resources.
In short, the notion of creative destruction that both William Easterly and Acemoglu & Robinson use, although it might differs from Schumpeter’s, meets the said Kaldor-Hicks criterion. In these cases, innovation does not represent a social disvalue, but on the contrary it generates a benefit for the whole. Therefore, it goes without saying that any brake on an innovation of this nature generates social loss. At this point, if innovation -also called “creative destruction”- is systematically curtailed, in order to seek to protect activities that would otherwise be displaced, society may encounter the following scenarios: a relative delay (regarding its potential) of its development, or a stagnation, or setback. In all three scenarios, inequality in wealth and income increases, or society sees its standard of living delayed or diminished in a homogenous way. In this last case, the protected sectors are also harmed by the brakes imposed on innovation.
