This role of entrepreneurs also depends on an abstract characteristic of technological knowledge: it works in a manner contrary to that of most goods, since it is more productive to the extent that it is more widespread in the population. This characteristic of the abstract nature of technological knowledge is related to the phenomenon of the combination of skills (matching of skills): the negative side of creative destruction lies in substitution phenomena (a computer program of inventory management increases the productivity of work saving the salaries of the army of employees who used to carry them with pencil and paper), but the positive side comes from the phenomena of complementarity.
As William Easterly exemplifies, the cardiac surgeon will be more productive in a first world hospital, where he will have specialized nurses, other qualified doctors like him, a sophisticated system of hospital administration, and so on, being the only cardiac surgeon in a hospital. city of the third world, where it does not have professionalized nurses, nor the help of other medical colleagues, working in a hospital in which he himself has to deal with administrative issues. If there were only substitution relations, it would be convenient for a doctor to practice his profession in the most remote place possible. However, as relations of complementarity of knowledge exponentially increase the productivity of the professionals involved, the doctor will find it more convenient to practice in a health center that has the largest number of doctors and paramedics possible.
The latter does lead to the phenomenon of “traps”: any rational agent, who maximizes the utility of their choices will be discouraged to deepen their studies if they perceive that they can not give any use to their education. There are the cases in which a person discovers that in his country there is no technology or the necessary number of professionals to develop a specific activity, or that, existing, you will find prohibited the exercise of their profession based on restrictions regarding their race, caste, social class, sex, etc. Since, rationally, a person who is included in a particular group under which he will be found forbidden or will be hindered the exercise of his profession, he will find as the most rational of their alternatives to abandon their studies, so that their chances of progress will no longer be limited only by legal or social barriers, but because of their lack of suitability for high-paying functions. Such are the so-called “poverty traps.”
There are also wealth traps. There are those cases in which the individual knows that he is within a favored group or in which he knows a large number of professionals and, therefore, invests time and money in his education because he knows that he has high chances of success, which will then be confirmed. Obviously, such phenomena of divergence generates another problem, addressed both by Easterly and by Daron Acemoglu & James Robinson, which is that of polarized societies.
Easterly affirms that it is the exchange of goods and services, through the mutual benefits that they report to the parties that participate in it, the main source of wealth generation. Where individuals are allowed to exchange, in a stable institutional framework with a stable currency, is where prosperity flourishes. However, Easterly recognizes that bad luck can devastate nations, as are the cases of geological and climatic phenomena such as earthquakes, tsunamis or mudslides, as well as recognizing that the situations of individuals involved in a poverty trap can only be resolved through an active public policy that not only provides education, but also establishes the conditions so that the recipients of that educational system can count on certain expectations that they will be able to apply that knowledge acquired through education and that, consequently, it is reasonable to study.
Just as the bad star can affect the economic performance of the countries, so can a favorable conjuncture, such as the case of a transitory improvement in terms of exchange of a given country. But this favorable circumstance can become a counter-march. Easterly explains that, for a simple statistical matter, it is very difficult for both a nation and an individual to always remain on the crest of the wave, over the years everything tends to return to the average. The problem occurs when a country -or a person, too- got used to a certain level of spending in the boom years and intends to maintain it through debt or emisionism. We come to the cases in which, according to Easterly, the government can “kill the growth.” Public debt and inflation generate capital consumption and, consequently, poverty.
Another way that governments have to discourage growth is through corruption. Not only because it means a transfer of resources from productive activities to unproductive activities, but because it also means a bad signal for citizens. However, in cases of corruption, as noted above, wealth at least changes hands. There is another case, even more pernicious, in which the government’s actions, whether motivated by corruption or inspired by good intentions, destroy wealth, without even redistributing it: this is the case of inconsistent public policies derived from highly polarized societies.
Public policies that aim to favor a given industry, but at the same time need to agree on measures with other sectors of the economy, whose purpose is to compensate for the losses generated by those policies, can lead to a tangle of inconsistent regulations that, instead of transfer riches from one sector to another, directly destroy them. For example: exchange controls harm the export sector, since they generate black markets. The exporters will have costs that will be partly quoted according to the black market prices (which are higher) and they will have to liquidate the value of their exports at the official exchange rate, which will be lower. Regulations of this kind may not involve acts of corruption, but they do destroy wealth, which there is no way to recover.
Easterly lists numerous examples of everything that needs to be done to destroy growth. However, there is something that deserves to be especially highlighted: the progress or stagnation of nations does not depend on educational, cultural or geographic factors, but rather on the incentive framework that predominates. This incentive framework will always be abstract, that is, it can be applied at any time and place.
