Far from the custom of assigning to cultural factors, or educational, or geographic or relative to the particular constitution of the ruling elites, the three works reviewed – Institutions, Institutional Change and Economic Performance, by Douglass C. North; The Elusive Quest for Growth, by William Easterly and Why Nations Fail, by Daron Acemoglu & James A. Robinson, state an explanation of the progress and decline of nations articulated on abstract incentives, which serve as a structure in which frame the rational agent makes his choices. The four authors have a common reference to methodological individualism, but such an individual agent does not make decisions in a vacuum, but inserted within a framework of incentives.
That such incentives, to act as points of reference for individual action, should materialize historically, does not mean that such conditions for action come from a particular circumstance of time and place, but that they depend on an abstract structure that relates to different terms and that is present in every phenomenon of human interaction.
To finish, it is worth referring to the conclusions reached by North in his referenced work: the case of the two successive Spanish Americas, the Habsburg and the Bourbons. The first extended from the discovery and colonization of America to the early eighteenth century. The viceroyalties of America enjoyed great political autonomy – Spanish immigration had been little and a “Creole” elite had developed – and they were closed to trade, which was limited to the “export” of gold to Spain. With the arrival of the Bourbons at the beginning of the 18th century and the implementation of their Reforms – which from the economic point of view were a resounding success both in Spain and in America – the relationship was reversed: political power passed into the hands of the “Peninsular Spaniards” and an opening of a more fluid trade between the metropolis and its colonies was launched. North explains that the independence movements could be successful due to a transitory alliance between the sectors that wanted to return to the Habsburg system and those who wanted to deepen the modernizing and free-market impulse of the Bourbons. Once achieved independence, these two currents came into conflict, which, according to the author, would extend until today.
According to North’s thesis on Spanish America, there would be two political patterns in tension: on the one hand, an elitist politician who is open to the economy and on the other a “popular” current that is traditionally protectionist. In the second half of the 19th century, success belonged to the “Bourbon pattern” and, in the 20th Century, the “Habsburg pattern” prevailed. In terms of Acemoglu & Robinson, it would be the dispute between a combination of extractive political institutions with inclusive economic institutions and another combination of inclusive political institutions with extractive economic institutions. Of course, in practice, moments of extractive political and economic institutions were also known, as well as short-lived experiences of inclusive institutions, both politically and economically.
The notion of polarized societies used by Easterly can serve as a way to deepen this analysis. It is much clearer to find problems of countries with societies divided into distant and dissimilar regions, in which the policy is expressly articulated as a function of tribes or ethnic groups and which the dispute over public policies expressly favors or harms a another ethnic group. However, as it has been stated, it is not ethnicity or nationality that determines the low economic and institutional performance of a country, but the polarization structure itself, whatever the functions in which such polarization is expressed (language, religion, ethnicity, ideology, etc.). Understanding these latter is fundamental to be able to provide a common thread for a principle of solution.
Just as on the political level an express agreement can be reached on the way to choose who exercises public power and under what conditions, Easterly states a series of conditions related to economic institutions whose agreement would allow for economic growth, regardless of the region, culture, or education of the ruling class of each country. Throughout The Elusive Quest for Growth you can find mentioned to free trade as a main factor of progress, monetary stability and exchange freedom as examples of clear and equitable rules, a state that participates in large infrastructure works but that refrain from arbitrating in the distribution of economic rents among various groups, a low level of public indebtedness, stability in property rights and an independent justice that allows individuals to innovate and save, as well as support programs and incentives to members of society who are immersed in poverty traps.
As mentioned, many times the policy -especially when, in the terms of Acemoglu & Robinson, it is inclusive- consists of the composition of interests of various kinds for the purpose of articulating a government program. From the work of the authors commented here, it can be inferred that, just as there is an agreement on the political plane regarding the rules of the democratic game, which include periodic elections, limited re-elections and division of powers, among others, there should also be a consensus in a body of economic institutions that should be left out of political negotiation, so that economic policy is as neutral as possible against the conflicting interests of which a country with a polarized society is composed.
