will be much better off by setting up institutions that are extractive. When there is conflict over institutions, what happens depends on which people or group wins out in the game of politics—who can get more support, obtain additional resources, and form more effective alliances. In short, who wins depends on the distribution of political power in society.
The political institutions of a society are a key determinant of the outcome of this game. They are the rules that govern incentives in politics. They determine how the government is chosen and which part of the government has the right to do what. Political institutions determine who has power in society and to what ends that power can be used. If the distribution of power is narrow and unconstrained, then the political institutions are absolutist, as exemplified by the absolutist monarchies reigning throughout the world during much of history. Under absolutist political institutions such as those in North Korea and colonial Latin America, those who can wield this power will be able to set up economic institutions to enrich themselves and augment their power at the expense of society. In contrast, political institutions that distribute power broadly in society and subject it to constraints are pluralistic. Instead of being vested in a single individual or a narrow group, political power rests with a broad coalition or a plurality of groups.
There is obviously a close connection between pluralism and inclusive economic institutions. But the key to understanding why South Korea and the United States have inclusive economic institutions is not just their pluralistic political institutions but also their sufficiently centralized and powerful states. A telling contrast is with the East African nation of Somalia. As we will see later in the book, political power in Somalia has long been widely distributed—almost pluralistic. Indeed there is no real authority that can control or sanction what anyone does. Society is divided into deeply antagonistic clans that cannot dominate one another. The power of one clan is constrained only by the guns of another. This distribution of power leads not to inclusive institutions but to chaos, and at the root of it is the Somali state’s lack of any kind of political centralization, or state centralization, and its inability to enforce even the minimal amount of law and order to support economic activity, trade, or even the basic security of its citizens.
Max Weber, who we met in the previous chapter, provided the most famous and widely accepted definition of the state, identifying it with the “monopoly of legitimate violence” in society. Without such a monopoly and the degree of centralization that it entails, the state cannot play its role as enforcer of law and order, let alone provide public services and encourage and regulate economic activity. When the state fails to achieve almost any political centralization, society sooner or later descends into chaos, as did Somalia.
We will refer to political institutions that are sufficiently centralized and pluralistic as inclusive political institutions. When either of these conditions fails, we will refer to the institutions as extractive political institutions.
There is strong synergy between economic and political institutions. Extractive political institutions concentrate power in the hands of a narrow elite and place few constraints on the exercise of this power. Economic institutions are then often structured by this elite to extract resources from the rest of the society. Extractive economic institutions thus naturally accompany extractive political institutions. In fact, they must inherently depend on extractive political institutions for their survival. Inclusive political institutions, vesting power broadly, would tend to uproot economic institutions that expropriate the resources of the many, erect entry barriers, and suppress the functioning of markets so that only a few benefit.
In Barbados, for example, the plantation system based on the exploitation of slaves could not have survived without political institutions that suppressed and completely excluded the slaves from the political process. The economic system impoverishing millions for the benefit of a narrow communist elite in North Korea would also be unthinkable without the total political domination of the Communist Party.
This synergistic relationship between extractive economic and political institutions introduces a strong feedback loop: political institutions enable the elites controlling political power to choose economic institutions with few constraints or opposing forces. They also enable the elites to structure future political institutions and their evolution. Extractive economic institutions, in turn, enrich the same elites, and their economic wealth and power help consolidate their political dominance. In Barbados or in Latin America, for example, the colonists were able
