Дарон Аджемоглу - Why Nations Fail

Killick somewhat understatedly remarks that this was an enterprise “whose viability was undermined by poor siting.” The footwear factory was one of many such projects, joined by the mango canning plant situated in a part of Ghana which did not grow mangos and whose output was to be more than the entire world demand for the product. This endless stream of economically irrational developments was not caused by the fact that Nkrumah or his advisers were badly informed or ignorant of the right economic policies. They had people like Killick and had even been advised by Nobel laureate Sir Arthur Lewis, who knew the policies were not good. What drove the form the economic policies took was the fact that Nkrumah needed to use them to buy political support and sustain his undemocratic regime.

Neither Ghana’s disappointing performance after independence nor the countless other cases of apparent economic mismanagement can simply be blamed on ignorance. After all, if ignorance were the problem, well-meaning leaders would quickly learn what types of policies increased their citizens’ incomes and welfare, and would gravitate toward those policies.

Consider the divergent paths of the United States and Mexico. Blaming this disparity on the ignorance of the leaders of the two nations is, at best, highly implausible. It wasn’t differences in knowledge or intentions between John Smith and Cortés that laid the seeds of divergence during the colonial period, and it wasn’t differences in knowledge between later U.S. presidents, such as Teddy Roosevelt or Woodrow Wilson, and Porfirio Díaz that made Mexico choose economic institutions that enriched elites at the expense of the rest of society at the end of the nineteenth and beginning of the twentieth centuries while Roosevelt and Wilson did the opposite. Rather, it was the differences in the institutional constraints the countries’ presidents and elites were facing. Similarly, leaders of African nations that have languished over the last half century under insecure property rights and economic institutions, impoverishing much of their populations, did not allow this to happen because they thought it was good economics; they did so because they could get away with it and enrich themselves at the expense of the rest, or because they thought it was good politics, a way of keeping themselves in power by buying the support of crucial groups or elites.

The experience of Ghana’s prime minister in 1971, Kofi Busia, illustrates how misleading the ignorance hypothesis can be. Busia faced a dangerous economic crisis. After coming to power in 1969, he, like Nkrumah before him, pursued unsustainable expansionary economic policies and maintained various price controls through marketing boards and an overvalued exchange rate. Though Busia had been an opponent of Nkrumah, and led a democratic government, he faced many of the same political constraints. As with Nkrumah, his economic policies were adopted not because he was “ignorant” and believed that these policies were good economics or an ideal way to develop the country. The policies were chosen because they were good politics, enabling Busia to transfer resources to politically powerful groups, for example in urban areas, who needed to be kept contented. Price controls squeezed agriculture, delivering cheap food to the urban constituencies and generating revenues to finance government spending. But these controls were unsustainable. Ghana was soon suffering from a series of balance-of-payment crises and foreign exchange shortages. Faced with these dilemmas, on December 27, 1971, Busia signed an agreement with the International Monetary Fund that included a massive devaluation of the currency.

The IMF, the World Bank, and the entire international community put pressure on Busia to implement the reforms contained in the agreement. Though the international institutions were blissfully unaware, Busia knew he was taking a huge political gamble. The immediate consequence of the currency’s devaluation was rioting and discontent in Accra, Ghana’s capital, that mounted uncontrollably until Busia was overthrown by the military, led by Lieutenant Colonel Acheampong, who immediately reversed the devaluation.

The ignorance hypothesis differs from the geography and culture hypotheses in that it comes readily with a suggestion about how to “solve” the problem of poverty: if ignorance got us here, enlightened and informed rulers and policymakers can get us out and we should be able to “engineer” prosperity around the world by providing the right advice and by convincing politicians of what is good economics. Yet Busia’s experience underscores the fact that the main obstacle to the adoption of policies that would reduce market failures and encourage economic growth is not the ignorance of politicians but the incentives and constraints they face from the political and economic institutions in their societies.

Although the ignorance hypothesis still rules supreme among most economists and in Western policymaking circles—which, almost to the exclusion of anything else, focus on how to engineer prosperity—it is just another hypothesis that doesn’t work. It explains neither the origins of prosperity around the world nor the lay of the land around us—for example, why some nations, such as Mexico and Peru, but not the United States or England, adopted institutions and policies that would impoverish the majority of their citizens, or why almost all sub-Saharan Africa and most of Central America are so much poorer than Western Europe or East Asia.

When nations break out of institutional patterns condemning them to poverty and manage to embark on a path to economic growth, this is not because their ignorant leaders suddenly have become better informed or less self-interested or because they’ve received advice from better economists. China, for example, is one of the countries that made the switch from economic policies that caused poverty and the starvation of millions to those encouraging economic growth. But, as we will discuss in greater detail later, this did not happen because the Chinese Communist Party finally understood that the collective ownership of agricultural land and industry created terrible economic incentives. Instead, Deng Xiaoping and his allies, who were no less self-interested than their rivals but who had different interests and political objectives, defeated their powerful opponents in the Communist Party and masterminded a political revolution of sorts, radically changing the leadership and direction of the party. Their economic reforms, which created market incentives in agriculture and then subsequently in industry, followed from this political revolution. It was politics that determined the switch from communism and toward market incentives in China, not better advice or a better understanding of how the economy worked.

WE WILL ARGUE that to understand world inequality we have to understand why some societies are organized in very inefficient and socially undesirable ways. Nations sometimes do manage to adopt efficient institutions and achieve prosperity, but alas, these are the rare cases. Most economists and policymakers have focused on “getting it right,” while what is really needed is an explanation for why poor nations “get it wrong.” Getting it wrong is mostly not about ignorance or culture. As we will show, poor countries are poor because those who have power make choices that create poverty. They get it wrong not by mistake or ignorance but on purpose. To understand this, you have to go beyond economics and expert advice on the best thing to do and, instead, study how decisions actually get made, who gets to make them, and why those people decide to do what they do. This is the study of politics and political processes. Traditionally economics has ignored politics, but understanding politics is crucial for explaining world inequality. As the economist Abba Lerner noted in the 1970s, “Economics has gained the title Queen of the Social Sciences by choosing solved political problems as its domain.”
