The divided city of Nogales represents the profound economic inequality between nations and the institutional factors driving this inequality. In the first chapter of Why Nations Fail, Acemoglu and Robinson compare how people live on either side of the border in Nogales, Arizona and Nogales, Sonora. People living on the US side earn about three times as much as those on the Mexican side for similar work. They’re also more likely to be educated and healthy. And unlike their counterparts across the border, they can trust their government to represent them democratically and provide them with basic services like clean water, safe roads, and a fair legal system.
In other words, Nogales, Arizona has a far higher standard of living than Nogales, Sonora. However, they share the same history, culture, and geography, so none of these factors can explain the differences between them. This is why Acemoglu and Robinson highlight political and economic institutions and the incentives they create: the US’s system of government gives its citizens political and economic opportunities that Mexico’s simply does not.
In fact, Nogales is really just an accessible example of the far graver inequalities that plague the world in the 21st century. Acemoglu and Robinson use it to ease their readers into a difficult topic and provide clear, intuitive evidence that institutional practices—and not geography or culture—are the real cause of global inequality.
Nogales Quotes in Why Nations Fail
The differences among nations are similar to those between the two parts of Nogales, just on a larger scale. In rich countries, individuals are healthier, live longer, and are much better educated. They also have access to a range of amenities and options in life, from vacations to career paths, that people in poor countries can only dream of. People in rich countries also drive on roads without potholes, and enjoy toilets, electricity, and running water in their houses. They also typically have governments that do not arbitrarily arrest or harass them; on the contrary, the governments provide services, including education, health care, roads, and law and order. Notable, too, is the fact that the citizens vote in elections and have some voice in the political direction their countries take.
The reason that Nogales, Arizona, is much richer than Nogales, Sonora, is simple; it is because of the very different institutions on the two sides of the border, which create very different incentives for the inhabitants of Nogales, Arizona, versus Nogales, Sonora. The United States is also far richer today than either Mexico or Peru because of the way its institutions, both economic and political, shape the incentives of businesses, individuals, and politicians. Each society functions with a set of economic and political rules created and enforced by the state and the citizens collectively. Economic institutions shape economic incentives: the incentives to become educated, to save and invest, to innovate and adopt new technologies, and so on. It is the political process that determines what economic institutions people live under, and it is the political institutions that determine how this process works.
