Governing Complexity: How Trust in Government Is Associated with Productive Capabilities
Using an unbalanced panel of 105 countries from 2004 to 2019 and Entropy Balancing for Continuous Treatments, this study finds that higher levels of institutional trust are robustly and positively associated with increased economic complexity, particularly in nations with strong infrastructure, democratic institutions, and effective governance.

Why do some nations seem to effortlessly build complex, high-tech economies while others remain stuck producing simple goods? For decades, economists have looked at the machinery of a country—its laws, its infrastructure, its schools—to find the answer. They have also looked at the invisible web of connections between industries, measuring how many different products a country can make and how difficult those products are to produce. This measure, known as economic complexity, acts like a fingerprint of a nation's productive soul. It reveals not just what a country sells, but the deep, often hidden knowledge required to make those things. But a crucial piece of the puzzle has remained largely unexamined: the human element. Specifically, how much do citizens trust their own government? If people believe their leaders are honest and effective, does that belief translate into a more sophisticated economy?
A team of researchers set out to explore this question, looking at the relationship between trust in government and the ability of nations to develop complex, knowledge-intensive industries. They gathered data from 105 countries over a fifteen-year period, from 2004 to 2019. Their goal was to see if a population's confidence in its public institutions was linked to the country's capacity to produce advanced goods, from intricate machinery to cutting-edge technology. The researchers were careful to account for the fact that rich countries often have both high trust and complex economies, which could simply be a coincidence. They used a sophisticated statistical method to level the playing field, comparing countries with different levels of trust while holding their income, population size, and natural resources constant. This allowed them to isolate the specific influence of trust itself.
The study found a clear and strong connection: higher levels of trust in government are associated with more complex and diversified economies. When citizens believe their government is credible and effective, their economies tend to produce a wider variety of sophisticated goods. This relationship held true even when the researchers looked at different layers of complexity. It wasn't just about exporting more diverse products; it was also linked to a country's technological sophistication and its capacity to generate new scientific knowledge. In short, trust appears to be a vital ingredient in the recipe for economic advancement, working alongside physical infrastructure and formal laws to help economies climb the ladder of development.
However, this trust does not work in a vacuum. The researchers discovered that the benefits of trust depend heavily on the environment in which it exists. In countries with strong infrastructure, effective governance, and democratic accountability, the link between trust and economic complexity is very strong. Trust acts as a force multiplier in these settings, helping to coordinate efforts and encourage long-term investment. But in countries where these supporting structures are weak, the relationship changes. The study noted a surprising finding in low-income nations, where higher trust was sometimes associated with less economic complexity. The authors suggest this might happen because, in some contexts, trust is placed in personal relationships or local leaders rather than in impersonal institutions that drive broad economic progress. Without the backing of strong, functional systems, trust alone may not be enough to spark the kind of structural transformation needed to build a modern economy.
The researchers also examined whether cultural factors, such as ethnic diversity or legal traditions, could explain the results. They found that while these deep-rooted characteristics do influence an economy, they do not override the power of trust. Even after accounting for a country's history, language, and legal system, the positive link between trusting the government and having a complex economy remained robust. This suggests that trust is a distinct and powerful driver of development, separate from the cultural or historical baggage a nation might carry.
Ultimately, the study paints a picture of development that goes beyond bricks and mortar. It suggests that the credibility of public action is a fundamental economic asset. When people trust their government, they are more likely to engage in the risky, long-term activities required to build complex industries, such as innovation and technological upgrading. The findings imply that for nations seeking to transform their economies, building trust is not just a political goal but an economic necessity. Yet, the researchers caution that this is a relationship of association, not a guaranteed cause-and-effect chain. Trust works best when it is part of a broader ecosystem of good governance and strong institutions. In the end, the path to a sophisticated economy requires both the hard work of building infrastructure and the soft power of earning the confidence of the people.
