Resource Dependence, Fiscal Accountability and Regional Diversification in Zambia: Subnational Evidence from a Mining Economy
This study challenges the deterministic subnational resource curse narrative in Zambia by demonstrating that while mining dependence is negatively associated with overall economic concentration across provinces, it does not significantly hinder non-extractive diversification when measured independently, suggesting that mineral development's impact depends on local linkages and fiscal institutions rather than extraction alone.

Imagine a country where the ground beneath the soil holds immense wealth, yet the people living on top of it struggle to build a stable, varied economy. This is the puzzle of the "resource curse," a idea that suggests nations rich in minerals often end up poorer or less developed than those without them. For decades, economists have debated whether digging up gold, oil, or copper inevitably leads to corruption, economic stagnation, or a lack of other industries. But this story often gets told as if it happens to a whole country at once, ignoring the fact that a mine is usually just in one specific town or region. In reality, the benefits and costs of mining are not spread evenly. Some areas might boom while others nearby remain poor, and the money generated often flows to national capitals rather than staying local. This raises a critical question for places like Zambia, a nation famous for its copper: does the presence of a massive mine actually stop a local region from developing other types of businesses, or is the relationship more complicated than a simple cause-and-effect story?
A recent study by Obby Phiri, a researcher at the University of Westminster, takes a close, ground-level look at this question within Zambia. Instead of looking at the country as a single block of data, the study examines ten different provinces over a six-year period from 2016 to 2021. The researcher gathered official government records on how much money each province made from different industries, from farming and manufacturing to services and mining. The goal was to see if provinces with a higher share of mining income were less diverse in their other economic activities. To do this, the study used a method that measures how concentrated an economy is; if one industry takes up almost all the space, the economy is considered "concentrated," whereas a mix of many different industries is "diversified." The study also looked at how local governments were funded, checking if regions dependent on mining were also dependent on money sent down from the central government, which could weaken their ability to manage their own budgets.
The initial picture seemed to confirm the old warning. When the researcher looked at the data across all provinces at once, the ones with the most mining activity appeared to be the least diverse. It looked like the mining sector was crowding out everything else, leaving those regions with a single, fragile economic pillar. However, the study dug deeper to see if this was a real pattern or just a result of the numbers. The researcher realized that because mining was so huge in some places, it mathematically forced the "concentration" score to be high, regardless of what was happening in the rest of the economy. It was like saying a room is crowded just because one giant piece of furniture took up half the space, even if the rest of the room was filled with many different, smaller items.
When the researcher adjusted the math to remove the mining sector entirely and looked only at the non-mining businesses, the story changed completely. In the provinces with the most mining, the remaining economy was actually becoming more diverse, not less. The presence of the mine did not seem to be killing off other industries; in fact, the non-mining sectors were showing signs of variety. This suggests that the "curse" might not be about mining destroying other businesses, but rather about how we measure success. A region can be dominated by one giant industry and still have a lively, varied set of smaller businesses supporting it. The study found that the strong negative link between mining and diversity disappeared once the researcher accounted for the fact that one province, the North-Western, was so heavily focused on mining that it skewed the entire national picture. Without that one extreme example, the data showed no clear evidence that mining was actively suppressing other economic growth within the provinces.
The study also investigated whether the way money was managed played a role. There was a theory that mining regions might become less active with their finances, relying too much on handouts from the central government and failing to collect their own taxes, which would then stop them from building a diverse economy. The researcher checked the audit records of local councils to see if mining areas were indeed more dependent on central transfers. The evidence did not support this idea. The data showed no clear link between being rich in minerals and being dependent on outside money. In Zambia, the system of collecting and sharing money is complex; sometimes mining towns have strong local tax bases because of the wealth generated, while non-mining rural areas might rely heavily on central support. This means the "fiscal trap" theory, which suggests mining automatically weakens local government accountability, does not hold up in this specific context.
Ultimately, the research suggests that the story of the resource curse is not a simple rule that applies everywhere. It is not a fact that mining inevitably leads to a lack of diversity or poor local governance. Instead, the outcome depends heavily on the specific geography and the institutions in place. The study highlights that while mining regions might look concentrated on paper, the non-mining parts of their economies can be vibrant and growing. The real challenge for places like Zambia is not just about reducing the size of the mining sector, but about ensuring that the wealth generated builds strong local connections, creates good jobs, and supports accountable local governments. The findings urge policymakers to look beyond simple statistics and focus on whether mining is actually helping to build a resilient, capable local economy that can thrive even after the minerals are gone.
