If you’re living in the Niger Delta in Nigeria, your best bet at a high-paying career is probably ‘artisanal refining’ — or, in plain language, stealing oil from pipelines.

The resulting oil spills damage the environment and cause severe health problems, but the Nigerian government has continually failed in their attempts to stop this theft.

They send in the army, and the army gets corrupted. They send in enforcement agencies, and the enforcement agencies get corrupted. What’s happening here?

According to Mushtaq Khan, economics professor at SOAS University of London, this is a classic example of ‘networked corruption’. Everyone in the community is benefiting from the criminal enterprise — so much so that the locals would prefer civil war to following the law. It pays vastly better than other local jobs, hotels and restaurants have formed around it, and houses are even powered by the electricity generated from the oil.

In today's episode, Mushtaq elaborates on the models he uses to understand these problems and make predictions he can test in the real world.

Some of the most important factors shaping the fate of nations are their structures of power: who is powerful, how they are organized, which interest groups can pull in favours with the government, and the constant push and pull between the country's rulers and its ruled. While traditional economic theory has relatively little to say about these topics, institutional economists like Mushtaq have a lot to say, and participate in lively debates about which of their competing ideas best explain the world around us.

The issues at stake are nothing less than why some countries are rich and others are poor, why some countries are mostly law abiding while others are not, and why some government programmes improve public welfare while others just enrich the well connected.

Mushtaq’s specialties are anti-corruption and industrial policy, where he believes mainstream theory and practice are largely misguided.

Mushtaq's rule of thumb is that when the locals most concerned with a specific issue are invested in preserving a status quo they're participating in, they almost always win out.

To actually reduce corruption, countries like his native Bangladesh have to follow the same gradual path the U.K. once did: find organizations that benefit from rule-abiding behaviour and are selfishly motivated to promote it, and help them police their peers.

Trying to impose a new way of doing things from the top down wasn't how Europe modernised, and it won't work elsewhere either.

In cases like oil theft in Nigeria, where no one wants to follow the rules, Mushtaq says corruption may be impossible to solve directly. Instead you have to play a long game, bringing in other employment opportunities, improving health services, and deploying alternative forms of energy — in the hope that one day this will give people a viable alternative to corruption.

In this extensive interview Rob and Mushtaq cover this and much more, including:

• How does one test theories like this?
• Why are companies in some poor countries so much less productive than their peers in rich countries?
• Have rich countries just legalized the corruption in their societies?
• What are the big live debates in institutional economics?
• Should poor countries protect their industries from foreign competition?
• How can listeners use these theories to predict which policies will work in their own countries?
