Everything drug cartels do to survive and prosper they’ve learnt from big business – brand value and franchising from McDonald’s, supply chain management from Walmart, diversification from Coca-Cola. Whether it’s human resourcing, R&D, corporate social responsibility, off-shoring, problems with e-commerce or troublesome changes in legislation, the drug lords face the same strategic concerns companies like Ryanair or Apple. So when the drug cartels start to think like big business, the only way to understand them is using economics. In Narconomics, Tom Wainwright meets everyone from coca farmers in secret Andean locations, deluded heads of state in presidential palaces, journalists with a price on their head, gang leaders who run their empires from dangerous prisons and teenage hitmen on city streets - all in search of the economic truth.
