Starting your own company is expensive in any country but Nigerian businessman Chidi-Martins Opara faced a hidden extra cost: the payment of bribes. The first hurdle was registering his small cleaning and pest control company. The official fee was less than 10,000 naira ($75), but Opara says he paid four times that amount in bribes. "You have to give money to the big officials so your papers will move faster. Otherwise your file gets 'lost'," he says.
