Macquarie Group has said that it has launched a 'pay-as-you-go' model for its equity research. The company currently offers equities research as an all-in-one service, which means that a single payment will open up data provided by research. The new service, called Macquarie Dimension will see fund managers paying a small amount for an online subscription, and then pay for additional services as they want and need them. The launch comes ahead of an upheaval of the EU's trading rules.
