Research Information

Research Interests

Chatterjee's primary focus is business model innovation.

If a business opportunity is profitable, there is invariably an element of risk in it. Profit is the result of a firm's ability to take risks while avoiding the adverse impacts of risks. An innovative business model can allow a firm to take on risks that others avoid. This becomes vitally important for creating business models for a sustainable world and for tapping into the wealth potential at the bottom of the economic pyramid. This approach turns the conventional idea of looking for returns first and worrying about risks later on its head.
