Hanna is a Senior Economist. Her research uses game theory to study how technology influences network effects and interactions in the marketplace and how these changes affect business models. Much of her work focuses on competition between platforms, e.g. Apple’s iPhone vs. Android or eHarmony vs. Match. Most recently, her research applies platform competition concepts to analyze the development of digital currencies and blockchain technologies.
The technology behind blockchain has attracted a lot of attention. However, this technology is for the most part not well understood. There is no consensus on what benefits it may bring or on how it may fail.
Digital currencies have attracted strong interest in recent years and have the potential to become widely adopted for use in making payments. Public authorities and central banks around the world are closely monitoring developments in digital currencies and studying their implications for the economy, the financial system and central banks.
Given technological advances and the widespread use of the Internet, various digital currencies have emerged. In most cases, Internet platforms such as Facebook and Amazon restrict the functionality of their digital currencies to enhance the business model and maximize their profits. While platform-based digital currencies could increase the efficiency of retail payments, they could also raise some important policy issues if they were to become widely used outside of the platform. Thus, it is important to closely monitor the evolution of these digital currencies.
