Hanna Halaburda is a Senior Analyst in the Currency Department. She is a game theorist whose primary research interests focus on two-sided markets, platform competition and the impact of technology on firms’ strategy. Specific topics include introduction and adoption of digital currencies. Hanna received her PhD in Economics from Northwestern University.
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.
